Energy Storage High-voltage Control Box
The energy storage high-voltage control box collects the cell voltage and temperature data of all battery modules through the internal CAN interface to protect the battery modules. Due to the function of communication with PCS, and together with the built-in dual switch (circuit breaker + main circuit relay), it can realize the charge and discharge management of the whole battery system, which is safe and reliable.
