PHEV Mode Selection Strategy for Full Battery Consumption and Known Traffic Condition on Intercity Commuting

Energy management plays important role in achieving maximum fuel efficiency on plug-in hybrid electric vehicle (PHEV). Capability of PHEV using electric (EV) mode and hybrid (HV) mode can be optimized by selecting efficient mode for known route and traffic condition. Typical intercity commuting traffic can be divided into urban/city traffic and highway traffic. This paper presents measurements of PHEV energy consumption per distance for each city and highway traffic case. In case of full battery consumption, the optimal mode selection strategy is determined for each traffic case. This paper shows that the mode selection strategy using known route and traffic condition can achieve less fuel consumption compared to default PHEV configuration or no strategy.
