The Power Allocation Strategy for PHEV with Hybrid Power System Based on Four-Factor-Method

Along with the hybrid power system mathematical model, three different kinds of power allocation strategies for PHEV with hybrid power system based on four-factor method are put forward, and they are based on super capacitor energy efficiency, PHEV operating environment and electric mechanism. The results of semi-physical simulation verify that the control strategy is effective. Compared with the allocation strategy based on the average motor power, the economy of all in the CD model strategy has the best performance, which can rise by 3.15%. The trend curves about the influences of each factor on economy drawn with the optimization results of SA, have reference value for establishing the power allocation strategy for hybrid power system.
