摘要
为减少电动车火灾事故的发生,提高电动车安全管理水平,收集和整理了2018年—2022年发生的206起电动车火灾事故报告,分析引发电动车火灾的主要风险因素,并探讨各因素的耦合作用对电动车火灾事故的影响.基于N-K模型构建电动车火灾事故多风险因素耦合模型,并进行耦合交互信息值的计算,得到不同风险因素耦合发生的概率.研究表明:参与耦合的风险因素数量增加,耦合值也相应增加,各因素之间的相互影响愈加密切.物-环境-管理是三因素耦合中造成电动车火灾事故风险最大的耦合因素;人-物是双因素耦合中造成电动车火灾风险最大的耦合因素,减少风险因素耦合能降低事故发生的概率.研究成果可为电动车火灾事故的防控提供理论参考和决策支持.
In order to reduce the occurrence of electric vehicle fire accidents and improve the level of electric vehicle safety management,206 reports of electric vehicle fire accidents that occurred from 2018 to 2022 are collected and organized.The main risk factors that caused electric vehicle fires are analyzed,and the coupling effect of various factors on electric vehicle fire accidents is explored.Based on the N-K model,a multi risk factor coupling model for electric vehicle fire accidents is constructed,and the coupling interaction information values are calculated to obtain the probability of different risk factor coupling occurring.Researches have shown that as the number of risk factors involved in coupling increases,the coupling value also increases accordingly,and the mutual influence between various factors becomes increasingly close.Material environment management is the coupling factor that causes the highest risk of electric vehicle fire accidents among the three factors.Human object is the coupling factor that causes the highest risk of electric vehicle fire in the dual factor coupling.Reducing the coupling of risk factors can lower the probability of accidents occurrence.The research results can provide theoretical reference and decision support for the prevention and control of electric vehicle fire accidents.
