Cause of fire at energy storage station

What happens if an energy storage station fires?

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. For example, in 2024, three LFP battery energy storage station fire accidents occurred in Germany within three months .

What causes large-scale lithium-ion energy storage battery fires?

Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. This leads to damage of battery system enclosures.

What causes a fire accident in energy storage system?

The investigation report concluded that the fire accident in the energy storage system was caused by excessive voltage and current due to the surge effect during system recovery and startup. This was not effectively protected by the BMS system.

Are there fires and explosions in lithium battery energy storage stations?

There have also been considerable reports of fires and explosions in lithium battery energy storage stations. According to incomplete statistics, there have been over 30 incidents of fire and explosion at energy storage plants worldwide in the past 10 years.

What are the characteristics of fire and explosion of energy storage stations?

And the fire and explosion of energy storage stations have certain characteristics, mainly including: the types of accident batteries are mostly ternary lithium-ion batteries, and most of them occur during charging and rest periods.

How to protect battery energy storage stations from fire?

High-quality fire extinguishing agents and effective fire extinguishing strategies are the main means and necessary measures to suppress disasters in the design of battery energy storage stations . Traditional fire extinguishing methods include isolation, asphyxiation, cooling, and chemical suppression .
