Are lithium-ion battery energy storage systems fire safe?

With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.

Can battery energy storage systems cause a fire?

Fire suppression strategies of battery energy storage systems In the BESC systems, a large amount of flammable gas and electrolyte are released and ignited after safety venting, which could cause a large-scale fire accident.

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 .

Does the surface temperature of a SoC LFP battery affect fire behavior?

Liu et al. discussed the battery surface temperature with and without fire behavior conditions and found that the surface temperature of the 100 % SOC LFP battery was higher in fire behavior. Jia et al. discussed the surface temperature of the battery under overcharging and overheating.
