Parameter Matching and Performance Simulation for Extended Range Electric Vehicle
-
摘要: 为将一款纯电动汽车改装为增程式电动汽车，通过对増程器工作模式和原理的分析，对増程器的发动机与发电机参数进行匹配，得出合理的设计参数。结合MATLAB/Simulink与ADVISOR软件平台对改装前后的整车在相同循环工况（CYC_UDDS）下进行对比仿真分析。结果显示，改装后的增程式电动汽车续驶里程达177.8km，且整车的动力性能与燃油经济性控制在合理的范围内，表明文中所提纯电动汽车改装方案是可行、有效的，为后续实车改造和整车路试实验提供参考依据。Abstract: In order to convert a battery electric vehicle into an extended-range electric vehicle, by analyzing the working patterns and principles of range extender, parameters of engine and generator of the range extender's were matched, and reasonable design parameters were obtained. With the co-simulation platform of MATLAB/ Simulink and ADVISOR, the battery electric vehicle and the extended-range electric vehicle were simulated in the same driving cycle (CYC_UDDS) respectively. Simulation results show that the driving range of the extended-range electric vehicle reaches 177.8 km, meanwhile its dynamic performance and fuel efficiency can be controlled within an appropriate range, which indicates that the modification scheme is reasonable and effective, and it provides the reference for the transformation test and vehicle road test.
