Abstract

A wireless power transceiver for wirelessly charging a battery of a portable terminal may include a body having a storage space, a power receiving module stored in the body and receiving power wirelessly from an exterior in a preset scheme to charge the battery, and a power transmitting module stored in the body and transmitting power wirelessly from the battery to an exterior in a preset scheme.

Claims

1. A wireless power transceiver for wirelessly charging a battery of a portable terminal, the wireless power transceiver comprising:

a body having a storage space;

a power receiving module stored in the body and receiving power wirelessly from an exterior to charge the battery; and

a power transmitting module stored in the body and transmitting power wirelessly from the battery to an exterior.

2. The wireless power transceiver of claim 1, further comprising a controlling unit controlling operations of the power receiving module and the power transmitting module according to battery power state information.

3. The wireless power transceiver of claim 2, wherein the controlling unit selects the operation of the power receiving module and the operation of the power transmitting module according to a power level of the battery.

4. The wireless power transceiver of claim 2, wherein the controlling unit selects charging the battery with power supplied from an exterior in a wired manner or wirelessly transmitting the power charged in the battery in the wired manner to the exterior.

5. The wireless power transceiver of claim 1, wherein the body is a case cover opening or closing a storage part in which the battery is stored in the portable terminal.

6. The wireless power transceiver of claim 5, wherein the case cover includes:

a first storage space in which the power receiving module is stored; and

a second storage space in which the power transmitting module is stored.

7. The wireless power transceiver of claim 1, wherein the power receiving module includes a power receiving controlling unit controlling power reception, and a power receiving coil receiving power from an exterior, and

the power transmitting module includes a power transmitting controlling unit controlling power transmission and a power transmitting coil transmitting power to the exterior according to a control of the power transmitting controlling unit.

8. The wireless power transceiver of claim 1, wherein the power receiving module includes a power receiving controlling unit controlling power reception,

the power transmitting module includes a power transmitting unit controlling power transmission, and

the power receiving module and the power transmitting module wirelessly transmit and receive power by commonly using a single coil.

9. The wireless power transceiver of claim 1, wherein the power receiving module and the power transmitting module commonly use a power transmitting and receiving controlling unit controlling transmission and reception of power.

10. A portable terminal comprising:

a portable terminal body;

a battery stored in a storage part provided in the portable terminal body to provide charged power to the portable terminal body; and

a wireless power transceiver having a case cover having a storage space and opening and closing the storage part of the portable terminal body in which the battery is stored;

a power receiving module stored in the case cover and receiving power wirelessly from an exterior to charge the battery; and

a power transmitting module stored in the case cover and transmitting power wirelessly from the battery to an exterior.

11. The portable terminal of claim 10, wherein the wireless power transceiver further comprises a controlling unit controlling operations of the power receiving module and the power transmitting module according to battery power state information.

12. The portable terminal of claim 11, wherein the controlling unit selects the operation of the power receiving module and the operation of the power transmitting module according to a power level of the battery.

13. The portable terminal of claim 12, wherein the portable terminal body detects the power level of the battery to select the operation of the power receiving module and the operation of the power transmitting module.

14. The portable terminal of claim 10, wherein the portable terminal body selects charging the battery with power supplied from an exterior in a wired manner or wirelessly transmitting the power charged in the battery in the wired manner to the exterior.

15. The portable terminal of claim 10, wherein the case cover includes:

a first storage space in which the power receiving module is stored; and

a second storage space in which the power transmitting module is stored.

16. The portable terminal of claim 10, wherein the power receiving module includes a power receiving controlling unit controlling power reception, and a power receiving coil receiving power from an exterior, and

the power transmitting module includes a power transmitting controlling unit controlling power transmission and a power transmitting coil transmitting power to the exterior according to a control of the power transmitting controlling unit.

17. The portable terminal of claim 10, wherein the power receiving module includes a power receiving controlling unit controlling power reception,

the power transmitting module includes a power transmitting controlling unit controlling power transmission, and

the power receiving module and the power transmitting module wirelessly transmit and receive power by commonly using a single coil.

18. The portable terminal of claim 10, wherein the power receiving module and the power transmitting module commonly use a power transmitting and receiving controlling unit controlling transmission and reception of power.
