Lithium-Ion Battery Energy Storage System Enclosure

Coffman assisted a top energy storage system manufacturer with the design of their latest utility grade 8 MWh lithium-ion ISO container battery enclosure. Coffman’s engineering services included multiple fire and thermal runaway safety hazard analyses.

• A bow-tie based hazardous mitigation analysis (HMA) was developed to better understand the possible outcomes of a fire or thermal runaway event.
• Coffman provided guidance for developing test plans for full-scale deflagration and Large Scale Fire Testing (LFST) of the proposed battery enclosure.
• Fire modeling using FDS software was completed to evaluate the potential spread of fire to adjacent equipment during a fire event. Fire modeling was calibrated to the results of the large-scale fire test.
• Gas dispersion and explosion modeling were completed using FLACS modeling software to justify the explosion vent relief panel design. FLACS modeling was calibrated to the results of the full-scale deflagration test.
