The invention discloses a dynamic wireless charging method and device for an electric vehicle on a photovoltaic road. The device comprises a photovoltaic road power generation system and a double-layer staggered coil. Electric energy generated by the power generation system is transmitted to a running vehicle through the magnetic coupling coil. A magnetic coupling resonance type wireless chargingtechnology is adopted, a plurality of transmitting coils and receiving coils with the same resonance frequency are used for generating resonance at a specific power supply frequency, and transmissionof wireless electric energy within a distance allowable range is achieved in a magnetic coupling resonance mode. Specifically, a transmitting coil is laid under a photovoltaic road surface, current isconverted into a magnetic field through the transmitting coil, a receiving coil is installed on avehicle chassis part, and energy transmission is conducted through resonance generated when the electromagnetic frequency of the transmitting coil is the same as that of the receiving coil. The pressure of the electric vehicle charging pile is relieved, the electric vehicle can have a longer endurancemileage under the condition that the driving time is not shortened, and meanwhile charging of the electric vehicle is safer.

    本发明公开了一种电动汽车在光伏道路上的动态无线充电方法及装置,包括光伏道路发电系统,双层错落式的线圈;通过将发电系统产生的电能经磁耦合线圈传输给行驶中的汽车。所采用的是磁耦合谐振式的无线充电技术,用多个具有相同谐振频率的发射线圈和接收线圈在特定的电源频率下产生谐振,以磁耦合谐振的方式实现距离允许范围内无线电能的传输。具体是在光伏道路路面下铺设发射线圈,利用发射线圈将电流转换为磁场,在汽车底盘部分装有接收线圈,在发射线圈与接收线圈电磁频率相同时所产生的谐振进行能量传输。本发明缓解了电动汽车充电桩的压力,而且可以让电动汽车在不压缩驾驶时间的情况下具有更长的续航里程,同时让电动汽车的充电更安全。
