摘要： A method for wireless power transmission includes obtaining, via a Q-value circuit, first and second voltages at respective first and second nodes of a resonance circuit. The first and second voltages are effective to determine if foreign matter is present in a space affecting wireless power transmission. The method includes controlling a switching section between the Q-value circuit and the resonance circuit such that at least a part of the electric power transmission process occurs at a different time than when the first and second voltages are obtained.

摘要： A power receiving unit includes a communication unit, a control unit, a detecting unit that performs metallic foreign matter detection, and a charge storage unit. The control unit is configured to control charging so electric power is stored in the charge storage unit for consumption by the detecting unit during Q-value measurement when the control unit receives a Q-value measurement command from the power transmitting device through the communication unit.
