Abstract

Provided are a user authenticating electrical outlet or connector by which there is no standby power consumption, a power mediating module for receiving power from the electrical outlet or connector and supplying the same to a power consuming device, and the power consuming device that is provided with the power mediating module or receives power via the power mediating module. A user authenticating electrical outlet or connector according to an embodiment of the present invention comprises: an authenticating terminal for receiving authenticating power for user authentication and a transmitted electrical outlet operating password; an authenticating device operated by the authenticating power and determining whether the electrical outlet operating password corresponds to electrical outlet ID information; and a micro-current limiting device for allowing a micro-current to flow when a power consuming device is connected to the user authenticating electrical outlet or connector. The authenticating power is obtained from the micro-current and is supplied from the outside via the authenticating terminal. When the electrical outlet operating password corresponds to the electrical outlet ID information, main power for the power consuming device is supplied from the main power supply to the outside.

Claims

1. A user authentication electrical outlet or connector which allows a main power to be supplied from a main power supply to a power demanding side when a power demanding device is authenticated through a user authentication process, the electrical outlet or connector comprising:

a microcurrent limiting device configured to allow a microcurrent to flow from the electrical outlet or connector to the power demanding side; and

an authentication device operated with an authentication power and configured to perform the user authentication process;

wherein the microcurrent limiting device is a passive element and it is not until the power demanding device is connected to the electrical outlet or connector that a closed loop is formed for the microcurrent to flow through the microcurrent limiting device so that the microcurrent is supplied to the power demanding side, and,

wherein the authentication power is generated by the power demanding side from the microcurrent supplied to the power demanding side and is supplied from the power demanding side to the electrical outlet or connector.

2. The user authentication electrical outlet or connector according to claim 1, wherein the electrical outlet or connector transmits an electrical outlet identification (ID) information to the power demanding side in response to an electrical outlet ID request signal.

3. The user authentication electrical outlet or connector according to claim 1, wherein the microcurrent flows no longer through the microcurrent limiting device when the power demanding device is disconnected from the user authentication electrical outlet or connector.

4. The user authentication electrical outlet or connector according to claim 1, wherein the authentication device determines whether or not an electrical outlet operation password received from the power demanding side corresponds to an electrical outlet identification (ID) information.

5. The user authentication electrical outlet or connector according to claim 1, wherein the maximum value of the microcurrent is tens of mA.

6. The user authentication electrical outlet or connector according to claim 1, wherein the electrical outlet or connector transmit an electrical outlet identification (ID) information to the power demanding side and provides an allowable current amount information of the electrical outlet or connector directly to the power demanding side through the electrical outlet ID information.

7. The user authentication electrical outlet or connector according to claim 1, wherein it is allowed the main power is supplied from the main power supply to the power demanding side by closing an electromagnetic switch,

the electromagnetic switch is closed by receiving a DC power from the authentication power, and

the closing of the electromagnetic switch is maintained by continuously using the DC power or by using a part of the main power which is AC power after the electromagnetic switch is closed.

8. A power mediation module through which a main power is supplied from a main power supply to a power demeaning device when the power demanding device is authenticated through a user authentication process, the power mediation module configured to:

receive a microcurrent from a user authentication electrical outlet or connector which is allowed to flow through a microcurrent limiting device of the electrical outlet or connector,

wherein the microcurrent limiting device is a passive element and it is not until the power demanding device is connected to the electrical outlet or connector that a closed loop is formed for the microcurrent to flow through the microcurrent limiting device so that the microcurrent is supplied to the power mediation module; and

generate an authentication power from the microcurrent supplied from the electrical outlet or connector and to provide the authentication power to the electrical outlet or connector for the user authentication press.

9. The power mediation module acceding to claim 8, wherein the power mediation module transmits an electrical outlet operation password corresponding to an electrical outlet identification (ID) information of the electrical outlet or connector to the electrical outlet or connector.

10. The power mediation module according to claim 8, wherein the power mediation module includes an AC/DC converter for converting the microcurrent into a direct current to generate the authentication power.

11. The power mediation module according to claim 8, wherein the power mediation module transmits a power amount information, caused by the power demanding device, to a mediation server at every unit time period.

12. The power mediation module according to claim 8, wherein the power mediation module receives an allowable current amount information of the user authentication electrical outlet or connector corresponding to an electrical outlet identification (ID) information of the user authentication electrical outlet or connector from a mediation server.

13. A power demanding device comprising the power mediation module according to claim 8.

14. A power demanding device configured to be connected to and charged by a user authentication electrical outlet or connector via the power mediation module according to claim 8.
