摘要/Abstract

摘要： 针对储能电站典型灾害电池连锁热失控问题,对其热量传播过程及抑制效果开展研究。通过加热板模拟热滥用条件,诱导风冷电池模组内单体发生热失控,并利用液氮作为急冷介质,评估外加急冷措施对模组内电芯间热量传播的抑制效果。基于风冷模组急冷措施对热失控抑制试验,识别热失控传播典型位置,筛选热失控及其传播特征评价指标,进而构建以温度变化为核心的评价模型,实现对急冷措施抑制效果的定量化评价。研究结果可为储能电站急冷措施安全防护的效果评价与优化设计提供理论依据与方法支撑。

Abstract: Focousing on chain thermal runaway, a typical hazard in energy storage power stations, its heat propagation process and suppression strategies is investigated. Under simulated thermal abuse conditions induced by a heating plate, thermal runaway is triggered in a single cell within an air-cooled battery module. Liquid nitrogen is applied as an emergency cooling medium to evaluate the effectiveness of external rapid cooling in mitigating inter-cell heat transfer. Based on experimental research on thermal runaway suppression in air-cooled modules, this study identifies typical locations of thermal runaway propagation, selects evaluation indicators for thermal runaway and its propagation characteristics, and a temperature change-centric evaluation model is constructed to achieve quantitative assessment of emergency cooling suppression effects. The findings provide theoretical foundations and methodological support for evaluating and optimizing the safety protection of emergency cooling in energy storage power stations.
