Abstract

The invention aims to resume the use of battery packs under the situation that batteries can not be used because of the activation of the safety protection function due to bad firmwares, and provides a battery pack, a battery pack firmware updating method and a battery pack system which work normally based on a firmware updated already. In the battery pack (31), a firmware is stored in a flash memory (51). A battery controller (43) executes the firmware stored in the flash memory (51) to perform error detection in the battery pack (31). When an error is detected, the safety protection function is activated, and then the error detection is conducted. When no error is detected, erroneous detection is determined, the firmware stored in the flash memory (51) is rewritten as an updated firmware, and the activation of the safety protection function is reset.

Description

technical field [0001] The invention relates to a battery pack, a battery pack firmware update method and a battery pack system. Background technique [0002] Notebook personal computers (hereinafter referred to as "notebook PCs"), which are typical portable electronic devices, tend to increase their maximum power consumption year by year as the operating frequency of the CPU increases. In addition, because it is necessary to meet the requirements of long-term operation and small and lightweight batteries, lithium-ion secondary batteries with high energy density have become mainstream among batteries used in notebook PCs in recent years. To efficiently use the battery pack by managing the state of charging and discharging efficiently, the battery pack itself has a microcomputer, which controls charging and discharging while exchanging information with the main body of the notebook PC. The structure of the battery device is called a smart battery. The smart battery is a batt...
