This paper describes a dynamic simulation model built to assess Plug-in Hybrid Electric Vehicles (PHEVs) performance and lithium-ion battery performance installed in PHEVs. First, we examine vehicle performance. In particular, the effects of engine on/off controls and the effects of drive distance are evaluated, because they have significant impact on PHEVs environmentally friendly performance. A study of cycle life test methods for batteries installed in PHEVs is also examined. Here, we discuss the establishment of a common PHEV battery charge/discharge test profile for Japan, the US, and Europe.

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.
