The invention relates to a wireless charging method and a wireless charging device for an implantable medical device, wherein the implantable medical device comprises a wireless charge receiving module; the wireless charge receiving module comprises a receiving coil; the method comprises the following steps of: orderly driving a plurality of emitting coils in coil array, inspecting the average current value of each emitting coil; calculating the relative position of the receiving coil according to the results of inspection, and outputting an regulation information so as to conveniently regulate the position of the coil array by the user according to the regulation information, and matching an emitting coil of the plurality of emitting coils with the receiving coil. The wireless charging device comprises a coil array composed of a plurality of emitting coils, a power driving unit, a circuit inspection unit, and a main control unit. The wireless charging method and the wireless chargingdevice for an implantable medical device provided by the invention have the advantages that the position of the receiving coil can be conveniently and quickly determined by orderly driving the plurality of emitting coils in the coil array and inspecting the average current value of each emitting coil, the time for determining the position of the receiving coil is shortened, and the problem of ultra-low charging efficiency caused by inaccurate position of the receiving coil is prevented.
