The invention discloses an endurance mileage prediction method and device, an electric vehicle and a computer readable storage medium, and the method comprises the steps: obtaining the temperature data of each battery cell in the electric vehicle, correcting the initial remaining power of the electric vehicle according to the temperature data, and obtaining the actual remaining power, calculating the remaining mileage according to the actual remaining electric quantity and the average energy consumption of the electric vehicle, obtaining a distance error based on the accumulated mileage data and the historical speed data obtained in the first time period, correcting the remaining mileage according to the distance error, and determining the actual endurance mileage of the electric vehicle. According to the embodiment of the invention, the actual residual electric quantity is obtained based on temperature data correction, and the residual mileage is recalibrated by accumulating the mileage data and the historical speed data, so that the prediction error of the endurance mileage can be reduced, and the accuracy of endurance mileage prediction is improved.

    本发明公开了一种续航里程预测方法、装置、电动车与计算机可读存储介质,该方法包括:获取电动车中各电芯的温度数据,并根据温度数据对电动车的初始剩余电量进行修正,得到实际剩余电量,根据实际剩余电量和电动车的平均能耗计算剩余里程,基于第一时间段内获取到的累计形式里程数据和历史速度数据获取距离误差,再根据该距离误差修正剩余里程,确定电动车的实际续航里程。本实施例基于温度数据修正得到实际剩余电量,并通过累计行驶里程数据和历史速度数据重新标定剩余里程,能够减小续航里程的预测误差,提高了续航里程预测的准确性。
