wherein charging the electronic apparatus further comprises;

checking state information of the at least one of the chargeable electronic devices included in the chargeable electronic device list;

and choosing the first electronic device based on the state information of the electronic devices.

2. The method of claim 1, wherein sending the request for information regarding chargeable electronic devices comprises:

determining position information of the electronic apparatus; and

transmitting a charging information request message containing the determined position information to the server.

3. The method of claim 1, wherein charging the electronic apparatus comprises:

sending, to the at least one of the chargeable electronic devices included in the chargeable electronic device list, a request for power for wireless charging; and

receiving the requested power for wireless charging from the at least one of the chargeable electronic devices included in the chargeable electronic device list.

4. The method of claim 3, wherein charging the electronic apparatus further comprises transmitting, to the server, a result of the wireless charging.

5. The method of claim 1, wherein the state information includes information indicating whether there is permission for each corresponding electronic device to supply power to the electronic apparatus.

6. The method of claim 1, wherein the state information includes information indicating a type and a state of a power source of each of the at least one electronic device.

7. The method of claim 6, wherein the state information includes position information of each of the at least one electronic device.

8. The method of claim 3, wherein sending the request for power for wireless charging includes sending a request to each of the at least one of the chargeable electronic devices included in the chargeable electronic device list.

9. A method for managing wireless charging of an electronic apparatus performed in a server, the method comprising:

receiving, from a terminal, a request of information regarding chargeable electronic devices;

checking the information regarding chargeable electronic devices; and

transmitting, to the electronic apparatus, the checked information including a chargeable electronic device list including at least one of the chargeable electronic devices existing in an area where the electronic apparatus is located,

wherein checking the information regarding the chargeable electronic devices comprises;

determining state information of the found electronic devices; and

determining at least one chargeable electronic device to be included in the information transmitted to the electronic apparatus based on the state information of the found electronic devices.

10. The method of claim 9, wherein checking the information regarding the chargeable electronic devices comprises:

generating the chargeable electronic device list including the found electronic devices;

generating the information regarding chargeable electronic devices, which includes the chargeable electronic device list; and

transmitting the generated information regarding the chargeable electronic devices to the electronic apparatus.

11. The method of claim 9, wherein checking the information regarding chargeable electronic devices comprises searching for electronic devices that exist within a predetermined range from the electronic apparatus and can supply power to the electronic apparatus.

12. The method of claim 9, wherein determining the state information of the found electronic devices comprises:

sending, to the found electronic devices, a request for the state information; and

receiving the state information from the found electronic devices.

13. The method of claim 9, wherein the state information includes information indicating whether there is permission for each corresponding electronic device to supply power to the electronic apparatus.

14. The method of claim 9, wherein the state information includes information indicating a type and a state of a power source of each one of the found electronic devices.

15. The method of claim 14, wherein the state information includes position information of each one of the found electronic devices.

16. A method performed in an electronic device for managing a

supply of power for wireless charging of a terminal through a server, the method comprising:

receiving, from the server, a request for state information of the electronic device;

determining the state information;

transmitting the determined state information to the server;

receiving, from the terminal, a request for supplying power for wireless charging of the terminal based on information regarding chargeable electronic devices including a chargeable electronic device list including at least one of the chargeable electronic devices existing in an area where the terminal is located; and

supplying power for wireless charging of the terminal according to the received request.

17. The method of claim 16, wherein the state information includes information indicating whether there is permission for the electronic device to supply power to the terminal.

18. The method of claim 16, wherein the state information includes information indicating a type and a state of a power source of the electronic device.

19. The method of claim 16, wherein the state information includes position information of the electronic device.

23. The method of claim 17, wherein supplying the power for wireless charging of the terminal comprises exchanging information regarding a charging method and a charging frequency with the terminal and supplying the power for wireless charging based on the exchanged information.

20. A portable terminal comprising:

a wireless charging processor for receiving information including a chargeable electronic device list including at least one of the chargeable electronic devices existing in an area where the portable terminal is located through communication with a server, choosing a first electronic devices among the at least one of the chargeable electronic devices, and controlling wireless charging with power supplied by the first electronic device; and

a receiver for receiving wireless power supplied from the first electronic device and providing the received power to a battery of the portable terminal;

wherein controlling the wireless charging further comprises;

checking state information of the at least one of the chargeable electronic devices included in the chargeable electronic device list; and

choosing the first electronic device based on the state information of the electronic devices.

21. A server apparatus comprising:

a processor for checking information including a chargeable electronic device list including at least one of the chargeable electronic devices existing in an area where a terminal is located, and determining the checked information to the terminal; and

managing information regarding the terminal and at least one electronic device for wirelessly supplying power to the terminal;

wherein checking the information comprises;

determining state information of found electronic devices; and

determining the at least one chargeable electronic device to be included in the information transmitted to the terminal based on the state information of the found electronic devices, and

wherein a request of the information including the chargeable electronic device list is received from the terminal.
