The invention relates to an electric vehicle wireless charging system based on a microgrid, which belongs to the technical field of wireless charging. The system comprises a microgrid system, a high-frequency inverter circuit, a transceiving coil, a rectifying circuit, a direct-current chopper circuit and a vehicle-mounted battery. The microgrid is used for charging the electric vehicle through the magnetic resonance type wireless electric energy transmission system. The wireless charging system is used for transmitting electric energy generated by photovoltaics to an electric vehicle in a charging area in a magnetic coupling resonance mode. On the basis that basic charging is completed, collected light energy can be fully utilized, the collected light energy is applied to the electric vehicle through wireless electric energy transmission in a high-efficiency mode, and energy expenditure is saved for users of the electric vehicle.
