Abstract

An electronic device and a method for controlling transmission/reception of wireless power by the electronic device are provided. The method includes sensing at least one external electronic device, selecting at least one wireless power transmission/reception conductive pattern element corresponding to the sensed at least one external electronic device, and transmitting/receiving wireless power to/from the sensed at least one external electronic device by using the selected at least one wireless power transmission/reception conductive pattern element.

Claims

1. A method for controlling wireless power charging by an electronic device, the method comprising:

detecting at least one electronic device;

identifying at least one wireless coil pattern corresponding to the at least one electronic device from among a plurality of wireless coil patterns included in a display of the electronic device; and

controlling wireless power charging of the at least one electronic device based on the at least one wireless coil pattern.

2. The method as claimed in claim 1, wherein controlling the wireless power charging display comprises displaying placement information corresponding to the at least one wireless coil pattern on the display.

3. The method as claimed in claim 2, wherein controlling the wireless power charging further comprises identifying whether the at least one electronic device is placed on a first area corresponding to the placement information.

4. The method as claimed in claim 2, wherein the placement information comprises coordinate information at which the at least one electronic device is to be placed.

5. The method as claimed in claim 3, further comprising, when the at least one electronic device is identified as being placed on the first area, displaying, on a second area of the display, an item corresponding to at least one function provided by the electronic device, the second area being different from the first area.

6. The method as claimed in claim 3, further comprising, when the at least one electronic device is identified as being placed on the first area, displaying information indicating that the at least one electronic device is being charged.

7. The method as claimed in claim 3, further comprising, when the at least one electronic device is identified as not being placed on the first area, displaying guide information for the first area.

8. The method as claimed in claim 1, wherein detecting the at least one electronic device comprises:

detecting the at least one electronic device based on receiving a signal from the at least one electronic device; and

identifying placement of the at least one electronic device on the display.

9. The method as claimed in claim 1, further comprising determining information of the at least one electronic device.

10. The method as claimed in claim 1, wherein controlling the wireless power charging comprises:

activating the at least one wireless coil pattern; and

deactivating, from among the plurality of wireless coil patterns, remaining wireless coil patterns, which are different from the at least one wireless coil pattern.

11. The method as claimed in claim 1, wherein controlling the wireless power charging comprises wirelessly transmitting power to the at least one electronic device from the electronic device, or wirelessly receiving power from the at least one electronic device.

12. The method as claimed in claim 1, wherein, when the at least one electronic device includes at least two devices, the at least one wireless coil pattern includes a first pattern corresponding to a first device of the at least two devices and a second pattern corresponding to a second device of the at least two devices.

13. An electronic device for controlling wireless power charging, the electronic device comprising:

at least one sensor;

a display;

at least one processor; and

a memory configured to store instructions which, when executed by the at least one processor, cause the at least one processor to perform operations including;

detecting at least one electronic device,

identifying at least one wireless coil pattern corresponding to the at least one electronic device from among a plurality of wireless coil patterns included in the display, and

controlling wireless power charging of the at least one electronic device based on the at least one wireless coil pattern.

14. The electronic device of claim 13, wherein the at least one processor is further configured to display placement information corresponding to the at least one wireless coil pattern on the display.

15. The electronic device of claim 14, wherein the at least one processor is further configured to identify whether the at least one electronic device is placed on a first area corresponding to the placement information.

16. The electronic device of claim 15, wherein the as least one processor is further configured to:

activate coil pattern, and

deactivate, from among the plurality of wireless coil patterns, remaining wireless coil patterns, which are different from the at least one wireless coil pattern.

17. The electronic device of claim 15, wherein, when the at least one electronic device is identified as being placed on the first area, the at least one processor is further configured to display an item corresponding to at least one function provided by the electronic device on a second area of the display, the second area being different from the first area, and

wherein, when the at least one electronic device is identified as not being placed on the first area, the at least one processor is further configured to display guide information for the first area.

18. The electronic device of claim 13, wherein the at least one processor is further configured to wirelessly transmit power to the at least one electronic device, or wirelessly receive power from the at least one electronic device.

19. The electronic device of claim 13, wherein, when the at least one electronic device includes at least two devices, the at least one wireless coil pattern includes a first pattern corresponding to a first device of the at least two devices and a second pattern corresponding to a second device of the at least two devices.

20. A non-transitory computer-readable storage medium storing instructions which, when executed by the at least one processor of an electronic device, cause the at least one processor to perform a method for controlling wireless power charging, the method comprising:

detecting at least one electronic device;

identifying at least one wireless coil pattern corresponding to the at least one electronic device from among a plurality of wireless coil patterns included in a display of the electronic device; and

controlling wireless power charging of the at least one electronic device based on the at least one wireless coil pattern.
