How can Bess reduce the risk of fire and explosion incidents?

By incorporating advanced safety features, we can significantly reduce the risk of fire and explosion incidents. One of the most critical components in BESS safety is the Battery Management System (BMS). The BMS continuously monitors and controls various parameters such as cell voltage, temperature, and state of charge.

What causes fire & explosion inside a Bess enclosure?

The leading cause of fire and explosion inside a BESS enclosures is the release and ignition of combustible vapors from an overheating battery.

What are the key codes for energy storage systems?
