TEST VIDEO (3 of 4): Sprinklered Fire Test an 83 kWh Energy Storage System Comprised of Lithium Iron Phosphate Batteries FM Global has conducted research on 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. All testing was conducted during 2018 at the FM Global Research Campus in Rhode Island, USA.
Lithium iron phosphate batteries: 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. Two ESS racks were located side-by-side to monitor the potential for fire spread. The results from this test may not be representative of other LFP based systems.
