The Economic Analysis of a Plug-In Series Hybrid Electric Vehicle in Different Energy Management Strategy

This paper establishes the system model of a plug-in series hybrid electric vehicle, chooses typical city driving cycle of Chinese passenger vehicle as driving cycle and daily trip mileage of 150km. Two basic energy management strategies of CD-CS and Blended are used to compare the economic indicators of power and fuel consumption. On that basis, this paper summarizes up the fuel economy potential of the plug-in series hybrid vehicles. The simulation results show that, compared with the conventional fuel vehicle, in the driving cycle used in this paper, using CD-CS strategy and APU thermostat control method has the maximum efficiency. If not considering power consumption, the fuel saving ratio can reach 72.98%.
