The invention discloses an anti-offset magnetic coupling mechanism and a design method thereof, and an electric vehicle wireless charging system. The anti-offset magnetic coupling mechanism is used for wireless charging of an electric vehicle, and comprises a primary side magnetic energy emission mechanism; wherein the primary side magnetic energy emission mechanism comprises a primary side coil; the primary side coil comprises a primary side main coil and a primary side counteracting coil; and the primary side main coil and the primary side counteracting coil are connected in series in a reverse direction, the primary side main coil and the primary side counteracting coil are both circular coils, and the primary side main coil and the primary side counteracting coil are arranged on the same plane and share the same circle center. According to the wireless charging magnetic coupling mechanism for the electric vehicle, the anti-offset performance can be obviously improved compared with the anti-offset performance of an existing symmetrical wireless electric energy transmission system.

    本发明公开了一种抗偏移磁耦合机构及其设计方法、电动汽车无线充电系统,所述抗偏移磁耦合机构,用于电动汽车无线充电,包括:原边磁能发射机构;所述原边磁能发射机构包括:原边线圈;所述原边线圈包括:原边主线圈和原边抵消线圈;其中,所述原边主线圈和所述原边抵消线圈反向串联,所述原边主线圈和所述原边抵消线圈均为圆形线圈,所述原边主线圈和所述原边抵消线圈设置于同一平面且共圆心。本发明提供的电动汽车无线充电磁耦合机构,其抗偏移性能相对于现有对称的无线电能传输系统抗偏移性能够得到明显的提升。
