Power transmission apparatus, method for controlling power transmission apparatus, and storage medium storing program
First Claim
1. A power transmission apparatus comprising:
- a power transmission circuit configured to perform power transmission;
a communication circuit configured to perform wireless communication; and
a control unit configured to control power transmission to a first power reception apparatus by the power transmission circuit in accordance with a result of a negotiation to establish power transmission with the first power reception apparatus using communication by the communication circuit,wherein, where a signal is received by the communication circuit from a second power reception apparatus that is different from the first power reception apparatus during the power transmission to the first power reception apparatus, the control unit is configured to determine whether to perform a negotiation to establish power transmission with the second power reception apparatus on a basis of a comparison between a predetermined value and a power reception value that is included in the signal received from the second power reception apparatus, the power reception value indicating an amount of power received by the second power reception apparatus during the power transmission to the first power reception apparatus;
wherein, where it is determined to perform the negotiation with the second power reception apparatus, the control unit causes the power transmission circuit to perform power transmission to the second power reception apparatus in accordance with the result of negotiation with the second power reception apparatus, and where it is determined not to perform the negotiation with the second power reception apparatus, the control unit determines not to perform the negotiation with the second power reception apparatus, and thereby power transmission to the second power reception apparatus by the communication circuit is restricted.

Abstract
In a case where a notification signal is received from a second power reception apparatus different from a first power reception apparatus while power transmission is performed to the first power reception apparatus, power transmission to the second power reception apparatus is performed according to a result of negotiation with the second power reception apparatus if a power reception value corresponding to information included in the notification signal received from the second power reception apparatus is a sufficient value. The second power reception apparatus is not targeted for the power transmission if the power reception value corresponding to the information included in the notification signal received from the second power reception apparatus is not a sufficient value.

13. A method for controlling a power transmission apparatus including a power transmission circuit configured to perform power transmission, the method comprising:
-
performing wireless communication using a communication circuit of the power transmission apparatus; performing power transmission to a first power reception apparatus by the power transmission circuit in accordance with a result of a negotiation to establish power transmission with the first power reception apparatus using communication by the communication circuit; and determining, where a signal is received by the communication circuit from a second power reception apparatus that is different from the first power reception apparatus during the power transmission to the first power reception apparatus, whether to perform a negotiation to establish power transmission with the second power reception apparatus on a basis of a comparison between a predetermined value and a power reception value that is included in the signal received from the second power reception apparatus, the power reception value indicating an amount of power received by the second power reception apparatus during the power transmission to the first power reception apparatus; wherein, where it is determined to perform the negotiation with the second power reception apparatus, performing power transmission to the second power reception apparatus by the power transmission circuit in accordance with the result of negotiation with the second power reception apparatus, and where it is determined not to perform the negotiation with the second power reception apparatus, determining not to perform the negotiation with the second power reception apparatus, and thereby power transmission to the second power reception apparatus by the communication circuit is restricted.

14. A non-transitory storage medium storing a program for causing a power transmission apparatus to perform a control method, the power transmission apparatus including a power transmission circuit configured to perform power transmission, the control method comprising:
-
performing wireless communication using a communication circuit of the power transmission apparatus; performing power transmission to a first power reception apparatus by the power transmission circuit in accordance with a result of a negotiation to establish power transmission with the first power reception apparatus using communication by the communication circuit; and determining, where a signal is received by the communication circuit from a second power reception apparatus that is different from the first power reception apparatus during the power transmission to the first power reception apparatus, whether to perform a negotiation to establish power transmission with the second power reception apparatus on a basis of a comparison between a predetermined value and a power reception value that is included in the signal received from the second power reception apparatus, the power reception value indicating an amount of power received by the second power reception apparatus during the power transmission to the first power reception apparatus; wherein, where it is determined to perform the negotiation with the second power reception apparatus, performing power transmission to the second power reception apparatus by the power transmission circuit in accordance with the result of negotiation with the second power reception apparatus, and where it is determined not to perform the negotiation with the second power reception apparatus, determining not to perform the negotiation with the second power reception apparatus, and thereby power transmission to the second power reception apparatus by the communication circuit is restricted.
