Lithium-ion battery (LIB) energy storage systems (BESS) are integral to grid support, renewable energy integration, and backup power. However, they present significant fire and explosion hazards due to potential thermal runaway (TR) incidents, where excessive heat can cause the release of flammable gases.
A simulation was conducted to depict the scenario of an explosion occurring in a pack within a 20-foot liquid-cooled energy storage cabin. The 3D model of the simulation is shown in Fig. 3 (a). The dimensions of the cabin are 6 m × 2.4 m × 3 m (length × width × height, with a wall thickness of 0.1 m), which includes 80 LCBPs.

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.
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.
This arrangement makes it difficult to use a standard exhaust ventilation methodology to design an explosion prevention system. An innovative approach is used to purge the battery gas from individual Powin Stacks™ and from the main enclosure during a thermal runaway event.
This paper addresses the safety concerns associated with LCBPs and proposes an effective solution for explosion relief. Installing an electric-controlled pressure relief valve with battery fault detection capability on a liquid-cooled battery pack can prevent explosions caused by thermal runaway. 1. Introduction
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. The battery gas global concentration drops to 8% LFL during the steady operation of the explosion prevention system.
The test results showed that this approach prevented LCBP from explosions effectively. The PRV in LCBPs must be integrated with a novel and effective battery fault monitoring method. This paper only provided one possible solution as a proof-of-concept. Various alternative methods can replace different parts of the PRV.
