System Module
The Battery Management System (BMS) is the "intelligent brain" of an energy storage system, dedicated to comprehensive and precise management of the battery pack. It continuously monitors key parameters such as battery voltage, current, and temperature to accurately estimate the battery's state of charge (SOC), ensuring operational safety and providing fault warnings. The BMS employs advanced battery balancing technology to minimize performance differences between individual battery cells, extending the overall lifespan of the battery system. Furthermore, the BMS works in conjunction with the power conversion system and energy management system to optimize charging and discharging strategies, improving overall efficiency and reliability. As a critical component ensuring safety and performance, the BMS is an indispensable core component of electrochemical energy storage systems.
