Communication apparatus, method of controlling the same, and storage medium

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.

         20 . The power supplying apparatus according to  claim 17 ,
 wherein the information includes information on an amount of power requested by a power receiving circuit by which the partner apparatus receives the power from the supply unit, and   wherein the control unit controls the supply unit so that the amount of power per unit time in a case where the communication circuit is in a state that is not affected by the operation of the supply unit becomes the requested power amount.   
     
     
         21 . The power supplying apparatus according to  claim 16 ,
 wherein the acquisition unit acquires the information that was transmitted using the communication circuit.   
     
     
         22 . The power supplying apparatus according to  claim 16 , further comprising
 determination unit configured to determine for determining a state of the partner apparatus receiving the power supplied by the supply unit,   wherein the control unit controls the supply unit so as to stop supplying the power in a case where the determination unit determinates that the partner apparatus is in a state of not receiving the power.   
     
     
         23 . The power supplying apparatus according to  claim 22 ,
 wherein the determination unit determines the state from a characteristic of electromagnetic induction of the supply unit.   
     
     
         24 . The power supplying apparatus according to  claim 23 ,
 wherein the supply unit includes a coil, and supplies the power using the coil and a coil of the partner apparatus, and   wherein the determination unit determines the state from an amount of change per unit time of an inductance between the coil of the supply unit and the coil of the partner apparatus.   
     
     
         25 . The power supplying apparatus according to  claim 24 ,
 wherein the determination unit determines that the partner apparatus is in a state of not receiving the power in a case where an absolute value of the amount of change per unit time exceeds a predetermined value.   
     
     
         26 . The power supplying apparatus according to  claim 16 , further comprising
 communication unit configured to communicate with the partner apparatus by periodically alternately switching a communication period during which communication is performed and a non-communication period during which communication is not performed,   wherein the control unit controls the supply unit so as to supply the power during the non-communication period in synchronization with the periods.   
     
     
         27 . The power supplying apparatus according to  claim 26 ,
 wherein the acquisition unit further acquires a charging state of a secondary battery of the partner apparatus by communication during the communication period, and   wherein the control unit controls the supply unit so as to stop supplying the power in a case where the secondary battery is in a full charge state.   
     
     
         28 . The power supplying apparatus according to  claim 27 ,
 wherein the control unit controls the supply unit so as to stop supplying the power in a case where communication is disconnected during the communication period in the communication unit.
