The battery management system (BMS) is divided into three levels of management which composed of the collection unit (BMU), battery cluster management unit (BCU), energy management unit (EMU), monitor the condition of the battery (temperature, voltage, current, charge condition, etc.), and to provide a communication port and protection system for the battery.
