Ecolite High Voltage BMS Battery Management System For Energy Storage BMU64

Ecolite Highly Functional Level 3 High Voltage Battery Management System for Energy Storage BMU64

Diagram of Energy storage Level 3 Architecture System:
Level 3 battery system architecture: First level control: BAU centrally man-ages the various clusters of batteries inthe battery array, and communicateswith external PCS, UPS, EMS, airconditioning, liquid cooling, fire protec-tion, etc;
Secondary control: BCU1~BCUmmanaging each cluster of batteriescollecting cluster battery information,high-voltage control, and uploadingcluster information to BAU;

Slave control:BMU1~BMUn, responsi-ble for collecting battery voltage,temperature and otherinformation ofthe battery module.
