摘要在能源枯竭和环境危害的双重压力下，电动汽车的优越性越来越受到关注，众多企业都投入巨资力求取得划时代的技术突破。

该文首先报告了电动汽车的现状，分析了电动汽车的结构，再生制动的工作原理，再生制动与摩擦制动配合工作的必要性以及能量回收的控制策略。然后根据本课题所设计的整车参数，先确定需要满足的设计条件，再选择电机电池等部件。最后应用ADVISOR，对整车、电机、电池组、两挡变速器和道路工况进行了建模，在软件中进行仿真分析。60949

从仿真结果知，该车辆一次充电续驶里程达230.7km，最高车速达41.2km/h,最大爬坡度为21.9%，百公里油耗3.8L，除了0到40km/h加速时间超出设计标准2.6s外,所建的电动汽车性能参数基本能达到设计要求。并且还对使用不同电池进行了对比，分析电机的效率、电池荷电状态、再生制动系统运行的实际情况。

Title   The simulation research of Electric Vehicle that has the function of braking energy feedback

Abstract

Under the double pressures of energy depletion and environmental hazards,

the advantages of electric cars are more and more taken seriously. Many countries formulate encouraging policies to support electric vehicle research, and a great deal companies increase the electric vehicle technology investment to grab the opportunities. 

The report analyses the present situation of the electric vehicles, briefly describes the working principle of regenerative braking of electric vehicle, and analyzes the various aspects of factors that restric the electric vehicle regenerative braking .  it also discusses the needing of coordinate control of the  regenerative braking and the traditional friction braking. then according to the design of the vehicle, select the motor battery etc. 

Finally, I use ADVISOR to build the model of transmission, vehicle, motor, battery pack, and two speed transmission, then do simulation analysis in the software to study energy feedback efficiency. And compare with different batteries , analysis of motor efficiency, battery charged state,and the actual situation of regenerative braking system operation.
