The battery management system (BMS) is the "center" of the entire battery pack, which is responsible for monitoring the running status of each battery cell in the pack to ensure its safe and reliable operation. It monitors and collects the running parameters of the battery in real time for SOx analysis and calculation, and realize effective control of the battery based on specific protection control strategies, so as to ensure the safe and reliable operation of the entire battery system. At the same time, BMS interacts with other external devices through its own interface to establish linkage control of other systems and ensure the safe, reliable and efficient operation of the power supply system.
