A Battery Management System (BMS) is an electronic system that manages rechargeable batteries by monitoring their state, controlling their environment, and protecting them from operating outside safe limits. It ensures the safe operation and optimal performance of batteries by monitoring key parameters such as voltage, temperature, and state of charge (SOC)23. The BMS also enhances battery longevity and performance by preventing damage and ensuring efficient usage5. [pdf]
