摘要

为了研究不同灭火剂对储能电池模块的性能ꎬ，搭建了储能舱试验平台。以8􀆰8 kWh磷酸铁锂储能电池模块为研究对象ꎬ以0􀆰5 C速率恒流过充ꎬ为研究对象，对4种灭火剂ꎬ(中压细水雾ꎬNovec1230ꎬ七氟丙烷和六氟丙烷)的灭火性能进行了实验比较。结果表明，六氟丙烷不能在短时间内扑灭电池火灾，而Novec1230和七氟丙烷可以快速扑灭，但不能有效冷却，有重燃倾向ꎬ，不适合作为磷酸铁锂电池组件的灭火剂。但ꎬ中压细水雾能快速灭火，连续喷射防止重燃ꎬ，是理想的灭火材料。

Study on performance of gas-liquid extinguishing agent for lithium iron phosphate battery modules

In order to study performance of different extinguishing agents for energy storage battery modulesꎬ an energy storage cabin test platform was built. With lithium iron phosphate energy storage battery module of 8􀆰 8 kWh as research objectꎬ fire was induced by thermal runaway from 0􀆰 5 C rate constant current overchargeꎬ and experiments were conducted to compare performance of four fire ̄ extinguishing agentsꎬ including medium ̄pressure water mistꎬ Novec1230ꎬ 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 reigniteꎬ all of which are not suitable to be fire extinguishing agent for lithium iron phosphate battery modules. Howeverꎬ medium ̄pressure water mist can quickly extinguish fire and prevent re ̄ignition with its continuous injectionꎬ thus making an ideal fire extinguishing material.
