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.
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.
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.
