Description

충전기를 이용한 전기자동차 원격 고장 진단 방법How to remotely diagnose electric vehicle failure using a charger
본 발명은 전기자동차의 고장 진단 방법에 관한다.The present invention relates to a method for diagnosing a fault in an electric vehicle.
많은 국가에서 전기자동차가 제조되어 판매하고 있다. 오늘날 전기자동차는 뛰어난 성능과 승차감으로 인해 많은 사람에게 사랑받고 있으며, 앞으로도 전기자동차 시장은 확대일로에 있을 것으로 예상한다. 물론 순탄한 길만 있는 것은 아니다. 여전히 많은 문제가 전기자동차 산업의 앞을 가로막고 있다. 값비싼 개발 비용과 부족한 충전 인프라와 안전성 문제가 이 산업의 큰 장애물이다. 특히 최근 발생하는 전기자동차 화재 사건은 전기차를 사려고 했던 사람들에게 부정적인 인식을 남겼다. 전기자동차의 동력원인 고전압 배터리의 경우, 불안정한 상태에서 발화가 발생하기 쉽고, 발화되면 연쇄 폭발 반응이 발생하여 화재 진압이 쉽지 않다는 문제가 있다. 그렇기 때문에 화재를 예방하는 것이 전기자동차에서 무엇보다 중요하다. Electric vehicles are being manufactured and sold in many countries. Today, electric vehicles are loved by many people due to their excellent performance and riding comfort, and the electric vehicle market is expected to continue to expand in the future. Of course, it is not all smooth roads. Many problems are still blocking the electric vehicle industry. Expensive development costs, insufficient charging infrastructure, and safety issues are major obstacles to this industry. In particular, recent electric car fire incidents have left a negative impression on people who wanted to buy electric cars. In the case of high-voltage batteries, which are the power source of electric vehicles, ignition is easy to occur in an unstable state, and when ignition occurs, a chain explosive reaction occurs, making it difficult to extinguish the fire. Therefore, preventing fire is of utmost importance in electric vehicles.
그런데 전기자동차의 경우 예방 진단이 내연기관 자동차보다 훨씬 까다롭다. 엔진과 미션이 존재하지 않는다는 점이 전기자동차의 큰 장점이기는 해도, 바로 이것이 예방 진단에 어려움을 초래한다. 경고등이 표시되기 전까지 전기자동차 운전자가 정비소를 방문하는 경우가 흔하지 않기 때문이다. 간단한 소모품의 경우 직접 구매하여 교체할 수도 있기 때문에, 운전자가 좀처럼 정비소에 가지 않게 되는 것이다. 역설적이게도 전기자동차의 장점이 오히려 고장에 대한 조기 진단을 어렵게 만든다. However, in the case of electric vehicles, preventive diagnosis is much more difficult than for internal combustion engine vehicles. Although the absence of an engine and transmission is a major advantage of electric vehicles, this creates difficulties in preventive diagnosis. This is because it is not common for electric vehicle drivers to visit a repair shop before the warning light is displayed. Simple consumables can be purchased and replaced directly, so drivers rarely have to go to a repair shop. Paradoxically, the advantages of electric vehicles actually make early diagnosis of malfunctions difficult.
본 발명의 발명자는 이러한 상황을 타개하기 위하여 연구하고 노력한 결과 매우 획기적인 기술 솔루션을 탐색하여 본 발명을 완성하기에 이르렀다. As a result of research and effort to overcome this situation, the inventor of the present invention discovered a very groundbreaking technical solution and completed the present invention.
전기자동차 운전자(소유자)는 내연기관 차량과 달리 언제 정비소에서 정비를 받아야 할지 모른다. 전기자동차 고장에 대한 조기 진단이 어려운 상황이다. 그런데 전기자동차는 배터리를 충전하기 위해서 반드시 충전기가 설치된 인프라에 연결되어야 한다. 본 발명은 이 연결에 주목한다. 즉, 본 발명의 목적은 전기자동차의 배터리를 충전할 때, 차량에서 인프라로 고장 진단 데이터가 전달되도록 하고, 그 데이터를 정비소가 획득하도록 시스템을 구성함으로써, 전기자동차 운전자가 원격으로 진단받을 수 있도록 하는 신규한 방법을 제안하는 것이다. Unlike vehicles with internal combustion engines, drivers (owners) of electric vehicles do not know when they will need to receive maintenance at a repair shop. Early diagnosis of electric vehicle failures is difficult. However, in order to charge the battery, electric vehicles must be connected to infrastructure with a charger installed. The present invention focuses on this connection. In other words, the purpose of the present invention is to enable failure diagnosis data to be transmitted from the vehicle to the infrastructure when charging the battery of an electric vehicle, and to configure a system so that the repair shop can obtain the data, so that the driver of the electric vehicle can be diagnosed remotely. It proposes a new way to do this.

The electric vehicle 10 is connected to an infrastructure charger (Electric Vehicle Supply Equipment: EVSE) 20 through a charging cable. Then, the electric vehicle 10 and the charger 20 perform battery charging while exchanging data about charging.

도 2는 본 발명의 바람직한 어느 실시예에 따른 시스템 구성을 개략적으로 나타낸다.Figure 2 schematically shows the system configuration according to a preferred embodiment of the present invention.
전기자동차(10)는 충전 케이블을 이용하여 인프라 충전기(Electric Vehicle Supply Equipment: EVSE)(20)에 연결된다. EVSE(20)는 전기자동차(10)에 전력을 제공하여 전기자동차(10) 배터리를 충전한다. 전기자동차는 전력망에서 전기를 배터리에 충전하여 구동하기 때문에 충전 인프라와 긴밀한 관계가 있고, 충전 인터페이스, 전력량 계측 및 과금, 전력계통과의 연계, 충전 안전성 확보, 다양한 차종의 배터리 규격에 대한 대응 등의 복잡한 문제를 통일하기 위해 전기자동차 충전 기술에 관한 국제표준이 마련되어 있다. 전기자동차에 대한 국제표준은 ISO(International Organization for Standardization: 국제표준화기구)와 IEC(International Electrotechnical Commission: 국제전기표준회의)에서 표준화를 진행한다. 충전 커넥터 등의 전기부품 분야의 표준화는 IEC가, 차량과 그리드 사이에서 이루어지는 통신 규격에 대한 표준화는 ISO가 담당하고 있다. 예컨대 전기차용 커넥터-인렛 공통 표준은 IEC 62196-1 표준이, 교류 전기차용 커넥터-인렛 표준은 IEC 62196-2 표준이, 직류 전기차용 커넥터-인렛 표준은 IEC 62196-3으로 정해져 있다. 또한 전기차 충전 일반사항은 ISO 15118-1 표준으로, OSI 계층별 요구사항은 ISO 15118-2 표준으로, 물리/데이터링크 계층 요구사항은 ISO 15118-3 표준으로 정해져 있다. 위와 같은 표준에 의해서 전기자동차(10) 배터리 충전 관련 데이터는 충전 케이블을 통해 EVSE(20)로 전달된다. The electric vehicle 10 is connected to an infrastructure charger (Electric Vehicle Supply Equipment: EVSE) 20 using a charging cable. EVSE 20 provides power to the electric vehicle 10 to charge the battery of the electric vehicle 10. Since electric vehicles are driven by charging electricity to batteries from the power grid, they are closely related to the charging infrastructure, and complex tasks such as charging interface, power measurement and billing, connection with the power system, ensuring charging safety, and responding to battery specifications of various vehicle types are required. In order to unify the problem, international standards for electric vehicle charging technology have been established. International standards for electric vehicles are standardized by ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission). IEC is responsible for standardization of electrical components such as charging connectors, and ISO is responsible for standardization of communication standards between vehicles and the grid. For example, the common standard for connector-inlets for electric vehicles is the IEC 62196-1 standard, the connector-inlet standard for AC electric vehicles is the IEC 62196-2 standard, and the connector-inlet standard for DC electric vehicles is IEC 62196-3. In addition, general electric vehicle charging requirements are set by the ISO 15118-1 standard, OSI layer-specific requirements are set by the ISO 15118-2 standard, and physical/data link layer requirements are set by the ISO 15118-3 standard. According to the above standards, data related to battery charging of the electric vehicle 10 is transmitted to the EVSE 20 through the charging cable.
충전 관련 데이터는 배터리 상태(사용가능여부), 배터리 SOC(%), 배터리 전압(V), 배터리 전류(A), 배터리 잔량(Wh), 절연저항 등이 있다.Charging-related data includes battery status (availability), battery SOC (%), battery voltage (V), battery current (A), battery remaining capacity (Wh), and insulation resistance.
EVSE(20)는 통신망을 통해 충전 정보 매니지먼트 서버(50)와 통신하며, 충전 관련 데이터를 충전 정보 매니지먼트 서버(50)로 전송한다. 바람직하게는 EVSE 관제센터를 경유할 수 있다. 이것을 <제2시스템>이라고 칭했다. 제2 시스템에는 N(N은 1보다 큰 정수이다)개의 EVSE(20)가 존재할 것이다.The EVSE 20 communicates with the charging information management server 50 through a communication network and transmits charging-related data to the charging information management server 50. Preferably, it can be done via the EVSE control center. This was called <Second System>. In the second system, there will be N (N is an integer greater than 1) EVSE 20.
충전 정보 매니지먼트 서버(50)는 EVSE(20) 및 전기자동차(10)로부터 전달된 충전 관련 데이터를 데이터베이스(51)에 보관한다. 또한 인프라 충전기 정보 및 로그 데이터와, 충전 관련 데이터를 처리하여 다중이 이용할 수 있는 전기차 운영 데이터 센터로서 제2시스템인 충전 정보 시스템(55)을 구축한다. 전기차 운전자들의 스마트폰(1)은 인터넷 혹은 스마트폰 애플리케이션을 실행하여 제2시스템인 충전 정보 시스템(55)을 접속할 수 있다. 제2시스템을 통해 전기차 운전자들은 전기차 충전소의 위치, 충전소의 충전방식 현황, 충전기의 이용 상황, 실시간 충전정보(충전량, 충전시간, 충전속도) 등을 열람할 수 있다. EVSE(20)로 전기자동차(10) 배터리를 충전한 결과 제공되는 이러한 서비스는 공지의 기술이다. 즉, 도 2에서 제2시스템의 충전 정보 시스템(55)는 공지의 영역에 속한다. 그러나 제1시스템의 전기차 관리 시스템(150)은 미지의 영역이다.The charging information management server 50 stores charging-related data transmitted from the EVSE 20 and the electric vehicle 10 in the database 51. In addition, a second system, the charging information system 55, is built as an electric vehicle operation data center that can be used by multiple people by processing infrastructure charger information, log data, and charging-related data. Smartphones 1 of electric vehicle drivers can access the second system, the charging information system 55, by running an Internet or smartphone application. Through the second system, electric vehicle drivers can view the location of the electric vehicle charging station, the status of the charging method at the charging station, the usage status of the charger, and real-time charging information (charge amount, charging time, charging speed). This service provided as a result of charging the battery of the electric vehicle 10 with the EVSE 20 is a known technology. That is, in FIG. 2, the charging information system 55 of the second system belongs to the known area. However, the electric vehicle management system 150 of the first system is unknown territory.
본 발명에서는 전기자동차(10)와 EVSE(20) 사이의 통신 프로토콜에서 신규한 프로토콜을 추가한다. 이로써 EVSE(20)는 전기자동차(10)로부터 고장 진단 관련 데이터를 입수할 수 있다. 그런 다음 EVSE(20)는 통신망을 통해 차량 정비 매니지먼트 시스템 서버(100)로 고장 진단 관련 데이터를 전송한다. 바람직하게는 EVSE 관제센터를 경유할 수 있다. 이것을 <제1 시스템>이라고 칭했다.In the present invention, a new protocol is added to the communication protocol between the electric vehicle 10 and the EVSE 20. As a result, the EVSE 20 can obtain data related to fault diagnosis from the electric vehicle 10. Then, the EVSE 20 transmits fault diagnosis-related data to the vehicle maintenance management system server 100 through a communication network. Preferably, it can be done via the EVSE control center. This was called <First System>.
고장 진단 관련 데이터는 파워트레인 부품 수명에 관한 데이터, 즉 주행용 배터리, 온 보드 차저, 인버터, E 모터 등의 상태에 관한 데이터를 포함한다. 이런 데이터는 차량 정비 매니지먼트 시스템 서버가 부품 교체 정보로 변환될 수 있다. 또한 고장 진단 관련 데이터는 전기차 안전에 관련된 사항, 예컨대 전기차 배터리 화재 발생 가능성 혹은 주행중 전기차 시동 꺼짐 발생 가능성에 관한 데이터를 포함할 수 있다.Data related to fault diagnosis includes data on the lifespan of powertrain components, that is, the status of the driving battery, on-board charger, inverter, E-motor, etc. This data can be converted into parts replacement information by the vehicle maintenance management system server. Additionally, data related to fault diagnosis may include data related to electric vehicle safety, such as the possibility of an electric vehicle battery fire or the possibility of the electric vehicle starting off while driving.
이러한 고장 진단 관련 데이터는 충전 프로세스를 통해 전기자동차(10)에서 EVSE(20)로 전달된다. This fault diagnosis-related data is transferred from the electric vehicle 10 to the EVSE 20 through the charging process.
차량 정비 매니지먼트 시스템 서버(100)는 하나 이상의 서버장비로 이루어지며 EVSE(20) 시스템으로부터 수신한 고장 진단 관련 데이터를 데이터베이스(105)에 보관한다. 또한 차량 정비 매니지먼트 시스템 서버(100)는 제1 시스템인 전기차 관리 시스템(150)을 구축한다. 전기차 관리 시스템(150)은 고장 진단 관련 데이터를 처리하고 보관하며, 미리 등록되어 있는 운전자의 스마트폰(1)으로 미리 정한 규칙에 따라 고장 진단 정보를 전달한다. The vehicle maintenance management system server 100 consists of one or more server devices and stores fault diagnosis-related data received from the EVSE 20 system in the database 105. Additionally, the vehicle maintenance management system server 100 builds the first system, the electric vehicle management system 150. The electric vehicle management system 150 processes and stores data related to failure diagnosis, and delivers failure diagnosis information to the pre-registered driver's smartphone 1 according to predetermined rules.
전기차 운전자의 스마트폰(1)은 스마트폰 애플리케이션을 실행하여 전기차 관리 시스템(150)에 접속할 수 있다. 또한 스마트폰(1)은 인터넷을 통해 전기차 관리 시스템(150)에 접속할 수 있다. 또한 차량 정비 매니지먼트 시스템 서버(100)는 미리 정한 규칙(예컨대 부품 교체 주기 또는 부품 상태 정보)에 따라 운전자 스마트폰(1)으로 고장 진단 정보를 메시지로 전송할 수 있다. 이러한 메시지에는 부품 교체 메시지를 포함한다.The electric vehicle driver's smartphone 1 can access the electric vehicle management system 150 by running a smartphone application. Additionally, the smartphone 1 can access the electric vehicle management system 150 through the Internet. Additionally, the vehicle maintenance management system server 100 may transmit failure diagnosis information as a message to the driver's smartphone 1 according to predetermined rules (for example, part replacement cycle or part status information). These messages include parts replacement messages.
본 발명에서 EVSE(20)는 어떻게 전기자동차의 고장 진단 관련 데이터를 획득하는 것일까? 이에 대해서 설명한다.In the present invention, how does the EVSE 20 obtain data related to fault diagnosis of an electric vehicle? This will be explained.
한편 도 3은 본 발명의 바람직한 다른 실시예에 따른 시스템 구성을 개략적으로 나타낸다.Meanwhile, Figure 3 schematically shows the system configuration according to another preferred embodiment of the present invention.
서버 측의 구성은 도 2와 실시예와 실질적으로 동일하다. 그러나 제1 시스템을 통해 고장 진단 정보를 수신하는 디바이스가 운전자의 스마트폰이 아니라 차량에 설치된 무선 통신 단말이다. 즉, 무선 통신 기능이 있는 차량 통신 단말(11)이 설치되고, 해당 차량 통신 단말(11)의 식별번호를 제1 시스템의 차량 정비 매니지먼트 서버에 미리 등록한다. 그런 다음 차량 정비 매니지먼트 시스템 서버(100)가 고장 진단 정보를 차량 통신 단말(11)로 전송한다.The configuration of the server side is substantially the same as that in Figure 2 and the embodiment. However, the device that receives fault diagnosis information through the first system is not the driver's smartphone, but a wireless communication terminal installed in the vehicle. That is, a vehicle communication terminal 11 with a wireless communication function is installed, and the identification number of the vehicle communication terminal 11 is registered in advance in the vehicle maintenance management server of the first system. Then, the vehicle maintenance management system server 100 transmits the fault diagnosis information to the vehicle communication terminal 11.
고장 진단 정보는 차량 통신 단말(11)에 연결된 디스플레이를 통해 메시지로 표시될 수 있다. 운전자는 디스플레이를 통해 표시된 메시지를 확인함으로써 정비소에 가야 한다는 사실을 인지한다. Failure diagnosis information may be displayed as a message through a display connected to the vehicle communication terminal 11. The driver recognizes the need to go to the repair shop by checking the message displayed on the display.
도 4는 본 발명의 바람직한 어느 실시예에 따른 충전 케이블의 플러그(30)의 구성 예를 개략적으로 나타내었다. DC 고속 충전을 할 수 있는 CCS Type 1의 핀 레이아웃을 예시로 보여준다. Figure 4 schematically shows an example of the configuration of the plug 30 of a charging cable according to a preferred embodiment of the present invention. The pin layout of CCS Type 1, which enables DC fast charging, is shown as an example.
도 2의 충전 케이블의 플러그(30)는 전력을 공급하는 제1라인(31)과 제2라인(32), CP 라인(33), PP 라인(34), 보호 접지(35), DC 전력을 공급하는 DC 라인(38, 39)으로 구성된다. 위의 다섯 개의 핀은 AC 완속 충전을, 아래의 두 개의 핀은 DC 급속 충전을 제공한다. The plug 30 of the charging cable in FIG. 2 connects the first line 31 and second line 32, CP line 33, PP line 34, protective ground 35, and DC power that supply power. It consists of supplying DC lines (38, 39). The top five pins provide AC slow charging, and the bottom two pins provide DC fast charging.
충전 케이블의 CP 라인(33)과 PP 라인(34)은 통신을 담당한다. 충전기가 정상적으로 동작하여 전기차의 배터리를 충전할 수 있으려면 전기차와 EVSE간 정보 교환이 필요하다. CP(Control Pilot) 라인(33)은 그런 정보 교환을 담당하는 것으로 전기차와 충전기(EVSE) 사이에 충전 메시지를 송수신한다. CP 신호는 EVSE에서 발생하는 전기 신호로 파일럿 접점과 접지를 통해 차량에 전달된다. 전기자동차와 EVSE의 연결 확인, 전기자동차의 상태에 따라 전력 공급/차단 결정, 충전 시스템의 환기 요구사항을 결정, EVSE에서 공급 가능한 최대 전류값을 차량에 전달 등의 기능을 한다. CP 신호는 PWM 변조 방식의 파일럿 회로로서 모든 충전 시스템에 적용된다. 본 발명의 바람직한 어느 실시예에서는 전기자동차 충전이 종료된 다음에, 이 CP 라인(33)을 통해 전기자동차가 고장 진단 관련 데이터를 EVSE로 전송할 수 있다. The CP line (33) and PP line (34) of the charging cable are responsible for communication. For the charger to operate normally and charge the battery of the electric vehicle, information exchange between the electric vehicle and EVSE is necessary. The CP (Control Pilot) line 33 is responsible for such information exchange and transmits and receives charging messages between the electric vehicle and the charger (EVSE). The CP signal is an electrical signal generated from the EVSE and is transmitted to the vehicle through the pilot contact and ground. It performs functions such as checking the connection between the electric vehicle and EVSE, determining power supply/off according to the status of the electric vehicle, determining ventilation requirements of the charging system, and delivering the maximum current value that can be supplied from the EVSE to the vehicle. The CP signal is a PWM modulation pilot circuit and is applied to all charging systems. In a preferred embodiment of the present invention, after charging of the electric vehicle is completed, the electric vehicle can transmit fault diagnosis-related data to the EVSE through the CP line 33.
PP(Proximity Pilot 라인(34)는 EVSE의 충전기가 전기자동차의 충전구에 꽂혀 있는지를 탐지하며, 그 연결 설정을 지속적으로 확인하는 기능을 한다. 본 발명의 바람직한 다른 실시예에서는 이 PP 라인(34)에 새로운 전력선 통신 프로토콜을 정의하고 그것을 이용하여 전기자동차가 고장 진단 관련 데이터를 EVSE로 전송하는 것이다. PP 라인(34)을 이용한 실시예는 전기자동차 충전과 상관없이 고장 진단에 대한 정보를 전송할 수 있는 장점이 있다.The PP (Proximity Pilot line 34) detects whether the EVSE charger is plugged into the charging port of the electric vehicle and functions to continuously check the connection settings. In another preferred embodiment of the present invention, this PP line (34) ) defines a new power line communication protocol and uses it to transmit fault diagnosis-related data to the EVSE in an embodiment in which information on fault diagnosis is transmitted regardless of the electric vehicle charging. There is an advantage.
도 5는 본 발명의 바람직한 어느 실시예에 따른 전기자동차 원격 고장 진단 방법의 전체 프로세스를 예시하였다. 본 발명의 방법은 EVSE의 충전기를 이용하여 전기자동차의 고장 진단을 수행하는 것이다. 당업자는 본 발명의 기술사상은 전기자동차의 고장 진단을 수행하는 것 자체에 있지 않음을 이해할 것이다. 본 발명은 전기자동차의 운전자(소유자)가 정비소에 직접 가지 않더라도 원격에서 자신의 차량 안에서 또는 스마트폰으로 전기자동차의 고장 진단에 관련한 정보를 얻을 수 있는 서비스에 특징이 있다. 따라서 먼저 전기자동차 차량 통신 단말 또는 운전자의 스마트폰을 차량 정비 매니지먼트 시스템 서버에 미리 등록하는 것이 바람직하다.Figure 5 illustrates the entire process of the electric vehicle remote failure diagnosis method according to a preferred embodiment of the present invention. The method of the present invention is to perform fault diagnosis of an electric vehicle using an EVSE charger. Those skilled in the art will understand that the technical idea of the present invention does not lie in performing fault diagnosis of an electric vehicle itself. The present invention is characterized by a service that allows the driver (owner) of an electric vehicle to obtain information related to fault diagnosis of an electric vehicle remotely from within his or her vehicle or via a smartphone, even if the driver (owner) does not go directly to the repair shop. Therefore, it is desirable to first register the electric vehicle vehicle communication terminal or the driver's smartphone in the vehicle maintenance management system server.
이러한 방법은 차량 안에서 벌어지는 이벤트를 새롭게 정의해야 하며, EVSE 계통을 통해 수집되는 데이터 처리 및 관리에 기초한 차량 바깥의 신규한 서비스를 서버 측에서 정의해야 한다. 전자는 충전 케이블에서 새로운 프로토콜을 정의함으로써, 후자는 제1 시스템을 구축함으로써 실행된다. 또한 전술한 충전 케이블의 프로토콜 정의 과정에서는, 고장 진단 관련 데이터를 새로운 프로토콜을 통해 EVSE에 전달할 수 있는 PLC 모뎀을, 전기자동차와 충전기 양쪽에 새롭게 정의하는 것이 바람직하다(PP 라인을 이용하는 실시예의 경우). 더욱이 제1 시스템과의 무선 통신을 통해 수신한 고장 진단 정보를 디스플레이에 표시하기 위한 솔루션이 차량 제어 유닛에 적용되는 것이 좋다.This method must redefine events that occur inside the vehicle and define new services outside the vehicle on the server side based on the processing and management of data collected through the EVSE system. The former is implemented by defining a new protocol in the charging cable, and the latter is implemented by building the first system. In addition, in the process of defining the protocol of the charging cable described above, it is desirable to newly define a PLC modem that can transmit fault diagnosis-related data to the EVSE through a new protocol for both the electric vehicle and the charger (in the case of an embodiment using a PP line) . Furthermore, it is preferred that a solution for displaying fault diagnosis information received through wireless communication with the first system on a display is applied to the vehicle control unit.
먼저 전기자동차의 충전 커넥터가 EVSE의 충전 케이블을 통해 연결된다(S100). 그러면 전기자동차는 충전 케이블의 CP 라인 혹은 PP 라인을 통해 EVSE로 고장 진단 관련 데이터를 전송한다(S110). First, the charging connector of the electric vehicle is connected through the EVSE charging cable (S100). Then, the electric vehicle transmits fault diagnosis-related data to the EVSE through the CP line or PP line of the charging cable (S110).
EVSE는 고장 진단 관련 데이터를 통신망을 통해 차량 정비 매니지먼트 시스템 서버로 전송한다(S120).EVSE transmits fault diagnosis-related data to the vehicle maintenance management system server through the communication network (S120).
차량 정비 매니지먼트 시스템 서버는 수신한 고장 진단 관련 데이터를 분석하여 차량 운전자가 용이하게 이해할 수 있도록 변환된 고정 진단 정보를 생성한다(S130).The vehicle maintenance management system server analyzes the received fault diagnosis-related data and generates converted fixed diagnosis information so that the vehicle driver can easily understand it (S130).
만약 고장 진단 정보에는 특별히 조치를 취할 필요가 없는 경우도 있을 것이다. 그렇다면 해당 차량에 대한 로그만을 기록할 수 있다. 만약 고장 진단 정보에 정비 조치가 필요한 경우, 미리 등록한 사용자 디바이스, 즉 차량 통신 단말 또는 운전자 스마트폰으로 고장 진단 정보를 푸시할 수 있다(S140). 전기차 관리 시스템의 페이지에 고장 진단 정보를 저장하고, 그 링크를 운전자 스마트폰으로 보낼 수도 있다. There may be cases where no special action is needed for fault diagnosis information. If so, only logs for that vehicle can be recorded. If the fault diagnosis information requires maintenance action, the fault diagnosis information can be pushed to a pre-registered user device, that is, the vehicle communication terminal or the driver's smartphone (S140). Failure diagnosis information can be saved on the electric vehicle management system page and the link can be sent to the driver's smartphone.
바람직하게는 상기 고장 진단 정보로는 정비소 정비 알림 메시지를 포함한다. 내연기관 차량과 달리, 전기자동차의 경우 엔진이 없기 때문에 정비소에 잘 가지 않으며, 언제 정비소의 정비를 받아야 할지 알지 못한다. 그러므로 본 발명에서는 정비소 정비가 필요하다는 알림 메시지를 적시에 제공할 수 있으므로, 전기자동차의 정비 불량에서 비롯되는 사고를 예방하는 데 매우 탁월하다.Preferably, the failure diagnosis information includes a garage maintenance notification message. Unlike vehicles with internal combustion engines, electric vehicles do not have an engine, so they do not go to the repair shop often, and they do not know when to receive maintenance. Therefore, the present invention is excellent for preventing accidents resulting from poor maintenance of electric vehicles because it can provide a timely notification message that maintenance at a garage is necessary.
본 발명의 방법에 따르면, 전기자동차가 충전 케이블의 CP 라인 또는 PP 라인을 통해 고장 진단 관련 데이터를 EVSE로 전송한다. CP 라인의 프로토콜과 PP 라인의 프로토콜은 표준 규약으로 정해져 있다. 그러므로 표준 규약에 고장 진단 관련 데이터를 추가하는 것이 바람직하다. 그 방법은 당업자라면 쉽게 이해할 수 있을 것이다. 도 6에 도시되어 있는 것처럼, ISO/IEC 15118-2에서 OSI (Open System Interconnection) 계층 7 단계(301)의 Application Layer Message(303)에 고장 진단 관련 데이터를 추가하는 것이다. CP 라인을 이용하는 경우에는 충전 수행 외의 시간에 고장 진단 관련 데이터가 전송되도록 한다. PP 라인을 이용하는 경우, PP 라인의 프로토콜이 연결상태를 확인하는 기능에 관하므로, 충전과 상관없이 고장 진단 관련 데이터가 전송되도록 할 수 있다.According to the method of the present invention, the electric vehicle transmits fault diagnosis-related data to the EVSE through the CP line or PP line of the charging cable. The protocol of the CP line and the protocol of the PP line are established as standard protocols. Therefore, it is desirable to add data related to fault diagnosis to the standard protocol. The method can be easily understood by those skilled in the art. As shown in FIG. 6, in ISO/IEC 15118-2, fault diagnosis-related data is added to the Application Layer Message (303) of the OSI (Open System Interconnection) layer 7 level (301). When using the CP line, ensure that data related to fault diagnosis is transmitted at times other than charging. When using the PP line, the protocol of the PP line involves the function of checking the connection status, so data related to fault diagnosis can be transmitted regardless of charging.
