Description

차량용 급속충전 공용화장치 {Shared apparatus for rapid charging of a vehicle}[0001] The present invention relates to a rapid charging system for a vehicle,

본 발명은 차량용 충전기의 충전표준에 관계없이 충전가능한 차량용 급속충전 공용화장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a rapid charge sharing apparatus for a vehicle that can be charged regardless of a charging standard of a car charger.

급속충전표준으로는 SGS(Smart Grid Station)표준과 차데모(CHAdeMO)표준이 존재한다. 도 1은 종래의 SGS(Smart Grid Station)표준에 따른 인터페이스 회로를 도시한 회로도이다. There are Smart Grid Station (SGS) standards and CHAdeMO standards for rapid charging standards. 1 is a circuit diagram showing an interface circuit according to a conventional SGS (Smart Grid Station) standard.

도 1을 참조하면, SGS 표준은 전기자동차와 전도성 충전시스템간의 직류 충전을 위한 통신 인터페이스로서 국내 급속충전표준이다. 도 1의 점선에 도시된 바와 같이 SGS표준의 경우에는 전기자동차와 직류 충전설비 측에 커플러 연결상태 정보를 제공하기 위해 파일럿 통신회로가 구성되는데, 전기자동차의 2.7kΩ 저항을 이용하여 전기자동차를 인식할 수 있도록 구현된다.Referring to Figure 1, the SGS standard is a domestic rapid charging standard as a communication interface for direct current charging between an electric vehicle and a conductive charging system. As shown by the dotted line in Fig. 1, in the case of the SGS standard, a pilot communication circuit is constituted to provide information on the coupling state of the electric vehicle and the DC charging equipment. A 2.7 k? .

도 2는 종래의 차데모(CHAdeMO)표준에 따른 인터페이스 회로를 도시한 회로도이다. 도 2를 참조하면, 차데모 표준은 전기자동차와 급속충전시스템간의 직류 충전을 위한 통신 인터페이스로서 일본의 급속충전표준이며, 북미, 유럽에 걸쳐 차데모표준의 급속충전기가 보급되고 있다. 도 2의 점선에 도시된 바와 같이 차데모 표준의 경우에는 Charge Enable신호를 감지하도록 회로가 구성된다.2 is a circuit diagram showing an interface circuit according to the conventional Car Demo (CHAdeMO) standard. Referring to FIG. 2, the car demo standard is a Japanese rapid charging standard as a communication interface for direct current charging between an electric car and a rapid charging system, and rapid chargers of the car demo standard are spreading across North America and Europe. As shown in the dotted line in Fig. 2, in the case of the demo standard, a circuit is configured to sense the Charge Enable signal.

즉, SGS 표준의 경우에는 일정전압이 차량과 충전기 측에서 감지되면 연결되었다고 인지하나, 차데모 표준의 경우 0V전압이 감지되어야 충전준비가 되었다고 인지한다. 따라서 SGS표준을 준수한 차량의 경우는 차데모 표준을 준수한 충전기로 급속충전이 불가능하고, 차데모 표준을 준수한 차량의 경우에는 SGS 표준을 준수한 충전기로는 급속충전이 불가능하다는 문제점이 있다.In other words, SGS standard recognizes that a certain voltage is connected when it is sensed at the vehicle and charger side, but recognizes that the charge demodulation standard is ready to charge when a 0V voltage is detected. Therefore, in the case of vehicles conforming to the SGS standard, it is impossible to rapidly charge a charger conforming to the car demo standard, and in the case of a car conforming to the car demo standard, a charger conforming to the SGS standard can not be rapidly charged.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 차량용 급속충전 공용화장치에 대하여 살펴본다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

도 3은 본 발명의 일 실시예에 따른 차량용 급속충전 공용화장치를 도시한 회로도이고, 도 4는 본 발명의 일 실시예에 따른 차량용 급속충전 공용화장치를 도시한 블록도이며, 도 5는 본 발명의 일 실시예에 따른 차량용 급속충전 공용화장치 제어방법을 도시한 순서도이다. 도 3 내지 도 5를 참조하면, 차량용 급속충전 공용화장치는 충전기(140)와 연결될 시, 일단이 충전기 단자(143)와 연결되도록 구비된 저항(110);과 상기 저항(110)의 타단과 접지 사이에 연결된 제1 스위칭소자(120);와 상기 충전기 단자(143)와 접지 사이에 연결되도록 구비된 제2 스위칭소자(130)를 포함하는 공용화회로(150) 및 충전기(140)로부터 수신된 캔신호에 기반하여 상기 제1 스위칭소자(120) 또는 제2 스위칭소자(130) 중 어느 하나를 온(ON)제어하는 제어부(200)를 포함할 수 있다.FIG. 3 is a circuit diagram showing a rapid charge sharing device for a vehicle according to an embodiment of the present invention, FIG. 4 is a block diagram showing a rapid charge sharing device for a vehicle according to an embodiment of the present invention, FIG. 2 is a flowchart illustrating a method of controlling a rapid charging and sharing apparatus for a vehicle according to an embodiment of the present invention. 3 to 5, the rapid charging and discharging apparatus for a vehicle includes a resistor 110 connected to the charger terminal 143 at one end when connected to the charger 140, a resistor 110 connected to the other end of the resistor 110, A common switching circuit 150 including a first switching device 120 connected between the charger terminal 143 and the ground and a second switching device 130 connected between the charger terminal 143 and the ground, And a control unit 200 for controlling the first switching device 120 or the second switching device 130 based on a signal.

먼저, 공용화회로(150)는 SGS(Smart Grid Station)표준의 파일럿회로 구성요소인 저항(110)이 구비되고 해당 저항(110)과 접지와의 연결을 제1 스위칭소자(120)가 담당하도록 마련된다. 이를 통해 만약 SGS표준사양의 충전기(140)가 연결될 시, 제1 스위칭소자(120)와 구성에 따라 차량 측 및 충전기(140) 측에 차량과 충전기(140)가 상호연결되었다는 파일럿신호가 발생한다.First, the commonizing circuit 150 is provided with a resistor 110, which is a pilot circuit component of the SGS (Smart Grid Station) standard, and the first switching element 120 is provided for connection between the resistor 110 and the ground do. Accordingly, when the charger 140 according to the SGS standard specification is connected, a pilot signal is generated that the vehicle and the charger 140 are connected to each other on the vehicle side and the charger 140 side according to the configuration of the first switching device 120 .

또한, 공용화회로(150)는 차데모(CHAdeMO)표준의 Charge Enable회로를 구성하기 위해 제2 스위칭소자(130)를 구비하도록 마련된다. 만약 차데모 표준사양의 충전기(140)가 연결되면 제2 스위칭소자(130) 구성에 따라서 차량에서 충전기(140) 측으로 송신하는 0V전압 즉, 충전준비완료 신호를 감지할 수 있다.In addition, the commoning circuit 150 is provided with the second switching element 130 for constituting a charge enable circuit of the CHAdeMO standard. If the charger 140 of the standard demo standard is connected, it can sense a 0V voltage to be transmitted from the vehicle to the charger 140 according to the configuration of the second switching device 130, that is, the charging preparation completion signal.

여기서, 충전기 단자(143)는 충전기(140)와 차량이 연결될 시 연결상태를 판단하기 위해 차량 측 공용화회로(150)와 연결되도록 마련된 단자이다.
Here, the charger terminal 143 is a terminal connected to the vehicle-side commoning circuit 150 to determine the connection state when the charger 140 and the vehicle are connected.

본 발명의 충전기(140)는 충전표준에 따라 제1 캔신호 또는 제2 캔신호 중 어느 하나를 상기 제어부(200)로 송신할 수 있고, 제어부(200)는 충전기(140)로부터 제1 캔신호가 수신되면 제1 스위칭소자(120)를 온(ON)제어하고, 제2 캔신호가 수신되면 제2 스위칭소자(130)를 온(ON)제어할 수 있다.The charger 140 of the present invention can transmit either the first can signal or the second can signal to the control unit 200 according to the charging standard and the control unit 200 can transmit the first can signal The first switching device 120 is controlled to be ON and the second switch device 130 can be controlled to be ON when the second can signal is received.

즉, 충전기(140)는 SGS표준사양일 경우에 제1 캔신호를 제어부(200)로 송신하여 제1 스위칭소자(120)를 온(ON)제어함으로써 차량과 충전기(140)가 일정전압의 파일럿신호를 인가받을 수 있도록 구성된다. 반대로, 충전기(140)가 차데모표준사양일 경우에 제2 캔신호를 제어부(200)로 송신하여 제2 스위칭소자(130)를 온(ON)제어함으로써 충전기(140)가 0V전압을 감지하여 차량과 연결되었음을 인식할 수 있도록 구성된다. 따라서, 충전기(140)의 급속충전 표준사양에 관계없이 충전을 수행할 수 있다.That is, when the SGS standard specification, the charger 140 transmits the first can signal to the controller 200 to turn on the first switching device 120 so that the vehicle and the charger 140 can receive the pilot signal So that a signal can be received. On the other hand, when the charger 140 is the standard demo standard, the second can signal is transmitted to the control unit 200 to turn on the second switching device 130 so that the charger 140 senses the 0V voltage And is configured to recognize that the vehicle is connected to the vehicle. Therefore, charging can be performed regardless of the rapid charging standard specification of the charger 140. [

제1 캔신호와 제2 캔신호는 충전기(140)의 종류에 따라 송신되는 캔신호의 ID로써 구분되는데, 예를 들어, 충전기(140)가 SGS표준을 준수하는 경우 송신되는 캔신호의 ID는 0x638, 0x639일 수 있다. 반대로 충전기(120)가 차데모표준을 준수하는 경우 송신되는 캔신호의 ID는 0x108, 0x109일 수 있다. 따라서, 충전초기단계인 경우, 차량측에 수신된 충전기(140)의 캔신호에 따라 ID로 급속충전기의 종류를 판별할 수 있다. 상술한 SGS표준 또는 차데모표준일 때의 캔신호 ID는 일 실시예일 뿐, 설계자에 의해 변형되어 설정될 수 있기 때문에 구체적인 ID로 한정되어서는 안 될 것이다.
The first can signal and the second can signal are classified by the ID of the can signal transmitted according to the type of the charger 140. For example, when the charger 140 complies with the SGS standard, the ID of the can signal to be transmitted is 0x638, 0x639. Conversely, if the charger 120 complies with the car demo standard, the ID of the can signal to be transmitted may be 0x108, 0x109. Accordingly, in the initial stage of charging, the type of the rapid charger can be determined by ID according to the can signal of the charger 140 received at the vehicle side. The can signal ID when the SGS standard or the demo standard described above is an embodiment, and should not be limited to a specific ID because it can be modified and set by a designer.

이때, 제어부(200)는 충전기(140)와 차량이 연결되고, 사용자에 의해 충전 스위치(미도시)가 온(ON)조작되면 배터리 관리 시스템(BMS:Battery Management System,210)이 충전기(140)로 요청신호를 송신하도록 제어할 수 있고, 충전기(140)는 배터리 관리 시스템(210)으로부터 요청신호를 수신하면 캔신호를 상기 제어부(200)로 송신할 수 있다.At this time, the control unit 200 is connected to the charger 140 and the vehicle. When the charging switch (not shown) is turned on by the user, the battery management system 210 (BMS) And the charger 140 can transmit a can signal to the controller 200 upon receiving a request signal from the battery management system 210. [

즉, 먼저 충전기(140)와 차량이 연결된 후, 사용자에 의해 충전 시작버튼이 온(ON)조작되면 차량측 배터리 관리 시스템(210)은 제1 요청신호와 제2 요청신호를 제어부(200)측으로 동시에 송신한다. That is, if the charging start button is turned on by the user after the battery charger 140 is first connected to the vehicle, the vehicle-side battery management system 210 transmits the first request signal and the second request signal to the control unit 200 side And transmits them simultaneously.

제1 요청신호는 충전기(140)가 SGS표준인 경우에 충전기(140)의 제1 캔신호를 요청하는 캔신호이고, 제2 요청신호는 충전기(140)가 차데모표준인 경우에 충전기(140)의 제2 캔신호를 요청하는 캔신호일 수 있다. 이와 같이 배터리 관리 시스템(210)으로부터 제1 및 제2 요청신호가 충전기(140)로 송신되기 때문에 충전기(140)의 종류에 상관없이 충전기(140)로부터 캔신호가 송신되도록 요청할 수 있다.The first request signal is a can signal requesting the first can signal of the charger 140 when the charger 140 is the SGS standard and the second request signal is the can signal when the charger 140 Quot; can " signal. As described above, since the first and second request signals are transmitted from the battery management system 210 to the charger 140, the charger 140 can request that the can signal be transmitted regardless of the type of the charger 140.

한편, 제어부(200)는 충전기(140)로부터 제1 캔신호가 수신되면 상기 요청신호 중 제2 요청신호의 송신을 차단하고, 제2 캔신호가 수신되면 상기 오청신호 중 제1 요청신호의 송신을 차단하는 것을 특징으로 할 수 있다.On the other hand, when the first can signal is received from the charger 140, the control unit 200 blocks the transmission of the second request signal in the request signal, and when the second can signal is received, transmits the first request signal And the like.

즉, 제어부(200)는 충전기(140)로부터 제1 캔신호가 수신되면, 충전기(140)가 SGS표준이기 때문에 차데모표준의 충전기(140)에 캔신호를 요청하는 신호인 제2 요청신호의 송신은 불필요해진다. 따라서, 제2 요청신호의 송신을 차단하도록 제어할 수 있다. 반면, 제어부(200)는 충전기(140)로부터 제2 캔신호가 수신되면, 충전기(140)가 차데모표준이기 때문에 SGS표준의 충전기(140)에 캔신호를 요청하는 신호인 제1 요청신호의 송신은 불필요해진다. 따라서, 제1 요청신호의 송신을 차단함으로써 불필요한 신호 송신을 막을 수 있다.
That is, when the first can signal is received from the charger 140, the controller 200 determines that the second request signal, which is a signal requesting the can signal to the charger 140 of the car demo standard, The transmission becomes unnecessary. Therefore, it is possible to control the transmission of the second request signal to be blocked. On the other hand, when the second can signal is received from the charger 140, the controller 200 determines that the first request signal, which is a request signal to the charger 140 of the SGS standard, The transmission becomes unnecessary. Therefore, unnecessary signal transmission can be prevented by blocking transmission of the first request signal.
