Battery Management System
The BMS consists of Battery Management Controller (BMC), Cell Supervising Circuits (CSCs) and Battery Junction Box (BJB). Functions include functional safety, determination of State of Charge (SOC) and State of Health (SOH), monitoring and balancing of the high voltage battery cells, control of internal and external actuators.
