Electronic device, feed unit, and feed system for reliably informing user of electronic device state during wireless electric power transmission
First Claim
1. An electronic device comprising:
- a power receiving section configured to receive electric power transmitted using a magnetic field or an electric field; and
a state informing section configured to inform a state of the electronic device, by using the electric power received by the power receiving section,wherein in an event an abnormal state is detected as the state of the electronic device, the state informing section also informs the abnormal state by using the received electric power,wherein a communication period is set in which predetermined communication with a feed unit is performed, andwherein the communication period is set to a low frequency in a period following completion of charging, as compared with a period in which a secondary battery of the electronic device is being charged.

Abstract
An electronic device includes: a power receiving section configured to receive electric power transmitted using a magnetic field or an electric field; and a state informing section configured to inform a device state of the electronic device, by using the electric power received by the power receiving section. When an abnormal state is detected as the device state, the state informing section also informs the abnormal state by using the received electric power. A feed unit includes: a power transmission section configured to perform electric power transmission using a magnetic field or an electric field, to a device to be fed; and a control section configured to continue the electric power transmission by the power transmission section, even when an abnormal state in the device to be fed is detected.

16. A feed system comprising:
-
one or a plurality of electronic devices; and a feed unit configured to perform electric power transmission using a magnetic field or an electric field, to the electronic device, wherein the electronic device includes; a power receiving section configured to receive electric power transmitted from the feed unit, and a state informing section configured to inform a state of the electronic device, by using the electric power received by the power receiving section, wherein in an event an abnormal state is detected as the state of the electronic device, the state informing section also informs the abnormal state by using the received electric power, wherein a communication period is set in which predetermined communication with the feed unit is performed, and wherein the communication period is set to a low frequency in a period following completion of charging, as compared with a period in which a secondary battery of the electronic device is being charged.
