Abstract
A communication apparatus includes communication means for performing radio communication with a partner apparatus, and supply means for wirelessly supplying power to the partner apparatus. The communication apparatus acquires information on a communication circuit for radio communication in the partner apparatus, and controls the supply means so as to determine an amount of power to be supplied per unit time depending on the information.
Claims11
A power transmission apparatus for wirelessly transmitting power to a power receiving apparatus, comprising:
- one or more memories storing instructions;
- and
- one or more processors executing the instructions for causing the power transmission apparatus to:
- obtain first information for specifying an upper limit value of power which is able to be received by a power receiving apparatus and second information for specifying power requested by the power receiving apparatus;
- determine, based on the obtained first information for specifying the upper limit value of power which is able to be received by the power receiving apparatus, whether to allow wireless power transmission with power exceeding a predetermined power value to the power receiving apparatus;
- and
- perform, based on a determination not to allow the wireless power transmission with power exceeding the predetermined power value, the wireless power transmission to the power receiving apparatus according to the requested power specified based on the obtained second information as long as the power does not exceed the predetermined power value,
- wherein the one or more processors executes the instructions for causing the power transmission apparatus to determine to allow the wireless power transmission with power exceeding the predetermined power value, based on the obtained first information including information representing that the power receiving apparatus includes a circuit that does not connect a communication circuit and a power receiving antenna during wireless power transmission.
A method for controlling a power transmission apparatus for wirelessly transmitting power to a power receiving apparatus, comprising:
- obtaining first information for specifying an upper limit value of power which is able to be received by a power receiving apparatus and second information for specifying power requested by the power receiving apparatus;
- determining, based on the obtained first information for specifying the upper limit value of power which is able to be received by the power receiving apparatus, whether to allow wireless power transmission, with power exceeding a predetermined power value to the power receiving apparatus;
- and
- performing, based on a determination not to allow the wireless power transmission with power exceeding the predetermined power value, the wireless power transmission to the power receiving apparatus according to the requested power specified based on the obtained second information as long as the power does not exceed the predetermined power value,
- wherein, determining that the wireless power transmission, with power exceeding the predetermined power value, is allowed is based on the obtained first information including information representing that the power receiving apparatus includes a circuit that does not connect a communication circuit and a power receiving antenna during wireless power transmission.
A non-transitory computer readable storage medium storing a computer program for controlling a computer to execute a method for controlling a power transmission apparatus for wirelessly transmitting power to a power receiving apparatus, comprising:
- obtaining first information for specifying an upper limit value of power which is able to be received by a power receiving apparatus and second information for specifying power requested by the power receiving apparatus;
- determining, based on the obtained first information for specifying the upper limit value of power which is able to be received by the power receiving apparatus, whether to allow wireless power transmission, with power exceeding a predetermined power value, to the power receiving apparatus;
- and
- performing, based on a determination not to allow the wireless power transmission with power exceeding the predetermined power value, the wireless power transmission to the power receiving apparatus according to the requested power specified based on the obtained second information as long as the power does not exceed the predetermined power value,
- wherein, determining that the wireless power transmission, with power exceeding the predetermined power value, is allowed is based on the obtained first information including information representing that the power receiving apparatus includes a circuit that does not connect a communication circuit and a power receiving antenna during wireless power transmission.
