The present invention discloses a control method for a wireless charging system. The method comprises the steps of (S1) changing a switching state of a circuit breaker, thereby changing the circuit topology types of a non-control primary side rectifying unit (1) and a secondary side rectifying unit (5) of the wireless charging system, and simulating an interoperability scenario in the actual application of the wireless charging system, (S2) obtaining an interoperation result of the non-control primary side rectifying unit (1) and the secondary side rectifying unit (5) according to the simulated n interoperability scenario, and (3) analyzing the interoperation result and determining a topology circuit with best interoperability of the non-control primary side rectifying unit (1) and the secondary side rectifying unit (5). Therefore, the interoperability of each topology type of wireless charging primary and secondary sides is analyzed, advice is given to equipment produced by a manufacturer, the interconnection between different charging equipment is ensured, and therefore, the popularization and application of the wireless charging technology are promoted.
