The invention discloses a wireless charging method and system for an electric vehicle, and relates to the technical field of electric vehicles, and the method comprises the steps: receiving a charging request sent by the electric vehicle after the electric vehicle is parked into a preset range from a power supply; controlling a laser transmitter to transmit a laser beam to a laser receiver, and performing communication interaction with the laser receiver through a communication module to obtain position data between the laser transmitter and the laser receiver; according to the position data, laser parameters of a laser beam emitted by the laser emitter are adjusted, so that the laser beam is aligned with the laser receiver; and when the laser receiver receives the laser beam, the laser beam is converted into electric energy, and the power supply is switched on, so that the power supply establishes a magnetic coupling resonance circuit between the laser transmitter and the laser receiver, and wireless charging of the electric vehicle is realized. According to the invention, the technical problem of low wireless charging efficiency caused by the fact that magnetic resonance or microwave wireless charging in the prior art is easily influenced by weather or obstacles can be solved.

    本发明公开了一种电动汽车无线充电方法及系统,涉及电动汽车技术领域,该方法包括:泊车进入距离供电电源的预设范围后,接收电动汽车发送的充电请求;控制激光发射器向激光接收器发射激光束,并通过通信模块与激光接收器进行通信交互,以获取激光发射器与激光接收器之间的位置数据;根据位置数据,调节激光发射器发射的激光束的激光参数,以使激光束对准激光接收器;当激光接收器接收到激光束时,将激光束转化为电能,导通供电电源,以使得供电电源通过在激光发射器和激光接收器之间建立磁耦合谐振回路,实现对电动汽车的无线充电,本发明能够解决现有技术中磁共振或微波的无线充电易受天气或者障碍物的影响,导致无线充电效率低下的技术问题。
