城市纯电动中型客车的总体设计1.doc

摘 要 随着能源问题和环境问题的日益突出，现有车辆使用的动力方式已经不能很好的适应未来社会发展的需要。为此，电动汽车的发展得到了广泛的关注，各种类型的电动汽车也在研究和开发之中。 本研究的目的就是为了积累电动客车相关方面的技术，主要对电动汽车进行了总体设计研究，其中包括：分析了部分电动机的优缺点，选择永磁直流电动机作为动力源；对电动汽车的动力性进行了分析，通过最高车速、最大爬坡度和加速时间校核了电动机的性能；介绍了部分蓄电池的性能特点，选择铅酸蓄电池作为能量源；对电动机的控制策略进行了研究，提出蓄电池管理系统总体结构和各部分功能，并对蓄电池组电压、电流、温度和均衡充放电模块进行了总体设计研究；对整车再生制动的结构和控制进行了设计研究；讨论了电动汽车电动机及传动系统的结构和布置方案，设计了蓄电池组的布置位置和安放结构，同时对制动系统进行了初步改装设计。 全套图纸，加 关键词：纯电动汽车改装设计；电动机控制系统；蓄电池管理系统；再生制动  ABSTRACT Being more and more serious along with the energy problems and the environmentproblems, the motive method of the existing vehicle used cant satisfy the demand of thesocial development in the future .For this, the development of EV gotten an extensive concern,various types of EV is also being in the research and the development. The purpose of this research is to accumulated electric bus techniques.This researchmainly carried on a total design to the electric passenger car, the works are as follow:Ianalyzed the merit and shortcoming of some electric motors, and choosed the permanencemagnet DC motor to be the motive source;analyzed the motive of the electric passenger car,examine the performance of the electric motor;introduced the function characteristics of somestorage batteries, and choosed the Lead-acid storage battery to be the energy source;study thecontrol strategy of the electric motor, put forward total structure of the storagebattery management system and each parts of functions, and carried on a design and researchto each part; designed the structureand the control of the regenerative braking system; discussed electric motor and transmissionto equip of constitute and the decoration project, designed the decoration position of thestorage battery set and install structure, in the meantime first step to design a refit project ofthe the brake system, to carryon.
