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 M 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 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;

perform authentication for a user;

when the authentication is successfully complete, obtain a meter identifier for identifying what electricity meter performs charging, the electricity meter measuring power consumed in the charging station provided with power;

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

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

after receiving the charging initiation response from the server, 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 billing information according to the charging of the battery from the server.

2. The charging device of claim 1, wherein the Control device includes a controller, the controller being 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.

3. The charging device of claim 2, 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.

4. The charging device of claim 1, wherein the control device comprises:

a power measuring unit for measuring electric power consumed fur charging the battery;

a memory for storing the charging identifier;

a transceiver for communicating with the server; and

a controller connected to the transceiver.
