The invention discloses a wireless charging system, an electric vehicle, a power supply device and a charging method, and belongs to the technical field of vehicle wireless charging. The wireless charging system comprises a power supply coil, a power receiving coil, a collecting ring and an electric brush, the power supply coil is arranged in the preset moving direction of the electric vehicle, the power receiving coil is arranged on a wheel of the electric vehicle, the power receiving coil receives power from the power supply coil through electromagnetic induction, and the power receiving coil is electrically connected with a rectifying device of the electric vehicle through the collecting ring and the electric brush. And the rectifying device is connected with the energy storage device or the electric load equipment. Electromagnetic induction charging is carried out through the power supply coil and the power receiving coil, the effect of supplying power and charging while the electric vehicle runs can be achieved, the electric vehicle can run for a longer mileage in an interval road section of two charging stations, the mileage anxiety is eliminated, the capacity of energy storage equipment does not need to be increased in order to prolong the mileage, and the service life of the electric vehicle is prolonged. Therefore, the size and weight of the electric vehicle are reduced, and sustainable traffic development is promoted.

    本发明公开了无线充电系统、电动载具、供电装置和充电方法,属于载具无线充电技术领域。无线充电系统包括:供电线圈、受电线圈、集电环和电刷,供电线圈沿电动载具的预设移动方向设置,受电线圈设于电动载具的车轮,受电线圈通过电磁感应从供电线圈受电,受电线圈通过集电环和电刷电连接电动载具的整流装置,整流装置再连接储能装置或者电动负载设备。通过供电线圈和受电线圈进行电磁感应充电,可以实现电动载具边行驶边供电和边充电的效果,使得在两个充电站的间隔路段中,电动载具能够行驶更长的里程,消除了“里程焦虑”,更无须为了延长行驶里程而增加储能设备的容量,进而减轻电动载具体积和重量,推进可持续交通发展。
