A review of power management strategy for plug-in hybrid electric vehicles

The plug-in hybrid electric vehicle has large battery capacity, can be charged from the external power grid, has the advantages of both fuel power and electric drive system,it is considered to be the optimal transition scheme from traditional fuel vehicle to pure electric vehicle. Energy management system is the key to realize the distribution of the demand energy between engine and motor. The economy and power performance of the plug-in hybrid electric vehicle are closely related to the energy management strategy adopted. In this paper, the current situation of the energy management strategy for the plug-in hybrid electric vehicle is reviewed. The merit and demerit of rule-based and optimization-based energy management strategies are compared. The problems and impact of driving data and traffic information on the energy management strategy are emphatically analyzed. Finally, the development trend of energy management strategy is pointed out, to provide a reference for the research of plug-in hybrid electric vehicle.
