The invention discloses a two-way wireless electric energy transmission system of an electric vehicle, and relates to the technical field of wireless charging of electric vehicles. The first high-frequency conversion unit and the second high-frequency conversion unit are set to be full-bridge converters, bidirectional flow of power can be achieved, a switch is arranged on a connecting branch of the first high-frequency conversion unit and the ground end compensation network, and a switch is also arranged on a connecting branch of the second high-frequency conversion unit and the vehicle-mounted end compensation network. By controlling the on and off of the switch, the whole bidirectional wireless electric energy transmission system of the electric vehicle can transmit power with higher efficiency in a wide working range from light load to heavy load.
本发明公开一种电动汽车双向无线电能传输系统,涉及电动汽车无线充电技术领域。本发明通过将第一高频变换单元和第二高频变换单元设置为全桥变换器,能够实现功率的双向流动,并在第一高频变换单元与地面端补偿网络的连接支路上设置开关,在第二高频变换单元与车载端补偿网络的连接支路上也设置开关,通过控制开关的开闭,使得整个电动汽车双向无线电能传输系统从轻载到重载的宽工作范围均能够以较高的效率进行功率传输。
