The invention relates to a wireless charging system of an electric bicycle. Comprising a transmitting end circuit used for being connected with a power supply, a transmitting end resonance coil connected with the transmitting end circuit, a receiving end resonance coil which is coupled with a magnetic field of the transmitting end resonance coil when the transmitting end resonance coil approaches, and a receiving end circuit connected with the receiving end resonance coil and used for supplying power to a battery. A transmitting end non-resonant coil used for modulating the voltage of the transmitting end is connected between the transmitting end resonant coil and the transmitting end circuit, the transmitting end non-resonant coil and the transmitting end resonant coil are jointly fixed in a coil box outside the transmitting end circuit, and the transmitting end non-resonant coil is connected to the transmitting end circuit through an extension structure. According to the invention, the voltage of the transmitting end can be conveniently modulated, so that the transmitting end can work normally when the receiving end does not work, the charging efficiency is improved, the relative separation of the coil and the circuit is realized, and the installation operation is convenient and flexible.

    本发明涉及一种电动自行车无线充电系统,包括用于接入供电电源的发射端电路、与发射端电路连接的发射端共振线圈、在发射端共振线圈靠近时与其磁场耦合的接收端共振线圈以及与接收端共振线圈连接并用于供电至电池的接收端电路,发射端共振线圈和发射端电路之间连接有用于调制发射端的电压的发射端非共振线圈,且其与发射端共振线圈共同固定于发射端电路外部的线圈箱内,发射端非共振线圈通过一延长结构连接至发射端电路。本发明便于对发射端的电压进行调制,使发射端在接收端不工作时也能正常工作,提高了充电效率,实现了线圈和电路的相对分离,安装操作方便、灵活。
