Battery Management System (BMS)
BMS consists in 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 HV battery cells and control of internal and external actuators.
