The invention relates to the technical field of wireless power transmission, and particularly discloses an electric vehicle dynamic wireless charging system and method with self-adaptive charging power, a plurality of groups of transmitting guide rails are arranged at a ground end, opening and closing coils are respectively arranged at the head and tail ends of each group of transmitting guide rails, and a first vehicle-mounted detection coil and a second vehicle-mounted detection coil are arranged at a vehicle-mounted end; in the driving process of the vehicle-mounted end, the starting coil is firstly coupled with the first vehicle-mounted detection coil, at the moment, information interaction is carried out through coupling to obtain vehicle information of the vehicle-mounted end so as to adaptively adjust the transmitting power of the group of transmitting guide rails, the requirements of different vehicle types for power are met, and adaptive adjustment of the charging power is achieved; and when the induced voltage of the starting coil reaches a first voltage threshold value, the power circuit of the group of transmitting guide rails is controlled to be started, and when the induced voltage of the closing coil reaches a second voltage threshold value, the power circuit of the group of transmitting guide rails is closed, so that different transmitting guide rails are switched, and stable charging of the electric vehicle in the running process is ensured.
本发明涉及无线电能传输技术领域,具体公开了一种自适应充电功率的电动汽车动态无线充电系统及方法,其在地面端设有多组发射导轨,并在每组发射导轨的首尾两端分别设置开启和关闭线圈,在车载端设有第一、第二车载检测线圈,在车载端的行驶过程中,开启线圈率先与第一车载检测线圈进行耦合,此时通过该耦合进行信息交互以获取车载端的车辆信息从而自适应调节该组发射导轨的发射功率,满足不同车型对功率的需求,实现充电功率自适应调节;在开启线圈的感应电压达到第一电压阈值时控制该组发射导轨的功率电路开启,在关闭线圈的感应电压达到第二电压阈值时关闭该组发射导轨的功率电路,以切换不同发射导轨,保证电动汽车在行驶过程中的稳定充电。
