The invention discloses a segmented resonant wireless charging coupling coil for an electric vehicle. The coupling coil is wound from outside to inside, the coupling coil is segmented into N segments, a wire inlet end is connected with a first capacitor, an ith compensation capacitor is connected between an (i-1) th segment of coupling coil and an ith segment of coupling coil, and i is greater than or equal to 2 and less than or equal to N; and the ith section of coupling coil and the ith compensation capacitor resonate. Each segmented coil is provided with a series compensation capacitor for resonance compensation. According to the wireless charging coupling coil for the electric vehicle, after the coupling coil is segmented, the voltage of each segment of the coil of the system is reduced, the displacement current of the aluminum plate is reduced, the induced voltage of the aluminum plate is reduced, and the electromagnetic disturbance is reduced, so that the safe operation of the wireless charging system for the electric vehicle is ensured.

    本发明公开了一种电动汽车分段谐振无线充电耦合线圈,耦合线圈外向内绕制,耦合线圈分割为N段,入线端连接第一电容,第i‑1段耦合线圈与第i段耦合线圈之间连接第i个补偿电容,2≤i≤N;第i段耦合线圈与第i个补偿电容谐振。各分段线圈均有串联补偿电容进行谐振补偿。该电动汽车无线充电耦合线圈通过耦合线圈分段后,能够实现系统每段线圈电压变小,在铝板的位移电流变小,铝板的感应电压变小,电磁骚扰降低,从而保证电动汽车无线充电系统安全运行。
