POWER RECEPTION DEVICE, CONTROL METHOD FOR POWER RECEPTION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/112622
Kind Code:
A1
Abstract:
In the present invention: information of a transmission-power-control minimum period for performing foreign object detection using a waveform attenuation method is obtained from a power transmission device; the obtained transmission-power-control minimum period is compared with an allowable transmission-power-control maximum period of a power reception device; and if the transmission-power-control minimum period, which can be generated in the power transmission device, is longer than the allowable transmission-power-control maximum period of the power reception device, a flag is set for not executing the foreign object detection by the waveform attenuation method, and a notification that the transmission-power-control maximum period is set to zero is sent to the power transmission device.
