Modeling and simulation of power assembly for single-axle parallel hybrid electric vehicles

Aiming at the goal of car power performance and economy,a new vehicle power system with Ni-H battery and permanent magnetic synchronous motor (PMSM) is designed,based on the INSIGHT hybrid electric vehicle(HEV). According to property of electric assistance strategy,meeting requirements on vehicle power performance,selection and simulation of the engine parameters,motor parameters and energy matching parameters are enforced on the software redeveloped ADVISOR. The method of forward along with backward simulation was used,and system model was established on the basis of actual situation. The simulation results show the design of the power system for the experimental sample car is practical and feasible. The results provide a theoretical basis for the power assembly optimal design of HEV.
