GCE 864V 400A 5U case master BMS relay contactor BMS insulation display 270 series parallel function for ESS UPS
Our high voltage BMS has complete battery charge and discharge control logic and balance function between batteries. We can also set various parameters of the system according to the actual needs of customers to ensure the stability, reliability and efficient performance of the system.
Our high-voltage BMS includes slave control BMU, harness and standard 19 inch master control BMS chassis. The slave control BMU is installed into each battery module, and then connected to the master control BMS through cascade mode.
This is our the 4th generation high voltage bms.It's an overall bms solution, that is to say,You don't need professional technology to install our high-voltage BMS to form a complete battery system.
