The 2016 Fire Protection Research Foundation project “Fire Hazard Assessment of Lithium Ion Battery Energy Storage Systems” identified gaps and research needs to further understand the fire hazards of lithium ion battery energy storage systems. There is currently limited data available on the fire hazard of energy storage systems (ESS) including two full-scale open-air tests from the 2016 Foundation project and a separate project that included intermediate scale fire testing conducted at the module level to evaluate the performance of fire suppressants. The fire protection and fire service communities need guidance on protection requirements for these systems in a building.
