摘要: 基于某梯次电池储能系统实际工程项目需求,结合电池热失控机理,提出了基于VOC、可燃气体、温度、烟雾等的多级预警系统及分级预警策略,对电池进行全周期、连续性监测,确保快速有效地检测出电池热失控状态,实现灭火系统的早期介入。在传统的七氟丙烷灭火系统基础上,增加水喷淋灭火系统,确保能够有效扑灭火灾。以退役磷酸铁锂电芯热失控为例验证了该系统的有效性。

Abstract: Based on the actual project requirements of a echelon battery energy storage system, combined with the thermal runaway mechanism of lithium iron phosphate battery, a multi-level warning system and hierarchical early warning strategy based on VOC, combustible gas, temperature, smoke, etc. were proposed to monitor the battery in a full cycle and continuous manner to ensure the rapid and effective detection of battery thermal runaway state and realize the early intervention of fire extinguishing system. Considering the characteristics of low cost, poor safety and reignition of battery fire, a water spray fire extinguishing system was added to the traditional heptafluoropropane fire extinguishing system to ensure the complete extinguishing of the fire. Finally, the effectiveness of the fire warning system was verified by taking the thermal runaway of retired lithium iron phosphate battery as an example.

Key words: battery energy storage system, thermal runaway, multi-level fire warning system, hierarchical early warning strategy, reignition
