Battery Energy Storage Systems – FIRE & RISK ALLIANCE

The UL 9540A Test Method evaluates the fire safety hazards associated with propagating thermal runaway within battery systems. The UL 9540A test method includes an evaluation of BESS at three levels: cell, module, and unit. Cell-level testing is conducted to determine if thermal runaway is induced in the cell, and further testing is required.

Mitigating Fire Risks in Battery Energy Storage Systems (BESS)

Battery Energy Storage Systems (BESSs) play a critical role in the transition from fossil fuels to renewable energy by helping meet the growing demand for reliable, yet decentralized power on a grid-scale.
