There are no standards defining performance tests of electrical energy storage (EES) system for complex application scenarios that require both photovoltaic (PV) smoothing and electric vehicle (EV) load regulation.
Unfortunately, a small but significant fraction of these systems has experienced field failures resulting in both fires and explosions. A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation.
A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation. EPRI also maintains a database of BESS failures . Some BESS failures have resulted in significant consequences.
NFPA 484 Standard for Combustible Metals, NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergency Response, Canadian Electrical Code’s CSA C22.2 No. 286, and UL 1004-4 Standard for Electric Generators were added as reference standards related to thermal ESS.
Both fires and gas explosions require fuel, oxygen, and an ignition source (heat), as shown in Figure 1. Some useful definitions follow: Explosion: Sudden violent release of energy usually accompanied by the generation of high temperatures and release of high-pres-sure gas. Types include
Although fires and gas explosions both contain fuel and air, several factors influence whether one or the other occurs, including the mixture of the fuel, confinement, and congestion. For a gas explo-sion to occur, a volume must exist where fuel and air are premixed and are within the flammability limits (LFL and UFL).
