The invention relates to the technical field of wireless electric energy transmission, and particularly discloses an electric vehicle wireless charging system adaptive to 11kW and 22kW receiving ends, which is based on an LCC-S topological structure, can effectively reduce the number of components of a vehicle-mounted end, reduces the weight of vehicle-mounted equipment, and meets the requirement of light weight of the vehicle-mounted end of an electric vehicle. Under the condition that the size parameters of the transmitting ends are given by the national standard, electrical parameters with interoperability are designed according to two different power levels of 11 kW and 22 kW, and the defect that one transmitting end corresponds to one receiving end in wireless charging of the electric vehicle is overcome; the parameter selection range of the compensation inductance and the system coupling coefficient of the transmitting end is given under the conditions that the two power levels of 11 kW and 22 kW meet high efficiency and the electrical stress of components is reduced, then the wireless charging system matched with the unified transmitting end is designed, and the development requirements of wireless electric vehicles are met.

    本发明涉及无线电能传输技术领域,具体公开了一种适配11kW与22kW接收端的电动汽车无线充电系统,基于LCC‑S拓扑结构,能有效减少车载端元器件数量、降低车载设备重量,满足电动汽车车载端轻量化的需求;在国标给定发射端尺寸参数下,针对11kW和22kW两个不同功率等级进行具有互操作性的电气参数设计,解决电动汽车无线充电中一个发射端对应一个接收端的弊端;给出了11kW和22kW大功率等级两个功率等级在满足高效率和减小元器件电气应力的条件下,发射端补偿电感和系统耦合系数的参数选取范围,进而设计出适配统一发射端的无线充电系统,满足无线电动汽车的发展需求。
