Electric power supply system and electric power supply system for motor vehicle

Abstract

To provide for a movable electronic device a power receiving device that when charging a battery, simplifies charging of the battery from a power feeder, which is a power supply means, and does not have faults due to an external factor relating to a relay terminal, or damage of the relay terminal, that are caused by directly connecting the battery and the power feeder, and further, to provide an electronic device including the power receiving device. An antenna circuit and a booster antenna for supplying electric power are provided in a movable electronic device. The antenna circuit receives a radio signal such as an electromagnetic wave via the booster antenna, and electric power that is obtained through the receiving of the radio signal is supplied to the battery through a signal processing circuit.
