Abstract

In order to study performance of different extinguishing agents for energy storage battery modules, an energy storage cabin test platform was built. With lithium iron phosphate energy storage battery module of 8. 8 kWh as research object, fire was induced by thermal runaway from 0. 5 C rate constant current overcharge, and experiments were conducted to compare performance of four fire-extinguishing agents, including medium-pressure water mist, Novec1230, heptafluoropropane and hexafluoropropane. The results show that hexafluoropropane can not extinguish battery fire within a short time while Novec1230 and heptafluoropropane can extinguish it quickly but can not cool it effectively with a tendency to reignite, all of which are not suitable to be fire extinguishing agent for lithium iron phosphate battery modules. However, medium-pressure water mist can quickly extinguish fire and prevent re-ignition with its continuous injection, thus making an ideal fire extinguishing material. © 2020 China Safety Science Journal.
