摘　　要：电动汽车动态无线充电过程中发射线圈与接收线圈会存在纵向与横向的偏差,纵向的偏差是不可避免的也是必要的,但若横向偏差过大则会导致电能传递效率大幅度衰减。为了解决此问题,该文提出了一种实时检测电动汽车动态无线充电时横向偏差的方法,利用四线圈检测电路对其偏差进行检测,在Maxwell、Simplorer与Simulink中建立联合仿真模型。对每个检测线圈进行多点测量来模拟动态无线充电的全过程,并对系统接收侧的电压进行整流和稳压控制。最终仿真结果验证了该方法的有效性。During the dynamic wireless charging of electric vehicles,there will be longitudinal and lateral deviations between the transmitter coil and the receiver coil.The longitudinal deviation is inevitable and necessary.However,if the lateral deviation is too large,the efficiency of power transmission will be greatly reduced.In order to solve this problem,this paper proposes a real-time method to detect the lateral deviation of electric vehicles during dynamic wireless charging.The four-coil detection model is used to detect the deviation,and a joint simulation model is established in Maxwell,Simplorer and Simulink.Multi-point measurement is performed on each detection coil to simulate the whole process of dynamic wireless charging,and the voltage on the receiving side of the system is rectified and regulated.The final simulation results verify the effectiveness of the method.
