The invention discloses an electric vehicle power consumption calculation method and system. The method comprises the following steps: acquiring a standard driving condition corresponding to a target vehicle model; extracting standard average vehicle speeds of a plurality of short strokes and a standard mileage corresponding to each standard average vehicle speed from the standard driving condition; dividing the standard average vehicle speed into a plurality of continuous speed intervals, and obtaining standard power consumption corresponding to each speed interval; acquiring actual driving data corresponding to the target vehicle type; performing interval division on the actual average vehicle speed according to the speed intervals so as to obtain speed interval mileages corresponding to different speed intervals; calculating energy consumption weighting coefficients corresponding to different speed intervals according to the speed interval mileage and the total mileage; and performing weighted calculation on the standard power consumption according to the energy consumption weighting coefficient to obtain the actual power consumption of the target vehicle type. According to the invention, the power consumption of the electric vehicle of a specific vehicle type can be calculated more accurately.

    本发明公开了一种电动车电耗计算方法及系统,该方法包括:获取目标车型对应的标准驾驶工况;从标准驾驶工况中提取多个短行程的标准平均车速以及每个标准平均车速对应的标准里程;将标准平均车速划分为若干个连续的速度区间,并获取每个速度区间对应的标准电耗;获取目标车型对应的实际驾驶数据;按照速度区间对实际平均车速进行区间划分,以获取不同速度区间对应的速度区间里程;根据速度区间里程以及总里程,计算不同速度区间对应的能耗加权系数;根据能耗加权系数对标准电耗进行加权计算,以获取目标车型的实际电耗。本发明能够更准确的计算某一特定车型的电动车的电耗。
