BCU
The BCU is swappable and supports power conversion, current equalization, and BCU (intra-cabinet BMS) management.
- When the voltages of battery strings are inconsistent, the BCU controls the current balance between battery strings through voltage boosting and balance adjustment to ensure reliable system operation.
- The BCU implements communication inside a SmartLi cabinet and between cabinets, and provides battery management and protection against exceptions.
