Abstract

An electronic device includes a power receiving device, a reception-side power storage unit configured to store power received by the power receiving device, a drive unit configured to be activated together with the power receiving device by the power stored in the reception-side power storage unit, a notification unit configured to notify a user of a state of the power in the reception-side power storage unit, a first power measurement unit configured to measure supplied power, a second power measurement unit configured to measure power consumption, and circuitry configured to change a notification mode in the notification unit based on a relationship between the supplied power and the power consumption.

First claim

1 . An electronic device, comprising:
a power receiving device configured to receive power transmitted from a power transmitting device through contactless power supply using a power transfer signal; a reception-side power storage unit configured to store the power received by the power receiving device; a drive unit configured to be activated together with the power receiving device by the power stored in the reception-side power storage unit; a notification unit configured to notify a user of a state of the power in the reception-side power storage unit; a first power measurement unit configured to measure supplied power, the supplied power referring to power suppliable from the reception-side power storage unit to the power receiving device and the drive unit; a second power measurement unit configured to measure power consumption, the power consumption referring to power consumed by the power receiving device and the drive unit; and circuitry configured to change a notification mode in the notification unit based on a relationship between the supplied power measured by the first power measurement unit and the power consumption measured by the second power measurement unit.

2 . The electronic device according to claim 1 , wherein the supplied power includes power supplied from the power receiving device to the reception-side power storage unit.

3 . The electronic device according to claim 2 , wherein the supplied power further includes power left in the reception-side power storage unit.

4 . The electronic device according to claim 1 , wherein
the notification unit includes a sound generator configured to produce a warning sound, and the circuitry is configured to cause the sound generator to produce the warning sound on condition that the supplied power is less than the power consumption.

5 . The electronic device according to claim 4 , wherein the circuitry is configured to cause the sound generator to stop producing the warning sound when the supplied power becomes greater than or equal to the power consumption while the sound generator is producing the warning sound.

6 . The electronic device according to claim 1 , wherein
the notification unit includes an indicator configured to be shown in a first display mode and a second display mode, and the circuitry is configured to cause the indicator to be shown in the first display mode when the supplied power is less than the power consumption and cause the indicator to be shown in the second display mode when the supplied power is greater than or equal to the power consumption.
