The embodiment of the invention provides a method and device for determining the endurance mileage of an electric vehicle, and the method comprises the steps: obtaining actual battery data, actual environment temperature data and actual driving state data of an electric vehicle, processing the actual battery data, the actual environment temperature data and the actual driving state data based on a preset comprehensive mileage prediction model, obtaining a first endurance mileage, then determining a mileage calibration model applied to the first endurance mileage based on the driving state data, and finally calibrating the first endurance mileage by using the mileage calibration model to obtain a second endurance mileage of the electric vehicle, so that the deviation between the second endurance mileage and the actual endurance mileage is lower than the deviation between the first endurance mileage and the actual endurance mileage. Thus, the deviation in the endurance mileage obtaining process is reduced, and the accuracy in the endurance mileage obtaining process is improved.

    本发明实施例提供了一种电动汽车续航里程确定方法及装置,通过获取电动汽车的实际电池数据、实际环境温度数据以及实际行驶状态数据,并基于预设的综合里程预估模型处理实际电池数据、实际环境温度数据以及实际行驶状态数据,得到第一续航里程,然后基于行驶状态数据,确定出应用于第一续航里程的里程校准模型,最后,利用里程校准模型对第一续航里程进行校准,得到电动汽车的第二续航里程,使得第二续航里程与实际续航里程的偏差小于第一续航里程与实际续航里程的偏差,因而减小了获取续航里程过程中的偏差,提高了获取续航里程过程中的准确度。
