Abstract

A wireless charging method includes searching one or more rechargeable electronic devices, receiving power service information from one or more searched electronic devices, determining whether the one or more searched electronic devices are rechargeable based on the received power service information, and if the one or more searched electronic devices are rechargeable, receiving power from the electronic devices.

Claims

1. A method for charging power of an electronic device comprising:

searching, by the electronic device, one or more wireless charging electronic devices which provide wireless charging and are adjacent to the electronic device requiring wireless charging;

receiving, by the electronic device, power service information from the one or more searched wireless charging electronic devices, wherein power service information includes whether one or more searched wireless charging electronic devices has battery power of at least a user-definable threshold;

determining, by the electronic device, whether the one or more searched wireless charging electronic can provide wireless charging based on the received power service information;

receiving, by the electronic device, power from one of the searched wireless charging electronic devices when the one or more searched wireless charging electronic devices are determined to be able to provide wireless charging; and

if an amount of power supplied from the one of the searched wireless charging electronic devices is less than a desired amount of power, additionally receiving power from another of the searched wireless charging electronic devices after receiving power from one of the searched wireless charging electronic devices.

2. The method of claim 1, wherein the search of the one or more wireless charging electronic devices is performed through a server.

3. The method of claim 1, wherein power service information includes information as to whether the one or more searched wireless charging electronic devices subscribe to a power charging payment system and information about an amount of power remaining in respective batteries of the one or more searched wireless charging electronic devices.

4. The method of claim 1, wherein determining whether the one or more searched wireless charging electronic devices can provide wireless charging comprises determining whether there are wireless charging electronic devices which subscribe to a power charging payment system and have power in respective batteries of the one or more searched wireless charging electronic devices.

5. The method of claim 1, wherein receiving power from the one or more wireless charging searched electronic devices comprises:

selecting all wireless charging electronic devices which subscribe to a power charging payment system among the one or more searched wireless charging electronic devices;

selecting a nearest wireless charging electronic device among the wireless charging electronic devices which subscribe to the power charging payment system; and

receiving power from the nearest wireless charging electronic device.

6. The method of claim 1, further comprising transmitting information about an amount of received power to the one or more searched wireless charging electronic devices and a server.

7. The method of claim 6, wherein fees of an electronic device requiring wireless charging and the one or more searched wireless charging electronic devices are added or discounted according to the information about the amount of received power.

13. The method of claim 1, wherein each of the one or more wireless charging electronic devices is comprised of a mobile terminal or a charging station.

14. The method of claim 13, wherein the charging station having no battery is selected manually irrespective of an adjacent distance or may be selected automatically by priority over other wireless charging electronic devices having batteries if the charging station is adjacent to the wireless charging electronic device.

15. The method of claim 2, wherein the search of the one or more wireless charging electronic devices is performed through a network and a base station.

8. An electronic device for charging power, comprising:

a power transceiver;

a communication data transceiver; and

a processor configured to;

search, through the communication data transceiver, one or more wireless charging electronic devices which provide wireless charging and are adjacent to the electronic device requiring wireless charging,

control the communication data transceiver to receive power service information from the one or more searched wireless charging electronic devices,

determine whether the one or more searched wireless charging electronic devices can provide wireless charging based on the received power service information, wherein power service information includes whether one or more searched wireless charging electronic devices has battery power of at least a user-definable threshold,

if the one or more searched wireless charging electronic devices are determined to be able to provide wireless charging, control the power transceiver to receive power from one of the searched wireless charging electronic devices, and

if an amount of power supplied from the one of the searched wireless charging electronic devices is less than a desired amount of power, control the power transceiver to additionally receive power from another of the searched wireless charging electronic devices after receiving power from one of the searched wireless charging electronic devices.

9. The electronic device of claim 8, wherein the processor searches, through a server, the one or more wireless charging electronic devices.

10. The electronic device of claim 8, wherein the processor determines whether the one or more searched wireless charging electronic devices can provide wireless charging by determining whether there are wireless charging electronic devices which subscribe to a power charging payment system and have power in respective batteries of the one or more searched wireless charging electronic devices.

11. The electronic device of claim 8, wherein the processor selects all wireless charging electronic devices which subscribe to a power charging payment system among the one or more searched wireless charging electronic devices, selects a nearest wireless charging electronic device among the wireless charging electronic devices which subscribe to the power charging payment system, and performs a control function to receive power from the nearest wireless charging electronic device.

12. The electronic device of claim 8, wherein the processor controls the communication data transceiver to transmit information about an amount of received power to the one or more searched wireless charging electronic devices and a server.

16. The electronic device of claim 8, wherein each of the one or more wireless charging electronic devices is comprised of a mobile terminal or a charging station.

17. The method of claim 16, wherein the charging station having no battery is selected manually irrespective of an adjacent distance or may be selected automatically by priority over other wireless charging electronic devices having batteries if the charging station is adjacent to the wireless charging electronic device.

18. The method of claim 9, wherein the communication data transceiver searches, through a network and base station, the one or more wireless charging electronic devices.
