Embodiment Construction
[0057] As mentioned earlier, the characteristic of small capacity batteries is that their internal resistance is relatively large, making it difficult to continuously provide large currents. When continuous high current occurs, the battery voltage will drop sharply, and the current will rise after the high current passes. This characteristic is more obvious on older batteries. This characteristic has the potential to cause the system to malfunction. For example, put an old button battery into the remote control, and the voltage is 3.0V when the current is small. At this time, some operations such as FLASH operation and reading and writing will consume part of the current. If the battery voltage drops below the allowable voltage of FLASH work In this case, it is possible to cause FLASH damage during operations such as FLASH read and write, and then lead to catastrophic consequences such as system crash and damage.

A battery management method and device for a low-power consumption device, the method comprising: detecting whether the low-power consumption device has a large current output; when detecting that the battery has a large current output, acquiring The minimum value and the average value of the battery power; when it is determined that the difference between the minimum value and the average value of the battery power is greater than the preset power difference, a low power warning notification is issued. By adopting the above battery management method and device, the battery of the low power consumption device can be effectively managed to avoid system failure.
Description
technical field [0001] The invention relates to the technical field of battery management, in particular to a battery management method and device for low power consumption equipment. Background technique [0002] Low-power devices, such as Bluetooth Low Energy (BLE), etc., have low power consumption characteristics, so small-capacity batteries, such as button batteries, can be used. Small-capacity batteries are characterized by large internal resistance, which makes it difficult to continuously provide large currents. In some cases, it may cause system failures. To avoid this problem, it is necessary to effectively manage the batteries of low-power devices to avoid system failures. However, there is currently no solution for effectively managing the battery of low-power devices. Contents of the invention [0003] The problem solved by the embodiment of the present invention is to manage the battery of the low power consumption device to avoid system failure. [0004] In...
