Abstract

The invention provides a power reception device, an electronic apparatus, and power supply system. In the present invention, a power reception unit receives power transmitted from a power transmissiondevice, a secondary battery stores power transmitted from the power reception unit, and a control unit operates a first function unit by means of power transmitted from the secondary battery, supplies a second function unit with the power transmitted from the power reception unit when the secondary battery stores the power transmitted from the power reception unit, and stops supplying the secondfunction unit with the power transmitted from the power reception unit when the secondary battery does not store the power transmitted from the power reception unit. The embodiment of the present invention can be achieved as a power reception device, electronic apparatus and power supply system.

Description

technical field [0001] The invention relates to a power receiving device, electronic equipment and a power supply system. [0002] This application claims priority based on Japanese Patent Application No. 2015-203595 for which it applied in Japan on October 15, 2015, and uses the content here. Background technique [0003] With the development of wireless information technology, small electronic devices such as mobile phones are becoming popular. The electronic device is carried by the user, and power is consumed due to the use. Therefore, in order to maintain the functions of the electronic equipment, there are cases where it is urgent to perform operations for power supply. In recent years, a non-contact power feeding system capable of performing non-contact (wireless) power feeding to electronic devices without performing such an operation has attracted attention. A non-contact power supply system is also called a non-contact charging system, a non-contact power transm...
