Parameter matching and simulation of power system of extented-range electric vehicle

为了使增程式电动汽车动力系统的关键部件驱动电机、蓄电池及增程器在最佳工作区域运行,首先在对增程式电动汽车结构分析的基础上,根据整车基本参数及性能指标要求,对动力系统各部件的参数进行匹配,然后在Cruise仿真软件中对动力性进行仿真。仿真结果表明,满足增程式电动汽车对动力性能指标的要求,参数匹配合理,为后续控制策略的研究及经济性仿真提供理论基础。

In order guarantee the optimal working conditions of the key components of the power system of the extended-range electric vehicle,including the drive motor,the storage battery and the range extender,we analyzed the structure of the extended-range electric vehicle,matched the parameters of each part of the power system according to the basic parameters and performance requirements of the vehicle,and then simulated the power performance in Cruise software.The simulation results show that the parameter matching can meet the power performance requirements.This study has provided theoretic basis for future researches on the control strategy and the economic efficiency of the vehicle.
