Wireless charging control method and wireless charging device

The embodiment of the invention discloses a wireless charging control method. The method comprises the steps that a main control module obtains charging voltage needed by a load and recognized by a wireless charging module; the main control module judges whether the input voltage of the voltage input module is matched with the charging voltage required by the load or not through the identification circuit module, and obtains a judgment result; and the main control module controls a conversion module to convert the input voltage into output voltage according to the judgment result and transmit the output voltage to a wireless charging module, wherein the output voltage is matched with the charging voltage required by the load. The embodiment of the invention also relates to a wireless charging device. According to the embodiment of the invention, the heating value of the conversion module can be reduced, so that the overall heating value of the wireless charging device is reduced, and the charging rate of the
