The invention discloses wireless charging equipment and a method for electric automobiles. The wireless charging equipment comprises a charging coil and a power receiving coil. The charging coil is embedded in the ground. A first silicon steel iron core is inserted into the charging coil; the power receiving coil is mounted at the bottom of an electric vehicle. The wireless charging equipment hasthe following beneficial effects: the charging coil installed on ground, space is saved, and at the same time, abrasion of charging equipment is avoided, the service life of the charging equipment isprolonged; most of magnetic lines emitted by the charging coil pass through the silicon steel iron core and a silicon steel iron core extension core and pass through all the power receiving coil, a magnetic line loop is formed. The size of the silicon steel iron core and the silicon steel iron core extension core can bear the required magnetic flux, the size of the power receiving coil can bear the required charging current, the distance of the silicon steel iron core is shortened through the rotation of the silicon steel iron core extension core, and the wireless charging requirement of the electric automobiles is met.
本发明公开了一种电动汽车无线充电设备以及方法,包括充电线圈以及受电线圈,所述充电线圈嵌装于地面上,所述充电线圈上插装有第一矽钢铁芯,所述受电线圈安装于电动汽车底部,本发明的有益效果是,充电线圈安装在地面,不占用空间,同时避免了充电设备磨损,延长了充电设备的使用寿命,充电线圈发射的磁力线绝大部分通过矽钢铁芯、矽钢铁芯延长芯穿过全部受电线圈,形成磁力线回路,矽钢铁芯、矽钢铁芯延长芯的大小能承受所需的磁通量,受电线圈的大小能承受所需的充电电流,通过矽钢铁芯延长芯的转动,拉近了矽钢铁芯的距离,满足了电动汽车的无线充电要求。
