Power transmission apparatus, method for controlling the same, and program
First Claim
1. A power transmission apparatus comprising:
- a power transmission unit configured to wirelessly transmit power;
a detection unit configured to detect, based on first power for detection transmitted by the power transmission unit, an object present in a range of the power transmission apparatus where the power is transmitted; and
a discrimination unit configured to discriminate, based on an authentication, whether the object detected by the detection unit is a power reception apparatus to which power is to be transmitted, wherein the power transmission unit transmits, to the object, second power for the authentication,wherein the discrimination unit performs the discrimination in a case where the detection unit detects the object at each of a plurality of times of transmission of the first power, andwherein the power transmission unit transmits third power to the object which is discriminated, by the discrimination unit, to be the power reception apparatus, to which power is to be transmitted, the third power being larger than the first power and the second power.

Abstract
A power transmission apparatus includes a power transmission unit configured to wirelessly transmit power to a power reception apparatus, a detection unit configured to detect an object present in a range of the power transmission apparatus where the power is transmitted based on an intermittent power transmission, and an authentication unit configured to authenticate whether the object detected by the detection unit is the power reception apparatus that receives the power, wherein the authentication unit authenticates the object detected as being present in the range where the power is transmitted at each of a plurality of times of the power transmission for detection during a predetermined period, and wherein the power transmission unit transmits the power to the power reception apparatus that has been successfully authenticated.

10. A method for controlling a power transmission apparatus that includes a power transmission unit configured to wirelessly transmit power, the method comprising:
-
detecting, based on first power for detection transmitted by the power transmission unit, an object present in a range of the power transmission apparatus where the power is transmitted; and discriminating, based on an authentication, whether the detected object is a power reception apparatus to which power is to be transmitted, wherein the power transmission unit transmits, to the object, second power for the authentication, wherein the discriminating is performed in a case where the object is detected at each of a plurality of times of transmission of the first power, and wherein third power is transmitted to the object which is discriminated, by the discrimination unit, to be the power reception apparatus, to which power is to be transmitted, the third power being larger than the first power and the second power.

11. A non-transitory computer-readable storage medium storing computer-executable instructions for a causing a power transmission apparatus that includes a power transmission unit to execute a method to wirelessly transmit power, the method comprising:
-
detecting, based on first power for detection transmitted by the power transmission unit, an object present in a range of the power transmission apparatus where the power is transmitted; and discriminating, based on an authentication, whether the detected object is a power reception apparatus to which power is to be transmitted, wherein the power transmission unit transmits, to the object, second power for the authentication, wherein the discriminating is performed in a case where the object is detected at each of a plurality of times of transmission of the first power, and wherein third power is transmitted to the object which is discriminated, by the discrimination unit, to be the power reception apparatus, to which power is to be transmitted, the third power being larger than the first power and the second power.
