monitoring equipment, fire protection systems, electricity meters, air conditioning, or
access control systems to form an energy storage system. EMS controls the entire system
and enables functions such as on-grid and off-grid control, peak shaving and valley filling,
demand control, smoothing of renewable energy fluctuations, dynamic expansion, and
optimizing energy storage revenue. EMS collects data and signals from local devices and
ensures the safe, reliable, efficient, and economical operation of the energy storage
system through internal control strategies.

BMS
BMS module is a high-voltage power circuit management unit specially designed for
energy storage system by our company, which is an intermediate unit connecting battery
clusters and energy storage converter. The BMS module is equipped with circuit breakers,
contactors, fuses, current sensors, battery cluster control management module (HVBCU),
switching power supply, etc. It performs functions such as voltage and current acquisition,
circuit contactor control, and protection for battery clusters.
The BMS stabilizes and secures the battery function by monitoring the battery status in
