For the problem of service life shortening led by power battery overdischarging, the energy management control strategy model to compensate battery discharging was proposed by adding the plugin range extender on the pure electric vehicle. Based on the further development of ADVISOR, the feasibility of energy management control strategy was verified by simulation, which met the power and economy requirements of vehicle. The strategy was optimized by using the case that the battery dropped to the lower limit of set charging range at the end of driving as the optimization object. The results show that the operating time of range extender shortens significantly and the fuel consumption and exhaust emissions reduced greatly.
