摘要/Abstract

摘要： 为研究不同灭火剂对储能电池模组火灾有效性,搭建储能舱试验平台,选取8.8 kWh磷酸铁锂储能电池模组,以0.5 C倍率恒流过充诱发电池热失控至起火,灭火试验采用中压细水雾、Novec1230、七氟丙烷、六氟丙烷4种不同灭火剂,对比不同灭火剂的灭火效能。研究结果表明:六氟丙烷无法在短时间内扑灭明火;Novec1230和七氟丙烷2种气体灭火剂能快速扑灭明火,但降温效果不彻底,容易发生复燃,均不适合作为磷酸铁锂电池模组灭火剂;中压细水雾能迅速扑灭明火,持续喷射可防止复燃,是较为理想的灭火材料。

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.

Key words: energy storage cabin, lithium iron phosphate battery, thermal runaway, extinguishing agent, battery module
