Abstract

Provided is a power receiving apparatus including: a contact power receiving unit configured to receive power with use of a wired transfer path via a connecting terminal; a contactless power receiving unit configured to receive power with use of a wireless transfer path via contactless coupling with a power supply apparatus; and a control unit configured to determine whether or not power is receivable by the contact power receiving unit and the contactless power receiving unit to control charging of power supply. According to the above embodiment, in a case where power is receivable by both the contactless power receiving unit and the contact power receiving unit, the control unit controls a rechargeable battery to be allowed to be charged with power received by the contact power receiving unit, and communication with the power supply apparatus to be allowed via the contactless coupling with the power supply apparatus.
