Abstract: A portable terminal is activated when receiving verification power transmitted in a contactless manner from a charger using electromagnetic coupling between the charger and the portable terminal. The portable terminal sends an electrical signal (wakeup frame) indicating activation immediately after being activated to the charger. Reception of the wakeup frame triggers the power transmitting device to start a verification process on the power receiving device and perform a detection process for a metal foreign object. After authentication is established, the charger transmits normal power to the portable terminal.

Abstract: A primary-side controller (12) retains a reference current value corresponding to an input current measured in the previous detection cycle by an input current measurement unit (11), in a charging state. The primary-side controller (12) adds the retained reference current value and a predetermined current value, and generates a first threshold value. When the input current measured by the input current measurement unit (11) in the latest detection cycle is equal to or greater than the first threshold value, a determination is made that a foreign metal is present in the vicinity of a first coil (L1).
