WIRELESS POWER TRANSMISSION DEVICE AND CONTROL METHOD OF THE SAME
First Claim
1. A wireless power transmission device, the device allocating one of a plurality of channels to perform wireless power transfer to a power receiving device in response to a power transmission request that is transmitted from the power receiving device and that designates one or more of the plurality of the channels having different frequencies, whereinwhile performing power transfer to a first power receiving device in response to a first power transmission request that designates a plurality of the channels and that is transmitted from the first power receiving device, with allocating a first channel that is one of the designated channels, in a case where a second power transmission request that designates the first channel is received from a second power receiving device, the devicestops power transfer to the first power receiving device using the first channel,starts power transfer to the first power receiving device using a channel other than the first channel in the plurality of the channels designated by the first power receiving device;
- andstarts power transfer to the second power receiving device using the first channel.

Abstract
Performing power transfer to a plurality of power receiving devices, a power transmission device allocates one of a plurality of channels to perform wireless power transfer to a power receiving device in response to a power transmission request transmitted from the power receiving device designating one or more of the plurality of the channels having different frequencies. In a case where a power transmission request using the first channel is received from a second power receiving device, the device stops power transfer to the first power receiving device using the first channel, starts power transfer to the first power receiving device using a channel other than the first channel and starts power transfer to the second power receiving device using the first channel.

5. A control method of a wireless power transmission device that performs wireless power transfer, comprising:
-
the power transmission device allocating one of a plurality of channels to perform wireless power transfer to a power receiving device in response to a power transmission request that is transmitted from the power receiving device and that designates one or more of the plurality of the channels having different frequencies; while performing power transfer to a first power receiving device in response to a first power transmission request that designates a plurality of the channels and that is transmitted from the first power receiving device, with allocating a first channel that is one of the designated channels, in a case where a second power transmission request that designates the first channel is received from a second power receiving device, stopping power transfer to the first power receiving device using the first channel; starting power transfer to the first power receiving device using a channel other than the first channel in the plurality of the channels designated by the first power receiving device; and starting power transfer to the second power receiving device using the first channel. - View Dependent Claims (6)
