The invention relates to the technical field of vehicle safety, in particular to an electric vehicle power battery safety system which comprises a battery anomaly detection module, a feature anomaly detection module, an abnormal condition analysis module and a spontaneous combustion prevention device control module. The battery abnormity detection module is used for detecting operation data of a battery pack; the feature anomaly detection module is used for detecting smoke data and temperature data of a measurement point; the abnormal condition analysis module is used for analyzing whether the operation of the battery pack is abnormal or not according to the operation data of the battery pack and the smoke data and the temperature data of the measurement points, and generating an abnormal condition analysis result; and the spontaneous combustion prevention device control module is used for controlling starting and stopping of the spontaneous combustion prevention device according to the abnormal condition analysis result. According to the scheme, spontaneous combustion of the vehicle can be avoided in time, and the spontaneous combustion risk detection accuracy is improved.

    本发明涉及车辆安全技术领域,尤其是一种电动汽车动力电池安全系统,包括电池异常检测模块、特征异常检测模块、异常情况分析模块和防自燃装置控制模块;所述电池异常检测模块,用于检测电池包的运行数据;所述特征异常检测模块,用于检测测量点的烟雾数据和温度数据;所述异常情况分析模块,用于根据电池包的运行数据、测量点的烟雾数据和温度数据,分析电池包的运行是否存在异常情况,并生成异常情况分析结果;所述防自燃装置控制模块,用于根据异常情况分析结果,控制防自燃装置的启闭。采用本方案,能够及时避免车辆自燃,并提升自燃风险检测的准确性。
