The invention discloses a method for quickly calculating the power consumption of a whole electric vehicle. The method comprises the following steps: acquiring basic parameters of a to-be-tested electric vehicle and driving test data under different working conditions; establishing a whole vehicle power consumption model according to the basic parameters and the driving test data, wherein the power output of the whole vehicle power consumption model is related to the discharge characteristic, the speed and the acceleration of the battery; and decomposing a whole vehicle power consumption calculation task under a specified working condition into parallel tasks according to a time step length, and inputting the parallel tasks into the whole vehicle power consumption model to obtain a whole vehicle power consumption prediction value under the specified working condition. According to the method, the power consumption of the whole vehicle can be quickly calculated, a user and a manufacturer can know the energy consumption condition of the electric vehicle more quickly and more conveniently, and a scientific basis is provided for improving the performance of the electric vehicle and optimizing electric energy management.

    本发明公开了一种电动汽车整车电耗快速计算方法,包括以下步骤:获取待测试电动汽车的基本参数和不同工况下的行驶测试数据;根据所述基本参数和行驶测试数据建立整车电耗模型,所述整车电耗模型的功率输出与电池放电特性、速度和加速度相关;将指定工况的整车电耗计算任务按时间步长分解成并行任务,并输入所述整车电耗模型,得到指定工况的整车电耗预测值。本发明实现了对整车电耗进行快速计算,用户和制造商能够更快速、更方便地了解电动汽车的能耗状况,为提升电动汽车性能、优化电能管理提供科学依据。
