4 is a flowchart illustrating a charging charging method by a power charging device for a plug-in electric vehicle according to an exemplary embodiment of the present invention. First, the charging and charging process will be described with reference to FIG. 4.

A user of a plug-in electric car parks a car in one of a plurality of parking lots provided in a public parking lot such as an apartment parking lot, and then selects a corresponding parking lot among the plurality of plugs 100-1, 100-2, ..., 100-N. The charging terminal of the plug-in electric vehicle is connected to the plug disposed in the terminal, and a charging command is input through the user input unit 310 of the power control device 300. For example, the charging function can be selected by operating the function selection button 302.

The control unit 330 of the power control device 300 recognizes when a charging command is input from the user input unit 310 (S501), and requests to input identification information through the display window 304 of the status display unit 350. (S503).

After the user confirms the request for inputting the identification information through the display window 304 of the status display unit 350, the user may input his or her identification information in one of several ways. In the case where the current parking lot is an apartment parking lot, residential information, that is, lake number information or resident registration number information may be input through the numeric keypad 301. Alternatively, a credit card information, a debit card information, a traffic card degree, or the like may be input by inserting a card through the card insertion hole 305, or phone number information may be input through the recognition window 303. The identification information input as described above is provided to the controller 330 by the user input unit 310 or the charging target information recognition unit 320.

The control unit 330 of the power control device 300 recognizes the identification information and stores it in the information storage unit 340 (S505), and inputs authentication information through the display window 304 of the status display unit 350. Request (S507).

After the user confirms the request for inputting the authentication information through the display window 304 of the status display unit 350, the user inputs the authentication information set in advance through the user input unit 310. For example, authentication information such as a password that can be stored in the information storage unit 340 after being input through the user input unit 310 by a prior authentication information setting process is input.

The control unit 330 of the power control device 300 compares the authentication information stored in the information storage unit 340 with the authentication information input during the authentication procedure, and processes the authentication information as normal authentication. It determines with an authentication error (S509).

If authentication is normally performed, the control unit 330 of the power control device 300 provides a control signal for controlling a relay corresponding to a plug currently requested to be charged among the relays of the relay unit 210 constituting the power relay device 200. It generates and transmits the control signal to the power relay device 200 through the transceiver 360. At this time, the control signal for integrating the amount of power is also transmitted (S511).

Among the plurality of relays constituting the relay unit 210 of the power relay device 200, a relay corresponding to a plug currently requested to be charged is interrupted, that is, in a conductive state by a control signal of the power control device 300, and connected to the corresponding plug. Supply power to the charging terminal of the plug-in electric vehicle. At this time, the corresponding integrated power meter of the power integration unit 220 accumulates the amount of power consumed by the charging.

When the plug-in electric vehicle is fully charged and charging is automatically terminated (S513), or when the user requests termination of charging through the user input unit 310 (S515), the corresponding relay, which is in a conductive state, is changed to a blocked state so that the plug-in electric vehicle is changed. Power that was supplied through the charging terminal of the power is cut off, the power relay device 200 transmits the integration information of the amount of power by the power integration unit 220 to the power control device 300 (S517).

When the control unit 330 of the power control device 300 receives the integration information of the amount of power through the transmission and reception unit 360, the control unit 330 receives the input in step S505 and stores the identification information, the charging target information, and the amount of power stored in the information storage unit 340.

The charging device 400 performs charging processing for each parking lot, that is, for each plug, by using the charging processing information provided from the power control device 300. In this case, billing processing may be performed using residence information, social security number information, credit card number information, debit card number information, and phone number information. For example, if the apartment lake information is used as residence information, the billing process may be performed by adding the bill to the monthly electricity bill of the apartment lake. Alternatively, in the case of using credit card number information or debit card number information, the billing process may be performed by adding up the monthly use price of the card. Alternatively, if the phone number information is used, the billing process may be performed by adding up the monthly communication fee of the corresponding phone number.

When a control signal for controlling a specific relay of the relay unit 210 is generated in the power control device 300 and provided to the power relay device 200, the power relay device 200 based on a control signal for controlling a specific relay. By recognizing the charging command (S601), a plug connected to the plug-in electric vehicle is determined from among the plurality of plugs 100-1, 100-2, ..., 100-N (S603).

The relay unit 210 of the power relay device 200 supplies the power through the corresponding plug by changing the relay to the conductive state (S605), and the power integrating unit 220 integrates the plug corresponding to the power supply. The amount of power consumed by charging is integrated using the power meter (S607).

When the plug-in electric vehicle is fully charged (S609) or when the user requests termination of charging through the user input unit 310 (S611), the corresponding relay, which is in the conductive state, is changed to a blocking state and the charging terminal of the plug-in electric vehicle is changed. Shut off the power supply (S613). In this case, the determining of the completion of charging in step S609 may determine that the charging of the plug-in electric vehicle is completed when the power supply through the plug does not occur for a preset time.

Finally, the power relay device 200 transmits the integration information of the amount of power by the power integration unit 220 to the power supply control device 300 to be used for the charging process (S615).

The charging method for charging power of a plug-in electric vehicle according to the present invention can be created by a computer program. The code and code segments that make up this computer program can be easily deduced by a computer programmer in the field. In addition, the computer program is stored in a computer readable media, and read and executed by a computer, thereby implementing a charging method for power supply of a plug-in electric vehicle.
