Abstract
A battery pack is disclosed. The battery pack includes a battery, an impact sensor, a processor and a memory. The impact sensor is capable of generating an impact signal in response to a detection of an impact on the battery pack. The processor is capable of generating impact information based on the impact signal, and processor continues to count a number of charging times to the battery after the generation of the impact information. The memory is capable of storing the impact information and the number of charging times. The processor can refer to the memory to deliver a control command to a battery charger so that the battery can only be charged up to an allowable charge capacity smaller than a full charge capacity after an occurrence of an impact when the battery pack is attached to the battery charger. The charging to the battery stops when the number of the counted charging times reaches a predetermined number of allowable charging times that is allowed after the generation of the impact information.
