Highly Functional Level 3 High Voltage Battery BMS For BCU Energy Storage

Highly Functional Level 3 High voltage Battery Management System for BCU Energy Storage

Diagram of Energy storage level 3 Architecture System:
Level 3 battery system architecture:First level control: BAU centrally manages the various clusters of batteries in the battery array, and communicates with external PCS, UPS, EMS, airconditioning, liquid cooling, fire protection, etc;
Secondary control: BCU1~BCUmmanaging each cluster of batteries collecting cluster battery information, high-voltage control, and uploading cluster information to BAU;

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