Description

전력선 통신을 이용한 전기차 충전 시스템{CHARGING SYSTEM FOR AN ELECTRIC CAR USING POWER LINE COMMUNICATION}TECHNICAL FIELD [0001] The present invention relates to an electric vehicle charging system using power line communication,

본 발명은 전기차 충전 시스템에 관한 것으로서, 더욱 상세하게는, 전기차의 충전 인증을 통한 전기차 충전 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle charging system, and more particularly, to an electric vehicle charging system by charging authentication of an electric vehicle.

전기차는 엔진이 전기 모터로 대체되어 기존의 내연기관 차량과 달리 전기차 충전소나 충전 스테이션 등의 전기차를 충전하기 위한 시설 이외에도 가정이나 주차장 등에 설치된 전기 콘센트를 통해 자동차의 구동 에너지원을 손쉽게 공급받을 수 있다.Unlike conventional internal combustion engine vehicles, electric vehicles are replaced by electric motors. In addition to facilities for charging electric vehicles such as electric car charging stations and charging stations, electric vehicles installed in homes, .

이와 같은 특징으로 전기차는 전기 공급이 가능한 콘센트를 통해 장소와 시간의 제한 없이 전기차의 배터리 충전이 가능하다는 큰 장점이 있다. 그러나 가정이나 주차장 등에 설치된 콘센트를 통한 전기 충전은 RFID 태그 등의 인증을 통해서 충전하거나 인증 태그가 설치되지 않는 곳에서는 무단 충전이 되는 경우가 많다. With this feature, the electric car has a great advantage that it can charge the battery of the electric car without restriction of the place and time through the electric outlet that can supply electricity. However, electric charging through an outlet installed in a home or a parking lot is often charged through authentication of an RFID tag or unauthorized charging in a place where an authentication tag is not installed.

무단 충전을 방지하기 위하여 RFID 태그를 건물 주차장 등의 전원 콘센트에 설치하고 있으나, 건물 주차장의 모든 콘센트에 태그 설비를 일일이 설치하는 것은 충전 사업자와 건물 소유자에게 번거로운 일이 된다.To prevent unauthorized charging, the RFID tag is installed in a power outlet such as a building parking lot. However, it is troublesome for the charging company and the building owner to install the tag equipment in every outlet of the building parking lot.

따라서, 충전 사업자와 건물 소유자에게 충전 전기차를 일괄적으로 관리하고, 건물 주차장 등에서 손쉽게 차량 인증을 할 수 있는 시스템이 필요한 실정이다.Therefore, there is a need for a system capable of managing charged electric vehicles collectively to charging companies and building owners, and easily certifying vehicles in building parking lots.

도2를 참조하면, 건물이나 노상의 주차장에 구비된 복수의 콘센트(110)와 그 중 하나의 콘센트(110)에 설치된 PLC 태그 모듈(100)의 모습을 볼 수 있다. 도2에 도시한 바와 같이, 주차장에 마련된 좌측의 콘센트(110)에 하나의 PLC 태그 모듈(100)을 설치하면, 동일 배선(L)에 연결된 나머지 콘센트(110)에서도 전력선 통신을 할 수 있음을 알 수 있다. Referring to FIG. 2, a plurality of outlets 110 provided in a building or a parking lot on a hearth and a PLC tag module 100 installed in one of the outlets 110 can be seen. 2, when one PLC tag module 100 is installed in the left outlet 110 provided in the parking lot, it is possible to perform power line communication even in the remaining outlet 110 connected to the same line L Able to know.

Thus, a charging company can build a charging system capable of power line communication through a minimum scale distribution work.

전기차(200)는 통신부와 충전 제어부를 포함하여 구성되며, 전원 콘센트(110)에 의해 전원을 공급받아 내부 배터리에 전기를 충전한다. The electric vehicle 200 includes a communication unit and a charge control unit. The electric power is supplied from the power outlet 110 to charge the internal battery.

통신부는 전원 콘센트(110)에 설치된 PLC 태그 모듈(100)로부터 전력선 통신을 통해 충전 정보를 수집한다. 여기서, 충전 정보는 PLC 태그 모듈(100)이 설치된 위치 정보, 전기차(200)의 식별정보 등을 포함하는 전기차(200)의 충전 수행을 위한 정보를 폭넓게 포함할 수 있다. 통신부의 통신 방식은 전력선 통신뿐만 아니라, 다양한 유무선 통신방식으로 구현될 수 있다.The communication unit collects charge information from the PLC tag module 100 installed in the power outlet 110 through power line communication.

In addition, a charging approval request is made through the charging information collected through the PLC tag module 100, and when the charging is approved, the battery of the electric vehicle 200 is charged.

관제 서버(300)는 통신부로부터 충전 정보를 수신하고, 충전 정보를 미리 등록된 데이터와 비교하여, 충전 제공 서비스에 등록된 충전 위치 및 전기차(200)에 해당하는 경우에 충전을 승인한다. 관제 서버(300)는 전기차(200)의 통신부와 캔(CAN, Controller Area Network) 통신이나 전력선 통신을 통해 충전 정보를 송수신할 수 있다.The control server 300 receives the charging information from the communication unit, compares the charging information with the data registered in advance, approves the charging position registered in the charging providing service, and charging when it corresponds to the electric vehicle 200. [ The control server 300 can transmit and receive charge information through CAN (Controller Area Network) communication or power line communication with the communication unit of the electric vehicle 200.

또한, PLC 태그에 무선통신 모듈이 포함되는 경우에는 관제 서버(300)는 PLC 태그와 통신으로 충전 정보를 수신하고, 충전 인증 절차를 진행할 수 있다. PLC 태그 통신 모듈은 전기차(200)를 통하지 않고, 관제 서버(300)로 충전 공간의 위치, ID 식별정보를 직접 통신할 수 있다.In addition, when the wireless tag is included in the PLC tag, the control server 300 receives the charge information through communication with the PLC tag, and proceeds with the charge authentication procedure. The PLC tag communication module can directly communicate the location of the charging space and the ID identification information to the control server 300 without passing through the electric vehicle 200. [

관제 서버(300)가 PLC 태그 모듈(100)로부터 수신한 정보를 토대로 전기차(200)의 충전 인증을 승인하면 전기차(200)에 전력이 공급된다. PLC 태그 모듈(100)은 전기차(200)의 충전 제어부와 마찬가지로 충전을 제어할 수 있다. 전기차(200)의 충전이 인증되면 충전이 시작되어 배터리의 충전량을 측정하고, 관제 서버(300)와의 통신으로 전기차(200)의 충전이 수행된다. 관제 서버(300)와 PLC 태그 모듈(100)은 캔 통신이나 전력선 통신을 충전 정보를 송수신할 수 있다.When the control server 300 approves charging authentication of the electric vehicle 200 based on the information received from the PLC tag module 100, electric power is supplied to the electric vehicle 200. The PLC tag module 100 can control charging as well as the charging controller of the electric vehicle 200. When charging of the electric vehicle 200 is authenticated, charging is started to measure the charged amount of the battery, and charging of the electric vehicle 200 is performed by communication with the control server 300. The control server 300 and the PLC tag module 100 can transmit and receive charge information to the can communication or the power line communication.

이와 같이, 본 발명의 실시예에 따라 전원 콘센트에 하나의 PLC 태그 모듈(100)을 설치하면 동일 변압기의 모든 콘센트에서 태그 모듈을 이용할 수 있고, PLC 태그에 통신 모듈을 부착하여 통합 관제서버와 충전 정보를 직접 송수신하여 충전 절차를 수행할 수 있다.As described above, when one PLC tag module 100 is installed in the power outlet according to the embodiment of the present invention, the tag module can be used in all the outlets of the same transformer, and the communication module is attached to the PLC tag, Information can be directly transmitted and received to perform the charging procedure.
