基于中国城市道路循环的纯电动乘用车动力匹配

Power system parameters matching of Pure Electric Passenger Car Based on China Urban Road cycle

纯电动车动力系统参数匹配是整车设计的核心内容之一,要综合考虑电机、电池的特性和整车的性能要求。动力系统参数匹配的主要内容包括电机功率、转速,电池容量以及传动系速比等。文章进行了动力系统参数的计算和匹配,在ADVISOR软件中进行整车和各部件模型的搭建并基于中国城市道路循环对匹配结果进行模拟,验证匹配合理性。

Power system parameters matching is one of most important contents of electric vehicle design. Storage battery and electric motor characteristics together with vehicle performance requirements should be considered synthetically. Power system parameters contain battery capacity, motor power, transmitting ratio, etc. This paper calculate and match the power system parameters, set up the model of the vehicle and components with the software ADVISOR and simulation with the use of china urban road cycle to verify the reasonableness of the matching.
