摘要： 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 diagnosing a state of at least one sensor included in the urban air mobility, requesting the supply device to drive a sensor included in the supply device through wireless communication based on a result of the diagnosing, measuring a location of the supply device by sensing a sensor signal of the supply device, moving the urban air mobility to the supply device based on the measured location of the supply device, and stopping the urban air mobility, performing alignment of wireless power transmission/reception pads for wireless charging, and performing wireless charging based on completion of the 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.
