Referring to FIG. 8, in the mobile communication terminal according to the present invention, the charger 200 can generate power using an external magnetic field. The power generated by the charging unit 200 may be supplied to the battery 270 under the control of the controller 180. In addition, the magnitude of the power supplied to the battery 270 may vary depending on the control of the controller 180. [

The charging unit 200 includes a coil 510 for generating an AC current derived from an external magnetic field, a rectifying unit 520 for converting an AC current generated by the coil 510 into a DC current, And a power supply unit 530 for supplying the DC current rectified by the rectification unit 520 to the battery 270 according to the control.

The charging unit 200 may further include an information detector 540 that acquires information on the connected battery 270 and / or intensity information of the external magnetic field.

The magnetic field generation unit 400 can generate the external magnetic field. Here, the magnetic field generator 400 may be a wireless charger physically separated from the mobile communication terminal 100.

The magnetic field generator 400 includes a high frequency generator 410 that receives power from a commercial AC power source 430 supplying power of 110V or 220V and outputs a high frequency pulse through a high speed switching operation, And a coil 420 for receiving a high frequency pulse generated by the unit 410 to form a magnetic field.

The coil 420 of the magnetic field generating unit 400 may be referred to as a primary coil and the coil 510 of the charging unit 200 may be referred to as a secondary coil.

When a magnetic field is generated in the coil 420 of the magnetic field generating unit 400, a high frequency alternating current can be induced in the coil 510 of the charging unit 200 according to the linkage of the generated magnetic field.

When an alternating current is induced in the coil 510 of the charger 200, the induced alternating current may be rectified to a direct current in the rectifying unit 520.

The power supply unit 530 may supply the DC current rectified by the rectification unit 520 to the battery 270 connected to the controller 180 under the control of the controller 180.

Through this process, the battery 270 can be charged in a wireless manner.

Meanwhile, the present invention will be described by way of example of a wireless charging system according to a magnetic induction system, but the present invention can be applied not only to a magnetic induction system but also to a resonance induction system.

For example, when the present invention is applied to the resonance induction method, the coil for transmitting power, that is, the coil 420 of the magnetic field generator 400 and the coil for receiving power, that is, the coil 510 of the charger 200, It is possible to form a resonance between the resonators.

The wireless charging system described below can be applied to both the magnetic induction system and the resonance induction system unless otherwise described.

The information detecting unit 540 can detect information on the strength of the magnetic field generated by the magnetic field generating unit 400 and can detect information on the connected battery 270.

The information detecting unit 540 may include a first detecting unit capable of detecting the intensity of the magnetic field and a second detecting unit capable of detecting information of the battery 270 although not shown.

Meanwhile, some or all of the charging unit 200 of the mobile communication terminal 100 may be included in the power supply unit 190 of FIG.

In addition, a part or all of the charger 200 can be configured as a charge IC.

The power supply unit 530 not only supplies power to the battery 270 in the charging mode for charging the battery 270 but also supplies power to the mobile communication terminal 100 for driving the mobile communication terminal 100. [ It is also possible to supply electric power to the components of the apparatus.

8, the information detecting unit 540 may be included in the control unit 180, although the information detecting unit 540 may be included in the control unit 180. FIG. That is, the controller 180 may be able to detect information about the strength of the external magnetic field and information on the connected battery 270. [

9 and 10, the magnetic field generator 400 may be manufactured in the form of a pad. 9, since the user simply places the mobile communication terminal 100 on the pad-shaped magnetic field generating unit 400, the mobile communication terminal 100 can be moved to the mobile communication terminal 100, It is possible to charge the battery 270 of the battery 100.

In the case where the present invention is applied to the resonance induction method, the battery 270 of the mobile communication terminal 100 can be charged even if the mobile communication terminal 100 is physically separated from the magnetic- have.

In the mobile communication terminal 100 according to the present invention, the charging rate of the battery 270 can be adjusted according to information detected by the information detector 540. This will be described in more detail below.

11, it is determined whether the current mode is the charging mode for charging the battery 270 (S1100). If the mode is the charging mode, the external magnetic field provided from the outside (provided from the magnetic field generating unit 400) Power can be generated (S1110). A method of generating electric power by an external magnetic field has been described in detail with reference to FIG. Here, it is described that electric power is generated by using a magnetic field after determining whether it is a charging mode. However, it is also possible to generate electric power corresponding to a magnetic field when it is not necessary to determine whether or not it is a charging mode. Hereinafter, for the sake of convenience of explanation, an example will be described in which power is generated after determining whether or not the battery is in the charging mode.

Then, the information detector 540 may acquire the information of the connected battery 270 (S1120). The information detecting unit 540 may obtain the information of the battery 270 from the IC of the battery 270. [

In detail, as in the case of FIG. 12, the battery 270 may include a plurality of terminals 273. FIG. The plurality of terminals 273 include a power terminal 271 for receiving power for charging and outputting power for driving the mobile communication terminal 100 and an information terminal 272 for reading information of the battery 270 ).

The information terminal 272 of the battery 270 may be electrically connected to the battery IC 274 mounted inside the battery 270.

The mobile communication terminal 100 can acquire the information of the battery 270 from the battery IC 274 through the information terminal 272 of the battery 270. [ Here, it is described that the information of the battery 270 is acquired (S1120) after the power is generated by using the external magnetic field (S1110). However, the power generation by using the external magnetic field (S1110) (S1120) can be performed at substantially the same timing, or it is also possible to generate electric power using an external magnetic field (S1110) after acquiring information on the battery 270 (S1120) .

More specifically, when the battery 270 is mounted on the mobile communication terminal 100, the battery terminal 371 disposed on the housing 240 and the information terminal 272 of the battery 270 may be electrically connected. The information detecting unit 540 can obtain information on the battery 270 from the battery IC 274 through the battery terminal 371 and the information terminal 272. [

The information of the battery 270 detected by the information detecting unit 540 may include various information such as the manufacturer information of the battery 270, the manufacturing date information, and the serial number information, as in the case of FIG.

In addition, the information on the battery 270 may preferably include battery capacity information and battery current information.

Here, the current information of the battery may include the maximum allowable current (MaxA) information of the battery, as in the case of FIG. 13 (A). Here, the maximum allowable current (MaxA) of the battery may mean the maximum value of the current usable by the battery. Therefore, a large maximum allowable current of the battery may mean that the battery can be charged with a relatively large current.

Alternatively, as in the case of FIG. 13B, the current information of the battery may include current range information of the battery. Here, the maximum value of the current range information of the battery, for example, 1.8 A, may mean the maximum value of the current that can be used by the battery. Therefore, a large maximum value of the current range information of the battery may mean that the battery can be charged with a relatively large current.

Hereinafter, the current information of the battery will be collectively referred to as a maximum allowable current MaxA. For example, in the case of FIG. 13 (B), 1.8 A can correspond to the maximum allowable current (MaxA).

After the information of the battery 270 is acquired in step S1120, it is determined whether the currently connected battery 270 is a fast rechargeable battery in step S1130.

As a result of the determination, if the currently connected battery 270 is a fast rechargeable battery, the battery 270 is charged at a high speed (S1140). If the currently connected battery 270 is not a fast rechargeable battery, (S1150).

For example, when the first battery 270A having the maximum allowable current MaxA is mounted on the mobile communication terminal 100 as in the case of FIG. 14A, the charging speed of the first battery 270A When the second battery 270B having the maximum allowable current MaxA greater than aA is attached to the mobile communication terminal 100 as in the case of FIG 14B, 270B is the second rate. Here, the capacities of the first battery 270A and the second battery 270B may be the same.

In this case, since the maximum allowable current of the second battery 270B is larger than that of the first battery 270A, it is possible to supply a relatively large current to the second battery 270B as compared with the first battery 270A have.

Accordingly, the second speed, which is the charging speed of the second battery 270B, may be faster than the first speed, which is the charging speed of the first battery 270A. If the current capacities of the first and second batteries 270A and 270B are the same, the time required to charge the second battery 270B may be shorter than the time required to charge the first battery 270A.

Assuming that charging of the first and second batteries 270A and 270B starts from the time t0 as in the case of FIG. 15A, the maximum allowable current MaxA ) Is aaA and the charging current supplied to the second battery 270B having the maximum allowable current (MaxA) larger than aA is bbA, which is larger than aaA. Here, the charging current may refer to the current supplied to the first and second batteries 270A and 270B during the charging period.

That is, when the maximum allowable current MaxA of the battery 270 is large, the amount of current supplied to the battery 270 is increased. On the contrary, when the maximum allowable current MaxA of the battery 270 is small, It is possible to reduce the amount of current per unit time supplied to the power supply unit 270.

If the magnitude of the power supplied to the battery 270, for example, the magnitude of the current, is increased when the battery 270 is relatively large in the maximum allowable current MaxA, the charging speed of the battery 270 is increased, Can be reduced.

The magnitude of the power supplied to the second battery 270B in the charging mode may be approximately N times (N is a natural number equal to or greater than 2) the magnitude of the power supplied to the first battery 270A in the charging mode.

For example, assuming that the maximum allowable current of the first battery 270A is 1.8A and the maximum allowable current of the second battery 270B is 3.6A, the first battery 270A is supplied with the first battery 270A The charging current may be 1.8A and the charging current supplied to the second battery 270B may be 3.6A. Assuming that the maximum allowable current of the first battery 270A is 1.8A and the maximum allowable current of the second battery 270B is 4.0A, the charge current supplied to the first battery 270A during the charge mode And the charge current supplied to the second battery 270B may be 3.6A. Alternatively, assuming that the maximum allowable current of the first battery 270A is 1.8A and the maximum allowable current of the second battery 270B is 6.0A, the charge current supplied to the first battery 270A during the charge mode And the charge current supplied to the second battery 270B may be 5.4A.

If the magnitude of the power supplied to the battery 270 (or the magnitude of the current) is increased by N times according to the type of the battery 270, for example, the maximum allowable current of the battery 270, Can be controlled easily.

In addition, if the magnitude of the power supplied to the battery 270 (or the magnitude of the current) is increased N times according to the type of the battery 270, the charging speed of the battery 270 may also be increased N times. For example, when the power supplied to the battery 270 is doubled, the charging speed of the battery 270 is also doubled.

As described above, the magnitude of the electric power per unit time (for example, unit time) supplied to the battery 270 according to the type of the battery 270, the maximum allowable current MaxA of the battery 270, 270 can be adjusted.

In other words, it is as follows.

The power supplied to the first battery 270A when the first battery 270A is attached to the mobile communication terminal 100 according to the present invention is referred to as a first power and the power supplied to the mobile communication terminal 100 according to the present invention Assuming that the power supplied to the second battery 270B is the second power when the second battery 270B having a different maximum allowable current from the first battery 270A is installed, It can be different. Preferably, when the maximum allowable current of the second battery 270B is greater than the maximum allowable current of the first battery 270A, the second power is greater than the first power.

15, assuming that the charging of the second battery 270B having the relatively large maximum allowable current MaxA is completed during the period from the time t0 to the time t1, the charging current supplied to the second battery 270B is t1 It can be gradually decreased in the vicinity of the viewpoint.

15 (B), the charging voltage of the second battery 270B may gradually increase to the maximum voltage Vmax during the period from the time t0 to the time t1.

Here, the charging voltage of the battery 270 may be the voltage of the electric power stored in the battery 270.

As in the case of FIG. 15B, maintaining the Vmax after the charging voltage of the second battery 270B rises to the Vmax at the time t1 means that the charging of the second battery 270B is completed at the time t1 .

On the other hand, in the case of the first battery 270A in which the maximum allowable current MaxA is smaller than that of the second battery 270B, since the charging current is also smaller than that of the second battery 270B, And may be supplied to the first battery 270A. For example, the charging current of aaA can be continuously supplied to the first battery 270A during the period from the time t1 to the time t2.

As described above, in the case of the first battery 270A in which the maximum allowable current MaxA is smaller than that of the second battery 270B, charging can be performed during a period from the time t0 to the time t2. In addition, the charging current supplied to the first battery 270A may gradually decrease at the time point t2.

In addition, the charging voltage of the first battery 270A may gradually increase to the maximum voltage Vmax during the period from time t0 to time t2 as shown in FIG. 15 (B).

15, when the maximum allowable current MaxA of the battery 270 is relatively large, the amount of current supplied to the battery 270 may be increased to increase the charging speed of the battery 270 will be.

Meanwhile, the magnetic field generator 400 can communicate with the communication unit 200. The following is a look at this.

16, the magnetic field generating unit 400 may include a high frequency generating unit 410, a coil 420, a rectifying unit 440, a controller 450, and a communication unit 460. In addition, the charging unit 200 may further include a communication unit 550.

The rectifying unit 440 of the magnetic field generating unit 400 can rectify the AC current received from the commercial AC power source 430 into a DC current and output the DC current.

The direct current output by the rectifying unit 440 of the magnetic field generating unit 400 may be used as electric power for driving the components of the magnetic field generating unit 400. For example, the current output by the rectifying unit 440 may be supplied to the control unit 450 and the communication unit 460 of the magnetic field generating unit 400.

The communication unit 460 of the magnetic field generation unit 400 can communicate with the communication unit 550 of the charging unit 200. [

The controller 450 of the magnetic field generator 400 may control the operation and the function of the magnetic field generator 400.

The communication unit 550 of the charging unit 200 can transmit the charging information of the battery 270 to the communication unit 460 of the magnetic field generating unit 400 under the control of the controller 180. [

For example, as in the case of FIG. 17, it can be determined whether or not the charging of the battery 270 is completed after the normal charging (S1150) or the fast charging (S1140) (S1700). For example, it is possible to judge whether or not the charging is completed by judging whether or not the control unit 180 has reached the voltage Vmax as in the case of Fig. 15 (B).

As a result of the determination, when the charging of the battery 270 is completed, the communication unit 550 of the charging unit 200 can transmit the charging completion signal (S1710) under the control of the controller 180. [

Then, the communication unit 460 of the magnetic field generating unit 400 receives the charging completion signal, and the controller 450 controls the high frequency generating unit 410 based on the charging completion signal received through the communication unit 460 Generation of the high-frequency AC signal (high-frequency pulse) can be stopped (S1720).

In this way, it is also possible to stop the operation of the magnetic field generator 400 upon completion of charging the battery 270.

The charging completion signal transmitted from the communication unit 550 of the charging unit 200 may be regarded as a signal for interrupting the supply of the external magnetic field when the charging of the battery 270 is completed.

On the other hand, when the maximum allowable current of the battery 270 is larger than a preset threshold current, it is possible to charge the battery 270 at a high speed by increasing the amount of power supplied to the battery 270, Do. The following is a look at this. In the following FIG. 18, the description of the same elements as those of FIG. 11 is omitted.

18, it is determined whether or not the current mode is the charging mode for charging the battery 270 (S1100). In the charging mode, power is generated using the external magnetic field provided from the outside (S1110) The information of the battery 270 connected by the detecting unit 540 may be acquired (S1120).

After acquiring the information of the battery 270 (S1120), it can be determined whether or not the maximum allowable current of the currently connected battery 270 is equal to or greater than a preset threshold current (S1800).

As a result of the determination, if the maximum allowable current of the currently connected battery 270 is less than the threshold current, the first power may be supplied to the battery 270 to charge the battery 270 at the first speed (general charge, S1820) .

Alternatively, if the maximum allowable current of the currently connected battery 270 is greater than the threshold current, the battery 270 may be supplied with a second power greater than the first power to charge the battery 270 at a second rate higher than the first rate. It is possible to perform charging (fast charging, S1810).

For example, as in the case of FIG. 19, when the maximum allowable current (MaxA) of the connected battery is greater than a preset threshold current (ThA), the battery 270 is charged in the fast charge mode, It is possible to charge the battery 270 in the normal charging mode when the charging current MaxA is smaller than the preset threshold current ThA.

Alternatively, as in the case of FIG. 20, the threshold current may include the first, second, and third threshold currents ThA1, ThA2, ThA3.

In this case, when the maximum allowable current of the battery 270 is smaller than the first threshold current ThA1, the first power (or the first current) is supplied to the battery 270 to charge the battery 270 at the first speed can do.

When the maximum allowable current of the battery 270 is larger than the first threshold current ThA1 and smaller than the second threshold current ThA2, the second power (or the second current larger than the first current) The battery 270 can be charged at a second rate faster than the first rate.

(Or a third current larger than the second current) larger than the second power when the maximum allowable current of the battery 270 is larger than the second threshold current ThA2 and smaller than the third threshold current ThA3, The battery 270 can be charged at a third rate faster than the second rate.

When the maximum allowable current of the battery 270 is larger than the third threshold current ThA2, the fourth power (or the fourth current larger than the third current) larger than the third power is supplied to the battery 270, ) At a fourth speed faster than the third speed.

In FIG. 20, although the threshold current is divided into three stages in total, the number of threshold currents can be variously changed.

Meanwhile, it is possible to adjust the charging speed of the battery 270 according to the intensity of the external magnetic field generated by the magnetic field generator 400. The following is a look at this.

Information on the external magnetic field strength generated by the magnetic field generating unit 400 can be acquired by the information detecting unit 540 of the charging unit 200. [ If the information detector 540 is included in the controller 180, the controller 180 may obtain information on the intensity of the external magnetic field.

For example, the information detector 540 can acquire information on the intensity of the external magnetic field generated by the magnetic field generator 400 based on the magnitude of the current rectified by the rectifier 520. The magnitude of the alternating current induced in the coil 510 of the charger unit 200 may increase as the intensity of the external magnetic field generated by the magnetic field generator 400 increases, The magnitude of the direct current to be rectified and output may also increase in conjunction with the magnitude of the direct current.

Alternatively, the information detector 540 may detect the magnitude of the alternating current induced in the coil 510 of the charger 200 and may determine the magnitude of the detected alternating current as the magnitude of the detected alternating current, It may also be possible to detect information.

21, it is possible to supply an alternating current from the coil 510 of the charger 200 to the information detector 540. In this case,

That is, the relatively large intensity of the external magnetic field generated by the magnetic field generator 400 may mean that the magnitude of the alternating current induced in the coil 510 of the charger 200 is large, It may mean that the magnitude of the direct current to be rectified and output by the rectifying unit 520 is large.

For example, as in the case of Fig. 25, when the intensity of the magnetic field increases, the power can also increase. Accordingly, if the intensity of the external magnetic field is relatively large, the battery 270 can be charged at a high speed.

In the following description of FIG. 22, description of the same elements as those of FIG. 11 and / or FIG. 18 is omitted.

22, it is determined whether or not the current mode is the charging mode for charging the battery 270 (S2200). In the case of the charging mode, power is generated using the external magnetic field provided from the outside (S2210) Information on the strength of the external magnetic field can be obtained in the detecting unit 540 (S2220).

Here, the information detector 540 obtains information about the intensity of the external magnetic field (S2220). The information detector 540 obtains information about the magnitude of the DC current rectified by the rectifier 520, Or information on the magnitude of the alternating current output by the coil 510 from the information detecting unit 540 may be obtained. Hereinafter, the information detector 540 acquires information on the magnitude of the rectified current, or acquires information on the intensity of the magnetic field with respect to acquiring information on the magnitude of the alternating current. Therefore, the meaning of acquiring the information about the magnetic field strength may mean acquiring information about the magnitude of the direct current that is rectified by the rectifying unit 520 of the charging unit 200, It is possible to obtain information on the magnitude of the alternating current outputted by the coil 510 of the transformer.

After the magnetic field intensity information is acquired (S2220), it is judged whether or not the intensity of the magnetic field currently flowing has a strength suitable for fast charging (S2230).

As a result of the determination, if the intensity of the incoming magnetic field is not suitable for fast charging, the connected battery 270 can be charged (S2250) in the normal charging mode.

If the intensity of the incoming magnetic field is suitable for fast charging, the connected battery 270 may be charged (S2240) in the fast charging mode.

For example, when the intensity of the magnetic field generated by the magnetic field generator 400 is relatively weak as the first intensity A (Wb / m ² ) in the case of FIG. 23A, The magnitude of the direct current output from the inverter 520 may be relatively small as ccA as shown in FIG. 23 (C).

Whereas, the strength of the magnetic field which is a magnetic-field generating unit 400. In the case of (B) in Fig. 23 occurs first intensity (A (Wb / m ²⁾⁾ greater than the second intensity (B (Wb / m ²⁾ The magnitude of the direct current output from the rectifying section 520 of the charger 200 may be relatively large as ddA larger than ccA as shown in Fig. 23 (C).

23B and when the intensity of the magnetic field generated by the magnetic field generating section 400 is the second intensity B (Wb / m ² ), as compared with the case of FIG. 23A, It is possible to supply the battery 270 with a higher power (larger charging current) to make the charging speed of the battery 270 faster.

In other words, it is as follows.

The intensity of the external magnetic field, a first intensity (A (Wb / m ²⁾⁾ in case the power of the first as to the intensity of the external magnetic field, the first intensity power (A (Wb / m ²⁾ supplied to the battery 270 The first power and the second power may be different from each other when the power supplied to the battery 270 is a second power in a second intensity (B (Wb / m ² )) different from the second power (B (Wb / m ² ) Preferably, the second power may be greater than the first power if the second intensity B (Wb / m ² ) is greater than the first intensity A (Wb / m ² ).

(B (Wb / m ² )) in the case where the intensity of the magnetic field generated by the magnetic field generating section 400 is the first intensity (A (Wb / m ² ) The charging current and the charging voltage of the battery may be similar to those in the case of Fig. 15 described above.

In detail, when the magnetic field generated by the magnetic field generator 400 has a first intensity (A (Wb / m ² )), when the first battery 270A having the maximum allowable current MaxA is mounted to be matched, and if the strength of the magnetic field that the magnetic-field generating unit 400 generate the first intensity (a (Wb / m ²⁾⁾ greater than the second intensity (B (Wb / m ²⁾⁾ is the maximum allowable It is possible to cope with the case where the second battery 270B whose current MaxA is larger than aA is mounted.

The magnitude of the electric power supplied to the battery 270 when the intensity of the magnetic field generated by the magnetic field generator 400 is the second intensity B (Wb / m ² ) is larger than the magnitude of the magnetic field generated by the magnetic field generator 400 It may be preferable that N (N is a natural number equal to or greater than 2) times the magnitude of the power supplied to the battery 270 when the intensity is the first intensity (A (Wb / m ² )).

On the other hand, when the intensity of the applied magnetic field is greater than a preset threshold value, it is possible to increase the magnitude of the electric power supplied to the battery 270, for example, the charging current to rapidly charge the battery 270. The following is a look at this. In the following Fig. 24, description of the same elements as those of Figs. 11, 18 and 22 is omitted.

Referring to FIG. 24, it is determined whether or not the current mode is the charging mode for charging the battery 270 (S2400). In the charging mode, power is generated using the external magnetic field provided from the outside (S2410) Information on the intensity of the external magnetic field introduced from the detector 540 can be obtained (S2420).

After the information on the strength of the magnetic field is acquired (S2420), it can be determined whether or not the intensity of the external magnetic field is equal to or greater than a predetermined threshold value (S2430).

Alternatively, information on the magnitude of the current derived from the external magnetic field, that is, the magnitude of the induced current, may be obtained, and it may be possible to determine whether the magnitude of the induced current is equal to or greater than a preset threshold value. Here, the induced current may be an AC current output from the coil 510 of the charger 200 or a DC current rectified and rectified by the rectifier 520 of the charger 200.

As a result of the determination, if the intensity of the external magnetic field is smaller than the threshold value (or if the induced current is smaller than the predetermined threshold value), the first power is supplied to the battery 270 to charge the battery 270 at the first speed Chungcheon, S2450).

Alternatively, if the intensity of the external magnetic field is greater than the threshold value (or if the induced current is greater than a preset threshold value), a second power greater than the first power is supplied to the battery 270, It is possible to charge the battery 270 at a high speed (S2440).

For example, as in the case of FIG. 26A, when the magnetic field generating unit 400 is generated and the intensity of the magnetic field flowing into the charger 200 is greater than a preset threshold value ThV, It is possible to charge the battery 270 in the normal charging mode when the intensity of the magnetic field is smaller than the threshold value ThV.

26B, when the intensity of the induction current generated by the magnetic field generating unit 400 and flowing into the charger 200 is greater than a preset threshold value ThC, the battery 270 It is possible to charge the battery 270 in the normal charging mode when the charging is performed in the fast charging mode and the intensity of the induced current is smaller than the threshold value ThC.

27A, when the intensity of the magnetic field is smaller than the first threshold ThV1, the first power (or the first current) is supplied to the battery 270, And can be charged at the first speed.

(Or a second current larger than the first current) larger than the first power is supplied to the battery 270 when the magnitude of the magnetic field is greater than the first threshold ThV1 and smaller than the second threshold ThV2 So that the battery 270 can be charged at a second speed higher than the first speed.

(Or a third current larger than the second current) larger than the second power is supplied to the battery 270 when the magnitude of the magnetic field is greater than the second threshold value ThV2 and smaller than the third threshold value ThV3 So that the battery 270 can be charged at a third speed higher than the second speed.

(Or a fourth current larger than the third current) larger than the third power to the battery 270 and supplies the battery 270 to the third speed (or the second speed) when the intensity of the magnetic field is greater than the third threshold value ThV3. It is possible to charge at a faster fourth speed.

Alternatively, when the intensity of the induced current induced by the magnetic field is smaller than the first threshold value ThC1 as in the case of FIG. 27 (B), the first power (or the first current) is supplied to the battery 270 So that the battery 270 can be charged at the first speed.

(Or a second current larger than the first current) greater than the first power is supplied to the battery 270 when the intensity of the induced current is greater than the first threshold ThC1 and smaller than the second threshold ThC2 And the battery 270 can be charged at a second rate faster than the first rate.

(Or a third current larger than the second current) greater than the second power is supplied to the battery 270 when the intensity of the induced current is greater than the second threshold ThC2 and smaller than the third threshold ThC3 So that the battery 270 can be charged at a third rate faster than the second rate.

(Or a fourth current larger than the third current) larger than the third power to the battery 270 when the intensity of the induced current is greater than the third threshold value ThC3, It is possible to charge the battery at a fourth speed faster than the speed.

27 shows only the case where the threshold value for the intensity of the magnetic field and the threshold value for the intensity of the induced current are divided into three stages in total. However, the threshold value for the intensity of the magnetic field and / May be varied in various ways.

In the mobile communication terminal according to the present invention, it is possible to select whether the battery is to be charged at a high speed or in a normal state by considering the type of the battery and the intensity of the magnetic field (the intensity of the induced current). The following is a look at this. In the following Fig. 28, description of the same contents as those of Figs. 11, 18, 22, and 24 is omitted.

28, it is determined whether the current mode is the charging mode for charging the battery 270 (S2600). In the case of the charging mode, power is generated using the external magnetic field provided from the outside (S2610) Information on the intensity of the external magnetic field flowing in the detecting unit 540 and information on the connected battery 270 can be obtained (S2620).

After the information on the battery 270 and the information on the strength of the magnetic field are acquired (S2620), it can be determined whether the connected battery is a fast rechargeable battery (S2630).

Although not shown, it is also possible to determine whether or not the maximum allowable current of the currently connected battery is equal to or greater than a preset threshold current. This has been described in detail in FIG.

If it is determined that the currently connected battery is a fast rechargeable battery, it may be determined whether the strength of the magnetic field is strong enough to enable fast charging (S2640).

Alternatively, although not shown, it may be possible to determine whether the intensity of the magnetic field (or the intensity of the induced current) is equal to or greater than a preset threshold value. This is described in detail in FIG.

28, it is judged whether or not the intensity of the magnetic field is strong enough (S2640) after judging whether the connected battery is a fast-charge battery (S2630). However, it is judged whether or not the intensity of the magnetic field is sufficiently strong It is possible to determine whether the connected battery is a high-speed rechargeable battery (S2630).

If it is determined in step S2640 that the intensity of the magnetic field is strong enough to enable fast charging, the battery 270 may be charged in the fast charging mode (S2650).

On the other hand, if it is determined in step S2630 that the connected battery 270 is a general rechargeable battery, or if it is determined in step S2640 that the strength of the magnetic field is not strong enough to enable fast recharging, (S2660).

In other words, it is as follows.

When the maximum allowable current of the battery 270 is less than a preset threshold current or when the magnetic field strength is less than a preset threshold value, the battery 270 is charged at a first rate, And charging the battery at a second rate faster than the first rate if the magnitude of the external magnetic field is greater than the threshold value.

Alternatively, the maximum available current (MaxA) is aA of the first battery (270A) is mounted on the mobile terminal 100, the magnetic field generation part 400, the intensity of the magnetic field that occurs, the first intensity (A (Wb / m ² ), A first battery 270A having a maximum allowable current (MaxA) of aA is installed in the mobile communication terminal 100, and the first battery 270A having a maximum allowable current (MaxA) The electric power supplied to the first battery 270A in the case where the intensity of the magnetic field generated by the second battery 400 is a second intensity A (Wb / m ² ) different from the first intensity A (Wb / m ² ) A second battery 270B having a maximum allowable current MaxA different from aA of the first battery 270A is mounted on the mobile communication terminal 100 and a magnetic field generated by the magnetic field generator 400 is generated The electric power supplied to the first battery 270A in the case where the magnetic field strength is the first intensity A (Wb / m ² ) is referred to as a third electric power and the electric power supplied to the second battery 270B ) Is mounted on the mobile terminal 100, the magnetic field generation part 400, the intensity of the magnetic field that is generated the second electric power supplied to the first battery (270A) in the case of the 2nd century (B (Wb / m ²⁾⁾ 4 Let's assume power.

In this case, at least one of the first power, the second power, the third power, and the fourth power may be different from at least one of the others.

In addition, the second battery (270B) a maximum allowable current (MaxA) of bA is the larger, the second intensity than the first maximum allowable current (MaxA) of the battery (270A) aA (B (Wb / m 2)) of the (A (Wb / m < ² >)), the fourth power may be larger than the first power, the second power and the third power. In addition, the first, second, and third powers can be the same.

For example, as in the case of FIG. 29, when the battery 270 is a high-speed type battery, the battery is charged in the fast-charge mode when the intensity of the magnetic field is strong enough for fast charging, It may be possible to charge in the normal charging mode.

Alternatively, the maximum allowable current (MaxA) bA of the second battery 270B is greater than a predetermined threshold current, and the maximum allowable current (MaxA) aA of the first battery 270A is greater than the threshold current Assuming that the second intensity B (Wb / m ² ) is smaller than the predetermined threshold value and the first intensity A (Wb / m ² ) is smaller than the threshold value, The fourth power may be greater than the first power, the second power and the third power. In addition, the first, second, and third powers can be the same.

Alternatively, when the intensity of the magnetic field generated by the magnetic field generator 400 is not large enough to enable fast charging, the charging unit 200 may increase the intensity of the magnetic field to the magnetic field generator 400 under the control of the controller 180 You can make a request to do so. Referring to FIGS. 16 and 30, the following will be described. In order to request the magnetic field generator 400 to increase the strength of the magnetic field in the charger 200 or the controller 180, the charger 200 includes a communication unit 550, The communication unit 400 may also include a communication unit 460. In Fig. 30 below, description of the same elements as those in Figs. 11, 18, 22, 24, or 28 is omitted.

Referring to FIG. 30, it is determined whether or not the current mode is the charging mode for charging the battery 270 (S2600). In the case of the charging mode, power is generated using the external magnetic field provided from the outside (S2610) Information on the intensity of the external magnetic field flowing in the detecting unit 540 and information on the connected battery 270 can be obtained (S2620).

After the information on the battery 270 and the information on the strength of the magnetic field are acquired (S2620), it can be determined whether the connected battery is a fast rechargeable battery (S2630).

If it is determined that the currently connected battery is a fast rechargeable battery, it may be determined whether the strength of the magnetic field is strong enough to enable fast charging (S2640).

As a result of the determination, if the intensity of the magnetic field is strong enough to allow fast charging, the battery 270 can be charged (S2650) in the fast charging mode.

On the other hand, if it is determined in step S2630 that the connected battery 270 is a general rechargeable battery, the battery 270 may be charged in the normal recharge mode (S2660).

If it is determined in step S2640 that the intensity of the magnetic field is not strong enough to allow fast charging, the communication unit 550 of the charging unit 200 may increase the strength of the magnetic field by the communication unit 460 of the magnetic field generating unit 400 Request (S3000).

The control unit 450 of the magnetic field generating unit 400 may control the output of the high frequency pulses by controlling the high frequency generating unit 410 based on the increase request received through the communication unit 460. Specifically, the high frequency generating unit 410 of the magnetic field generating unit 400 modulates (Pulse Width Modulation) the width of the high frequency pulses to be output under the control of the controller 450, or modulates (Pulse Frequency Modulation) Alternatively, the number of pulses can be modulated (Pulse Number Modulation) or the amplitude of pulses can be modulated (Pulse Amplitude Modulation). For example, the high frequency generating unit 410 of the magnetic field generating unit 400 can increase the frequency of the high frequency pulses to be output under the control of the controller 450. In this case, the power of the AC signal (high-frequency pulse) output by the high-frequency generating unit 410 may increase, and accordingly, the intensity of the magnetic field generated by the coil 420 of the magnetic- As shown in FIG.

After the request for increasing the magnetic field strength (S3000), it is possible to judge again whether or not the intensity of the magnetic field is strong enough to enable fast charging (S3010).

As a result of the determination, if the intensity of the magnetic field is strong enough to allow fast charging, the battery 270 can be charged (S2650) in the fast charging mode.

Meanwhile, in the mobile communication terminal 100 according to the present invention, information on charging of the battery 270 can be displayed on the display unit 151. [ The following is a look at this. Hereinafter, the description of the parts described in detail above will be omitted.

Referring to FIG. 32, the display unit 151 of the mobile communication terminal 100 may include a first screen area AR1 and a second screen area AR2. Here, the first screen area AR1 and the second screen area AR2 may be physically one but logically divided screens. In this example, only the case where the first and second screen areas AR1 and AR2 are logically divided is shown and described. Alternatively, as in the case of FIG. 5, the first and second screen areas AR1 and AR2 are physically divided May be possible.

Various information such as a background screen and call information can be displayed in the first screen area AR1 of the display unit 151 and radio wave reception sensitivity, time information, battery mark BM, etc. can be displayed in the second screen area AR2 Can be displayed. Here, although only the case where the battery mark BM is displayed in the second screen area AR2 of the display unit 151 is shown, the battery mark BM may be displayed in the first screen area AR1 have.

The mobile communication terminal 100 according to the present invention can display information on the charging of the battery using the battery mark BM.

For example, when the first battery 270A (general rechargeable battery) having the maximum allowable current MaxA is mounted to the mobile communication terminal 100 as in the case of FIG. 33A, The first battery mark BM1 may be displayed on the display unit 151 as in the case of FIG.

33 (B), when the second battery 270B (fast rechargeable battery) having the maximum allowable current MaxA larger than aA is mounted to the mobile communication terminal 100, The second battery mark BM2 different from the first battery mark BM1 can be displayed on the display unit 151 as in the case of the first battery mark BM.

The second battery mark BM2 may further include a lightning indication as compared to the first battery mark BM1 and the second battery mark BM2 may indicate that the currently mounted battery is a fast rechargeable battery. Accordingly, the user can easily confirm that the fast rechargeable battery is attached to the current mobile communication terminal 100 by checking the second battery mark BM2 displayed on the display unit 151. [

In addition, the second battery mark BM2 allows the user to intuitively / visually easily confirm that the charging speed of the second battery 270B is faster than the charging speed of the first battery 270A .

It is also possible that the second battery mark BM2 is used in the charging mode.

For example, when the second battery 270B, which is a fast rechargeable battery, is mounted on the mobile communication terminal 100 and the second battery 270B is being charged, the second battery mark BM2 is displayed on the display unit 151 Can be displayed.

In this case, the user can easily confirm whether the current charging mode is the fast charging mode or the normal charging mode.

Alternatively, as in the case of FIG. 34 (A), the first battery mark BM1 corresponding to the regular rechargeable battery may have a substantially perpendicular standing shape. In other words, the first battery mark BM1 can be arranged to have an angle of? 1 with respect to the interface between the first screen area AR1 and the second screen area AR2.

On the other hand, as in the case of FIG. 34 (B), the second battery mark BM2 corresponding to the fast recharging battery can have an inclined shape. In other words, the second battery mark BM2 can be inclined to have an angle of? 2 with respect to the interface between the first screen area AR1 and the second screen area AR2.

Even in this case, the user can easily confirm whether the currently installed battery is a quick-charge battery or a normal rechargeable battery, or easily confirm whether the current recharge mode is the fast recharge mode or the normal recharge mode.

Alternatively, as in the case of FIG. 35A, the first battery mark BM1 corresponding to the normal rechargeable battery is displayed relatively blurred, and the second battery mark BM2 corresponding to the fast rechargeable battery is displayed by the first battery Can be displayed relatively dark compared to the mark BM2.

35B, the first battery mark BM1 corresponding to the normal rechargeable battery is relatively small, and the second battery mark BM2 corresponding to the fast rechargeable battery is relatively small, BM2). ≪ / RTI > For example, the vertical height L2 of the second battery mark BM2 may be larger than the vertical height L1 of the first battery mark BM1.

It is possible to display not only the battery mark BM but also the battery capacity mark CVM on the display unit 151 of the mobile communication terminal 100 as in the case of FIG.

For example, when the regular rechargeable battery is installed in the mobile communication terminal 100, it is possible to display the first battery capacity mark CVM1 together with the first battery mark BM1. On the other hand, when the fast-charging battery is mounted on the mobile communication terminal 100, it is possible to display the second battery capacity mark CVM2 together with the second battery mark BM1. Here, the second battery capacity mark CVM2 may indicate that the capacity of the battery is larger or the charging speed is faster than the first battery capacity mark CVM1. To this end, the first battery capacity mark CVM1 may be a combination of a multiplication sign X and a number 1, and the second battery capacity mark CVM2 may be a combination of a multiplication sign X and a number 3. [ In such a case, the user may be able to recognize that the currently mounted battery is a triple speed fast rechargeable battery by recognizing the second battery capacity mark CVM2, or it may be possible to recognize that the current recharge mode is the triple speed fast recharge mode.

36, a magnetic field mark (MFM) indicating the strength information of the magnetic field may be displayed on the display unit 151 of the mobile communication terminal 100. [

This magnetic field mark MFM may be displayed adjacent to the battery mark BM in the second screen area AR2 of the display unit 151. [ Although not shown, the magnetic field mark MFM may be displayed in the first screen area AR1 of the display unit 151. [

For example, as in the case of FIG. 37 (A), the first magnetic field mark MFM1 corresponding to the normal charging mode is relatively small and the magnetic field intensity is sufficiently strong so that the fast charging mode The corresponding second magnetic field mark MFM2 may be relatively large compared to the first magnetic field mark MFM2. For example, the vertical height L3 of the second magnetic field mark MFM2 may be larger than the vertical height L4 of the first magnetic field mark MFM1.

37B, it is possible to display not only the magnetic field mark MFM but also the magnetic field strength mark MFSM on the display unit 151 of the mobile communication terminal 100. [

For example, when the magnetic field of the first intensity corresponding to the normal charging mode is transmitted to the mobile communication terminal 100, it is possible to display the first magnetic field strength mark MFSM1 together with the first magnetic field mark MFM1 . On the other hand, when the magnetic field corresponding to the fast charging mode is transmitted to the mobile communication terminal 100, the second magnetic field strength mark MFS2 together with the second magnetic field mark MFM1 It is possible to display it. Here, the second magnetic field strength mark MFSM2 can visually indicate that the intensity of the magnetic field is larger than that of the first magnetic field strength mark MFSM1.

When the information on the strength of the magnetic field is displayed on the display unit 151, the user confirms the second magnetic field mark MFM2 displayed on the display unit 151, It can be easily confirmed that the intensity is strong enough to be suitable for high-speed charging.

The shapes of the magnetic field mark (MFM) and the magnetic field strength mark (MFSM) can be variously changed.

For example, as in the case of FIG. 37C, when a magnetic field of the first intensity corresponding to the normal charging mode is transmitted to the mobile communication terminal 100, a combination of the multiplication symbol X and the number 1 The third magnetic field strength mark MFSM3 is displayed on the display unit 151. When the magnetic field of the second century stronger than the first intensity is transmitted to the mobile communication terminal 100, the multiplication sign X It is possible to display the fourth magnetic field strength mark MFSM4 having the combination of the number 2 and the number 2 on the display unit 151. [ In this case, the user recognizes the fourth magnetic field strength mark MFSM4 to indicate that the magnetic field generator 400 generates the magnetic field and the intensity of the magnetic field transmitted to the mobile communication terminal 100 is strong enough It may be possible to recognize it intuitively.

Referring to FIG. 38, the mobile communication terminal 100 according to the present invention can display at least one of the information on the charging mode, the estimated charging time information, and the charging rate information on the display unit 151 in the charging mode.

For example, as in the case of FIG. 38 (A), information on the charging mode (normal mode) and information on the estimated charging time in the first screen area AR1 of the display unit 151 in the normal charging mode (2 hours) can be displayed together. In this case, it is possible to display the first battery mark BM1 and the first magnetic field mark MFM1 corresponding to the normal charging mode in the second screen area AR2 of the display unit 151. [

On the other hand, as in the case of FIG. 38 (B), in the fast charging mode, the information on the charging mode (fast mode) and the information on the charging speed 2 (2) are stored in the first screen area AR1 of the display unit 151 Speed) and information on the estimated charging time (one hour) can be displayed together. In this case, it is possible to display the second battery mark BM2 and the second magnetic field mark MFM2 corresponding to the fast charge mode in the second screen area AR2 of the display unit 151. [

Alternatively, as in the case of FIG. 39, the mobile communication terminal 100 according to the present invention may display information on the charging mode, the estimated charging time information, and the charging rate information on the display unit 151 in the charging mode, Information on the battery, and information on the strength of the magnetic field.

For example, as in the case of FIG. 39 (A), in the normal charging mode, information on the charging mode (normal mode) and information on the expected charging time are stored in the first screen area AR1 of the display unit 151 (3 times), information on the charging speed (1X), information on the charging end time (17:00), information on the battery (X1) and information on the magnetic field strength (X1) .

On the other hand, in the fast charging mode, information on the charging mode (fast mode) and information on the estimated charging time (e.g., It is possible to display the information on the charging speed (3 times), information on the charging end time (15:00), information on the battery (X3) and information on the magnetic field intensity (X4).

Here, the information on the battery includes information on whether the battery is a general rechargeable battery or a fast rechargeable battery, and also how fast the rechargeable battery can be charged (how many times faster can be charged) It is possible to include the information on the information.

In addition, when the battery speed information and the magnetic field strength information are different, the charging speed of the battery may be determined according to the smaller of the battery speed information and the magnetic field strength information.

If the battery is charged at 3x speed (X3) and the battery is charged at 4x speed depending on the magnetic field strength, it is possible that the power supplied to the battery (current) reaches a level at which the 3x battery can not withstand There is a possibility that the battery may be damaged.

39B, if the battery is a battery capable of high-speed charging at triple speed (X3), and the magnetic field strength is such that the battery is capable of fast charging at quadruple speed (X4), the charging speed of the battery is 3 times speed.

Alternatively, it is possible to display various information on the battery charging on the display unit 151 in the form of a pop-up window.

For example, in a state of displaying a predetermined image 3900 in the first screen area AR1 of the display unit 151 as in the case of Figs. 40 (A) and 40 (B) A popup window PUW for displaying various battery charging information is displayed in the first screen area AR1 of the display unit 151 and various information about the charging of the battery in the popup window PUW Can be displayed. In FIG. 40, the information on the charging of the battery can be sufficiently deduced from the contents of FIG. 39 above.

41, it is possible to display a popup window PUW in the first screen area AR1 of the display unit 151 and to display graphic information on the charging speed in the popup window PUW . In FIG. 41, the graphic information on the charging speed displayed in the pop-up window PUW can be sufficiently inferred from FIG.

Alternatively, the information about the charging of the battery displayed on the display unit 151 may include a menu for selecting the charging speed of the battery.

For example, as in the case of FIG. 42, a general selection menu 4100 for selecting a general charging mode and a high-speed selection menu 4100 for selecting a fast charging mode are displayed in the first screen area AR1 of the display unit 151 4110). In this case, the user can select any one of the general selection menu 4100 and the high-speed selection menu 4110 displayed on the display unit 151.

If the mounted battery is a fast rechargeable battery and the intensity of the magnetic field generated by the magnetic field generator 400 is strong enough to be suitable for fast charging, The menu 4100 and the high-speed selection menu 4110 can be displayed together and the battery can be charged in the normal charging mode or the fast charging mode according to the user's selection.

On the other hand, in order to prevent the user from selecting the fast charge mode when the mounted battery is a general rechargeable battery or when the intensity of the magnetic field generated in the magnetic field generator 400 is not strong enough to be suitable for fast charge, It is possible not to display the high-speed selection menu 4110 on the display unit 151. [

43, a popup window PUW is displayed in the first screen area AR1 of the display unit 151 and a general selection menu 4100 for selecting a normal charging mode in the popup window PUW A fast selection menu 4110 for selecting the fast charge mode can be displayed.

Alternatively, as in the case of Fig. 44, it is possible to display a plurality of charging rate menus for selecting three or more charging rates on the display unit 151. [

In this case, it is possible for the user to variously select the charging speed of the battery at 1x speed (X1), 2x speed (X2), 3x speed (X3), or 4x speed (X4).

Alternatively, although not shown, it may be possible to display a plurality of charge rate menus for populating a predetermined pop-up window on the display unit 151 and selecting three or more charge rates on the pop-up window.

45 to 53 are diagrams for explaining a configuration and a driving method of a mobile communication terminal for wired charging. In the following wired charging method, the description of the parts overlapping with the wireless charging method described in detail above will be omitted.

Referring to FIG. 45, the charging terminal 4410 of the wire charger 4400 may be connected to the mobile communication terminal 100 according to the present invention. For example, the charging terminal 4410 of the wired charger 4400 may be connected to the interface unit 170 of the mobile communication terminal 100. Here, the charging terminal 4410 may be referred to as an interface portion of the wire charger 4400.

The wired charger 4400 is supplied with power from a commercial AC power source that supplies 110V, 220V, or the like, though not shown, to charge the battery 270 or convert the power into a form necessary for the operation of the mobile communication terminal 100 have. For example, the wired charger 4400 may receive AC power from a commercial AC power source and rectify it to a DC power source and output it.

The mobile communication terminal 100 is supplied with power from the wire charger 4400 through the interface unit 170 and can perform various functions such as display of images, data transmission and reception, and voice communication. In addition, the mobile communication terminal 100 may receive power from the wired charger 4400 through the interface unit 170 to charge the battery mounted in the mobile communication terminal 100.

The mobile communication terminal 100 according to the present invention may be configured such that the charging unit 200 is connected to the power supply unit 4510 and the information detection unit 4500 in order to charge the battery by receiving power from the wired battery charger 4400, . ≪ / RTI >

When the charging terminal 4410 of the wire charger 4400 is connected to the interface 170, the power supply unit 4510 controls the power inputted through the interface unit 170 to be supplied to the battery 270 ).

The information detecting unit 4500 can detect the information of the battery 270 under the control of the controller 180. [ Here, the kind of information of the battery 270 detected by the information detecting unit 4500, the detection method, and the like have been described in detail with reference to FIG. 12 and FIG.

The information detecting unit 4500 can detect information of the power inputted through the interface unit 170 under the control of the controller 180. [ Preferably, the information detector 4500 can detect size information of the power inputted through the interface unit 170, for example, current size information under the control of the controller 180. [

Also in the mobile communication terminal 100 having such a configuration, the charging rate of the battery 270 can be adjusted according to the information detected by the information detecting unit 4500. This will be described in more detail below. In the following FIG. 47, the description of the parts described in detail with reference to FIG. 11, for example, the method of acquiring the information of the battery 270, and the kind of information of the battery 270 are omitted.

It is determined whether or not the current mode is the charging mode for charging the battery 270 in step S4600. In the case of the charging mode, the power supply unit 4510 controls the interface unit 170 to generate power to be supplied to the battery 270 (S4610). Here, it is explained that the electric power supply unit 4510 generates electric power to be supplied to the battery 270 by the electric power received from the interface unit 170 after it is determined whether or not it is the charging mode. However, It is also possible to generate power to be supplied to the battery 270 by the power supply unit 4510 in response to the input of power through the interface unit 170. [ Alternatively, the power supply unit 4510 may supply the power transmitted from the interface unit 170 to the battery 270 when power is input through the interface unit 170, regardless of whether the charging mode is selected . Hereinafter, for convenience of description, it is assumed that power is supplied from the interface unit 170 to the battery 270 (S4610) after the charging mode is determined.

Then, the information detecting unit 4500 can acquire the information of the connected battery 270 (S4620).

After acquiring information on the battery 270 (S4620), it can be determined whether the currently connected battery 270 is a fast-charge battery (S4630).

As a result of the determination, if the currently connected battery 270 is a fast rechargeable battery, the battery 270 is charged at a high speed (S4640). If the currently connected battery 270 is not a fast rechargeable battery, (S4650).

If the currently connected battery 270 is a fast rechargeable battery, it is possible to charge the battery 270 at a high speed (S4640) by increasing the amount of power per hour supplied to the battery 270, have. On the other hand, when the currently connected battery 270 is not a fast rechargeable battery, the size of the electric power (current) supplied to the battery 270 is reduced to normally charge the battery 270 (S4650).

A method of charging the battery 270 in a normal manner and a method of charging the battery 270 in a fast manner have been described in detail above, and a detailed description thereof will be omitted.

The mobile communication terminal 100 adjusts the amount of electric power per unit time (the amount of current per unit time) supplied to the battery 270 according to the magnitude of the power input through the interface unit 170, It is possible to adjust the speed. This is described below. Hereinafter, the description of the portions described in detail above will be omitted.

48, it is determined whether the current mode is the charging mode for charging the battery 270 (S4600). In the case of the charging mode, the power supply unit 4510 controls the interface unit 170 to generate power to be supplied to the battery 270 (S4610).

Then, the information detecting unit 4500 can acquire the information of the power input through the interface unit 170, that is, the inflow power (S4720).

After the information of the inflow power is acquired (S4720), it is judged whether or not the currently inputted power is suitable for fast charging (S4730).

As a result of the determination, if the current incoming power is suitable for fast charging, the battery 270 is charged at a high speed (S4740). If the current incoming power is not suitable for fast charging, can do.

For example, assuming that the magnitude of the input power input from the interface unit 170 is the first power and the magnitude of the input power input from the interface unit 170 is the second power that is larger than the first power, Let's see. Here, a description will be made with reference to Fig.

In this case, as in the case of (A) of FIG. 15, when the magnitude of the inflow power is the second power, as compared with the case of the first power, the charging The current may be larger.

That is, when the magnitude of the inflow power is the second power, the magnitude of the current supplied to the battery 270 is increased. On the other hand, when the inflow power is the first power smaller than the second power, It is possible to reduce the magnitude of the current per unit time.

15B, assuming that the battery 270 is charged for a period from the time t0 to the time t1 when the magnitude of the inflow power is the second power, the charge current supplied to the battery 270 is it can be gradually decreased near the time t1.

As shown in FIG. 15B, when the magnitude of the inflow power is the second power, the charging voltage of the battery 270 may gradually increase to the maximum voltage Vmax during a period from the time t0 to the time t1.

In addition, maintaining Vmax after the charging voltage of the battery 270 rises to Vmax at time t1 may mean that charging of the battery 270 is completed at time t1.

On the other hand, when the magnitude of the input power is the first power, the magnitude of the input power is smaller than the magnitude of the input power. 270).

In addition, when the magnitude of the inflow power is the first power, the charge current supplied to the battery 270 may gradually decrease in the vicinity of the time point t2.

In addition, when the magnitude of the inflow power is the first power as shown in FIG. 15B, the charging voltage of the battery 270 may gradually increase to the maximum voltage Vmax during the period from the time t0 to the time t2 .

On the other hand, when the magnitude of the inflow power is larger than a preset threshold current, it is possible to increase the magnitude of the power supplied to the battery 270, for example, the charge current to charge the battery 270 at a high speed. The following is a look at this. Hereinafter, the same descriptions as those of FIGS. 19 and 20 will be omitted.

It is possible to judge whether or not the magnitude of the inflow power flowing from the interface section 170 is equal to or greater than a preset threshold value ThVa.

If the magnitude of the incoming power flowing from the interface unit 170 is smaller than the preset threshold value ThVa, the first power is supplied to the battery 270 to charge the battery 270 at the first speed Chungcheon).

Alternatively, when the magnitude of the incoming power flowing from the interface unit 170 is equal to or greater than a preset threshold value ThVa, the second power greater than the first power is supplied to the battery 270, It is possible to charge the battery 270 (fast charge).

The above contents can be sufficiently inferred through the foregoing FIG. 19.

Alternatively, the threshold may include first, second, and third thresholds (ThVa1, ThVa2, ThVa3).

In this case, when the magnitude of the inflow power flowing from the interface unit 170 is smaller than the first threshold ThVa1, the first power (or the first current) is supplied to the battery 270, You can charge at speed.

(Or a second current larger than the first current) larger than the first power when the magnitude of the incoming power flowing from the interface unit 170 is larger than the first threshold ThVa1 and smaller than the second threshold ThVa2, May be supplied to the battery 270 to charge the battery 270 at a second speed higher than the first speed.

(Or a third current larger than the second current) larger than the second power when the magnitude of the incoming power flowing from the interface unit 170 is larger than the second threshold ThVa2 and smaller than the third threshold ThVa3, May be supplied to the battery 270 to charge the battery 270 at a third speed higher than the second speed.

(Or a fourth current larger than the third current) larger than the third power is supplied to the battery 270 when the magnitude of the inflow power flowing from the interface unit 170 is greater than the third threshold ThVa2 So that the battery 270 can be charged at a fourth speed faster than the third speed.

Although only the case of dividing the threshold value ThVa into three stages is shown in the above, the number of threshold values can be variously changed.

The above contents can be sufficiently inferred through the foregoing FIG. 20.

In the mobile communication terminal according to the present invention, it is possible to select whether the battery is to be charged at a high speed or in a normal state by considering the type of the battery and the intensity of the incoming power. The following is a look at this. In the following FIG. 49, the same descriptions as those of FIGS. 28, 29, and 48 are omitted.

49, it is determined whether or not the current mode is the charging mode for charging the battery 270 (S2600). In the case of the charging mode, the inflow power flowing from the wired battery charger 4400 through the interface unit 170 is used The information detecting unit 540 obtains information on the intensity of the inflow power flowing from the interface unit 170 and information on the connected battery 270 in step S5210 )can do.

After the information on the battery 270 and information on the intensity of the inflow power are obtained (S5220), it can be determined whether the connected battery is a fast rechargeable battery (S5230).

Although not shown, it is also possible to determine whether or not the maximum allowable current of the currently connected battery is equal to or greater than a preset threshold current. This has been described in detail above.

As a result of the determination, if the currently connected battery is a fast rechargeable battery, it may be determined whether the intensity of the incoming power is strong enough to enable fast charging (S5240).

Alternatively, although not shown, it may be possible to determine whether the intensity of the incoming power (or the intensity of the incoming current) is equal to or greater than a preset threshold current. This has been described in detail above.

In FIG. 49, after determining whether the connected battery is a fast-charge battery (S5230), it is determined whether or not the intensity of the inflow power is sufficiently strong (S5240). Alternatively, it is determined whether or not the inflow power is sufficiently strong (S5240), it may be possible to determine whether the connected battery is a fast-charge battery (S5230).

As a result of the determination in step S5240, if the intensity of the inflowing power is strong enough to enable fast charging, the battery 270 can be charged in the fast charging mode (S5250).

On the other hand, if it is determined in step S5230 that the connected battery 270 is a general rechargeable battery, or if it is determined in step S5240 that the intensity of the inflow power is not strong enough to enable fast charging, Mode (S5260).

In other words, it is as follows.

When the maximum allowable current of the battery 270 is less than a preset threshold current or the intensity of the incoming power is less than a predetermined threshold value, the battery 270 is charged at a first rate, and the maximum allowable current of the battery 270 It can be seen that the battery is charged at a second rate higher than the first rate if it is larger than the threshold current and the intensity of the input power is greater than the threshold value.

Or when the first battery 270A having the maximum allowable current MaxA is mounted on the mobile communication terminal 100 and the intensity of the inflow power flowing from the interface unit 170 is the first intensity, The first battery 270A having the maximum allowable current MaxA is connected to the mobile communication terminal 100 and the power supplied to the interface unit 170 And the maximum allowable current (MaxA) is bA different from the aA of the first battery 270A, the second battery 270A is referred to as a second battery, The power supplied to the first battery 270A in the case where the battery 270B is mounted on the mobile communication terminal 100 and the intensity of the inflow power flowing from the interface unit 170 is the first intensity is referred to as a third power, The second battery 270B having the maximum allowable current MaxA is connected to the mobile communication terminal 100 Let be assumed as the fourth power of the power supplied to the first battery (270A) in the case where the intensity of the incoming power that flows from the interface section 170 of the second intensity.

In this case, at least one of the first power, the second power, the third power, and the fourth power may be different from at least one of the others.

If the maximum allowable current (MaxA) bA of the second battery 270B is larger than aA, which is the maximum allowable current (MaxA) of the first battery 270A, and the second intensity is greater than the first intensity, 4 power may be greater than the first power, the second power, and the third power. In addition, the first, second, and third powers can be the same.

Alternatively, if bA, which is the maximum allowable current (MaxA) of the second battery 270B, is greater than a predetermined threshold current, aA, which is the maximum allowable current (MaxA) of the first battery 270A, is smaller than the threshold current, If the intensity is greater than a predetermined threshold and the first intensity is less than the threshold value, then the fourth power may be preferred to be greater than the first power, the second power and the third power. In addition, the first, second, and third powers can be the same.

For example, if the battery 270 is a high-speed type battery and the battery is of a high-speed type that is strong enough so that the intensity of the incoming power is suitable for high-speed charging, Lt; / RTI >

If the intensity of the incoming electric power flowing from the wired battery charger 4400 through the interface unit 170 is not large enough to enable fast charging, the charging unit 200 can control the wired battery charger 4400, under the control of the controller 180, To increase the intensity of the incoming power. This will be described with reference to FIG. 50 attached hereto.

In order to request the charging unit 200 or the control unit 180 to increase the intensity of the incoming electric power to the wire charging unit 4400, the charging unit 200 may preferably include the communication unit 550 have. In addition, although not shown, the wired charger 4400 may also include a communication unit for receiving a request for strength of the incoming power from the communication unit 550 of the charging unit 200. In the following FIG. 50, the description of the duplicated description is omitted, as it is the same as FIG. 30 or FIG. 49 described above.

50, it is determined whether the current mode is the charging mode for charging the battery 270 (S5200). If the mode is the charging mode, the input power flowing from the cable charger 4400 through the interface unit 170 (S5210) the power to be supplied to the battery 270, and information on the intensity of the inflow power flowing in from the information detector 540 and information on the connected battery 270 (S5220).

After the information on the battery 270 and information on the intensity of the inflow power are obtained (S5220), it can be determined whether the connected battery is a fast rechargeable battery (S5230).

As a result of the determination, if the currently connected battery is a fast rechargeable battery, it may be determined whether the intensity of the incoming power is strong enough to enable fast charging (S5240).

As a result of the determination, if the intensity of the incoming electric power is strong enough to allow fast charging, the battery 270 can be charged in the fast charging mode (S5250).

On the other hand, if it is determined in step S5230 that the connected battery 270 is a general rechargeable battery, the battery 270 may be charged in the normal recharge mode (S5260).

If it is determined in step S5240 that the intensity of the incoming electric power is not strong enough to enable fast charging, the communication unit 550 of the charging unit 200 requests the wired battery charger 4400 to increase the intensity of the incoming electric power )can do.

Then, the wired battery charger 4400 can increase the output power based on the increase request received from the charging unit 200. [

After the increase request of the inflow power (S5400), it can again be determined whether the intensity of the inflow power is strong enough to enable fast charging (S5410).

As a result of the determination, if the intensity of the incoming electric power is strong enough to allow fast charging, the battery 270 can be charged in the fast charging mode (S5250).

Meanwhile, in the mobile communication terminal 100 according to the present invention, information on charging of the battery 270 can be displayed on the display unit 151. [ The following is a look at this. Hereinafter, the description of the parts described in detail above, for example, the parts that are described in detail in FIGS. 32 to 35 and 38 to 44, will be omitted.

The display unit 151 of the mobile communication terminal 100 according to the present invention may display information on the battery 270 and information on charging. This has been described in detail in FIGS. 32 to 35 above.

51, the inflow power mark PM indicating the inflow power intensity information may be displayed on the display unit 151 of the mobile communication terminal 100. In this case,

This incoming power mark PM may be displayed adjacent to the battery mark BM in the second screen area AR2 of the display unit 151. [ The inflow power mark PM may be displayed in the first screen area AR1 of the display unit 151 although not shown.

For example, as in the case of FIG. 52 (A), since the intensity of the inflow power flowing from the wired charger 4400 through the interface unit 170 is relatively weak, the first inflow power mark PM1 can have a relatively small or shrunken shape and the second incoming power mark PM2 corresponding to the fast-charge mode is stronger than the first incoming power mark PM2, It is possible to have a shape which is as large as or as wide as the arm. The shape of the incoming power mark PM in the present invention may not be limited to those shown in Figs.

Referring to FIG. 53, the mobile communication terminal 100 according to the present invention can display at least one of the information on the charging mode, the estimated charging time information, and the charging rate information on the display unit 151 in the charging mode. In addition, it is possible to display at least one of information on the charging end time, information on the battery, and information on the intensity of the inflow power, on the display unit 151.

For example, as in the case of FIG. 53 (A), in the normal charging mode, information about the charging mode (normal mode) and information about the expected charging time in the first screen area AR1 of the display unit 151 (3 times), information on the charging speed (1X), information on the charging end time (17:00), information on the battery (X1) and information on the input power intensity (X1) have.

On the other hand, in the fast charging mode, information on the charging mode (fast mode) and information on the expected charging time (for example, It is possible to display the information X4 about the intensity of the incoming electric power and the information X3 about the battery (for example, 1 hour), information on the charging speed (3 times speed), information on the charging end time 15:00 have.

Here, the information on the battery includes information on whether the battery is a general rechargeable battery or a fast rechargeable battery, and also how fast the rechargeable battery can be charged (how many times faster can be charged) It is possible to include the information on the information.

If the battery speed information and the input power intensity information are different from each other, the charging speed of the battery may be determined according to the smaller of the battery speed information and the input power intensity information.

If the battery is 3 times faster (X3) and can be charged at high speed, if the charging speed of the battery is changed to 4 times according to the intensity of the incoming electric power, the power (current) supplied to the battery reaches a level And there is a possibility that the battery may be damaged.

53B, when the battery is a battery capable of high-speed charging at triple speed (X3) and the intensity of the incoming power has a strength capable of fast charging at four times speed (X4), the battery is charged The speed can be determined at triple speed.

Alternatively, it is possible to display various information on the battery charging on the display unit 151 in the form of a pop-up window. This has been described in detail in FIGS. 40 and 41. FIG.

Alternatively, the information about the charging of the battery displayed on the display unit 151 may include a menu for selecting the charging speed of the battery. This has been described in detail in Figs. 42 to 44 above.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.
