Background
In the prior art, when determining the battery capacity of an electronic device, the voltage value is usually used to look up a look-up table to find the capacity ratio. However, the comparison table is provided by the battery manufacturer when the battery leaves the factory, and is not adjusted according to different electronic devices. Since the relationship between voltage and electric quantity is not directly proportional, an error is liable to occur in data conversion. Especially, under the condition of low power of the electronic device, if the power display is incorrect, the user may mistakenly think that power is still available when the actual power of the battery is too low, which causes abnormal power failure in continuous use of the electronic device.
Therefore, it is necessary to invent a new power determination module and a power calibration method thereof to solve the drawbacks of the prior art.

The voltage detection module is used for detecting the real-time voltage value of the electronic device and obtaining the voltage value interval from the maximum use voltage value to the minimum use voltage value of the electronic device so as to divide the voltage value interval into a plurality of levels.

Detailed Description
To better understand the technical content of the present invention, preferred embodiments are specifically illustrated as follows.
Please refer to fig. 1, which is a system architecture diagram of the power determination module according to the present invention.
The power determining module 1 of the present invention is used for determining the power of a battery 3 installed in an electronic device 2 and calibrating the power display of the battery 3. The electronic device 2 may be a smart phone, a tablet computer, a notebook computer, etc., and the battery 3 may be a nickel-hydrogen battery, a lithium ion battery, etc., but the present invention is not limited to the above examples. The power determination module 1 may be disposed inside the electronic device 2 or disposed in an external storage device and then connected to the electronic device 2, and the factory production end 4 directly starts the power determination module 1 to correct the power of the battery 3 of the electronic device 2 by using OTA/FTP/WEB/TFTP or the like, but the invention is not limited to be started in this way.
The power determining module 1 includes a database 10, a voltage detecting module 20, a processing module 30 and a power displaying module 40. The database 10 is used to store the voltage-capacity comparison curve. The voltage-power comparison curve is provided by the manufacturer of the battery 3, and is a relationship between a maximum supply voltage to a minimum supply voltage and power consumption that the battery 3 can provide without considering the electronic device 2. The voltage detecting module 20 is used for detecting a real-time voltage of the electronic device 2 and obtaining the voltage value interval. The voltage value interval is an interval from a maximum voltage value to a minimum voltage value used by the electronic device 2, such as 240 volts of the maximum voltage value that the electronic device 2 can use, and the minimum voltage value is 110 volts, which is between 110 volts and 240 volts. Meanwhile, the voltage value interval may be divided into a plurality of levels, for example, 10 levels in average, that is, from 100%, 90%, 80%. to 0%.
The processing module 30 is electrically connected to the database 10 and the voltage detecting module 20, and is configured to query the voltage-power comparison curve, so as to actually correct the power ratios of the plurality of levels and the battery 3 among the voltage value zones of the electronic device 2 according to the voltage-power comparison curve. The processing module 30 creates a new voltage-to-power comparison table and stores the new table in the database 10 to replace the voltage-to-power comparison curve. That is, the processing module 30 queries the voltage-electric quantity comparison curve with the voltage value at 100% of the maximum use voltage value to know the electric quantity of the battery 3 at the maximum use voltage value. Next, the processing module 30 queries the voltage-electric quantity comparison curve for the voltage value at 90% of the maximum use voltage value to obtain the electric quantity of the battery 3 until the minimum use voltage value is queried. When the power of the corresponding battery 3 is known in all levels (10 levels in the embodiment) of the voltage range of the electronic device 2, the processing module 30 can establish a new voltage-power comparison table. Thus, the actual consumption relationship between the voltage and the power of the electronic device 2 can be established, rather than the consumption relationship between the voltage and the power of the battery 3.
In order to solve the difference between different types of electronic devices 2, the power determination module 1 may perform an actual lookup table according to the maximum voltage value to the minimum voltage value of the different electronic devices 2, so that each electronic device 2 establishes a "new voltage-power lookup table". Furthermore, even for the same kind of electronic devices 2, the maximum voltage value and the minimum voltage value of each electronic device 2 may have errors from the preset values. For example, when the predetermined maximum voltage is 3 volts, the actual measured maximum voltage may be 2.9 volts. If a new voltage-to-capacity comparison meter is directly used, synchronization deviation can occur. Therefore, the electric quantity determining module 1 can also measure the electronic device 2 by using the voltage detecting module 20 to obtain the actual maximum and minimum voltage values, and then correct the deviation error value. Thereby, errors on the electronic device 2 itself can be solved. It should be noted that, during the period of establishing the new voltage-to-electric quantity comparison table, the processing module 30 is to avoid the situation that the electronic device 2 may generate an instant high voltage, for example, an instant high energy consumption caused by the activation of the infrared PIR sensor or the continuous pressing of the button, so as to avoid the misjudgment.
Finally, the power display module 40 may be an application program software (App) installed in the electronic device 2. The power display module 40 queries the new voltage-power comparison table in the database 10 according to the real-time voltage value obtained by the voltage detection module 20, so as to accurately display the power of the battery 3 to the user. On the other hand, the voltage detection module 20 may read the voltage value in a normal state, that is, the real-time voltage value measured every ten times is used as a cycle, the real-time voltage value of the first time is used as a reference, and the error value generated by dividing the total error value generated by comparing the real-time voltage values of the other nine times with the real-time voltage value of the first time by the error value generated by the hierarchical times is used as the first voltage error adjustment value. Since there are many ways to adjust the error after finding the value measurement, the invention is not limited to what way to find the error adjustment value. In this way, the power display module 40 can display the power of the battery 3 more accurately.
On the other hand, after the power of the battery 3 can be accurately known, the processing module 30 can further set the power of the battery 3 to have a first low power and a second low power as the low power warning. When the processing module 30 knows that the power of the battery 3 is reduced to the first low power, the processing module 30 can control the LED of the electronic device 2 to flash and the speaker to sound. And when the power of the battery 3 is continuously reduced to a second low power, the processing module 30 controls only the low power consumption LED to flash. This two-stage alert can prevent excessive wear of the battery 3.
It should be noted that each module of the power determination module 1 may be configured by a hardware device, a software program combined with the hardware device, or a firmware combined with the hardware device. In addition, the present embodiment only illustrates the preferred embodiments of the present invention, and all possible combinations and modifications are not described in detail to avoid redundancy. However, one of ordinary skill in the art should appreciate that each of the above modules or elements is not necessarily required. And may include other existing modules or components in greater detail for practicing the invention. Each module or component may be omitted or modified as desired, and no other module or component may necessarily exist between any two modules.
Please refer to fig. 2, which is a flowchart illustrating a method for calibrating power according to the present invention. It should be noted that, although the method for correcting power according to the present invention is described below by taking the power determination module 1 as an example, the method for correcting power according to the present invention is not limited to the power determination module 1 with the same structure as described above.
The method for correcting the electric quantity of the invention firstly carries out step 201: detecting a voltage value interval from a maximum use voltage value to a minimum use voltage value of the electronic device.
First, the voltage detection module 20 detects a range from a maximum voltage value to a minimum voltage value, and sets the range as the voltage value range.
Then, step 202 is performed: the voltage value is divided into a plurality of levels.
The voltage value is divided into a plurality of levels, for example, 10 levels, but the invention is not limited thereto.
Then, step 203 is executed: and inquiring a voltage-electric quantity comparison curve.
The processing module 30 then queries the voltage-capacity comparison curve stored in the database 10.
And then step 204 is carried out: and actually correcting the plurality of levels among the voltage value intervals of the electronic device and the electric quantity ratio of the battery according to the voltage-electric quantity comparison curve.
The processing module 30 actually corrects the plurality of levels between the voltage value intervals of the electronic device 2 and the electric quantity ratio of the battery 3 according to the voltage-electric quantity comparison curve. That is, the processing module 30 uses each step (100%, 90%, 80% to 0%) between the maximum use voltage value and the minimum use voltage value to query the corresponding battery 3 for the charge.
Thus, step 205 is performed: and establishing a new voltage-electric quantity comparison table.
In this way, the processing module 30 can establish a new voltage-power comparison table according to the maximum voltage value to the minimum voltage value.
Finally, step 206 is performed: detecting a real-time voltage value of the electronic device, and inquiring the new voltage-electric quantity comparison table to display the electric quantity of the battery.
Finally, the power display module 40 queries the new voltage-power comparison table in the database 10 according to the real-time voltage value obtained by the voltage detection module 20, so as to accurately display the power of the battery 3 to the user.
The processing module 30 will establish a "new voltage-to-electric-quantity comparison table" for different types of electronic devices 2, and adjust the maximum and minimum operating voltage values of each electronic device 2 and the predetermined possible error, and finally avoid performing the calibration of the present invention when the electronic device 2 may generate an instant high voltage, so as to obtain a correct "new voltage-to-electric-quantity comparison table". It should be noted that the method for calibrating power of the present invention is not limited to the above-mentioned sequence of steps, and the sequence of steps can be changed as long as the objective of the present invention is achieved.
By means of the electric quantity correction method and the electric quantity judgment module 1, the electric quantity of the battery 3 can be accurately known, and damage to the computer system 2 is avoided.
It should be noted that the present embodiment only illustrates the preferred embodiments of the present invention, and all possible combinations of the variations are not described in detail for avoiding redundancy. However, one of ordinary skill in the art should appreciate that each of the above modules or elements is not necessarily required. And may include other existing modules or components in greater detail for practicing the invention.
