Abstract

The present invention relates to a diagnostic device that is required for reusing electric vehicle batteries. Electric vehicle batteries need to be reused, both from an environmental perspective and an industrial policy perspective. However, there are technical and practical difficulties in reusing electric vehicle batteries. Before a battery can be reused, the battery must be diagnosed. However, due to the risk of hacking of a battery BMS, manufacturers do not disclose detailed technology, specifications of a physical interface of a battery pack are different for each vehicle model, and communication protocols are also different for each vehicle model. As a result, diagnostic devices have to be manufactured for each battery and vehicle model. The present invention proposes a solution that can most efficiently diagnose a battery with a single diagnostic device. A key code circuit unit that specifies a vehicle model is installed on a cable for an electric vehicle battery diagnostic device, and the diagnostic device can automatically select the vehicle model through a preset key code value.

Description

전기자동차 배터리 진단 장비용 케이블 및 그 케이블을 이용한 차종 선택 방법Cable for electric vehicle battery diagnostic equipment and method of selecting vehicle model using the cable
본 발명은 전기자동차의 배터리 재사용에 관한 기술이다.The present invention is a technology related to battery reuse of electric vehicles.
지구 환경을 위해서 각 나라의 정부는 전기 자동차의 보급 촉진을 위해 힘쓰고 있다. 정부 주도의 전기자동차 보급 정책은 구매 보조금을 지급하는 방식으로 실행된다. 대한민국의 구매 보조금은 정부가 배터리를 소비자 대신 구매하는 명목으로 지급된다. 따라서 전기차 소유자가 해당 차량의 폐기 등으로 인해 자동차 등록을 말소할 경우, 배터리를 반납해야 한다. 그러면 반납한 전기차의 배터리를 수거하여 분해하고 해체한 다음 배터리에 내장된 희귀 금속(리튬, 니켈, 망간, 코발트 등)이나 비철금속(구리, 알루미늄 등)을 추출하여 재활용할 수 있다. 그러나 이러한 단순 폐기물 처리보다는 배터리 자체를 재사용하는 것이 훨씬 경제적이며 환경적으로 가치 있는 활용방법이다.For the sake of the global environment, governments in each country are working to promote the distribution of electric vehicles. The government-led electric vehicle distribution policy is implemented by providing purchase subsidies. In Korea, purchase subsidies are provided by the government in the name of purchasing batteries on behalf of consumers. Therefore, if the electric vehicle owner cancels the vehicle registration due to disposal of the vehicle, the battery must be returned. Then, the battery of the returned electric vehicle can be collected, disassembled and dismantled, and the rare metals (lithium, nickel, manganese, cobalt, etc.) or non-ferrous metals (copper, aluminum, etc.) contained in the battery can be extracted and recycled. However, reusing the battery itself is a much more economical and environmentally valuable method of use than simple waste disposal.
예를 교통사고가 발생하여 차량을 폐기해야 하지만 배터리는 온전한 경우가 있다. 이런 경우 배터리를 전기차에 재사용할 수 있다. 같은 모델의 전기차에 배터리를 재사용하는 방법이 아니더라도 농업용 기계나 건설기계 등에 배터리의 2차 사용을 시도할 수도 있다. 또는 배터리 팩을 분해하여 그 안에 내장된 배터리를 선별적으로 재사용하는 것도 가능하다. 어떤 방식으로든 전기차 배터리를 단순 폐기물 처리로 재활용하기보다는 배터리를 재사용하는 방식으로 접근하는 것이 바람직하다.For example, there may be a car accident and the vehicle must be scrapped, but the battery is still intact. In this case, the battery can be reused in an electric vehicle. Even if reusing the battery for an electric vehicle of the same model is not possible, secondary use of the battery for agricultural machinery or construction machinery can be attempted. Alternatively, it is possible to disassemble the battery pack and selectively reuse the batteries contained within it. In any case, it is desirable to approach battery reuse rather than recycling electric vehicle batteries through simple waste disposal.
그러나 배터리의 재사용은 상당히 어려운 것이 당면한 현실이다. 배터리를 재사용하려면 먼저 배터리를 진단할 수 있어야 하고, 해당 배터리에 대한 정확한 정보를 입수해야 한다. 그러나 전기자동차 메이커가 배터리에 관한 정보를 공개할 수 있을까? 전기자동차 배터리에 대한 정보는 배터리 BMS(Battery Management System)에서 관리한다. 그러나 배터리 제조사와 전기자동차 제조사는 이 BMS 정보를 공유하지 않는다. 왜냐하면 BMS에서 관리하는 정보가 외부에 공개되는 경우, 그 정보를 이용하여 전기자동차 해킹이 가능하기 때문이다. 배터리 정보 해킹은 전기자동차를 시한폭탄처럼 사용할 수 있어서 매우 위험하며 교통사고를 일으키는 요인이 될 수 있다. 이런 이유로 차량 제조사는 BMS 정보를 공개하지 않는 것이다. 이런 상황에서 배터리를 재사용하려면, 제조사 별로 고유한 폐배터리 진단장비를 만들어서, 배터리 팩을 해당 진단장비에 연결하고, 배터리의 수명과 상태에 관한 정보만을 표시되도록 하는 방법을 이용해야 한다.However, the reality is that reusing batteries is quite difficult. To reuse a battery, you must first be able to diagnose the battery and obtain accurate information about the battery. But can electric car manufacturers disclose information about their batteries? Information about electric vehicle batteries is managed by the battery BMS (Battery Management System). However, battery manufacturers and electric vehicle manufacturers do not share this BMS information. This is because if the information managed by the BMS is disclosed to the outside, hacking of electric vehicles is possible using that information. Hacking battery information is very dangerous because it can use electric vehicles like a time bomb and can be a factor in traffic accidents. For this reason, vehicle manufacturers do not disclose BMS information. In order to reuse batteries in this situation, each manufacturer must create its own waste battery diagnostic equipment, connect the battery pack to the diagnostic equipment, and use a method to display only information about the life and condition of the battery.
그런데 전기자동차 배터리 팩을 외부 장비에 연결하는 인터페이스와 통신 프로토콜이 차종별로 모두 다르다. 결국 종래의 방식에서는 배터리를 재사용하고자 해도 차종별로 전기차 배터리 진단 장비가 필요하게 되었다. 고가의 장비를 차종별로 제조한다는 것은 매우 비효율적이다. 본 발명자는 이러한 문제를 해결하기 위하여 오랫동안 연구한 결과 본 발명을 완성하기에 이르렀다.However, the interface and communication protocol that connects the electric vehicle battery pack to external equipment are different for each vehicle type. Ultimately, in the conventional method, even if the battery was to be reused, electric vehicle battery diagnostic equipment was needed for each vehicle type. Manufacturing expensive equipment for each vehicle type is very inefficient. The present inventor has completed the present invention as a result of long-term research to solve this problem.
전술한 바와 같이, 전기자동차에 내장되는 배터리는 차량마다 모두 다르다. 심지어 제조사가 같더라도 차종에 따라 배터리가 다르다. 그럼에도 불구하고 차종마다 배터리 진단 장비를 제조하는 것은 기술적으로는 합당하더라도 산업상 이용 가능성이 매우 적은 방법론이라는 관점에서 본 발명이 출발한다. 그러므로 본 발명의 목적은 하나의 진단장비로 상이한 전기자동차 배터리들을 진단할 수 있는 방법론을 모색하고 그것을 제안함에 있다. As mentioned above, the batteries built into electric vehicles are different for each vehicle. Even if the manufacturer is the same, the battery is different depending on the vehicle model. Nevertheless, the present invention starts from the perspective that manufacturing battery diagnostic equipment for each vehicle type is a methodology with very little industrial applicability, even if it is technically reasonable. Therefore, the purpose of the present invention is to explore and propose a methodology that can diagnose different electric vehicle batteries with one diagnostic equipment.
N(N은 1 이상의 정수)대의 배터리 진단 장비를 제조하는 것보다는 N대의 배터리 진단 장비용 케이블을 제조하는 것이 훨씬 경제적인 방법이다. 각각의 배터리 진단 장비용 케이블이 하나의 고유한 진단 솔루션이 되도록 하는 것이다. 그러나 이들 케이블에는 공통된 원리가 적용된다. 특정 배터리에 대응하는 대응 케이블 자체가 키코드 역할을 하며, 배터리에 맞는 소프트웨어를 동작하도록 한다. 진단 장비는 진단 장비용 케이블 내부의 회로를 감지하여 차량에 맞는 진단 솔루션을 선택함으로써 배터리를 적확하게 진단할 수 있다. 요컨대 배터리 진단 장비 1대로 다양한 종류의 전기자동차 배터리를 진단할 수 있도록 한다는 것, 그것이 본 발명의 기술적 과제이다. It is a much more economical method to manufacture N cables for battery diagnostic equipment rather than manufacturing N (N is an integer greater than 1) battery diagnostic equipment. The goal is to ensure that each battery diagnostic equipment cable is a unique diagnostic solution. However, common principles apply to these cables. The corresponding cable that corresponds to a specific battery itself serves as a keycode and operates the software appropriate for the battery. The diagnostic equipment can accurately diagnose the battery by detecting the circuit inside the diagnostic equipment cable and selecting a diagnostic solution appropriate for the vehicle. In short, the technical task of the present invention is to be able to diagnose various types of electric vehicle batteries with a single battery diagnostic equipment.

이하 도면을 이용하여 바람직한 실시예로서 본 발명의 원리와 구성을 설명한다. 본 발명을 설명함에 있어서 관련된 공지기능에 대하여 이 분야의 기술자에게 자명한 사항으로서 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명을 생략한다. The principles and configuration of the present invention will be explained as a preferred embodiment using the drawings below. In describing the present invention, if it is determined that related known functions may unnecessarily obscure the gist of the present invention as they are obvious to those skilled in the art, the detailed description thereof will be omitted.
도 1은 본 발명의 바람직한 어느 실시예에 따른 전기자동차 배터리의 재사용을 위한 차종 선택 방법의 개념을 나타낸다.Figure 1 shows the concept of a method for selecting a vehicle type for reuse of an electric vehicle battery according to a preferred embodiment of the present invention.
기본적으로 전기자동차의 배터리를 재사용하려면 차량에서 전기자동차 배터리 팩(10)을 분리해야 한다. 또한 분리된 상태의 자동차 배터리 팩(10)을 진단해야 한다. 그러려면 전기자동차 배터리 팩(10)과 전기자동차 배터리 진단 장비(200)를 배터리 진단 장비용 케이블(100)를 통해 연결해서 전기자동차 배터리 진단 장비(200)가 전기자동차 배터리 팩(10)의 BMS로 전압을 공급함과 동시에 CAN 통신으로 데이터를 주고받을 수 있어야 한다. 또한 그러려면 전기자동차 배터리 진단 장비(200)가 해당 배터리 팩(10)이 어떤 차종에서 사용하는 배터리 팩(10)인지를 알아야 한다. 만약 사용자가 혼동해서 연결된 배터리와 다른 배터리를 진단 장비 소프트웨어에서 선택하면, 장비가 정상적으로 동작하지 않게 된다. 최악의 경우, 잘못된 연결로 말미암아 배터리 혹은 진단 장비가 파손될 수도 있다. Basically, to reuse the battery of an electric vehicle, the electric vehicle battery pack (10) must be separated from the vehicle. Additionally, the separated vehicle battery pack 10 must be diagnosed. To do this, connect the electric vehicle battery pack 10 and the electric vehicle battery diagnostic equipment 200 through the battery diagnostic equipment cable 100 so that the electric vehicle battery diagnostic equipment 200 is connected to the BMS of the electric vehicle battery pack 10. In addition to supplying voltage, it must be possible to send and receive data through CAN communication. In addition, in order to do this, the electric vehicle battery diagnosis equipment 200 must know which type of vehicle the battery pack 10 is used in. If the user is confused and selects a different battery from the connected battery in the diagnostic equipment software, the equipment will not operate properly. In the worst case, incorrect connections may result in damage to the battery or diagnostic equipment.
배터리 팩(10)이 어떤 차종인지 안 다음에 전기자동차 배터리 진단 장비를 연결하는 방법과, 배터리 팩(10)의 차종을 모르지만 전기자동차 배터리 진단 장비를 연결하는 방법이 있을 것이다. 그러나 후자는 사실상 의미가 없다. 차종마다 통신 프로토콜과 인터페이스 규격이 다르기 때문이다. 그렇기 때문에 전자의 방법일지라도 케이블이 차종만큼이나 필요할 수도 있다. 차종만큼 배터리 진단 장비용 케이블(100)을 제작했더라도, 그것을 전기자동차 배터리 진단 장비(200)에 연결한 다음, 진단 장비 화면에서 차종을 선택하는 절차를 실행하여야 한다. 본 발명은 바로 이 국면에서 진단 장비용 케이블(100)을 진단 장비(200)에 연결하는 순간, 진단 장비용 케이블(100) 자체에서 차종을 자동으로 즉시 선택되도록 할 수 있는 방법을 완성하였다.There may be a method of connecting electric vehicle battery diagnostic equipment after knowing what type of vehicle the battery pack 10 is, and a method of connecting electric vehicle battery diagnostic equipment without knowing the vehicle type of the battery pack 10. But the latter is virtually meaningless. This is because communication protocols and interface specifications are different for each vehicle model. Therefore, even with the former method, the cable may be as necessary as the vehicle type. Even if the battery diagnostic equipment cable 100 is manufactured for the number of vehicle models, it must be connected to the electric vehicle battery diagnostic equipment 200 and then the procedure for selecting the vehicle model on the diagnostic equipment screen must be performed. In this context, the present invention has completed a method that allows the diagnostic equipment cable 100 itself to automatically and immediately select the vehicle model the moment the diagnostic equipment cable 100 is connected to the diagnostic equipment 200.
도 2는 본 발명의 바람직한 어느 실시예에 따른 배터리 진단 장비용 케이블(100)의 외관 구성 예를 나타낸다. Figure 2 shows an example of the external configuration of a cable 100 for battery diagnostic equipment according to a preferred embodiment of the present invention.
배터리 진단 장비용 케이블(100)의 한쪽 단부에는 제1 커넥터(110)가 구성되고, 다른 쪽 단부에는 제2 커넥터(190)가 구성된다. 제1 커넥터(110)은 전기자동차 배터리 진단 장비의 커넥터에 연결되고, 제2 커넥터(190)는 전기자동차 배터리 팩의 커넥터에 연결된다. 제2 커넥터(190)는 차종마다 전기자동차 배터리 팩의 커넥터의 물리 규격이 상이하기 때문에 그 규격에 대응하기 위해서 제2 커넥터(190)의 규격도 상이하게 제작한다. 그러나 상이한 제2 커넥터(190)의 규격에도 불구하고, 제1 커넥터(110)의 규격은 1대의 진단 장비와 연결되기 때문에, 제1 커넥터(110)의 물리 규격은 동일하다. A first connector 110 is formed at one end of the battery diagnostic equipment cable 100, and a second connector 190 is formed at the other end. The first connector 110 is connected to the connector of the electric vehicle battery diagnostic equipment, and the second connector 190 is connected to the connector of the electric vehicle battery pack. Since the physical specifications of the connector of the electric vehicle battery pack are different for each vehicle type, the second connector 190 is manufactured to different specifications to correspond to the specifications. However, despite the different specifications of the second connector 190, since the specifications of the first connector 110 are connected to one diagnostic equipment, the physical specifications of the first connector 110 are the same.
진단 장비에 연결되는 제1 커넥터(110)에는 키코드 회로부(130)가 설치된 회로기판이 구성되어 있으며, 이 키코드 회로부(130)는 제1 커넥터(110)의 연결 단자(120)의 일부 연결핀들에 전기적으로 연결되어 특정 키코드 값을 생성한다. The first connector 110 connected to the diagnostic equipment includes a circuit board on which a key code circuit 130 is installed, and this key code circuit 130 connects a portion of the connection terminal 120 of the first connector 110. It is electrically connected to pins to generate a specific keycode value.
본 발명의 방법 및 배터리 진단 시스템에서는 M(M은 1 이상의 정수로, 차종 개수로 정해진다)개의 배터리 진단 장비용 케이블(100)이 구비된다. 전술한 것처럼, 이들 M개의 배터리 진단 장비용 케이블(100)의 제2 커넥터(190)는 저마다 규격이 상이할 수 있다. 그러나 제1 커넥터(110)만큼은 규격이 동일하다. 그럼에도 불구하고 상기 키코드 회로부(130)가 생성하는 제1 커넥터(110)의 키코드 값은 모두 상이하다. 이들 상이한 키코드 값으로 진단 장비는 전기자동차 차종을 자동으로 선택할 수 있다. 차종이 선택됨으로써 배터리 팩의 진단할 수 있는 BMS 프로토콜을 특정할 수 있다.In the method and battery diagnosis system of the present invention, M (M is an integer greater than 1 and is determined by the number of vehicle models) cables 100 for battery diagnosis equipment are provided. As described above, the second connectors 190 of these M cables 100 for battery diagnostic equipment may each have different specifications. However, the specifications for the first connector 110 are the same. Nevertheless, the keycode values of the first connector 110 generated by the keycode circuit unit 130 are all different. With these different keycode values, the diagnostic equipment can automatically select the electric vehicle model. By selecting the vehicle model, the BMS protocol that can diagnose the battery pack can be specified.
전기자동차 배터리와 진단 장비 사이를 본 발명의 케이블로 연결하면, 제1 커넥터(110)의 전자 회로에 인식된 논리 신호의 차이에 의해 그 배터리를 사용하는 차종 선택을 할 수 있다는 것이 본 발명의 인식이다. 진단 장비가 차종 선택을 해야 하는 까닭은 그래야만 정확한 BMS 프로토콜을 특정할 수 있음을 다시 한 번 강조한다. 진단 장비는 사전에 다양한 BMS 프로토콜에 대한 정보를 갖고 있다.The present invention recognizes that by connecting an electric vehicle battery and a diagnostic equipment with the cable of the present invention, the vehicle type using the battery can be selected based on the difference in the logic signal recognized by the electronic circuit of the first connector 110. am. We emphasize once again that the reason why diagnostic equipment must select the vehicle model is that only then can the correct BMS protocol be specified. The diagnostic equipment has information about various BMS protocols in advance.
도 3은 본 발명의 바람직한 어느 실시예에 따른 제1 커넥터(110)의 연결핀부(120)의 구성과 도 2에서의 키코드 회로부(130)의 회로 구성 예를 나타낸다.FIG. 3 shows an example of the configuration of the connecting pin portion 120 of the first connector 110 and the circuit configuration of the key code circuit portion 130 in FIG. 2 according to a preferred embodiment of the present invention.
도시된 실시예에서는 연결 단자(120)를 구성하는 제1 커넥터의 연결핀(121, 121~)이 25개가 있다. 이는 곧 진단 장비 커넥터의 연결핀들도 25개가 있다는 의미가 된다. 25개의 연결핀(121, 121~)의 기능은 회로 설계 시에 미리 설정된다. 25개는 설계 변경 사항이다. 12개의 연결핀으로 커넥터를 구성할 수도 있다. 연결핀이 많아지면 더 많은 키코드를 정의할 수 있기 때문에, 진단 장비 및 케이블이 대응할 수 있는 배터리가 많아지는 장점이 있다. In the illustrated embodiment, there are 25 connection pins 121 and 121~ of the first connector constituting the connection terminal 120. This means that there are 25 connection pins in the diagnostic equipment connector. The functions of the 25 connection pins (121, 121~) are preset during circuit design. 25 are design changes. The connector can also be configured with 12 connecting pins. As the number of connection pins increases, more key codes can be defined, which has the advantage of increasing the number of batteries that diagnostic equipment and cables can support.
도 3의 실시예에서 연결핀(121, 121~) 중 1번 연결핀, 2번 연결핀, 3번 연결핀을 전기적으로 연결하여 키코드 회로를 구성하였다. 1번 연결핀을 입력단으로 하고, 3번 연결핀을 그라운드로 연결하고, 2번 연결핀을 출력단으로 한다. 연결핀 사이에 설치되는 저항 R1과 저항 R2의 크기는 정해져 있다. 예컨대 저항 R1은 1KΩ으로, 저항 R2는 4KΩ으로 하고 1번 연결핀과 연결된 입력단의 공급전압이 5V일 때, P점의 출력 전압이 1V가 되도록 회로 구성을 한다. 즉, 도 3의 제1커넥터를 갖는 진단 장비용 케이블은 P점의 출력 전압이 1V이다. 그리고 이 진단 장비용 케이블의 다른 쪽 제2 커넥터로 연결되는 배터리의 차종은 "XYZ"(이것은 제2 커넥터를 설계할 때 결정되어 있다)이다. In the embodiment of Figure 3, the key code circuit was formed by electrically connecting the first, second, and third connection pins among the connection pins 121 and 121~. Connect pin 1 as the input terminal, connect pin 3 as the ground, and connect pin 2 as the output terminal. The sizes of resistor R1 and resistor R2 installed between connection pins are fixed. For example, resistor R1 is set to 1KΩ, resistor R2 is set to 4KΩ, and when the supply voltage of the input terminal connected to connection pin 1 is 5V, the circuit is configured so that the output voltage at point P is 1V. That is, the cable for diagnostic equipment having the first connector of FIG. 3 has an output voltage of 1V at point P. And the model of the battery connected to the second connector on the other side of the diagnostic equipment cable is "XYZ" (this is determined when designing the second connector).
위와 같은 실시예에서 진단 장비에는 전기자동차 모델 "XYZ"에 대한 배터리 정보, 해당 배터리 BMS와의 통신 프로토콜, 기타 정보가 미리 저장되어 있다. 그런 정보로는 배터리 팩 제조사 정보, 배터리 셀 제조사 정보, 셀 구성, 정격전압, 정격전류, 충전 SOC 범위, 최대전압, 최대전류, 최대충전 C-rate, 최대방전 C-rate, 셀 충전종지전압, 셀 방전종지전압, 충전 종지전류, 방전 종지전류, 용량, 셀간 전압 편차, 배터리 최대 임계온도, 배터리 최소 임계온도, 배터리 사용온도, 절연저항 등이 있다. In the above embodiment, battery information for the electric vehicle model "XYZ", a communication protocol with the corresponding battery BMS, and other information are stored in advance in the diagnostic equipment. Such information includes battery pack manufacturer information, battery cell manufacturer information, cell configuration, rated voltage, rated current, charging SOC range, maximum voltage, maximum current, maximum charge C-rate, maximum discharge C-rate, cell charge end voltage, These include cell discharge end voltage, charge end current, discharge end current, capacity, inter-cell voltage deviation, battery maximum critical temperature, battery minimum critical temperature, battery operating temperature, and insulation resistance.
도 3의 제1 커넥터를 진단 장비에 연결하면, 진단 장비의 5V 공급전압이 진단 장비용 케이블 제1 커넥터의 1번 연결핀으로 공급되고, 이에 따라 진단 장비용 케이블은 2번 연결핀을 통해 1 V의 출력전압을 논리 신호로 진단 장비로 보낸다. 그러면 진단 장비는 해당 케이블이 "XYZ" 전용 케이블임을 인식하여 배터리 진단 소프트웨어는 차종 정보로 "XYZ"를 자동으로 선택한다. 그리고 제2 커넥터로 연결된 배터리 팩으로, "XYZ" 전기자동차의 배터리 팩 BMS 통신 프로토콜에 따른 CAN 통신을 개시한다. 또한 연결된 배터리 팩의 BMS 정보가 입수되면 진단 장비의 배터리 진단 소프트웨어 화면을 통해 해당 배터리의 진단 정보를 표시한다. When the first connector in FIG. 3 is connected to the diagnostic equipment, the 5V supply voltage of the diagnostic equipment is supplied to the No. 1 connection pin of the first connector of the diagnostic equipment cable, and accordingly, the diagnostic equipment cable connects 1 through the No. 2 connection pin. The output voltage of V is sent to the diagnostic equipment as a logic signal. Then, the diagnostic equipment recognizes that the cable is a dedicated cable for "XYZ", and the battery diagnostic software automatically selects "XYZ" as the vehicle model information. And with the battery pack connected to the second connector, CAN communication according to the battery pack BMS communication protocol of the "XYZ" electric vehicle is initiated. In addition, when the BMS information of the connected battery pack is obtained, the diagnostic information of the battery is displayed through the battery diagnostic software screen of the diagnostic equipment.
한편, 나머지 연결 단자(120)의 4번~25번 연결핀들에 대해서는 BMS 전원 공급 기능, 배터리 온도 측정 기능, 배터리의 충전 상태(SOC) 데이터를 전달받는 기능, 배터리 셀 간의 전압 측정 등의 회로 기능이 미리 설정되어 있다.Meanwhile, for connection pins 4 to 25 of the remaining connection terminals 120, circuit functions such as BMS power supply function, battery temperature measurement function, function of receiving battery state of charge (SOC) data, and voltage measurement between battery cells are performed. This is preset.
도 3의 실시예에서는 3개의 연결핀(121)과 2개의 저항을 이용하여 회로 구성을 했던 것인데, 더 많은 연결핀(121)을 이용해서 더 많은 저항으로 회로 구성을 한다면 더 많은 전기자동차 차종에 대응할 수 있을 것이다. In the embodiment of Figure 3, the circuit was constructed using three connection pins 121 and two resistors. If the circuit is constructed with more resistance using more connection pins 121, it can be used in more electric vehicle models. You will be able to respond.
그러므로 도 4는 본 발명의 바람직한 다른 실시예에 따른 제1 커넥터(110)의 연결 단자(120)의 구성과 도 2에서의 키코드 회로부(130)의 회로 구성 예를 나타낸다.Therefore, FIG. 4 shows an example of the configuration of the connection terminal 120 of the first connector 110 and the circuit configuration of the keycode circuit unit 130 in FIG. 2 according to another preferred embodiment of the present invention.
도 3의 실시예와 마찬가지로 연결 단자(120)를 구성하는 제1 커넥터의 연결핀(121, 121~)이 25개가 있다. 도 4의 실시예에서 연결핀(121, 121~) 중 14번 연결핀, 15번 연결핀, 16번 연결핀을 전기적으로 연결하여 제1 키코드 회로를 구성하였다. 또한, 17번 연결핀, 18번 연결핀, 19번 연결핀을 전기적으로 연결하여 제2 키코드 회로를 구성하였다. 제1 키코드 회로에서는, 14번 연결핀을 입력단으로 하고, 16번 연결핀을 그라운드로 연결하고, 15번 연결핀을 M점의 출력단으로 한다. 저항 R1과 저항 R2가 도시되어 있는 것처럼 연결핀들 사이에 저항 회로를 구성한다. 제2 키코드 회로에서는, 17번 연결핀을 입력단으로 하고, 19번 연결핀을 그라운드로 연결하고, 18번 연결핀을 N점의 출력단으로 한다. 저항 R3와 저항 R5로 저항 회로를 구성한다. 14번 연결핀과 17번 연결핀을 통해 진단 장비로부터 5V 전압이 공급된다. 각 저항들의 크기와 M점 및 N점의 출력 전압의 크기가 미리 설정되어 있다. Like the embodiment of FIG. 3, there are 25 connection pins 121, 121~ of the first connector constituting the connection terminal 120. In the embodiment of Figure 4, the first key code circuit was formed by electrically connecting connection pins 14, 15, and 16 among the connection pins 121 and 121~. Additionally, a second key code circuit was formed by electrically connecting connection pins 17, 18, and 19. In the first key code circuit, connection pin No. 14 is used as the input terminal, connection pin No. 16 is connected to the ground, and connection pin No. 15 is used as the output terminal of point M. Resistor R1 and resistor R2 form a resistance circuit between the connection pins as shown.

도 6은 본 발명의 바람직한 어느 실시예에 따른 배터리 진단 장비용 케이블을 이용한 차종 선택 방법의 전체 프로세스를 개략적으로 나타내었다. Figure 6 schematically shows the entire process of a vehicle model selection method using a battery diagnostic equipment cable according to a preferred embodiment of the present invention.
먼저 진단 장비의 배터리 진단 소프트웨어를 세팅한다(S100). 진단 장비가 전기자동차의 배터리를 진단하기 위해서는 전기자동차의 차종에 대한 정보를 입수해야 한다. 그리고 차종별 배터리 진단 장비용 케이블의 미리 설정한 키코드 값, 해당 케이블의 연결핀들에 정의된 기능, 배터리 BMS와 통신하기 위한 CAN 통신의 프로토콜 등이 차종별로, 즉 케이블별로 미리 설정하여 보관한다.First, set the battery diagnosis software of the diagnostic equipment (S100). In order for diagnostic equipment to diagnose the battery of an electric vehicle, it must obtain information about the model of the electric vehicle. In addition, the preset key code value of the battery diagnostic equipment cable for each vehicle type, the functions defined for the connection pins of the cable, the CAN communication protocol for communicating with the battery BMS, etc. are preset and stored for each vehicle type, that is, for each cable.
다음으로 배터리 진단 장비용 케이블을 연결한다(S110). 전술한 바와 같이, 이 케이블의 제1 커넥터를 진단 장비에 연결한다. 그러면 진단 장비는 제1 커넥터를 통해 입력 전압을 케이블로 인가한다(S120). 바람직하게는 대략 5V의 전압을 공급한다. Next, connect the cable for battery diagnostic equipment (S110). As described above, the first connector of this cable connects to the diagnostic equipment. Then, the diagnostic equipment applies the input voltage to the cable through the first connector (S120). Preferably, a voltage of approximately 5V is supplied.
케이블의 제1 커넥터에는 키코드 회로부가 설치되어 있다. 키코드 회로부는 정해진 키코드 값을 진단 장비로 전송한다(S130). 바람직하게는 케이블의 제1 커넥터는 저항 회로를 이용한 출력전압 신호를 키코드 값으로 진단 장비로 보낸다. A key code circuit is installed in the first connector of the cable. The keycode circuit unit transmits the determined keycode value to the diagnostic equipment (S130). Preferably, the first connector of the cable sends an output voltage signal using a resistor circuit as a key code value to the diagnostic equipment.
진단 장비의 제어부는 수신한 키코드 값을 미리 저장되어 있는 키코드 값과 비교하여, 차종을 자동으로 선택한다(S140). 배터리 진단 소프트웨어 화면을 통해 특정된 차종을 보여주고, 케이블을 통해 해당 차종에 대한 CAN 통신을 개시한다. 진단 장비용 케이블의 제2 커넥터를 통해 연결되어 있는 배터리 팩으로 BMS 전원을 공급함과 함께 해당 배터리 팩의 CAN 통신 규격에 맞게 통신을 개시하는 것이다.The control unit of the diagnostic equipment compares the received key code value with a pre-stored key code value and automatically selects the vehicle model (S140). The battery diagnosis software screen displays the specified vehicle model and initiates CAN communication for the vehicle model through the cable. It supplies BMS power to the battery pack connected through the second connector of the diagnostic equipment cable and initiates communication in accordance with the CAN communication standard of the battery pack.
그러면 배터리 팩의 BMS는 진단 장비로 배터리 정보를 전송한다. 진단 장비는 연결되어 있는 배터리 진단 정보를 입수하고(S150), 그 정보를 미리 정한 항목으로 소프트웨어 화면을 통해 표시한다. The battery pack's BMS then transmits battery information to the diagnostic equipment. The diagnostic equipment obtains diagnostic information from the connected battery (S150) and displays the information as predetermined items on the software screen.
이때의 배터리 진단 정보는 배터리 상태, 배터리 SCO, 배터리 전압, 배터리 전류, 배터리 잔량, 절연저항을 포함하며, 또한, 배터리 SOH, 배터리 셀 최대 전압, 배터리 셀 최소 전압, 배터리 셀 최대 온도, 배터리 셀 최소 온도, 최대 전압 셀번호, 최소 전압 셀 번호, 배터리 셀 간 전압 편차 등을 더 포함한다. 즉, 충전에 필요한 정보뿐 아니라, 고장 진단에 필요한 정보도 같이 송수신할 수 있다.Battery diagnostic information at this time includes battery status, battery SCO, battery voltage, battery current, battery remaining capacity, and insulation resistance, as well as battery SOH, battery cell maximum voltage, battery cell minimum voltage, battery cell maximum temperature, and battery cell minimum. It further includes temperature, maximum voltage cell number, minimum voltage cell number, and voltage difference between battery cells. In other words, not only the information necessary for charging but also the information necessary for fault diagnosis can be transmitted and received.
