Electronic system for notifying user of battery charging state

摘要

An electronic unit includes an electricity reception section configured to receive power transmitted using one of a magnetic field and an electric field, a secondary battery configured to be charged based on a received power received by the electricity reception section, and a state notification section configured to provide notification to outside as to a state of its own unit. A charging period during which the secondary battery is charged based on the received power and a non-charging period are set in a time-divisional manner. The state notification section notifies of the unit state based on the received power in both of the charging period and the non-charging period.

1. An electronic unit, comprising:
an electricity reception section configured to receive power transmitted using one of a magnetic field and an electric field; a secondary battery configured to be charged based on a received power received by the electricity reception section; and a state notification section configured to provide notification to outside as to a state of the electronic unit, wherein a charging period during which the secondary battery is charged based on the received power and a non-charging period are set in a time-divisional manner, wherein a communication operation is performed with a power feeding unit in the non-charging period, and the communication operation is set at a lower frequency in a period after completion of charging than in the charging period of the secondary battery, and wherein the state notification section notifies of the state based on the received power in both of the charging period and the non-charging period.
