1. A power transmitting apparatus comprising:
- a power transmission unit configured to wirelessly transmit power to one or more power receiving apparatuses; and
a processor configured to function as;
a receiving unit configured to receive, from each of the one or more power receiving apparatuses, function information;
a determination unit configured to determine, based on the function information received from each of the one or more power receiving apparatuses, whether each of the one or more power receiving apparatuses has a function for internally lowering a voltage obtained through power reception; and
a control unit configured to control the power transmission unit to perform power transmission in a first manner in a case where the determination unit determines that at least one of the one or more power receiving apparatuses does not have the function for internally lowering the voltage obtained through power reception, and to control the power transmission unit to perform power transmission in a second manner that is different from the first manner in a case where the determination unit determines that all of the one or more power receiving apparatuses have the function for internally lowering the voltage obtained through power reception.

Abstract
A power transmitting apparatus that wirelessly transmits power to one or more power receiving apparatuses determines whether each of the one or more power receiving apparatuses has a function for internally lowering a voltage obtained through power reception, and controls the transmitted power so that, in a case where at least one of the one or more power receiving apparatuses does not have the function, overvoltage is not applied to the power receiving apparatus that does not have the function.

9. A power receiving apparatus that receives power wirelessly from a power transmitting apparatus, the power receiving apparatus comprising:
-
a processor configured to function as; a determination unit configured to determine, based on notification from the power transmitting apparatus, whether the power transmitting apparatus has a function for controlling power to be transmitted so that an overvoltage is not applied to the power receiving apparatus; and a control unit configured to cause a notification unit to perform notification for causing power transmission from the power transmitting apparatus to the power receiving apparatus not to be performed, in a case where the determination unit determines that the power transmitting apparatus does not have the function for controlling power to be transmitted so that the overvoltage is not applied to the power receiving apparatus and the power receiving apparatus does not have a function for internally lowering a voltage obtained through the power reception. - View Dependent Claims (10, 11, 12)

13. A control method for a power transmitting apparatus that has a power transmission unit configured to wirelessly transmits power to one or more power receiving apparatuses, the method executed by a processor of the power transmitting apparatus comprising:
-
receiving, from each of the one or more power receiving apparatuses, function information; determining, based on the function information received from each of the one or more power receiving apparatuses, whether each of the one or more power receiving apparatuses has a function for internally lowering a voltage obtained through power reception; and controlling the power transmission unit to perform power transmission in a first manner in a case where it is determined in the determining that at least one of the one or more power receiving apparatuses does not have the function for internally lowering the voltage obtained through power reception, and controlling the power transmission unit to perform power transmission in a second manner that is different from the first manner in a case where it is determined in the determining that all of the one or more power receiving apparatuses have the function for internally lowering the voltage obtained through power reception.

14. A non-transitory computer-readable storage medium storing a computer program for causing a computer in a power transmitting apparatus that has a power transmission unit configured to wirelessly transmits power to one or more power receiving apparatuses to execute:
-
receiving, from each of the one or more power receiving apparatuses, function information; determining, based on the function information received from each of the one or more power receiving apparatuses, whether each of the one or more power receiving apparatuses has a function for internally lowering a voltage obtained through power reception; and controlling the power transmission unit to perform power transmission in a first manner in a case where it is determined in the determining that at least one of the one or more power receiving apparatuses does not have the function for internally lowering the voltage obtained through power reception, and controlling the power transmission unit to perform power transmission in a second manner that is different from the first manner in a case where it is determined in the determining that all of the one or more power receiving apparatuses have the function for internally lowering the voltage obtained through power reception.
