The invention discloses a wireless charging method and system for an electric vehicle, and the method comprises the following steps: carrying out the alignment of a transmitting coil and a receiving coil in the vehicle, and then moving the transmitting coil, so as to enable the transmitting coil to move towards the receiving coil in the vehicle; when the transmitting coil moves to a preset distance, the vehicle starts to be charged; after the vehicle is charged, the transmitting coil begins to be away from the receiving coil, and charging is stopped. The system comprises an alignment device, a charging device and a control system. According to the method disclosed by the invention, the light weight of the wireless charging transmitting end can be realized, and the high transmission efficiency is ensured while the safe charging is realized; according to the system, the service life of the transmitting coil is prolonged, the charging device is convenient to maintain, in addition, foreign matter is directly removed through the attached structure, an additional foreign matter detection device is not needed, and the efficiency and safety in the wireless charging process of the electric vehicle are improved.

    本发明公开了一种电动汽车无线充电方法及充电系统,所述方法包括以下步骤:将发射线圈与车辆内接收线圈进行对位后移动发射线圈,使得发射线圈向车辆内接收线圈移动;当发射线圈移动至预设距离后,车辆开始充电;车辆充电完成后,发射线圈开始远离接收线圈,停止充电。本发明的系统包括对位装置、充电装置和控制系统。本发明的方法可实现对无线充电发射端的轻量化,在安全充电的同时保证高传输效率;本发明的系统增加了发射线圈的使用寿命,便于充电装置维护,此外贴合式结构还直接排除了异物,不需要额外的异物检测装置,提高了电动汽车无线充电过程中的效率和安全性。
