State Energy Storage Fire Extinguishing System

Can foam extinguishing agent be used in energy storage station fire?

DNV GL did not recommend the use of foam extinguishing agent in the fire of energy storage stations because the battery module fire required rapid cooling to dissipate heat. Compared with water, foam had more difficulty penetrating the gap of battery packs and cooling the insides of batteries. 4.3.4. Liquid Nitrogen

Can gas fire extinguishing agents reduce the temperature of battery?

Gas fire-extinguishing agents such as Halons, HFC-227ea, CO 2 and Novec 1230 are beneficial to integrity protection of battery system during the fire extinguishing process. However, gas fire-extinguishing agents could not effectively reduce the temperature of battery.

Which fire extinguishing agent has a high heat capacity?

A high heat capacity is most essential characterization parameter for reducing the temperature of battery. Obviously, water-based fire-extinguishing agents possess excellent cooling capacity. Among water-based fire-extinguishing agents, the durable heat capacity of F-500 is highest, followed by water and foams.

Why is a battery pack a fire extinguisher?

Generally, the battery pack arrangement is tight to increase the system volumetric energy density, which makes the fire-extinguishing agents hard to access to the inner of the battery pack. Therefore, the deep-seated and inaccessible fire is difficult to be extinguished.

Which extinguishing agent is effective in suppressing Lib fire?

Russoa et al. compared the inhibition of CO 2, foam extinguishing agent, water mist, water, and dry powder extinguishing agent on LIB fire, and found that water and foam extinguishing agent might be effective in suppressing LIB fire. The comparison results are shown in Figure 13.

Is fire suppression equipment included in an ESS?

suppression equipment may or may not be provided as an integral part of an ESS, or it may be optional. Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational.
