BMS can be regarded as the product of the integration of various functional elements. BMS will include control modules, display modules, communication modules, electrical modules, small battery modules, and information acquisition modules. Diversified modules provide BMS with rich and important functions. These modules can detect the voltage, current, and temperature of LiFePO4 batteries in real-time through sensors, and also perform leakage detection, thermal management, battery balance management, and alarm reminders. , and can also calculate the state of charge (SOC) status, etc. It is really powerful. These functions are critical for LiFePO4 batteries, so there is a saying that the battery pack must be equipped with a Battery Management System.
