WIRELESS CHARGING METHOD FOR URBAN AIR MOBILITY AND DEVICE AND SYSTEM THEREFOR

The present disclosure relates to an in-place alignment method for wireless charging of an urban air mobility and a device and a system therefor. A wireless charging method in an urban air mobility includes acquiring location information of a supply device for supplying wireless power, moving the urban air mobility to the supply device based on the location information, sensing a sensor signal of the supply device based on a distance to the supply device becoming equal to or smaller than a first distance, performing first charging in which the urban air mobility moves to the supply device based on the sensed sensor signal, stops and performs wireless charging with first power, performing fine alignment based on a wireless charging efficiency calculated during the first charging, and performing second charging in which wireless charging with second power is performed based on completion of the fine alignment. Therefore, the present disclosure has an advantage of maximizing a wireless charging efficiency and minimizing a power waste by quickly and accurately aligning wireless power transmitting/receiving pads of the urban air mobility and the supply device with each other in place.
