In this paper,a vehicle dynamics model and a battery life attenuation model were established for a hybrid dual-motor plug-in hybrid vehicle.At the same time,to reflect the influence of battery temperature on battery life,a battery temperature model was also established.Considering the impact of energy management control on energy economy and battery life decay,a energy management strategy of multi-mode logic rules was developed,and the impact of different control parameters on energy economy and battery life was analyzed.A multi-objective optimization model with equivalent fuel consumption and battery life attenuation was established to optimize the energy management strategy control parameters based on multi-objective improved genetic algorithm.The results show that the Pareto optimal solutions based on the design and optimization method of PHEV(plug-in hybrid electric vehicle)energy management strategy in this article are feasible in terms of both energy consumption economy and battery life of plug-in hybrid vehicles.With many different optimal solutions of control parameters,it provides a variety of alternative schemes for the design and application of PHEV energy management strategy.
