Overall high voltage BMS(HV 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.
