Prospects of energy storage fire automatic extinguishing system

Are large-scale fire extinguishing experiments necessary?

Therefore, before the fire extinguishing agent is used in energy storage stations, large-scale fire extinguishing experiments are necessary to truly evaluate the effectiveness and authenticity of the fire extinguishing agents and methods.

How effective is ln fire extinguishing?

LN can effectively suppress fires in all four hazard stages with minimal harm to the battery and no risk of secondary disasters. Additionally, the gas-liquid synergistic strategy also demonstrates outstanding suppression effects, and the cooling efficiency of extinguishing agents can be further enhanced through intermittent spraying techniques.

What is fire extinguishing agent immersion suppression?

However, the area of fire extinguishing agent attached to the battery surface is small, and the cooling effect is insufficient. Fire extinguishing agent immersion suppression is also a new method of battery thermal runaway suppression. The battery module is immersed in some media (silicone oil, HFE_7100 and water) .

Which fire extinguishing agents are used for battery fires?

Based on the understanding of fire extinguishing mechanism, new fire extinguishing agents have been developed for battery fires, such as hydrogel fire extinguishing agents and liquid nitrogen fire extinguishing agents.

Why is a fire extinguishing agent important?

Due to the high voltage characteristics of BESS and the re-ignition phenomenon of LFP batteries, the selection of fire extinguishing agents and the design of fire extinguishing measures are particularly important for the safety of BESS.

Does fire extinguishing agent affect LFP battery fire?

The effects of five fire extinguishing agents on 243 Ah LFP battery fires were also compared . The extinguishing effect of the fire extinguishing agent on LFP battery fire is ranked as follows: 3 % F-500 > C 6 H 12 O > 6 % Fireice > water fine > HFC-227ea.
