The 2016 Fire Protection Research Foundation (FPRF) 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 these systems including two full-scale open-air tests from the 2016 FPRF 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. The Property Insurance Research Group (PIRG) and FM Global have initiated this project to determine sprinkler protection guidance for lithium ion (Liion) battery based energy storage systems (ESS) located in commercial occupancies. Through small-scale and large-scale experimental testing this project will inform sprinkler protection guidance and provide recommendations for standards development.
Research goal: The overall goal of this project is to determine sprinkler protection guidance for grid connected ESS for commercial occupancies, i.e., 100 to 1,000 kWh capacities. The fire hazard for a range of commercial ESS designs will inform protection requirements.
