Abstract

The invention discloses a wireless charging receiving device, a wireless charging control method and a wireless charging system. The wireless charging receiving device comprises a secondary side resonance network which is coupled to a primary side resonance network of an external wireless charging transmitting device and transmits the AC electric energy transmitted through the coupling of the primary side resonance network, a controllable rectification adjusting circuit which is connected with the secondary side resonance network and converts the alternating current output by the secondary side resonance network into direct current, and a vehicle-mounted detection control circuit which is connected with the controlled end of the controllable rectification adjusting circuit, detects the working parameters of the vehicle-mounted side of the electric vehicle wireless charging system, and adjusts the working parameters of the controllable rectification adjusting circuit according to the detected working parameters of the vehicle-mounted side of the electric vehicle wireless charging system or according to the working parameters of the primary side. Resonance matching of the resonance network of the wireless charging receiving device can be realized, and the problem that the resonance network is in a non-resonance matching state and affects the working characteristics of the systemis solved.
