In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The present invention relates to a charging device for charging an electric vehicle using an infrastructure device installed in a public telephone facility without installing an additional separate base device for charging an electric vehicle in a public telephone facility installed in a space accessible to an electric vehicle And converts the charging charge of the electric vehicle into a calling charge of the public telephone, and then, the charging service is provided through the public telephone facility.

FIG. 1 is a conceptual diagram for charging an electric vehicle using a public telephone facility. In FIG. 1, the charging of the electric vehicle 10 is performed by using a general public telephone set 100 installed in a space accessible to the electric vehicle 10, .

To this end, the public telephone facility 100 is provided with a charging port 211 through which the charging cable 15 of the electric vehicle 10 is connected. The concept of charging an electric car using such a public telephone facility is described in The main feature that the present invention is distinguished from the already known technology is that it performs charging from charge of the electric vehicle 10 to payment of the charge charge by utilizing various devices basically provided in the public telephone facility 100 . In order to achieve the above object, according to the present invention, charging charges for charging an electric vehicle are converted into paying charges of a pay phone, so that charging can be performed from charging the electric vehicle to paying the charged amount using the existing pay phone system itself I suggest a plan.

A system for providing an electric vehicle charging service using a public telephone system according to the present invention will be described in detail with reference to specific embodiments.

FIG. 2 shows a configuration diagram of a first embodiment of an electric vehicle charging service providing system using a public telephone system according to the present invention.

In the first embodiment shown in FIG. 2, an electric vehicle charging apparatus 200 is provided in a public telephone facility 100 installed on a road or a parking lot, and electric power is supplied to the electric vehicle 10 through the electric vehicle charging apparatus 200 And the user 50 pays the charge for the charge to the communication company 300 at the CDR-based call charge. In FIG. 2, the communication company 300 is shown in FIG. 2. However, the server 300 may be a server of a communication company. The process of converting the charging charge into the CDR- Or the charging information may be provided to the communication company 300 so that the communication company 300 converts the charging charge into the CDR-based charging rate, and transmits the converted charging rate to the public telephone And may be paid from the user 50 through the facility 100.

Then, the communication company 300 may settle the electric power charges corresponding to the charging electric power supply to the electric power company 400 from the paid communication charge.

3 is a block diagram of an embodiment of an electric vehicle charging apparatus in an electric vehicle charging service providing system using a public telephone system according to the present invention.

The electric vehicle charging apparatus 200 may include a charging power supply unit 210, a charge management unit 230, and a communication unit 250.

Here, the charging power supply unit 210 supplies the charging power to the electric vehicle 10 connected to the public telephone set 100 and measures the supplied power. The charging power supply unit 210 measures the power supplied to the charging power supply unit 210 shown in FIG. The charging power supply unit 210 includes a charging port 211 to which the charging cable of the electric vehicle 10 is connected and a power meter 215 for measuring the charging power supplied through the charging port 215, And the charging port 211 may need to be newly installed in the public telephone facility according to the charging cable standard of the electric car 10. The power meter 215 may be a conventional power meter provided in a public telephone facility It can also be used.
