High Voltage Battery Management System for Energy Storage BAU Level 3 Architecture
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, responsible for collecting battery voltage, temperature and other information of the battery module.
