Abstract

A power transmitting apparatus, which simultaneously or sequentially supplies electric power to a plurality of power receiving apparatuses in a wireless manner, includes a power transmitting unit configured to transmit electric power to the plurality of power receiving apparatuses, a reception unit configured to receive a power transmission end request and an abnormality content regarding power transmission from a first power receiving apparatus from among the plurality of power receiving apparatuses, and a power transmission determination unit configured, based on the abnormality content, to determine whether to stop power transmission to power receiving apparatuses that have not completed power transmission and that are not the first power receiving apparatus from among the plurality of power receiving apparatuses.

Claims (18)

1. A power supplying apparatus comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the power supplying apparatus to execute steps of:

supplying power wirelessly to one or more power receiving apparatuses including a first power receiving apparatus, wherein power is not supplied to a second power receiving apparatus while power is supplied to the first power receiving apparatus;

receiving a notification from the first power receiving apparatus;

controlling the power supplying apparatus to change a supply destination of the power being supplied to the first power receiving apparatus, from the first power receiving apparatus to the second power receiving apparatus, in response to the received notification, in a case where the received notification is related to an error of power supply and history information indicating a number of times of the error indicates a number which is smaller than or equal to a predetermined number; and

controlling to stop supplying power to all of the power receiving apparatuses which are receiving power supply from the power supplying apparatus, in response to the received notification, in a case where the received notification indicates a an error of power supply and the history information indicating the number of times of the error indicates a number which is larger than the predetermined number.

2. The power supplying apparatus according to claim 1 , wherein the error is an overvoltage or an overcurrent.

3. The power supplying apparatus according to claim 1 , wherein the received notification indicates completion of charging.

4. The power supplying apparatus according to claim 3 , wherein the error is an overvoltage or an overcurrent.

5. A method for controlling a power supplying apparatus, the method comprising:

supplying power wirelessly to one or more power receiving apparatuses including a first power receiving apparatus, wherein the power supplying apparatus does not supply power to a second power receiving apparatus while the power supplying apparatus supplies power to the first power receiving apparatus;

receiving a notification from the first power receiving apparatus; and controlling the power supplying apparatus to change a supply destination of the power being supplied to the first power receiving apparatus, from the first power receiving apparatus to the second power receiving apparatus, in response to the received notification, in a case where the received notification is related to an error of power supply and history information indicating a number of times of the error indicates a number which is smaller than or equal to a predetermined number; and

controlling the power supplying apparatus to stop supplying power to all of the power receiving apparatuses which are receiving power supply from the power supplying apparatus, in response to the received notification, in a case where the received notification indicates an error of power supply and the history information indicating the number of times of the error indicates a number which is larger than the predetermined number.

6. A non-transitory computer-readable storage medium storing computer executable instructions that, when executed, cause an apparatus to execute a process for supplying power, the process comprising:

supplying power wirelessly to one or more power receiving apparatuses including a first power receiving apparatus, wherein the power supplying apparatus does not supply power to a second power receiving apparatus while the power supplying apparatus supplies power to the first power receiving apparatus;

receiving a notification from the first power receiving apparatus; and controlling the power supplying apparatus to change a supply destination of the power being supplied to the first power receiving apparatus, from the first power receiving apparatus to the second power receiving apparatus, in response to the received notification, in a case where the received notification is related to an error of power supply and history information indicating a number of times of the error indicates a number which is smaller than or equal to a predetermined number; and

controlling the power supplying apparatus to stop supplying power to all of the power receiving apparatuses which are receiving power supply from the power supplying apparatus, in response to the received notification, in a case where the received notification indicates an error of power supply and the history information indicating the number of times of the error indicates a number which is larger than the predetermined number.
