The invention provides an electric vehicle endurance mileage abnormity identification method, system and device and a medium, and the method comprises the steps: obtaining signal data in each journey of a vehicle, the signal data comprising a charge state and an accumulated mileage; the travel is obtained by dividing two adjacent charging time nodes; if the charge state range in the travel comprises a preset charge state range, determining the driving mileage in the preset charge state range according to the accumulated mileage; determining an actual endurance mileage coefficient in the corresponding journey according to the driving mileage; and comparing the actual endurance mileage coefficient with a theoretical endurance mileage coefficient, and outputting abnormal information when determining that the endurance mileage of the vehicle is abnormal in the corresponding travel according to a comparison result. According to the invention, the vehicle with abnormal endurance mileage can be identified, reliable data support is provided for after-sales service, and good user experience is ensured.

    本申请提供一种电动汽车续航里程异常识别方法、系统、设备和介质,包括:获取车辆各行程内的信号数据,其中,所述信号数据包括:荷电状态以及累计里程;所述行程根据相邻两个充电时间节点划分得到;若所述行程内的荷电状态范围包含预设荷电状态范围,则根据所述累计里程确定所述预设荷电状态范围内的行驶里程;根据所述行驶里程确定对应行程内的实际续航里程系数;将所述实际续航里程系数与理论续航里程系数进行比对,根据比对结果确定对应行程内车辆续航里程异常时输出异常信息。本申请可即使识别车辆续航里程异常的车辆,为售后服务提供可靠的数据支撑,保证良好的用户体验。
