Abstract

A system for charging an electric vehicle uses an in-cable control box (ICCB), and includes: an electrical connecting device for slow charging which supplies a vehicle with electricity, which is supplied through an RFID power socket when the electrical connecting device is connected to the RFID power socket, so as to charge the vehicle, in which the electrical connecting device collects information about electric energy used to charge the vehicle and information about a position where the vehicle is charged, in order to charge for electricity according to an electricity rate applicable to the vehicle.

Claims

1. A system for charging an electric vehicle, comprising:

a portable electrical connecting device which supplies a vehicle with electricity, which is supplied through an RFID power socket when the electrical connecting device is connected to the RFID power socket, so as to charge the vehicle,

wherein the portable electrical connecting device includes;

a charging connector unit which is connected with the vehicle;

a socket connecting unit which is electrically connected with the RFID power socket, and supplied with electricity supplied through the RFID power socket; and

a control unit which collects information about electric energy used to charge the vehicle and information about a position where the vehicle is charged, and transmits the information to a server for a charging service provider in order to charge for electricity according to an electricity rate dedicated to the vehicle; and

wherein the control unit includes;

an electric meter which measures accumulated electric energy used to charge the vehicle for a certain period of time;

a first data communication unit which collects predetermined vehicle information including a vehicle position while being operated in conjunction with a data communication unit for a vehicle which is mounted in the vehicle; and

a second data communication unit which transmits the vehicle information collected by the first data communication unit and the information about the electric energy measured by the electric meter to the server for a charging service provider.

2. The system of claim 1, comprising:

an electric power company which charges for electricity used to charge the vehicle, based on the information about the position where the vehicle is charged and the information about the electric energy which are transmitted from the electrical connecting device for slow charging.

3. The system of claim 1, wherein using a server of a charging service provider, the electrical connecting device transmits the information about the position where the vehicle is charged and the information about the electric energy to the electric power company which charges for electricity used to charge the vehicle.

4. The system of claim 1, wherein an RFID card, which is used to verify an operation of charging the vehicle when the electrical connecting device is connected to the RFID power socket, is installed in the electrical connecting device, and an RFID recognition device, which is used to distinguish whether or not connection is made to charge the vehicle by reading the RFID card when the electrical connecting device is connected to the RFID power socket, is installed in the RFID power socket.

9. The system of claim 1, wherein the RFID power socket is formed by installing an RFID recognition device to a general power socket that is installed in an existing house or building, and distinguishes, using the RFID recognition device, whether an object connected to the RFID power socket is an electric vehicle or general electric device.

5. A system for charging an electric vehicle, comprising:

a portable electrical connecting device which supplies a vehicle with electricity, which is supplied through an RFID power socket when the portable electrical connecting device is connected to the RFID power socket, so as to charge the vehicle, the electrical connecting device configured to collect information about electric energy used to charge the vehicle and information about a position where the vehicle is charged, in order to charge for electricity according to an electricity rate dedicated for the vehicle,
