Are battery storage systems causing fires & explosions?

Unfortunately, a small but significant fraction of these systems has experienced field failures resulting in both fires and explosions. A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation.

Can explosion prevention system remove battery gas from the enclosure?

The evolution of battery gas in Fig. 13, Fig. 14 shows that the explosion prevention system can remove the battery gas from the enclosure. The 3D contours of battery gas can also help identify local spots where battery gas can concentrate.

Can a flammable battery gas source be used for explosion control?

NFPA 855 recommends that a UL 9540A ( ANSI/CAN/UL, 2019) test be used to evaluate the fire characteristics of an ESS undergoing thermal runaway for explosion control safety systems. An approach to determine a flammable battery gas source term to design explosion control systems has been developed based on UL 9540A or similar test data.

How to design a Bess explosion prevention system?

The critical challenge in designing an explosion prevention system for a BESS is to quantify the source term that can describe the release of battery gas during a thermal runaway event. Hence, full-scale fire test data such as from UL 9540A testing are important inputs for the gas release model.
