Abstract: The present invention relates to a wireless charging control method of a device which provides the wireless charging of the device by dividing a service into a free service and a fee service and applies fees according to the fee charging. If a receiving terminal of a device to be charged recognizes a power signal transmitted from a power transmission terminal, the present invention performs a charging mode by setting a resonant frequency of the receiving terminal as a free charging frequency or a fee charging frequency on the basis of a predetermined charging method. The present invention charges a battery of the device to be charged using a charging power signal received through the receiving terminal. The present invention provides a proper charging service according to the wireless charging of the device by performing payment when the battery is charged with the fee charging frequency.
