Wireless power transmission device and control method of the same
First Claim
1. A control method of a wireless power transmission device that performs wireless power transfer, comprising:
- the power transmission deviceallocating 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.

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.
