Overall high voltage BMS solution:
High-Voltage BMS consists of a GCE battery management unit (BMU) , GCE rack battery management system(RBMS). RBMS includes all the hardware, software and connectors required to integrate a battery stack into your energy storage system (ESS) or UPS. The BMU connect directly to the battery cells to monitor voltage and temperature and perform cell balancing by cascading connection till to RBMS. RBMS includes contactors/relays and a pre-charge resistor to manage connection and disconnection to the DC bus, a auto emergency stop (E-Stop) breaker, and a wide range of connectivity options for integration, insulation, with the ESS.
For more information about the individual components of the High-Voltage BMS, see Battery Management System Modules or download the User Manuals.
