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.
One delayed explosion battery ESS incident is particularly noteworthy because the severe firefighter injuries and unusual circumstances in this incident were widely reported (Renewable Energy World, 2019).
Deflagration pressure and gas burning velocity in one important incident. High-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
Incidents of battery storage facility fires and explosions are reported every year since 2018, resulting in human injuries, and millions of US dollars in loss of asset and operation.
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.
A stranded ESS battery, which is commonly found after an ESS fire has been extinguished and the battery terminals have been damaged, poses a shock hazard to those working with the damaged ESS. It still contains an unknown amount of electrical energy, and this stranded energy can also lead to reignition of a fire within minutes, hours, or even days after the initial event.
