针对电化学储能的“浸默式”消防系统研究

An"immersed"fire protection system for electrochemical energy storage

为保证电化学储能行业的安全发展,针对磷酸铁锂电池系统,提出一种“浸默式”电池消防系统解决方案。试验采用过充方式触发电池热失控,伴随明火燃烧,研究电池包在火灾场景下,“浸默式”消防系统的抑火效果。结果表明,针对磷酸铁锂电池热失控引发的消防安全事故,“浸默式”消防系统不仅能够快速灭火,还能有效抑制热蔓延,保证了磷酸铁锂电池系统的安全性。

To ensure the safe development of the electrochemical energy storage industry,an"immersed"battery fire protection system was designed and experimented for the lithium-iron phosphate battery system.The experiment uses overcharge to trigger the thermal runaway of the battery,accompanied by the burning of open fire,and studies the fire suppression effect of the"im‑mersed"fire protection system of the battery pack in the design fire scenarios.The experiment results show that the"immersed"fire protection system can not only extinguish the fire quickly,but also effectively inhibit the heat spread of lithium-iron phosphate battery,and ensure the safety of lithium-iron phosphate battery system.
