The invention discloses an electric vehicle dynamic wireless charging system with self-adaptive charging power and a control method, and belongs to the technical field of magnetic coupling wireless electric energy transmission. Coils and communication circuits are arranged at a ground end and a vehicle-mounted end of the system, and an information channel between the ground end and a vehicle end is established; the vehicle can transmit own information such as the power level, the vehicle ID, the battery state and the like to the ground end, and a device at the ground end can perform corresponding control and adjustment according to the information, so that multi-power-level charging of the device is realized to be matched with charging required power of electric vehicles of different models, and the charging efficiency is improved. And meanwhile, the charging power of the device at the ground end can be adjusted according to the existing electric quantity of the electric vehicle, and the storage battery can be protected while the charging efficiency is guaranteed.

    本发明公开了自适应充电功率的电动汽车动态无线充电系统及控制方法,属于磁耦合无线电能传输技术领域,该系统在地面端和车载端设置线圈与通讯电路,通过建立地面端与车端的信息通道,当电动汽车进入充电导轨区域,车辆可以将自身的信息如:功率等级、车辆ID、电池状态等,传递给地面端,地面端的装置可以根据该信息进行相应的控制、调整,从而实现装置的多功率等级充电,以匹配不同型号的电动汽车充电需求功率,同时还可以根据电动汽车已有的电量调节地面端的装置的充电功率,在保证充电效率的同时还可以对蓄电池进行保护。
