BCU + BMU Guaranteed Safety and Performance

Each module has a capacity of 10.24kwh, with an output of 102.4V 100Ah. Its operating voltage range is 672-784V, and the charge-discharge current is 45A/0.3C.

These modules use a BCU to monitor the operating status of every single cell, which helps prevent issues like overcharging, over-discharging, overheating, and short circuits.

The BMU unit on the top connects to each BCU, forming an intelligent BMS. This setup ensures the entire system operates safely and with high efficiency.
