辅助混合动力电动汽车技术研究Ⅵ——续驶里程的仿真及实验

Study on the Auxiliary Hybrid Electric Vehicle Ⅵ:Simulation and Experiments of Driving Range

为研究辅助混合动力电动汽车续驶里程,以ADVISOR2002为工具,仿真分析了纯电动汽车和辅助混合动力电动汽车在2种控制策略下的部件效率、续驶里程和百公里油耗．根据仿真结果确定了辅助混合动力电动汽车采用开关式控制策略,最后设计并进行了道路实验．结果表明,在蓄电池数最减少一半的情况下,辅助混合动力电动汽车在续驶里程上与纯电动汽车相当．

The work about the driving range of an AHEV （auxiliary hybrid electric） is studied in this paper. First, the system structure and working principle of the SHEV is expounded, and then a simulation study is made about the components working efficiency, driving range and fuel economy of the original electric vehicle （EV） and the AHEV under two different control strategy using ADVISOR2002. Based on the simulation results, the series on/off control strategy is determined. Under the control strategy, the driving range of the AHEV is equivalent to that of the EV even when battery numbers are halved. Finally, road experiments are designed and performed.
