A ground charging system, an electric vehicle wireless charging system and method are disclosed. According to a detected position of a vehicle-mounted end coil, the position of the vehicle-mounted endcoil is orthographically projected to a ground end matrix coil comprising a plurality of sub-coils arranged in a matrix mode, and all the sub-coils, overlapped with the orthographic projection of thevehicle-mounted end coil, in the ground end matrix coil are started; and an electric vehicle is wirelessly charged. According to an alignment condition of the vehicle-mounted end coil and the groundend coil, all the sub-coils, overlapped with the orthographic projection of the vehicle-mounted end coil, in the ground end matrix type coil are opened, charging of the electric vehicle is achieved, acoil loss can be reduced, and energy is saved.
地面充电系统、电动汽车无线充电系统及方法,根据检测到的车载端线圈位置,将车载端线圈位置正投影至包括若干呈矩阵式排布子线圈的地面端矩阵式线圈上,开启地面端矩阵式线圈中与车载端线圈正投影有重叠部分的所有子线圈,对电动汽车进行无线充电。本发明中根据车载端线圈与地面端线圈的对准情况,开通地面端矩阵式线圈中与车载端线圈正投影有重叠部分的所有子线圈,实现对电动汽车的充电,能够减少线圈损耗,节约能源。
