The battery cabinet is mainly
installed with a battery box and a BMS main management system, supporting wires
and cables, and high and low voltage electrical protection components. The
cabinet adopts a grouped and layered design, which has a beautiful appearance.
The cabinet adopts maintenance-free technology and modular assembly structure
to ensure that the cabinet structure has good mechanical strength, and the
overall structure can meet the reliability
and safety of the entire system to the greatest extent. The battery system is composed
of 10 layers and 1 column.
