Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that, in the following examples and embodiments, features may be combined with each other without conflict.

In order to prolong the service life of the battery, the existing battery generally has a balancing function, and the meaning of battery balancing is to keep the single voltage of the lithium ion battery or the voltage deviation of the battery pack within an expected range, so that each single battery is kept in the same state in normal use, and the over-charge and over-discharge conditions are avoided. However, in the actual use process, the battery often cannot start the equalization function because the battery power is too low to reach the equalization condition, resulting in the final phenomenon of battery performance degradation.

As an example, in the field of drone technology, industrial drones and agricultural drones often discharge their batteries to a very low level to stop flying due to their special operational scenarios (survey, inspection, disaster relief, spraying, irrigation, etc.). The one-time flight time of the unmanned aerial vehicle is generally the single endurance time of the battery of the unmanned aerial vehicle, namely, under the use scenes of industrial unmanned aerial vehicles and agricultural unmanned aerial vehicles, the flyer generally controls the single operation time to be about to exhaust the battery capacity of the unmanned aerial vehicle. The inventor creatively finds that in the special application scenario, due to the fact that the operation is finished, the user may not immediately charge the battery of the unmanned aerial vehicle, but the battery is stored in a low-battery condition for a long time and is not used, and the battery is charged when the battery is needed. When the battery of the unmanned aerial vehicle is in a low power state, the battery equalization condition (generally, the battery capacity is greater than 10% and the voltage is higher than 3.69V) may not be achieved, so that the unmanned aerial vehicle battery cannot be equalized all the time. Such consequence leads to the pressure differential between the electric core of unmanned aerial vehicle battery bigger and bigger to make and lead to some electric core to charge the excessive pressure easily in the time of charging, cause electric core permanent damage, battery cycle performance is poor or the incident of battery.

Based on this, the embodiment of the application provides a battery maintenance method, an electronic device, a battery maintenance system and a computer readable storage medium. This application can confirm corresponding maintenance strategy according to the state information of battery, right through the maintenance strategy the battery maintains, makes the battery can reach the equilibrium condition and carry out the battery equilibrium to promote the life of battery, improve the security performance of battery.

The battery maintenance method is applied to the electronic equipment or the battery maintenance system, and the electronic equipment can be a charging device such as a charging box or a charger and can also be battery supply equipment such as mobile equipment. Wherein the mobile device includes at least a powered device and other portable mobile communication terminals, in one example, the mobile device includes but is not limited to an unmanned aerial vehicle, an unmanned ship, a mobile robot, a cradle head, a mobile phone, a computer, a Personal tablet, a Personal Digital Assistant (PDA), a wearable device, or the like. The electronic equipment or the battery maintenance system maintains the battery through the battery maintenance method, so that the service life of the battery is prolonged, and the safety performance of the battery is improved. The battery can be a battery formed by connecting a plurality of battery cells in series and/or in parallel, or a battery pack. The battery may be equipped with a communication device in communication with the electronic device and/or the battery maintenance system.

Referring to fig. 1, a schematic flow chart of a battery maintenance method according to an exemplary embodiment of the present application is shown, where the battery maintenance method may be applied to an electronic device, and the electronic device may be a charging device such as a charging box or a charger, and the charging device such as the charging box or the charger is used for charging and/or discharging the battery; the mobile device may be a battery-powered device such as a mobile device, and the battery is configured to be disposed on the mobile device to supply power to the mobile device. The method comprises the following steps:

in step S101, state information of the battery is acquired.

In step S102, determining a condition that the state information conforms to according to the state information, and obtaining a maintenance policy corresponding to the condition to maintain the battery; and the user operation authorities indicated by the maintenance strategies corresponding to different conditions are different.

In an embodiment, the battery includes a plurality of battery cells, and the inventor finds that, under the condition of a higher voltage, a difference between the battery cells is relatively small, and it is difficult to distinguish the quality of the battery, and under the condition of a low battery level, a voltage difference between the battery cells is more obvious and is also easy to detect.

It can be understood that, in the embodiment of the present application, no limitation is imposed on the specific value of the preset electric quantity, and the specific setting may be performed according to an actual application scenario. In addition, the detection opportunity of the electric quantity of the battery can be specifically set according to an actual application scene, for example, the electronic device can detect whether the electric quantity of the battery is lower than a preset electric quantity in real time, can detect whether the electric quantity of the battery is lower than the preset electric quantity periodically, and can detect whether the electric quantity of the battery is lower than the preset electric quantity under the condition that a preset condition (such as that the unmanned aerial vehicle stops flying or the movable device is in a use state) is met.

In an exemplary application scenario, due to the special operational scenario of a mobile device with a powered system (such as an unmanned aerial vehicle, a mobile robot, etc. for an exploration scenario), a user will often discharge the battery of the mobile device to a very low level before it is taken out of service, the battery capacity after use is generally in the capacity range of 2% -10% of the full capacity, for example, a preset capacity of 5% or 10% can be set, detecting whether the battery capacity is lower than a preset capacity after a user completes a job using the mobile device, and the state information of the battery is acquired under the condition that the electric quantity of the battery is lower than the preset electric quantity, and the subsequent maintenance step is carried out based on the state information, so that the method is more suitable for the use habit of a user, the battery maintenance is carried out after the mobile equipment is used, which is beneficial to prolonging the service life of the battery.

After the state information is acquired, the electronic device may determine, according to the state information of the battery, a condition that the state information meets, and then acquire a maintenance policy corresponding to the condition, so as to maintain the battery according to the maintenance policy; the state information includes, but is not limited to, cycle number of charging and discharging of the battery, a voltage difference between battery cells, or a duration of time during which a battery capacity is lower than a preset capacity value.

It should be noted that the user operation authority indicated by the maintenance policy corresponding to different conditions is different. In one example, the status information is a pressure difference between the battery cells, and the greater the pressure difference between the battery cells, the smaller the user operation authority indicated by the condition met by the pressure difference, that is, in the case that the voltage difference between the battery cells is small (the specific value can be specifically set according to the actual situation), the user operation authority indicated by the met condition may be that the user can select whether to perform the battery maintenance work, it may be determined that the battery maintenance work is to be performed or may be cancelled, and in the case where the pressure difference between the battery cells is large, the user operating right indicated by the condition met by the user operating right may be that the user must determine to perform battery maintenance work, namely, the battery can be used only after the battery is maintained, the safe use of the battery is ensured, and the service life of the battery is prolonged. In another example, the state information is the number of cycles of charging and discharging the battery, and the greater the number of cycles of charging and discharging the battery, the smaller the user operation authority indicated by the satisfied condition.

It can be understood that a plurality of conditions may be set according to an actual application scenario, each condition corresponds to a maintenance strategy, and the maintenance strategy for each condition is different.

In one exemplary embodiment, the battery includes a plurality of cells, and the status information includes a voltage difference between the battery cells; the conditions include at least the following two: the first condition is that the voltage difference between the battery cells is greater than a first preset value and less than a second preset value; wherein the second preset value is larger than the first preset value; the second condition is that the voltage difference between the battery cells is not less than the second preset value; and the user operation authority indicated by the first condition is greater than the user operation authority indicated by the second condition. Of course, the number of the battery cells included in the battery is not equal, and the specific values of the first preset value and the second preset value may be specifically set according to an actual application scenario, which is not limited in this embodiment of the application.

When the pressure difference meets the first condition, which indicates that the pressure difference is small although the pressure difference exists, and the influence on the use safety or the service life of the battery is small, the user operation authority indicated by the first condition correspondingly comprises: and determining to perform the maintenance work of the battery and canceling the maintenance work of the battery, namely, a user can select whether to perform the maintenance work of the battery according to actual needs.

Further, for the user operation authority indicated by the first condition, correspondingly, the electronic device may provide a first control indicating that the maintenance work on the battery is determined to be performed and a second control indicating that the maintenance work on the battery is cancelled; as one implementation manner, the electronic device includes a display, and the electronic device may display an interactive interface through the display, where the first control and the second control are displayed on the interactive interface; as another implementation manner, the electronic device may send information for generating the first control and the second control to a terminal device communicatively connected to the battery (or the electronic device), so as to display the first control and the second control on an interactive interface of the terminal device; the user can select the control to be triggered according to actual needs, namely, whether to perform maintenance work on the battery.

When the pressure difference meets the second condition, which indicates that the pressure difference is large at this time and may have a great influence on the use safety or the service life of the battery, the user operation authority indicated by the second condition accordingly includes: and determining to perform maintenance work on the battery, namely, in order to ensure the use safety and the service life of the battery, a user must perform the maintenance work on the battery.

Further, for the user operation authority indicated by the second condition, correspondingly, the electronic device may provide a first control indicating that the maintenance work of the battery is determined to be performed; as one implementation manner, the electronic device includes a display, and the electronic device may display an interactive interface through the display, where the first control is displayed on the interactive interface; as another implementation manner, the electronic device may send information for generating the first control to a terminal device in communication connection with the battery (or the electronic device), so as to display the first control on an interactive interface of the terminal device; that is, in order to ensure the safety and life of the battery, the user must perform maintenance work on the battery.

In another exemplary embodiment, the state information includes a number of cycles of charging and discharging the battery; the conditions include at least the following two: the first condition is that the cycle number of the charge and the discharge of the battery is more than a third preset value and less than a fourth preset value; wherein the fourth preset value is greater than the third preset value; the second condition is that the cycle number of the charge and the discharge of the battery is not less than the fourth preset value; and the user operation authority indicated by the first condition is greater than the user operation authority indicated by the second condition. Of course, specific values of the third preset value and the fourth preset value may be specifically set according to an actual application scenario, which is not limited in this embodiment.

When the number of battery charge and discharge cycles meets the first condition, it indicates that the number of battery charge and discharge cycles is small, and the influence on the use safety or the service life of the battery is small, and accordingly the user operation authority indicated by the first condition includes: and determining to perform the maintenance work of the battery and canceling the maintenance work of the battery, namely, a user can select whether to perform the maintenance work of the battery according to actual needs. When the number of battery charge/discharge cycles meets the second condition, which indicates that the number of battery charge/discharge cycles is large and may have a great influence on the use safety or the service life of the battery, the user operation right indicated by the second condition accordingly includes: and determining to perform maintenance work on the battery, namely, in order to ensure the use safety and the service life of the battery, a user must perform the maintenance work on the battery.

It should be understood that the above status information is only an example, and the number of cycles of charging and discharging the battery, the voltage difference between the battery cells, or the duration of the battery capacity being lower than the preset capacity value, which are included in the status information, may be arbitrarily combined and the corresponding condition may be determined, which is not limited in this embodiment of the present application.

In an embodiment, after obtaining a maintenance policy corresponding to a condition that the status information conforms, the electronic device may output a maintenance prompting message according to the maintenance policy, where the maintenance prompting message is used to prompt a user to perform a preparation for battery maintenance. As one implementation manner, the electronic device is provided with a display, and the maintenance prompt message can be displayed on the display; as another implementation manner, the electronic device may transmit the maintenance prompting message to a terminal device communicatively connected to the battery (or the electronic device), so as to display the maintenance prompting message on the terminal device. The embodiment prompts the user through the maintenance prompt information so as to enable the user to know the state of the battery, thereby carrying out corresponding battery maintenance work and improving the service life and the use safety of the battery.

Wherein, the maintenance prompting information of the maintenance strategies corresponding to different conditions is different. In one example, the state information is taken as the voltage difference between the battery cells and includes the two conditions as an example: the maintenance prompt information of the maintenance strategy corresponding to the first condition may be: "if the battery has a differential pressure, please confirm whether to perform maintenance", the maintenance prompt information of the maintenance strategy corresponding to the second condition may be: the battery pressure difference is too large, which affects the service life of the battery and requires maintenance. Therefore, the user is prompted through the maintenance prompt information, so that the user can know the state of the battery, and corresponding battery maintenance work is carried out.

Of course, the maintenance prompting messages of the maintenance strategies corresponding to different conditions may also be the same, and this is not limited in this embodiment of the present application.

In one embodiment, when a user determines to perform a maintenance operation on the battery, the electronic device may perform maintenance on the battery according to a corresponding maintenance policy in response to a user instruction. In one implementation, the battery may control the battery to stand for a first preset time at full charge; and controlling the battery to discharge until the residual electric quantity is lower than a specified value, and standing for a second preset time; and repeating the steps, wherein the repeated times are determined based on the conditions corresponding to the maintenance strategy. This embodiment is through right the battery is maintained, makes the battery can reach the equilibrium condition and carry out the battery equilibrium to promote the life of battery, improve the security performance of battery. The inventor finds that: for the battery used by the unmanned aerial vehicle, the service life of the battery without maintenance is ended after 90 times of charge and discharge cycles; the service life of the maintained battery is more than 90% after the charge and discharge cycles of 200 times, and obviously, the maintenance of the battery is beneficial to greatly prolonging the cycle service life of the battery.

It can be understood that, in the embodiment of the present application, no limitation is imposed on the first preset time, the second preset time, and the specific numerical value of the specified value, and the specific setting may be performed according to actual situations. In one example, the first preset time may be 24 hours, or more than 24 hours; the first preset time can be 6 hours or more than 6 hours; the specified value may be 20% of full charge.

In addition, the number of repetitions may be determined based on a condition corresponding to the maintenance strategy; in one example, the state information is a pressure difference between the battery cells, and the larger the pressure difference between the battery cells to which the condition is directed, the larger the corresponding repetition number, so as to implement deep maintenance on the battery.

When the electric quantity of the battery does not reach the full electric quantity, first prompt information can be output, and the first prompt information is used for prompting a user to carry out battery charging preparation work or prompting the user that the battery is ready to be charged; as one implementation manner, the electronic device is provided with a display, and the first prompt message can be displayed on the display; as another implementation manner, the electronic device may transmit the first prompt message to a terminal device communicatively connected to the battery (or the electronic device), so as to display the first prompt message on the terminal device. The embodiment prompts the user through the first prompt message so as to enable the user to know the battery maintenance progress.

When the amount of electricity of the battery has not reached the full amount of electricity, the battery may be charged by a charging device such as a charger or a charging box. The charging device such as the charger or the charging box can be connected with the battery in a communication way or in a hardware way and is used for charging the battery.

In one embodiment, the electronic device is a charger or a charging box, and considering that the current charger generally uses the CC/CV technology, the battery is charged with a CC constant current, and when the battery is saturated, the battery is float-charged with a CV constant voltage, so that the charger sets the CV voltage as the full-charge voltage Vmax of the battery. When the battery is at the lowest voltage-Vbat, the insertion of the charger momentarily presents a voltage difference of Vmax-Vbat, which results in a significant inrush current. If the battery is a 10-cell series, the voltage difference between the battery and the charger is (4.2V-3V) × 10 ═ 12V, the contact impedance between the two terminals is 50 milliohm, and the instant the charger is inserted into the battery, the surge current is 12V ÷ 50mR ═ 240A, which may cause interference in the communication line or breakdown of the charging MOS transistor. If the battery needs to be pulled out of the charger in the charging process, the battery is disconnected with the charger and then connected due to the shaking problem of manual operation, and the battery is pulled out after repeated times. In this process, when the battery is pulled out of the charger, the output voltage of the charger returns to Vmax, the ignition problem still occurs when the battery is reconnected, and negative voltage is caused to damage the communication control circuit of the charger and/or the battery.

Based on the above, when the battery is inserted into the charging interface of the charger or the charging box, the charging device such as the charger or the charging box acquires the real-time voltage of the battery through the charger or the charging box during the process of charging the battery, and determines the output voltage of the charging interface according to the real-time voltage and the gradient threshold value so as to charge the battery through the output voltage; repeating the above steps until the output voltage increases to the full charge voltage of the battery.

In this embodiment, when the battery is inserted into a charging interface of a charging device such as a charger or a charging box, the charger or the charging box detects a real-time voltage of the battery, and intelligently adjusts an output voltage of the charging interface according to the real-time voltage and a gradient threshold, so that the output voltage is gradually increased, the output voltage is ensured to be close to the real-time voltage, and soft start of a charging process is realized; meanwhile, when the battery is inserted into the charging interface of the charger or the charging box, the power output end of the charging interface has no voltage, so that the problems of surge current and ignition caused by high voltage difference at the moment when the battery is inserted into a charging device such as the charger or the charging box and the like are solved; in the charging process, the charging device can increase the output voltage at any time to be close to the real-time voltage of the battery, so that the real-time voltage of the battery is close to the output voltage of the charging device in the hot plugging process, and the ignition phenomenon can not be caused by hot plugging in and out in the charging process. Therefore, the effect that the battery of the movable equipment such as the unmanned aerial vehicle can be charged under lower electric quantity can be achieved, the use risk of the unmanned aerial vehicle when the battery is charged under low electric quantity is avoided, and the cost of a user is saved.

In the embodiment of the application, the gradient threshold is determined according to the maximum power of the battery, and is set so as to slowly increase the output voltage and ensure that the voltage difference between the charging interface of the charger or the charging box and the battery is always within a safe range, so that the phenomena of surge current and ignition cannot be generated when the battery is inserted into the charging interface; moreover, the battery is hot plugged in the charging process, so that the ignition phenomenon cannot be caused. The maximum power of the battery is used for determining the maximum value of the difference value between the output voltage and the real-time voltage when the battery is in a safe charging state, and the gradient threshold value is smaller than or equal to the maximum value. Optionally, the gradient threshold is equal to a maximum value, and the charging process of the battery can be realized at the fastest speed; optionally, the gradient threshold is less than a maximum value. It should be understood that the gradient threshold of the embodiment of the present application is greater than 0, and the output voltage is ensured to be gradually increased to charge the battery.

The gradient threshold value of the embodiment of the application can also be a preset value, that is, when the battery is charged, the gradient threshold value is a fixed and unchangeable value, such as 1V, and when the battery is charged, the maximum value of the difference value between the output voltage and the real-time voltage is 1V, so that when the battery is inserted into the charging interface, surge current and ignition phenomena cannot be generated, and in addition, the ignition phenomena cannot be caused by hot plug in and hot plug in the charging process; it should be understood that the gradient threshold may be other fixed and constant values. Of course, the gradient threshold may also be varied.

In some embodiments, the charging box is capable of adjusting the output voltage of the charging interface at preset time intervals according to the real-time voltage and the gradient threshold. The output voltage of the charging interface can be adjusted in real time or at intervals. By means of the mode of adjusting the output voltage of the charging interface, the effect of regulating the output voltage in a stepping mode can be achieved, and the phenomenon of power-on ignition is avoided. In some embodiments, when the charging box determines that the current real-time voltage is the sum of the last acquired real-time voltage and the gradient threshold, the output voltage of the charging interface is determined according to the current real-time voltage and the gradient threshold, and the most efficient charging process is ensured under the condition of ensuring safe charging.

In some embodiments, the charging box may obtain the real-time voltage of the battery according to a preset periodic frequency, that is, the charging box periodically obtains the real-time voltage. The magnitude of the periodic frequency can be set according to needs, for example, the charging box obtains the real-time voltage every 5 seconds. In certain embodiments, the charging box is non-periodically acquiring real-time voltage.

The strategy for determining the output voltage according to the real-time voltage and the gradient threshold value can be selected as required, for example, in some embodiments, the output voltage can be the sum of the real-time voltage and the gradient threshold value, and the strategy is simpler to implement; of course, other strategies for determining the output voltage based on the real-time voltage and the gradient threshold may be used. In other embodiments, the output voltage may be input from the outside.

In some embodiments, considering that a mobile device such as an unmanned aerial vehicle generally operates in an outdoor environment, when the battery power of the mobile device is insufficient, the battery needs to be charged in the current environment, and if the current environment is too low, the charging performance of the battery is affected; in this case, the charging device such as the charging box or the charger may further include a heating device, which may be a heating film, and the charging device such as the charging box or the charger may control the heating device to intermittently heat the battery according to an ambient temperature of an environment in which the battery is located during charging of the battery. This embodiment makes up because the low temperature environment that the battery was located causes battery self thermal loss through heating the battery intermittent type in charging device to battery charging process to guarantee that the self temperature of battery keeps invariable basically in charging process, can not interrupt the charging process of battery for the temperature of battery, guarantee that the battery is in the state that lasts to charge, improve the charge efficiency of battery, improve the life of battery.

In one implementation, the charging box is provided with a battery compartment, and when the battery accommodates the remaining battery compartment, the heating device is attached to the battery so as to heat the battery, so that the charging box can charge the battery at a preset temperature. The charging box can control the input current of the heating device, so that the heating device generates heat after being electrified. The charging box may control the magnitude of the current, and/or (and/or indicate either or both) the duty cycle of the energization, thereby adjusting the heating of the heating film. Further, before charging, the temperature of the battery itself may be set as an ambient temperature, and the charging box may adjust the magnitude of the current and/or the duty ratio of the energization according to the temperature of the battery, thereby adjusting the heat generation of the heating film. Wherein, the battery compartment can be provided with a temperature sensor for detecting the temperature of the battery. The charging box may also communicate with the battery to obtain temperature information of the battery.

In another embodiment, in addition to providing the heating device on the charging box or the charger, the heating device may be provided on the battery, and further, in the process of heating the battery by the charging box or the charger, the charging device such as the charging box or the charger may control the heating device to intermittently heat the battery according to the ambient temperature of the environment where the battery is located. This embodiment makes up because the low temperature environment that the battery was located causes the thermal loss of battery self through heating the battery intermittent type in charging device to the battery charging process to guarantee that the self temperature of battery keeps invariable basically in charging process, can not interrupt the charging process of battery for the temperature of battery, guarantee that the battery is in the state that lasts to charge, improve the charge efficiency of battery, improve the life of battery.

In an exemplary embodiment, during the process of charging the battery by a charging device such as a charging box or a charger, a duty ratio may be obtained according to an ambient temperature of the battery, where the duty ratio indicates that a heating device is controlled to intermittently heat the battery, and then the charging device controls the heating device to intermittently heat the battery according to the duty ratio. For example, a duty ratio of 0.5 may indicate that there is a time period of 0.5 seconds for the heating device to heat the battery every second, and the other 0.5 seconds for the heating device to not heat the battery.

Wherein, the larger the duty ratio is, the longer the duration of continuous heating in the process of intermittent heating of the battery by the heating device is. Taking an intermittent heating time period of 1 second as an example, for example, the duty ratio is 0.5, which means that the heating duration in each second is 0.5 second, and the heating device stops heating the battery for another 0.5 second; for example, the duty ratio is 0.2, which means that the heating duration is 0.2 seconds per second, and the heating device stops heating the battery for another 0.8 seconds. This also means that the larger the duty cycle, the more heat the battery gets during charging.

Wherein the duty cycle is inversely related to the ambient temperature. The lower the environmental temperature of the environment where the battery is located, the more heat loss of the battery is caused by the environment, so the duty ratio is larger, the more heat the battery can obtain through the heating device is, and the heat can be leveled with the lost heat as far as possible, so that the constant temperature of the battery is ensured.

In some embodiments, since the charging device does not start charging the battery when the charging device is connected to the battery, the temperature of the battery is not affected by heat generated during charging, the heating device does not start heating the battery electrically, and the temperature of the battery is not affected by heat generated by the heating device, the temperature of the battery is close to the ambient temperature of the environment where the battery is located, and therefore, the temperature of the battery when the charging device is connected to the battery can be determined as the ambient temperature.

In some embodiments, the charging device is further provided with an in-place detection device for detecting whether the battery is placed in place, so that the use risk is avoided.

In some embodiments, the charging device is provided with an alarm device.
