中文摘要：

对轮毂电机驱动型电动汽车的动力系统进行了研究。首先分析了轮毂电机驱动型电动汽车行驶时的受力情况,然后以某型号轮毂电机驱动型电动汽车为样车选取了轮毂电机和蓄电池,采用ADVISOR建立了轮毂电机驱动型电动汽车动力系统模型,并对其进行了仿真分析。仿真结果验证了所选取的轮毂电机及蓄电池均满足设计要求。最后利用自行设计的电动汽车骨架样车进行了实验,验证了仿真的合理性。

英文摘要：

A power system of electric vehicle driven by in-wheel motors was studied.First,force conditions of the running electric vehicle driven by in-wheel motors were analyzed.Then,the in-wheel motors and lead-acid batteries were selected with a certain type electric vehicle driven by in-wheel motors as a sample.A power system model of electric vehicle driven by in-wheel motors was built and simulated based on ADVISOR.The simulation result showed that the selected in-wheel motors and lead-acid batteries could meet the design requirement.Finally,the electric frame car designed was tested to prove the reasonableness of the simulation.
