HV Master BMS
High-voltage master control units (HVCU/BCU) designed for central coordination, insulation tracking, contactor sequencing, and multi-rack parallel ESS management.
The HV Master BMS serves as the central intelligent brain of the high-voltage battery storage system. It coordinates slave units, monitors total pack current/voltage, manages pre-charging and high-voltage contactor sequences, and handles high-level communication with upstream PCS and EMS platforms.
