Study on the electrical vehicle's dynamic performance based on a prototype

动力性能参数选择和仿真技术是研究开发电动汽车的关键技术之一。文章从工程设计和实车试验的角度出发,提出了基于实例的电动汽车动力性能研究方法。在理论分析和工程计算的基础上,对关键部件电机、电池等动力参数进行了匹配研究,并运用ADVISOR进行动力性能的仿真,最后通过试验对动力性能参数进行了验证。

In the development of an electrical vehicle（EV）, selection and simulation of the dynamic performance parameters are key techniques. In the paper, the research method of EV＇s dynamic performance based on the prototype is presented. The electric motor and the battery are studied, and the dynamic parameters are matched on the basis of theoretic calculation and analysis. Simulation of the dynamic performance of the designed EV is carried out by using ADVISOR; and the field test is made. The results demonstrate the feasibility of the proposed method for matching the dynamic performance parameters of an EV.
