Since a large amount of energy is stored in the energy storage station in the form of chemical energy, once this energy is released in the form of heat and fire, it will cause serious damage.
Conclusions Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
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.
While lithium-ion battery energy storage systems are a relatively new technology and phenomenon, there have been several notable events where significant fires and explosions have occurred in which thermal runaway was instrumental in the magnitude of the loss.
Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher. After the combustible gas got on fire, the gases volume expanded by high-temperature compresses the volume of the surrounding gases.
Despite their benefits, battery energy storage systems (BESS) do present certain hazards to its continued operation, including fire risk associated with the battery chemistries deployed. Source: Korea Bizwire BATTERY ENERGY STORAGE SYSTEMS EXPLAINED - HOW DOES A BESS OPERATE?
The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection enclosures.
