Abstract

The present application relates to a wireless power supply device and wireless power transmission control in an electronic device capable of receiving wireless power. According to an embodiment of the present application, the electronic device capable of receiving wireless power comprises a communication unit which receives power information including at least one piece of electricity bill information and power demand information. Also, the electronic device comprises a wireless power receiving unit which receives wireless power wirelessly supplied from a wireless power supply device, and a power converting unit which converts the wireless power received into power that can be used in the electronic device. By using various embodiments suggested by the present application, use of power wirelessly supplied can be efficiently controlled, and accordingly, electric power can be economically and efficiently used.

Claims

1. An electronic device capable of receiving wireless power, the electronic device comprising:

a communication unit receiving power information including at least one of electricity bill information and power demand information;

a wireless power receiving unit receiving wireless power from a wireless power supplying device;

a power converting unit converting the received wireless power to power usable for the electronic device; and

a controller determining a power saving period based on the received power information and controlling such that abortion of wireless power transmission is requested to the wireless power supplying device through the communication unit during the power saving period and wireless power transmission is requested to the wireless power supplying device through the communication unit during a non-power saving period.

2. The device of claim 1, wherein the controller determines that a high-priced period determined from the electricity bill information or an over-demanding period determined from the power demand information is the power saving period.

3. The device of claim 2, wherein the high-priced period or the over-demanding period is settable by a user.

4. The device of claim 1, the electronic device further comprising a supplemental power unit supplying supplemental power, wherein the supplemental power of the supplemental power unit is used for minimum operations of the electronic device.

5. The device of claim 4, the electronic device further comprising a display unit providing a display screen, wherein the controller controls such that a user notification message is provided to one side of the display unit based on whether or not it is during the power saving period.

6. The device of claim 1, the electronic device further comprising a supplemental power storage storing supplemental power in the electronic device, wherein the supplemental power of the supplemental power storage is used for main operations of the electronic device and is rechargeable.

7. The device of claim 6, the electronic device further comprising a display unit providing a display screen, wherein the controller controls such that a user notification message is provided to one side of the display unit based on whether or not it is during the power saving period and an amount of the supplemental power.

8. The device of claim 7, wherein if a user'"'"'s wireless power transmission command or a user'"'"'s wireless power transmission abortion command is inputted after the user notification message, the controller controls such that a wireless power transmission request or a wireless power transmission abortion request is transmitted to the wireless power supplying device through the communication unit.

9. The device of claim 7, wherein the controller provides different notification messages for;

during the power saving period and sufficient supplemental power, during the power saving period and insufficient supplemental power, during a non-power saving period and sufficient supplemental power, and during a non-power saving period and insufficient supplemental power.

10. The device of claim 6, the electronic device further comprises a supplemental power assuring unit assuring the supplemental power of the supplemental power storage.

11. A wireless power transmission control method for an electronic device receiving wireless power supplied from a wireless power supplying device, the method comprising:

receiving power information including at least one of electricity bill information and power demand information;

determining a power saving period based on the received power information;

requesting abortion of wireless power transmission to the wireless power supplying device during the power saving period; and

requesting wireless power transmission to the wireless power supplying device during a non-power saving period.

12. The method of claim 11, the method further comprising providing a notification message on one side of a display unit based on the determination of the power saving period.

13. The method of claim 11, the method further comprising:

providing a notification message on one side of a display unit based on the determination of the power saving period and an amount of supplemental power rechargeable in the electronic device; and

executing one of wireless power transmission request and wireless power transmission abortion request based on the notification message.

14. A wireless power supplying device comprising:

a communication unit receiving power information including at least one of electricity bill information and power demand information;

a wireless power generator for supplying wireless power to an electronic device subject to supplying wireless power; and

a controller determining whether or not a power saving period based on the received power information,

wherein if the controller determines on the power saving period, the controller transmits information about inquiring whether the wireless power is continuously supplied to the electronic device during the power saving period and controls the wireless power generator such that wireless power is supplied to the electronic device if a command to request wireless power transmission is received from the electronic device, and

wherein if the controller determines on a non-power saving period, the controller controls the wireless power generator such that wireless power is supplied to the electronic device during the non-power saving period and controls the wireless power generator such that wireless power transmission is aborted if a command to abort wireless power transmission is received from the electronic device.

15. The method of claim 14, the wireless power supplying device further comprising a power switching means, wherein the controller controls the power switching means to supply external power to the wireless power generator.

16. A wireless power transmission method of a wireless power supplying device supplying wireless power to an electronic device, the method comprising:

receiving power information including at least one of electricity bill information and power demand information;

determining whether or not a power saving period based on the received power information;

if it is determined on the power saving period, transmitting information about inquiring whether the wireless power is continuously transmitted to the electronic device during the power saving period and supplying the wireless power to the electronic device if a command to transmit wireless power is received from the electronic device; and

if it is determined on a non-power saving period, supplying the wireless power to the electronic device during the non-power saving period, and if a command to abort wireless power transmission is received from the electronic device, aborting the wireless power transmission.
