The invention relates to the technical field of wireless charging of an industrial mobile robot AGV, and particularly discloses an AGV magnetic coupling mechanism and a constant-current and constant-voltage switching AGV wireless charging system and method.The transmitting coil Lp of the AGV magnetic coupling mechanism comprises two DD type transmitting coils which are orthogonally overlapped and connected in series; the receiving coil comprises a secondary DD type receiving coil Ls and a secondary DD type compensation coil Lf2 which are orthogonally overlapped, the coil Lf2 is a series compensation inductor in a secondary compensation network, the coupling of the transmitting coil and the receiving coil can be ensured, the coupling of the transmitting coil and the coil Lf2 is increased, the cross coupling between the coil Lf2 and the receiving coil is effectively avoided, and the coupling efficiency of the transmitting coil and the receiving coil is improved. And the method has a relatively good anti-migration characteristic. According to the system and the method, the secondary side controller controls the mode change-over switch S1 to be switched on or off so as to switch the secondary side compensation network into the LCC type compensation network with constant current output or the S type compensation network with constant voltage output, the system and the method are more fit with a battery charging curve, and the battery is effectively protected.
