[0040] The core of this application is to provide a battery management method, device, equipment and computer storage medium, which can keep the battery working time basically consistent during the use of the battery, avoid frequent charging, and thus reduce the speed of battery aging.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Please refer to Figure 1 , Figure 1 A schematic diagram of a battery management method provided in an embodiment of the present application, refer to Figure 1 As shown, the method includes:

[0043] S101: Detect whether the aging capacity of the battery meets the preset conditions;

[0044] Aging capacity refers to the capacity of the battery that is reduced due to aging. The actual capacity of the battery can be obtained, and the aging capacity of the battery can be obtained by subtracting the full capacity of the battery from the actual capacity of the battery. During the use of the battery, the aging capacity of the battery is detected to see whether it meets the preset conditions. The preset conditions can be whether the aging capacity of the battery is legal, that is, whether it is normal.

[0045] In some embodiments, the step of detecting whether the aging capacity of the battery meets a preset condition includes:

[0046] Determining whether the aging capacity of the battery conforms to the capacity aging trend of the battery;

[0047] If the aging capacity of the battery conforms to the capacity aging trend of the battery, then the aging capacity of the battery meets the preset condition;

[0048] If the aging capacity of the battery does not conform to the capacity aging trend of the battery, the aging capacity of the battery does not meet the preset condition.

[0049] The method for judging whether the aging capacity of the battery conforms to the aging trend of the battery capacity may be: judging whether the aging capacity of the battery is on the variation curve of the aging capacity of the battery. The variation curve of the aging capacity of the battery is obtained by fitting based on a number of previously determined battery aging capacities. If the aging capacity of the battery is on the variation curve of the aging capacity, the aging capacity of the battery is normal; if the aging capacity of the battery is not on the variation curve of the aging capacity, the aging capacity of the battery is abnormal.

[0050] Another method for determining whether the battery aging capacity conforms to the battery capacity aging trend is to calculate the slope of the aging capacity change curve (a straight line in this case) based on the battery aging capacity and the last determined battery aging capacity, and determine whether the slope is consistent with the slope calculated previously. If they are consistent, the battery aging capacity is normal; if they are inconsistent, the battery aging capacity is abnormal, and there may be a jump in aging capacity.

[0051] S102: If satisfied, compensating the actual capacity of the battery according to the aging capacity of the battery and the preset initial capacity of the battery; the preset initial capacity is less than or equal to the difference between the full-charge capacity of the battery and the maximum aging capacity of the battery; the maximum aging capacity is the aging capacity of the battery when it reaches the preset maximum cumulative working time;

[0052] Perform an aging test on the battery in advance to obtain the maximum aging capacity of the battery, wherein the maximum aging capacity of the battery is the aging capacity of the battery when the battery reaches the preset maximum cumulative working time during the aging test.

[0053] For example, during the aging test of the battery, the cumulative working times of the battery are respectively recorded as T1, T2, and T3, where T1 < T2 < T3. When the cumulative working time of the battery is T1, the battery experiences 5% aging, that is, the aging capacity of the battery is 5%, and the aging capacity of this battery is recorded as C1. When the cumulative working time of the battery is T2, the battery experiences 10% aging, that is, the aging capacity of the battery is 10%, and the aging capacity of this battery is recorded as C2. When the cumulative working time of the battery is T3, the battery experiences 15% aging, that is, the aging capacity of the battery is 15%, and the aging capacity of this battery is recorded as C3. T3 is the preset maximum cumulative working time, and C3 is the maximum aging capacity of the battery obtained from the test.

[0054] Based on the full charge capacity of the battery and the maximum aging capacity of the battery, determine the preset initial capacity of the battery, and this preset initial capacity is less than or equal to the difference between the full charge capacity of the battery and the maximum aging capacity of the battery. The initial full charge capacity of the battery is 100%.

[0055] In some embodiments, the preset initial capacity of the battery is equal to the difference between the full charge capacity of the battery and the maximum aging capacity of the battery.

[0056] The full charge capacity of the battery is recorded as C0, and the maximum aging capacity of the battery obtained from the test is recorded as Cmax. Then the initial capacity of the battery is C0 - Cmax. Since the full charge capacity of the battery is 100%, the initial capacity of the battery is C0 - Cmax = 100% - Cmax.

[0057] If the aging capacity of the battery meets the preset conditions, then compensate the actual capacity of the battery according to the aging capacity of the battery and the preset initial capacity of the battery. Use the compensated actual capacity of the battery as the full charge standard for battery charge and discharge management.

[0058] Among them, in some embodiments, compensating the actual capacity of the battery according to the aging capacity of the battery and the preset initial capacity of the battery includes:

[0059] Update the actual capacity of the battery to the sum of the preset initial capacity and the aging capacity of the battery.

[0060] Let the aging capacity of the battery be C, then the actual capacity of the updated battery is C0-Cmax+C. As the battery is used, it ages and has aging capacity, and the actual value of the full capacity of the battery has not reached the initial 100%. The aging capacity of the battery is C, then the value of the full capacity C0 of the battery is actually equal to 100%-C. The actual capacity of the updated battery is equal to 100%-C-Cmax+C=100%-Cmax, so the actual capacity of the battery is always maintained at 100%-Cmax during use. If the battery power is consumed by 100%-Cmax, it is considered that the battery power is exhausted and needs to be charged. If the battery charge reaches 100%-Cmax, it is considered that the battery power is fully charged. Therefore, within the service life of the battery, the battery usage time is always the time when the power is consumed by 100%-Cmax, so that the battery usage time can be kept consistent.

[0061] S103: If not satisfied, determining whether the accumulated working time of the battery reaches a preset accumulated working time;

[0062] S104: If reached, the actual capacity of the battery is compensated according to the aging capacity corresponding to the preset accumulated working time and the preset initial capacity.

[0063] If the aging capacity of the battery does not meet the preset condition, it is determined whether the cumulative working time of the battery reaches the preset cumulative working time, and when the cumulative working time of the battery reaches the preset cumulative working time, the actual capacity of the battery is compensated according to the aging capacity corresponding to the preset cumulative working time and the preset initial capacity. The working time of the battery stored last time can be obtained from the memory, and the working time of the battery stored last time and the working time of the battery this time are added to obtain the cumulative working time of the battery.

[0064] In addition to storing the working time of the battery, the memory can also store the aging capacity of the battery. When the device is shut down or restarted, the recorded cumulative working time and the aging capacity of the battery can be stored in the memory.

[0065] In some embodiments, compensating the actual capacity of the battery according to the aging capacity corresponding to the preset accumulated working time and the preset initial capacity includes:

[0066] The actual capacity of the battery is updated to the sum of the preset initial capacity and the aging capacity corresponding to the preset accumulated working time.

[0067] For example, when the cumulative working time of the battery reaches the preset cumulative working time T1, the actual capacity of the battery is updated to the sum of the preset initial capacity and C1, that is, the actual capacity of the battery is updated to C0-Cmax+C1. When the cumulative working time of the battery reaches the preset cumulative working time T2, the actual capacity of the battery is updated to the sum of the preset initial capacity and C2, that is, the actual capacity of the battery is updated to C0-Cmax+C2.

[0068] In some embodiments, it also includes:

[0069] If the cumulative working time of the battery does not reach the preset cumulative working time, the cumulative working time of the battery is continuously counted until the cumulative working time of the battery reaches the preset cumulative working time, and the actual capacity of the battery is compensated according to the aging capacity corresponding to the preset cumulative working time and the preset initial capacity.

[0070] When the cumulative operating time of the battery has not reached the preset cumulative operating time, this embodiment does not temporarily compensate the actual capacity of the battery, and continues to count the cumulative operating time of the battery until the cumulative operating time of the battery reaches the preset cumulative operating time, and then compensates the actual capacity of the battery according to the aging capacity corresponding to the preset cumulative operating time and the preset initial capacity.

[0071] For example, if the cumulative working time of the battery has not reached the preset cumulative working time T1, the actual capacity of the battery will not be compensated temporarily, and the cumulative working time of the battery will be continuously counted until the cumulative working time of the battery reaches the preset cumulative working time T1, at which time the actual capacity of the battery will be updated to the sum of the preset initial capacity and the aging capacity corresponding to the preset cumulative working time T1.

[0072] Alternatively, in some embodiments, when the cumulative operating time of the battery has not reached the preset cumulative operating time, the aging capacity of the battery can be periodically re-determined, and it can be determined whether the aging capacity of the battery meets the preset conditions. Until the aging capacity of the battery meets the preset conditions, the actual capacity of the battery is compensated according to the aging capacity of the battery and the preset initial capacity of the battery.

[0073] In some embodiments, it also includes:

[0074] An aging test is performed on the battery to determine the aging capacity corresponding to each preset cumulative working time; the aging capacity corresponding to the preset cumulative working time includes the maximum aging capacity of the battery.

[0075] The number of preset cumulative working hours can be set differently. For example, the number of preset cumulative working hours and the value of each preset cumulative time can be determined according to the service life of the battery. For example, if the service life of the battery is 3 years, the number of preset cumulative working times can be determined in units of years to be 3, namely 1 year, 2 years and 3 years.

[0076] refer to Figure 2 As shown, a specific implementation is described below:

[0077] Perform aging tests on the batteries equipped with the equipment to determine the aging capacity corresponding to the preset cumulative working time.

[0078] When the device starts, the initial capacity of the battery is set to the difference between the full-charge capacity of the battery and the maximum aging capacity obtained during the aging test. During the startup process, the aging capacity of the battery stored last time is obtained, and the actual capacity of the battery is updated to the difference between the initial capacity and the aging capacity of the battery.

[0079] The device starts the timing service, obtains the working time stored when the device was last shut down, and records the cumulative working time as the sum of the working time and the current working time.

[0080] During the operation of the equipment, the aging capacity of the battery is regularly checked to see if it is normal. If it is normal, the actual capacity of the battery is updated to the difference between the initial capacity and the aging capacity of the battery. If it is abnormal, it is determined whether the cumulative working time of the battery has reached the preset cumulative working time. If a preset cumulative working time has been reached, the actual capacity of the battery is updated to the sum of the initial capacity of the battery and the preset cumulative working time reached.

[0081] If the device is shut down or restarted, the recorded cumulative working time and aging capacity are stored in the memory so that the actual capacity of the battery can be determined the next time the device is started.

[0082] In summary, the battery management method provided by the present application determines the initial capacity of the battery based on the full-charge capacity of the battery and the maximum aging capacity of the battery. The initial capacity is less than or equal to the difference between the full-charge capacity of the battery and the maximum aging capacity of the battery, thus reserving part of the battery capacity for subsequent capacity compensation. The compensation for the battery aging capacity during actual use of the battery ensures that the actual capacity of the battery remains consistent throughout the entire life cycle of the battery, and the battery usage time can remain consistent, avoiding the problem of frequent charging of the battery after long-term use, thereby alleviating the speed of battery aging and improving the user experience.
