Abstract

According to one embodiment, a power transfer system includes a power transmission apparatus and a power reception apparatus. The power transmission apparatus has a power transmission module, and a first wireless communication device configured to transmit physical profile information of the power transmission apparatus. The power reception apparatus has a power reception module, a second wireless communication device configured to receive the physical profile information, and a controller. Wireless power transfer is conducted between the power transmission module and the power reception module. The controller is configured to cross-check a physical profile of a power signal of the wireless power transfer received by the power reception module with the physical profile information and identify the first wireless communication device based on a result of the cross-check.

Claims

1. A power transfer system comprising:

a power transmission apparatus including

a power transmission module, and

a first wireless communication device configured to transmit physical profile information of the power transmission apparatus; and

a power reception apparatus including

a power reception module, wherein wireless power transfer is conducted between the power transmission module and the power reception module,

a second wireless communication device configured to receive the physical profile information, and

a controller configured to cross-check a physical profile of a power signal of the wireless power transfer received by the power reception module with the physical profile information and identify the first wireless communication device based on a result of the cross-check.

2. The power transfer system according to claim 1, wherein

in the power transfer, a first period in which the power transmission module transmits the power signal and a second period in which the power transmission module stops the transmitting of the power signal are repeated, and

the physical profile includes at least one of a time length of the first period, a time length of the second period, and a ratio between the time length of the first period and the time length of the second period.

3. The power transfer system according to claim 1, wherein the physical profile includes a frequency of the power signal.

4. The power transfer system according to claim 1, wherein

the power signal includes a first amplitude and a second amplitude which are different from each other, and

the physical profile includes at least one of a time length of a third period in which the power signal takes the first amplitude, a fourth period in which the power signal takes the second amplitude, and a ratio between the third period and the fourth period.

5. The power transfer system according to claim 1, wherein the physical profile includes a fixed value unique to the power transmission apparatus, a value fluctuating based on a predetermined algorism, and a value fluctuating at random within a predetermined range.

6. A power transmission apparatus in a power transfer system, wherein

the power transfer system includes

the power transmission apparatus, and

the power reception apparatus having

a power reception module,

a second wireless communication device, and

a controller,

the power transmission apparatus comprising:

a power transmission module, wherein wireless power transfer is conducted between the power transmission module and the power reception module; and

a first wireless communication device configured to transmit physical profile information of the power transmission apparatus so that the second communication device receives the physical profile information and the controller cross-checks a physical profile of a power signal of the wireless power transfer received by the power reception module with the physical profile information and identifies the first wireless communication device based on a result of the cross-check.

7. A power reception apparatus in a power transfer system, wherein

the power transfer system includes

a power transmission apparatus having

a power transmission module, and

a first wireless communication device configured to transmit physical profile information of the power transmission apparatus, and

the power reception apparatus,

the power reception apparatus comprising:

a power reception module, wherein wireless power transfer is conducted between the power transmission module and the power reception module;

a second wireless communication device configured to receive the physical profile information, and

a controller configured to cross-check a physical profile of a power signal of the wireless power transfer received by the power reception module with the physical profile information and identify the first wireless communication device based on a result of the cross-check.
