Along with the intense heat generated from each affected battery cell during thermal runaway is a dangerous mixture of offgas. According to NFPA 855 (A.9.6.5.6), thermal runaway results in
6 FAQs about [Energy storage explosion-proof requirements]
Can explosion prevention systems mitigate gas concentrations according to NFPA 69 standards?
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.
Does a lithium-ion energy storage unit need explosion control?
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.
Does NFPA 855 require explosion control?
NFPA 855 [*footnote 1], the Standard for the Installation of Stationary Energy Storage Systems, calls for explosion control in the form of either explosion prevention in accordance with NFPA 69 [*footnote 2] or deflagration venting in accordance with NFPA 68 [*footnote 3].
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.
Can CFD be used to design an explosion prevention system?
CFD methodology can be extended to design an explosion prevention system for any ESS enclosure. Results can also provide the controlled release rate of flammable and toxic materials which is useful information for first responders and to assess environmental impacts.
