The invention discloses an electric vehicle wireless charging system based on magnetic coupling resonance, which is powered by a 220V and 50Hz alternating current power supply, and is connected with a transmitting terminal resonant capacitor and a transmitting coil through a full-bridge uncontrolled rectifying circuit, a DC-DC step-down chopper circuit and a high-frequency full-bridge inverter circuit, a receiving coil generates high-frequency induced voltage in a resonant magnetic field, and the high-frequency induced voltage is transmitted to the transmitting terminal resonant capacitor through the full-bridge uncontrolled rectifying circuit, the DC-DC step-down chopper circuit and the high-frequency full-bridge inverter circuit. The direct current is used for charging a storage battery of the electric automobile. The vehicle-mounted charger communicates with the electric energy transmitting end through the Bluetooth module, and the charging power of the battery is adjusted by controlling the output voltage of the DC-DC chopper circuit in real time.
