Sprinklered Test of an 83 kWh Energy Storage System Comprised of Lithium Iron Phosphate Batteries

TEST VIDEO (3 of 4): Sprinklered Fire Test an 83-kWh energy storage system comprised of Lithium Iron Phosphate Batteries. FM researched lithium-ion battery-based energy storage systems (ESS) in an industry collaboration with the Property Insurance Research Group through the National Fire Protection Association's Fire Protection Research Foundation. We conducted all tests in 2018 at the FM Research Campus in Rhode Island, USA. The following test was a large-scale evaluation of the performance of ceiling-level sprinkler protection at mitigating the fire hazard posed by an ESS comprised of lithium iron phosphate batteries (LFP). The ESS had an overall electrical capacity of 83 kWh, and all batteries were at a ≥95% state of charge. We placed these two ESS racks side-by-side to assess the potential for fire spread. These results may not be representative of other LFP-based systems.
