How do I design an explosion prevention system for an ESS?

The critical challenge in designing an explosion prevention system for a ESS is to quantify the source term that can describe the release of battery gas during a thermal runaway event.

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.

Does the explosion prevention system work with other fire protection features?

The explosion prevention system functionality presented in this work is limited to removing flammable battery gas generated due to the non-flaring decomposition of batteries and does not consider its interactions with other fire protection features. 1. Introduction

What happens if the explosion prevention system is activated?

These values drop to approximately 2 g after the explosion prevention system has been activated. The global concentration of the battery gas inside the failing half stack cabinet is above the 25% LFL limit for less than 1 min before the explosion prevention system is activated for both failure scenarios.

Should deflagration venting be used as passive explosion protection?

In general, using deflagration venting as passive explosion protection in addition to an active system has multiple benefits due to the nature of the battery failure event, which involves a rapid release of flammable gases.
