The invention discloses a battery safety detection method and device for an electric vehicle and the electric vehicle, and belongs to the technical field of electric vehicle safety detection. The battery safety detection method comprises the following steps: controlling a battery management system of the electric vehicle to obtain a wake-up signal; when it is judged that the wake-up signal is the wake-up signal for the external power supply mode of the vehicle, current fluctuation parameters of a battery pack of the electric vehicle within the target time are obtained; under the condition that the current fluctuation parameter reaches the standard, it is judged that the electric vehicle enters a vehicle external power supply mode, and battery operation data of the electric vehicle are obtained; analyzing and processing the battery operation data to obtain a battery safety detection result for the electric vehicle; and outputting a battery safety detection result. According to the method, the accuracy degree of safety detection of the electric vehicle battery can be improved, and timely detection and rapid early warning of abnormal working of the electric vehicle battery are realized.

    本发明公开了一种用于电动汽车的电池安全检测方法、装置及电动汽车,其属于电动汽车安全检测的技术领域。电池安全检测方法包括:控制电动汽车的电池管理系统获取唤醒信号;当判定唤醒信号为针对车辆对外供电模式的唤醒信号时,获取电动汽车的电池包在目标时间内的电流波动参数;在电流波动参数达标的情况下,判断电动汽车已进入车辆对外供电模式,并获取电动汽车的电池运行数据;对电池运行数据进行分析处理,以获得针对电动汽车的电池安全检测结果;输出电池安全检测结果。本发明的方法能够提高电动汽车电池安全检测的准确程度,实现对电动汽车电池工作异常的及时检测和快速预警。
