Power system modeling and performance evaluation of series/ parallel-type plug-in hybrid electric vehicles

Abstract

In this paper, a simulator was built to simulate a plug-in hybrid electric vehicle (PHEV) power system. Specifically, a model adopting a series/parallel hybrid system with a planetary gear mechanism was created. With this model, the impacts of the engine on/off control and drive distance on environmental performance were analyzed using a homologation driving schedule for Japan. It was proven that when providing PHEVs to the market it will be necessary to adjust the engine on/off control to suit the actual daily drive distance of users.
