    摘要:

    电动汽车无线电能传输(electric vehicle wireless power transfer, EV-WPT)技术具有巨大的应用前景。但是车辆停靠过程中,由于各种因素导致耦合机构未对准或者发生角度偏移,从而降低系统的充电功率、效率甚至充电失败等。为解决上述问题,设计出一种新型的耦合机构,实现耦合机构全向的抗偏移能力;用杂间距的设计方式增强能量线圈之间的互感的同时,减小发射线圈的自感,减少了线圈绕制的用线量。另外利用双D型线圈与Q型线圈的解耦特性,将接收线圈与接收端补偿线圈做磁集成处理,节省了空间以及磁芯的用量;最后,搭建输出功率达1.4 kW的仿真模型,验证系统良好的抗偏移能力和恒流输出效果。

    Abstract:

    Electric vehicle wireless power transfer (EV-WPT) technology holds promising application potential. However, during vehicle parking, misalignment or angular deviation in the coupling mechanism can reduce charging power, efficiency, and may even cause charging failure. To address these issues, this paper presents a novel coupling mechanism with omnidirectional anti-offset capability. Additionally, the design method incorporates stray spacing to increase mutual inductance between energy coils, reduce the self-inductance of the transmitting coil, and minimize the wire required for coil winding. Leveraging the decoupling characteristics of dual D-type and Q-type coils, the receiving coil and the receiving-end compensation coil are magnetically integrated, saving space and reducing the amount of magnetic core material needed. Finally, a simulation model with 1.4 kW output power is developed to verify the system’s robust anti-offset capability and stable constant current output.
