摘要： 针对多种类型电动自行车混杂停放的火灾现场的原因调查，基于电动自行车火灾案例和锂电池火灾试验，分析锂电池热失控起火和车身电气线路故障起火时的特征差异，总结电动自行车火灾的特殊现场痕迹。结果表明，电动自行车锂电池热失控起火和电气故障（短路）起火在烟雾、声音、火光等方面存在较大差异，现场痕迹也表现出不同的特征，对这些现象痕迹的特征进行归纳总结，可以为电动自行车火灾调查提供参考借鉴。

Abstract: To investigate the causes of fires involving mixed parking of various types of electric bicycles, this study conducted case studies on electric bicycle fires and various lithium battery fire experiments to analyze the differences in characteristics between lithium battery thermal runaway fires and vehicle electrical circuit failures, and to summarize the special on-site traces of electric bicycle fires. The results indicate that there are significant differences in smoke, sound, and light between the thermal runaway ignition and electrical fault (short circuit) ignition of lithium batteries in electric bicycles. The on-site traces also exhibit different characteristics. Summarizing the characteristics of these phenomena and traces can provide reference for the investigation of electric bicycle fires.
