摘要

PROBLEM TO BE SOLVED: To provide a radio power supply system, a power reception device, a power transmission device and its control method, and a program that are able to receive power from the power transmission device by moving into a power reception available range even if the power reception device requesting power transmission by communication with the power transmission device cannot communicate due to being out of the power reception available range.SOLUTION: A power transmission device 10 transmits power regardless of whether a power reception device 20 is situated in a power reception available range or not if it has received a transmission request to request power transmission from the power reception device 20 (step S807); and stops transmission if it has received an end request to finish the power transmission from the power reception device 20 (step S809).
