The invention provides a new energy vehicle remaining mileage calculation method and device, and the method comprises the steps: obtaining the remaining available energy of a power supply in a vehicle, the first energy consumption of a driving assembly in a first preset mileage, and the second energy consumption of an electric appliance in a second preset mileage, the first preset mileage and the second preset mileage are driving mileages of the vehicle from previous different moments to the current moment, and the second preset mileage is greater than the first preset mileage; dividing the first energy consumption by a first preset mileage to obtain unit mileage driving energy consumption of the driving assembly, and dividing the second energy consumption by a second preset mileage to obtain unit mileage power consumption of the electric appliance; adding the unit mileage driving energy consumption and the unit mileage electricity consumption to obtain the unit mileage energy consumption of the vehicle; and dividing the remaining available energy by the energy consumption per unit mileage to obtain the remaining mileage of the vehicle. The calculation of the energy consumption per unit mileage of the vehicle is more accurate, and the accuracy of estimating the remaining mileage of the vehicle can be obviously improved.

    本申请提供一种新能源汽车剩余里程的计算方法及装置,方法包括:获取车辆中电源的剩余可用能量、驱动组件在第一预设里程中的第一能耗以及用电器在第二预设里程中的第二能耗,其中,第一预设里程和第二预设里程为车辆从先前不同时刻至当前时刻行驶的里程,第二预设里程大于第一预设里程;将第一能耗与第一预设里程相除,得到驱动组件的单位里程驱动能耗,以及,将第二能耗与第二预设里程相除,得到用电器的单位里程用电能耗;将单位里程驱动能耗与单位里程用电能耗相加,得到车辆的单位里程能耗;将剩余可用能量与单位里程能耗相除,得到车辆的剩余里程。使得车辆的单位里程能耗的计算更加精准,能够明显提高车辆剩余里程估算的准确性。
