Development of Control Strategy and Energy Management for Plug-in HEV

Plug-in Hybrid Electric Vehicle (PHEV) is considered as the next design objective of hybrid electric vehicle (HEV). It combines the advantages of electric vehicle (EV) and HEV. PHEV has full electric drive mode which can be applied in relative short distance and HEV mode which can be used for long distance. In this paper, the powertrain model of the PHEV is obtained. Based on the analysis of the powertrain model, the control strategy and energy management strategy of PHEV are developed. The PHEV simulator is constructed MATLAB/Simulink. Using the powertrain model and the control strategies, simulations are performed and the simulation results are analyzed. Finally, the plug-in Prius simulator is validated by using the PSAT. It is expected that the PHEV performance can be used for the designers to develop a PHEV.
