The bus cabinet serves as the DC-side bus control unit of the energy storage battery system, connecting the high-voltage box and the storage converter. It integrates the power pool system (stack), optional fuses or circuit breakers, a three-level Battery Management System (BMS/ESMU), and a UPS power supply.
The design considers the electrical characteristics, heat dissipation, safety performance, and operational convenience, offering a compact structure, flexible configuration, and high reliability.
The three-level BMS module (ESMU) within the bus cabinet includes CAN, RS-485, and RJ45 Ethernet communication interfaces. These enable seamless communication with the high-voltage box, PCS/UPS, or EMS, supporting data exchange and control for the energy storage battery management system while ensuring robust system protection.
