Abstract

Provided is a device for transmitting wireless power. The wireless power transmitting device includes a communication unit, a power receiving unit, and a processor. The processor is configured to obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device, establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information, and control to transmit the location information to the wireless power transmitting device. The power receiving unit wirelessly receives the power from the wireless power transmitting device after the communication unit transmits the location information.

Claims

1. A device for receiving power, the device comprising:

a communication unit;

a power receiving unit; and

a processor configured to;

obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device,

establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information,

transmit, through the communication unit, the location information to the wireless power transmitting device, and

control to receive, through the power receiving unit, the power from the wireless power transmitting device after transmitting the location information.

2. The device of claim 1, wherein the tag device includes one of a near field communication (NFC) tag, a radio frequency identifier (RFID) tag, a quick response (QR) code, and a magnetic secure transmission (MST) device.

3. The device of claim 1, wherein the processor is further configured to:

charge a battery using the power, and

transmit a charge complete signal to the wireless power transmitting device when the battery is completely charged.

4. The device of claim 1, wherein the processor is further configured to:

control to access, through the communication unit, a server using the communication establishment information, and

control to transmit, through the communication unit, payment information to the server.

5. A device for transmitting a power, the device comprising:

a communication unit;

a power transmitting unit; and

a processor configured to;

receive, through the communication unit, location information associated with a wireless charging area from the wireless power receiving device, and

control to transmit, through the power transmitting unit, the power wirelessly based on the location information.

6. The device of claim 5, wherein the processor is further configured to control at least one of a phase and an amplitude of an electromagnetic wave corresponding to the power based on the location information.

7. The device of claim 5, wherein the processor is further configured to:

receive a charge complete signal from the wireless power receiving device, and

control transmission of the power based on the charge complete signal.

8. The device of claim 5, wherein the processor is further configured to:

receive payment information from the wireless power receiving device, and

control to wirelessly transmit power to the wireless power receiving device based on the payment information.

9. The device of claim 8, wherein the processor is further configured to determine an amount of power to be transmitted to the wireless power receiving device based on an amount of payment included in the payment information.

10. The device of claim 8, wherein the processor is further configured to, when the payment information includes credit card information, start a wireless power transmission to the wireless power receiving device.

11. A wireless power receiving method of a wireless power receiving device, the method comprising:

obtaining communication establishment information and location information associated with a wireless charging area from a tag device;

establishing communication with a wireless power transmitting device based on the communication establishment information;

transmitting the location information to the wireless power transmitting device; and

wirelessly receiving power from the wireless power transmitting device.

12. The wireless power receiving method of claim 11, wherein the tag device includes one of a near field communication (NFC) tag, a radio frequency identifier (RFID) tag, a quick response (QR) code, and a magnetic secure transmission (MST) device.

13. The wireless power receiving method of claim 11, further comprising:

charging a battery of the wireless power receiving device using the power; and

transmitting a charge complete signal to the wireless power transmitting device when the battery is completely charged.

14. The wireless power receiving method of claim 11, further comprising:

accessing a server using the communication establishment information; and

transmitting payment information of the wireless power receiving device to the server.

15. A wireless power transmitting method of a wireless power transmitting device, the method comprising:

receiving location information associated with a wireless charging area from a wireless power receiving device; and

wirelessly transmitting power to the wireless power receiving device based on the location information.

16. The method of claim 15, wherein the transmitting of the wireless power further comprises:

controlling at least one of a phase and an amplitude of an electromagnetic wave corresponding to the power based on the location information.

17. The method of claim 15, further comprising:

receiving a charge complete signal from the wireless power receiving device; and

controlling transmission of the power based on the charge complete signal.

18. The method of claim 15, further comprising:
