This paper presents modeling, control strategy and simulation results of an energy management strategy (EMS) for a specific plug-in hybrid electric vehicle (PHEV). A good control strategy is required among components, such as the energy storage system, an electric motor, a power control unit, and an internal combustion engine in order to ensure that the vehicle achieve an improvement in energy efficiency, reduction in emissions, fuel use, weight and cost. In this work, firstly, through a power flow analysis, the vehicle components are sized to meet the expected power and energy requirements of a typical 5- passenger car. Then, the model is tested numerically in the MATLAB/SIMULINK environment using the highway fuel economy test drive cycle with the proposed EMS. The accuracy of the model is verified by a comparison between the simulation results from a specific PHEV code and advanced vehicle simulator (ADVISOR) hybrid electric vehicle (HEV) model. The simulation results of the two different HEV models are compared and the pros and cons discussed.
