The invention relates to the technical field of electric vehicles, and especially relates to a method and a device for estimating the remaining mileage of a pure electric vehicle. The method comprisesthe following steps: obtaining the driving data of a vehicle, and receiving an energy consumption rate which is calculated through a prediction condition model built according to the driving data ina cloud system; in preset storage time, based on the prediction working condition model, calculating remaining battery energy through a battery management system; and calculating the remaining mileageof the vehicle according to the energy consumption rate and the remaining battery energy. The remaining mileage of the pure electric vehicle can be estimated based on the daily driving behavior of the driver and the remaining battery capacity, the accuracy of the remaining mileage of the pure electric vehicle is improved, misleading of judgment of the driver in the subsequent driving process is avoided, and the driver can reasonably arrange the charging opportunity and travel.
本发明涉及电动汽车技术领域,具体是一种纯电动汽车的剩余里程预估方法及装置,所述方法包括:获取车辆的行驶数据,接到能量消耗率,所述能量消耗率为在云端系统中,根据所述行驶数据建立预测工况模型,计算出能量消耗率;在预设存储时间内,基于所述预测工况模型,通过电池管理系统计算出剩余电池能量;根据所述能量消耗率与所述剩余电池能量,计算出车辆的剩余里程;本发明能够基于驾驶员日常驾驶行为和剩余电池电量预估出纯电动汽车剩余里程,提高纯电动汽车剩余里程准确性,避免误导驾驶员在后续驾驶过程中的判断,使驾驶员能够合理的安排充电时机和行程。
