20. A method of controlling a wireless charging system using an ultrasonic wave, the method comprising:
-
transmitting a charging request to a power transmission device using a radio communication by an external apparatus; in response to the charging request being received from an external apparatus, determining a direction in which the external apparatus is positioned and a distance between the wireless power transmission device and the external apparatus, by a power transmission device; when a distance with the external apparatus is within a preset value, transmitting an ultrasonic signal to the external apparatus based on the direction and distance in which the external apparatus is positioned, by the power transmission device; and in response to the ultrasonic signal being received, converting the ultrasonic signal into a charging voltage as an electric signal, by the external apparatus.
