Abstract

A method and device for charging a battery is provided. A charging device transmits a charging initiation request including the meter identifier and a charging identifier to a server, and receives a charging initiation response in response to the charging initiation request from the server. The charging device transmits a charging completion message indicating power consumed for the charging to the server upon completion of the charging, and receives charging information indicating billing information according to the charging of the battery from the server.

Claims

1. A method for charging a battery, comprising:

obtaining a meter identifier for identifying an electricity meter that measures power consumed in a charging station provided with power;

transmitting a charging initiation request including the meter identifier and a charging identifier for identifying a user to a server;

receiving a charging initiation response in response to the charging initiation request from the server;

after receiving the charging initiation response, connecting the charging station with the battery to perform charging;

upon completion of the charging, transmitting a charging completion message indicating power consumed for the charging to the server, the charging completion message including the charging identifier and the meter identifier; and

receiving charging information indicating billing information according to the charging of the battery from the server.

2. The method of claim 1, wherein obtaining the meter identifier comprises:

transmitting an information request requesting the meter identifier to the electricity meter; and

receiving an information response including the meter identifier in response to the information request from the electricity meter.

3. The method of claim 2, further comprising:

performing user authentication, wherein when the authentication is successfully complete, the charging initiation request is transmitted.

4. A charging device for charging a battery, comprising:

a first connector electrically connected to the battery;

a second connector electrically connected to a charging station to which electric power is supplied; and

a control device connected to the first and second connectors, and configured to communicate with a server using a charging identifier for identifying a user and a meter identifier for identifying the electricity meter for measuring electric power consumed by the charging station and receive billing information according to the charging of the battery from the server.

5. The charging device of claim 4, wherein the control device comprises:

a power measuring unit for measuring electric power consumed for charging the battery,

a memory for storing the charging identifier,

a transceiver for communicating with the server, and

a controller connected to the transceiver.

6. The charging device of claim 5, wherein the controller is configured to:

obtain the meter identifier;

transmit a charging initiation request including the charging identifier and the meter identifier to the server;

receive a charging initiation response in response to the charging initiation request from the server;

after receiving the charging initiation response, connect the charging station with the battery to perform charging;

upon completion of the charging, transmit a charging completion message indicating power consumed for the charging to the server, the charging completion message including the charging identifier and the meter identifier; and

receive charging information indicating the billing information from the server.

7. The charging device of claim 6, wherein the controller is configured to obtain the meter identifier by:

transmitting an information request requesting the meter identifier to the electricity meter; and

receiving an information response including the meter identifier in response to the information request from the electricity meter.

8. The charging device of claim 7, wherein the controller is configured to perform user authentication, and when the authentication is successfully complete, transmit the charging initiation request.

9. The charging device of claim 5, further comprising a switch that initiates charging by connecting or disconnecting the first connector to/from the second connector in response to a command from the controller.

10. A server comprising:

a billing DB for storing billing information for consumed power;

a transceiver for communicating with an electricity meter that measures power consumed in a charging station provided with power and a charging device for charging a battery; and

a billing for calculating unit connected to the transceiver and the billing DB, wherein the billing calculating unit is configured to;

receive a charging initiation request including a meter identifier for identifying the electricity meter and a charging identifier for identifying a user from the charging device,

transmit a charging initiation response to the charging device in response to the charging initiation request,

upon completion of the battery charging, receive a charging completion message indicating power consumed for the charging from the charging device, and

transmit charging information indicating billing information according to the battery charging to the charging device.

11. The server of claim 10, wherein the transceiver communicates with the charging device through a mobile communication network and communicates with the electricity meter through power line communication.

12. The server of claim 10, wherein the billing calculating unit is configured to exclude billing for the battery charging from the billing by the charging station.
