摘 要
在全球石化能源面临枯竭的背景下，世界各国开始寻找适合本国的新能源产品以优化能源结构、面对能源和环境危机。这样的市场环境为新能源汽车，尤其是纯电动汽车提供了良好的发展机遇。
本文以市场对纯电动汽车的需求和纯电动汽车应对交通拥堵和节能减排方面的优势出发，确定了一款用于城市正常出行用的小型纯电动代步汽车作为设计对象。参考市场上成熟的小型车产品的整车参数和布局方式，综合代步需求和国家对纯电动汽车使用的技术要求，确定了小型纯电动汽车的前置前驱的布局方案以及整车的动力性、经济性要求。
根据电动汽车动力驱动系统的设计流程，考虑已有的纯电动汽车的整车参数和动力性、经济性指标，完成对设计的小型纯电动汽车的驱动电机的选型和匹配。再凭借电动机最高转速和车辆最高车速的对应关系以及电动机输出转矩和车辆的动力性能的对应关系完成电动汽车传动系统的设计工作。完成传动系统设计后，可以顺利建立电动机的能量需求和动力电池的能量的匹配关系，进一步完成动力电池组的选型和匹配。
将建立的驱动电机系统和动力电池系统的参数代入理论计算公式进行电动汽车整车性能的验算。进一步确定电动汽车的整车设计参数，依据整车设计参数建立设计的小型纯电动汽车的数据模型。使用ADVISOR软件对电动车数据模型进行纽约城市道路工况和等速50km/h工况下的电动车性能仿真，得到仿真的动力性能和经济性能于理论验算结果相比较，论证设计方案的合理性与可行性。

Abstract
Under the global petrochemical energy depletion, the world began to find suitable new energy products to optimize national energy structure and face the challenges of energy and environmental crisis. This demand provides a good opportunity for new energy vehicles, especially pure electric vehicles , to developing in market.
According to the market demand for pure electric vehicles and advantages of pure electric vehicles in reducing traffic congestion, saving energy and decreasing emission, this paper chooses a micro pure electric ferry with a normal travel abilities in the city as a design object. Reference to the market mature small car products’ vehicle parameters and layout and the national technical requirements of pure electric vehicles, this paper has determined dynamic and economic requirements of the micro pure electric vehicle with front-wheel-drive layout.
On the basis of the design process of electric vehicle drive system, this paper completes the design of micro pure electric vehicle driving motor selection and matching considering the existing pure electric vehicle parameters and dynamic, economic indicators. Next, this paper completes the drive system design of the electric vehicle with the corresponding relationship between the maximum speed of the motor and the maximum vehicle speed and the corresponding relationship between the motor output torque and vehicle dynamic performance. Finally, you can successfully establish the relationship between the energy requirements of the motor and the battery power, and further complete the power battery selection and matching with the completion of the transmission system design.
Established drive motor system and power battery system parameters can be used into the theoretical formula for electric vehicle performance checking. Due to determined vehicle design parameters, a data model of the micro pure electric vehicle can be established. Using the ADVISOR software to simulate dynamic and economic performances of the electric vehicle in the New York city road condition and in the constant speed 50km / h condition, the dynamic performance and the economic performance of the simulation are compared with results of the theoretical calculation to evaluate the scientific features and feasibility of the micro vehicle design.
