The invention relates to an endurance mileage estimation method and device of an electric vehicle and the electric vehicle. The method comprises the steps that a battery temperature, a battery healthdegree and a battery charge state of the electric vehicle are acquired; the endurance electric quantity of a battery is determined according to the battery temperature, the battery health degree and the battery charge state; and the endurance mileage of the electric vehicle is determined according to the endurance electric quantity. According to the technical scheme, when the endurance electric quantity of the battery is estimated, the influence of the battery temperature, the battery health degree and the battery charge state on the endurance electric quantity is comprehensively considered, so that the determined endurance electric quantity adapts to the use state of the battery, and the accuracy of the determined endurance electric quantity is improved; and the endurance mileage of the electric vehicle is estimated according to the endurance electric quantity of the battery, so that the accuracy of the endurance mileage estimation result of the electric vehicle is improved.

    本公开涉及一种电动车辆的续航里程估算方法、装置及电动车辆。该方法包括:获取电动车辆的电池温度、电池健康度和电池荷电状态;根据电池温度、电池健康度和电池荷电状态确定电池的续航电量;根据续航电量确定电动车辆的续航里程。通过上述技术方案,在估算电池的续航电量时,综合考虑电池温度、电池健康度和电池荷电状态对续航电量的影响,使得确定出的续航电量与电池的使用状态相适应,提高确定出的续航电量的准确性,并根据该电池的续航电量估算电动车辆的续航里程,提高了电动车辆的续航里程估算结果的准确度。
