The invention belongs to the technical field of new energy vehicles, and particularly relates to a pure electric vehicle driving range estimation method and device and a pure electric vehicle. The method comprises the steps that first average power consumption of necessary power consumption equipment is determined according to historical power consumption information or first preset power consumption of the necessary power consumption equipment; according to historical power consumption information or second preset power consumption of the air conditioning system, second average power consumption of the air conditioning system is determined; obtaining the current residual available electricity quantity of the battery pack; and determining the remaining driving range according to the first average power consumption, the second average power consumption and the remaining available power consumption. According to the method, when the vehicle electricity consumption time is calculated, the electric energy consumption of driving, air conditioner and battery pack heating is decoupled, the remaining driving mileage is dynamically displayed, and the reliability of the driving mileage estimation result is improved.

    本发明属于新能源汽车技术领域,具体涉及一种纯电动汽车续驶里程预估方法、装置及纯电动汽车,方法包括:根据必要用电设备的历史耗电信息或第一预设电耗,确定所述必要用电设备的第一平均电耗;根据空调系统的历史耗电信息或第二预设电耗,确定所述空调系统的第二平均电耗;获取电池包当前的剩余可用电量;根据所述第一平均电耗、所述第二平均电耗以及所述剩余可用电量,确定剩余续驶里程。本发明在计算车辆电耗时,将行车、空调以及电池包加热的电能消耗进行解耦,动态的显示剩余续驶里程,提高了续驶里程预估结果的可靠性。
