Simulations are often preferred to determine if an explosion prevention system can effectively mitigate gas concentrations according to NFPA 69 standards. CFD methodology can assist with the performance-based design of explosion prevention systems containing exhaust systems.
To address the safety issues associated with lithium-ion energy storage, NFPA 855 and several other fire codes require any BESS the size of a small ISO container or larger to be provided with some form of explosion control. This includes walk-in units, cabinet style BESS and buildings.
Primarily, energy storage space systems have to meet strict security demands. These include fire and explosion avoidance, chemical threat mitigation, and electrical safety. The systems should be developed to avoid and include thermal runaway events, which can bring about fires or explosions.
Determine the upper and lower limits of explosion by dichotomy, that is, take the average of the two combustible concentrations of explosion occurrence and non-occurrence, and repeat the experiment three times for each of the two concentration points to ensure the accuracy of the explosion limit.
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.
In the ejecta from two phases of the battery, EMC has the lowest explosion limit and optimal explosion concentration, at 2.85 % and 8.6 % respectively, making it the most prone to explosion with maximum explosive power. The explosion limits of TR gas range widely from 7.45 % to 39.5 %.
