摘要

开发和研究纯电动汽车是解决环境污染及能源问题的重要手段之一,而动力系统参数匹配设计是纯电动汽车开发工作的基础.本文基于一款已知整车基本参数的纯电动汽车,结合其动力性和经济性的设计需求,通过理论计算完成其动力系统主要部件参数匹配的设计与选型;应用CRUISE仿真软件建立整车模型,对动力性和经济性进行仿真,通过分析仿真结果,证明理论计算的参数匹配合理,达到了设计目标要求,设计过程可为纯电动汽车的动力系统设计开发提供参考.%The development and research of pure electric vehicles is one of the important means to solve environmental pollution and energy problems, and the design of dynamic system parameter matching is the basis of pure electric vehicle development. Based on a known electric vehicle with basic parameters, combined with its design requirements of power and economy, the design and selection of main components matching of power system is completed through theoretical calculation. The CRUISE simulation software was used to build a vehicle model to simulate the dynamic and economic performance. By analyzing the simulation results, it proved that the parameters of the theoretical calculation match reasonably and meet the design goal. The design process can provide a reference for the design and development of the power system of pure electric vehicles.
