Sprinklered Test of a 125 kWh Energy Storage System Comprised of LNO/LMO Batteries

TEST VIDEO (4 of 4)*: Sprinklered Fire Test of a 125 kWh Energy Storage System Comprised of Lithium Nickel Oxide /Lithium Manganese Oxide 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 nickel oxide with added lithium manganese oxide 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 nickel oxide/lithium manganese oxide batteries (LNO/LMO). The ESS had an overall electrical capacity of 125 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 LNO/LMO based systems. *Battery chemistry was previously reported as lithium nickel manganese cobalt oxide (NMC) The research technical report can be downloaded at: http://www.fmglobal.com/researchreports To learn more about the FM Global Research Campus, visit: http://www.fmglobal.com/research
