增程式电动汽车用无刷化双转子磁通切换电机及其复合式驱动系统研究

The new type of extender range electric vehicles (EREVs) have the advantages of high efficiency, high energy-saving and high endurance mileage, which have become one of the hot spots in the field of electric vehicles in recent years. In this project, by incorporating the theory of dual-rotor motor into the flux-switching motor, a new brushless dual-rotor flux-switching permanent magnet motor and the compound drive system is proposed for EREVs. The proposed motor and drive system have the advantages of high integration, flexible control, high power density and high energy transmission efficiency while overcoming the deficiencies in the current EREVs, where the series topology of "(Universal) extended range and pure electric vehicles" are often used. Basic principle and optimized design method of this motor will be investigated in details. The new dynamic allocation and optimization of the control method in dual energy source system will be studied under different operation conditions. Moreover, multi-objective optimization theoretical model and the optimal control strategies will be studied to obtain the high efficient in engine, generator, vehicle drive motor and battery. The project will explore the different power structure in EREVs and establish a multi-objective optimal operation control strategy, which lay a theoretical foundation and provide experimental evidence for the applications of EREVs.
