Power transmitting apparatus, control method for power transmitting apparatus, and recording medium storing program
First Claim
1. A power transmitting apparatus comprising:
- a power transmitting unit configured to transmit power to a plurality of power receiving apparatuses by radio;
a switching unit configured to switch an operation mode of the power transmitting apparatus, in a case where power is being transmitted to a first power receiving apparatus, between a power transmission mode in which power is transmitted by the power transmitting unit to the first power receiving apparatus in response to a signal from the first power receiving apparatus, and a detection mode in which power transmission is performed by setting an output power of the power transmitting unit to a smaller value than an output power in the power transmission mode so as to detect a second power receiving apparatus that is different from the first power receiving apparatus; and
a detection unit configured to detect a quantity of electricity generated by the second power receiving apparatus coming in proximity to the power transmitting apparatus during power transmission performed by the power transmitting unit in accordance with the output power of the power transmitting unit, whereina quantity of electricity detectable by the detection unit in the detection mode is smaller than a quantity of electricity detectable by the detection unit in the power transmission mode, andthe power transmitting apparatus detects the second power receiving apparatus on the basis of the quantity of electricity detected by the detection unit and transmits power to the second power receiving apparatus in response to a signal from the second power receiving apparatus.

Abstract
The present invention relates to improvement of usability in the case of detecting a second power receiving apparatus during transmission of power to a first power receiving apparatus.
A power transmitting apparatus includes a power transmitting unit that transmits power to a plurality of power receiving apparatuses by radio, and a switching unit that controls, in a case where power is being transmitted to a first power receiving apparatus by the power transmitting unit, a power transmission mode for transmitting power to the first power receiving apparatus, and a detection mode for detecting a second power receiving apparatus that is different from the first power receiving apparatus. The resolution for detecting the second power receiving apparatus in the detection mode is higher than the resolution for detecting the second power receiving apparatus in the power transmission mode.
