Abstract
A power transmission device includes a communication unit that transmits a power capability information transmission request via a communication channel and receives power capability information in response to the power capability information transmission request. The power transmission device also includes a processing unit that sets a parameter based on the power capability information. Further, the power transmission device includes a power transmission unit that wirelessly transmits power using the parameter. The communication unit transmits the power capability information transmission request before the power transmission unit wirelessly transmits the power.
Claims20
A power transmission device, comprising:
- a communication unit configured to:
- transmit a request via a communication channel;
- and
- receive power capability information in response to the request;
- a processing unit configured to:
- set a parameter based on the power capability information;
- and
- calculate a plurality of power transmission efficiencies based on the power capability information;
- and
- a power transmission unit configured to wirelessly transmit power according to one of the plurality of power transmission efficiencies.
A power transmission method, comprising:
- transmitting a request via a communication channel;
- receiving power capability information in response to the request;
- setting a parameter based on the power capability information;
- calculating a plurality of power transmission efficiencies based on the power capability information;
- and
- wirelessly transmitting power according to one of the plurality of power transmission efficiencies.
A power reception device, comprising:
- a storage unit configured to store power capability information;
- a communication unit configured to:
- receive a request via a communication channel;
- transmit the power capability information in response to the request;
- and
- receive parameter information based on the power capability information;
- and
- a power reception unit configured to wirelessly receive power based on a parameter indicated by the parameter information,
- wherein the reception of the request by the communication unit is before the reception of the power by the power reception unit.
