摘　　要： 为了快速、准确及有效地预测电动汽车动力性,建立了电动汽车动力性数学模型,编制了电动汽车动力性仿真程序。以实验室研发的某纯电动汽车为例进行仿真计算,仿真结果与该车道路实测结果基本吻合。对该电动汽车的动力性与能耗灵敏度进行分析,各参数对汽车动力性及能耗的影响以动力传动系的机械效率和汽车的总质量最为显著,分析结果对改善电动汽车整车动力性能及能耗经济性提供了参考。 In order to predict EV power performance rapidly, exactly and effectively, the mathematical model of EV power performance is established and the computer simulation program of EV power performance is compiled. Base on the EV power performance mathematical model, the power performance of an EV is calculated by computer simulation, and the simulation result coincides with what is obtained from the real EV. The parameter sensitivity formulate of power performance and ener- gy consumption of EV are Analyzed and EV power performance and energy consumption are influenced by a variety of parameters, in particular, the mechanical efficiency of power train and gross mass of EV are of the most obvious influence. The analysis provides useful reference to the improvement of EV power performance and energy consumption economy.
