System and the battery which upon failure of the battery pack analysis method and system

摘要

The present invention is a method of analyzing the failure of a battery pack when the system and the battery are combined. More specifically, after the system and the battery pack are combined, the main IC of the battery is switched to a wake-up state to turn the main power supply FET. -Analyze the defect of the battery pack by measuring and recording the voltage and current of the battery cell within a predetermined time immediately after turning on, and controlling the firmware operation of the system by comparing the measured voltage and current value with a predetermined range It relates to a method and system.
