Description
본 발명은 충전신호의 왜곡이 발생하지 않도록 컨트롤부와 커플러가 일체화E된 충전장치에 관한 것이다.The present invention relates to a charging device in which a control unit and a coupler are integrated to prevent distortion of the charging signal.
한국특허등록 제10-1208320호는 공동주택의 단지 내에 설치되는 충전 스테이션, 전반적인 충전상태를 관장하는 단지 서버 및 세대별 홈 서버를 포함하는 홈네트워크, 충전기 관리 운영을 위한 관리사무소 PC를 인터넷망으로 연계하여, 전기자동차의 충전에서부터 요금 계산 및 과금 처리까지의 전반적인 절차를 일괄적으로 처리할 수 있는 새로운 형태의 전기자동차 충전 방식 및 과금 방식을 구현함으로써, 아파트 등과 같은 공동주택의 제한된 공간에서 다수의 전기자동차를 효율적으로 충전할 수 있으며, 전기자동차 충전과 관련한 전기사용량에 따른 요금 계산 및 과금 절차를 효과적으로 처리할 수 있다.Korean Patent Registration No. 10-1208320 covers a charging station installed within an apartment complex, a home network that includes a complex server that manages the overall charging status and a home server for each household, and a management office PC for charger management and operation via the Internet network. In conjunction, by implementing a new type of electric vehicle charging method and billing method that can handle the overall process from electric vehicle charging to fee calculation and billing processing in one go, Electric vehicles can be charged efficiently, and billing and billing procedures based on electricity usage related to electric vehicle charging can be effectively processed.
또한, 충전을 위한 사용자 인증 및 충전전력량의 연산 및 전송을 위한 메인 컨트롤러를 1곳에 설치하고, 다수의 차량에 충전하기 위한 충전케이블을 다수 마련하여 전기자동차를 충전하는 1:N 방식의 충전 시스템을 구현함으로써, 주차 공간의 사용성을 극대화할 수 있고, 충전케이블이 설치되어 있는 원하는 곳에서 충전할 수 있는 등 공간활용성을 높일 수 있고 충전의 편의성을 향상시킬 수 있는 한편, 예약 충전 기능을 통해 다수의 전기자동차를 순차적으로 충전하는 새로운 방식을 구현함으로써, 제한된 수량의 충전기로 다수의 전기자동차를 예약 순번대로 충전할 수 있다.In addition, the main controller for user authentication for charging and calculation and transmission of charging power is installed in one location, and multiple charging cables are provided to charge multiple vehicles, creating a 1:N charging system for charging electric vehicles. By implementing this, the usability of the parking space can be maximized, space utilization can be increased, such as charging at a desired location where the charging cable is installed, and charging convenience can be improved. Meanwhile, the reservation charging function can be used to increase the convenience of charging. By implementing a new method of sequentially charging electric vehicles, it is possible to charge multiple electric vehicles in scheduled order with a limited number of chargers.
그러나 상기 등록특허는 메인 컨트롤러를 중심으로 다수의 차량에 충전하기 위한 충전케이블을 다수 마련하여 전기자동차를 충전하는 1:N 방식의 충전 시스템을 구현하는 이점이 있는 반면, 메인 컨트롤러와 충전장치 간 거리가 멀 경우에는 충전제어신호인 PWM 신호의 왜곡현상으로 인하여 충전 효율이 저하되는 문제점이 있다.However, the above registered patent has the advantage of implementing a 1:N charging system for charging electric vehicles by providing a large number of charging cables for charging multiple vehicles centered on the main controller, while the distance between the main controller and the charging device is If it is too far, there is a problem that charging efficiency is reduced due to distortion of the PWM signal, which is a charging control signal.
즉 충전용 콘센트가 설치된 장소에 내연기관 혹은 다른 전기차가 주차되었을 경우 전기자동차 배터리에 연결되는 케이블의 길이가 한정되어 있어 제때 충전을 못하는 경우가 비일비재하다. In other words, when an internal combustion engine or other electric vehicle is parked in a place where a charging outlet is installed, it is not uncommon for the cable to be connected to the electric vehicle battery to be unable to be charged in a timely manner due to the limited length.
따라서 케이블 길이를 늘려도 충전제어신호의 왜곡현상이 발생하지 않는 기술을 적용할 경우, 예를 들어, 10 ~ 20m까지도 멀리 있는 충전용 콘센트에 충전기를 접속하여 충전할 수 있으므로 이러한 기술 개발이 절실한 것이 현실이다.Therefore, if a technology is applied that does not cause distortion of the charging control signal even when the cable length is increased, for example, charging can be done by connecting the charger to a charging outlet as far as 10 to 20 meters away, so the development of such technology is urgently needed. am.
본 발명의 목적은 본체와 커플러가 일체화되어 케이블의 길이를 대폭 연장할 수 있는, 충전신호의 왜곡이 발생하지 않도록 컨트롤부와 커플러가 일체화E된 충전장치를 제공하는데 있다. The purpose of the present invention is to provide a charging device in which the main body and the coupler are integrated so that the length of the cable can be significantly extended, and the control unit and the coupler are integrated to prevent distortion of the charging signal.
본 발명의 다른 목적은, 계량 및 통신 기능을 내장한 본체를 커플러에 일체화함으로써 충전시 계량 및 인증이 가능한 공용 충전기로 사용할 수 있도록 한, 충전신호의 왜곡이 발생하지 않도록 컨트롤부와 커플러가 일체화E된 충전장치를 제공하는데 있다. Another object of the present invention is to integrate the main body with built-in metering and communication functions into the coupler so that it can be used as a common charger capable of metering and authentication when charging, and to integrate the control unit and the coupler to prevent distortion of the charging signal. The goal is to provide a charging device.

본 발명의 충전신호의 왜곡이 발생하지 않도록 컨트롤부와 커플러가 일체화E된 충전장치에 따르면, 본체와 커플러가 분리되어 있는 종래 제품의 경우 본체로부터 전송되는 아날로그 충전제어신호인 PWM 제어신호가 왜곡되어 커플러에 도달함으로써 충전효율을 저하시키는데 반해, 본 발명은 본체와 커플러가 일체화되어 케이블의 길이를 대폭 연장하여도 충전효율 저하를 방지할 수 있게 된다.

본 발명은, 계량장치 및 통신장치가 내장된 본체와 충전을 위해 전기자동차배터리에 결합되는 커플러를 일체화하여, 케이블의 길이를 대폭 증가시켜도 충전효율 저하를 방지할 수 있게 된다. The present invention integrates a main body with a built-in metering device and a communication device and a coupler coupled to an electric vehicle battery for charging, making it possible to prevent a decrease in charging efficiency even if the length of the cable is significantly increased.
공용 충전기용으로 불특정 다수가 사용하는 충전기의 경우, 현재 주차장에서 주차면의 제약을 받지않아야 할 필요가 있다. 이를 해결하기 위해서는 여러 주차면을 커버할 수 있도록 해야 하며, 전기자동차에 연결되는 커플러의 케이블 길이를 길게 하여 여러 주차면에 충전이 가능하게 하도록 해야한다.In the case of chargers used by an unspecified number of people for public chargers, there is a need to not be restricted by parking space in the current parking lot. To solve this problem, it is necessary to cover multiple parking surfaces, and the cable length of the coupler connected to the electric vehicle must be lengthened to enable charging on multiple parking surfaces.
즉 개인용 충전기인 더미 케이블 타입의 충전기가 아닌 이동형 충전기에서는 반드시 커플러와 본체 일체형 구성을 통해 케이블 길이 제한으로부터 자유롭게 할 필요가 있는 것이다. In other words, in mobile chargers other than dummy cable type chargers, which are personal chargers, it is necessary to free from cable length restrictions through an integrated coupler and body configuration.
개인용 타입의 충전기는 개인이 주차한 곳에 콘센트가 있을 경우에는 언제나 충전이 가능하므로 케이블 길이로 인한 제약이 고정형 충전기인 공용 충전기에 비해 덜하다. Personal type chargers can be charged at any time as long as there is an outlet where the individual parks, so there are fewer restrictions due to cable length compared to public chargers, which are fixed chargers.
따라서 본 발명에서는 공용 충전기, 즉 회원 인증과 계량을 통해 과금이 이루어질 수 있는 충전장치를 개발하여 케이블 길이의 제약으로부터 자유워지도록 한다. Therefore, the present invention develops a public charger, that is, a charging device that allows billing through member authentication and metering to be free from cable length restrictions.

As shown in Figure 1, the charging device of the present invention includes a coupler 10 connected to an electric vehicle for charging, a main body 20 configured with a communication unit for measuring the charging amount, customer authentication, and communication with a remote control center; , and includes a cable 30 connected to a charging outlet installed at a charging station such as a parking lot.
도 2에 도시한 바와 같이, 본체(20)는 내부에 RFID 리더가 구성되어 RFID 가 인식됨으로써 회원 인증은 물론, 전기자동차(400)에 대한 충전이 개시 및 종료됨을 네트워크망을 통해 관제센터 서버(200) 및/또는 사용자 단말기(300)에도 전송하여 전기자동차(400) 충전정보의 공유가 가능하도록 할 수 있다.As shown in FIG. 2, the main body 20 is configured with an RFID reader inside, and the RFID is recognized, thereby not only authenticating members, but also starting and ending charging of the electric vehicle 400 through a control center server ( 200) and/or can be transmitted to the user terminal 300 to enable sharing of electric vehicle 400 charging information.
또한, 본체(20)는 별도로 도시하지는 않았으나, 상기 서버(200) 및/또는 단말기(300)와의 통신을 위한 통신부와, 전체적인 충전동작을 제어하는 제어부와, 충전개시로부터 완료까지의 동작수행을 위해 조작되는 조작부와, 콘센트에 대한 연결을 감지하는 감지부와, 충전 전기량 및 콘센트의 공급전력을 측정하는 측정부와, 충전이 정상적으로 이루어지지 않는 경우 경보음을 방출하는 경보부 등으로 구성될 수 있으며, 전기자동차 충전이 정상적으로 이루어지도록 하고, 충전 정보에 따른 과금 등이 합리적인 기준으로 산정되도록 서버(200) 및/또는 단말기(300)와 충전 정보를 공유할 수 있다.In addition, although not separately shown, the main body 20 includes a communication unit for communication with the server 200 and/or the terminal 300, a control unit for controlling the overall charging operation, and a control unit for performing operations from the start of charging to completion. It may be composed of a control unit that is operated, a detection unit that detects the connection to the outlet, a measuring unit that measures the amount of charging electricity and the power supplied to the outlet, and an alarm unit that emits an alarm sound when charging is not performed properly. Charging information can be shared with the server 200 and/or terminal 300 to ensure that electric vehicles are charged normally and to calculate charges based on charging information on a reasonable basis.
이와 같이 구성된 본 발명에 따르면, 충전량 측정 및 고객 인증 등이 커플러(10)와 일체로 구성된 본체(20)에 의해 이루어짐으로써 케이블(30)의 길이를 대폭 증가시키더라도 본체(20)로부터 전송되는 아날로그 충전제어신호인 PWM 제어신호가 정상적으로 커플러(10)에 도달하여 전기자동차 충전이 이루어지므로 효율적인 충전이 가능하게 된다. According to the present invention configured as described above, charging amount measurement and customer authentication are performed by the main body 20 integrated with the coupler 10, so even if the length of the cable 30 is greatly increased, the analog transmitted from the main body 20 Since the PWM control signal, which is a charging control signal, normally reaches the coupler 10 to charge the electric vehicle, efficient charging is possible.
한편, 상기 제어부에는 콘센트와 전기자동차간에 연결 가능한 케이블 길이가 미리 설정 저장되어 있는 상태에서, 케이블 길이가 일정길이 이상 증가할 때, 즉 충전신호 왜곡없이 연결 가능한 길이를 초과할 때 경보부를 통해 경보음을 발생할 수 있다. Meanwhile, in the control unit, the length of the cable that can be connected between the outlet and the electric vehicle is preset and stored, and when the cable length increases beyond a certain length, that is, exceeds the length that can be connected without distorting the charging signal, an alarm sounds through the alarm unit. may occur.
이때, 상기 연결되는 케이블 길이는 케이블이 감겨질 수 있도록 본체의 내부에 구성된 회전권선부(도시 생략)에 감겨진 상태에서 권선부의 회전수를 토대로 판단할 수 있다. 즉 사용자가 충전기를 콘센트에 연결한 상태에서 커플러를 전기자동차에 접속하는 경우, 상기 권선부가 한바퀴 회전할 때마다 인출되는 케이블 길이가 설정되어 있고, 권선부의 회전수를 감지하는 센서가 구성되어, 이 센서에서 감지된 권선부의 회전수가 제어부에 입력되면, 제어부는 센서에 의해 감지된 권선부의 회전수를 토대로 콘센트와 전기자동차간에 연결되는 케이블 길이를 실시간으로 파악할 수 있는 것이다.At this time, the length of the connected cable can be determined based on the number of rotations of the winding section while the cable is wound around a rotating winding section (not shown) configured inside the main body so that the cable can be wound. That is, when the user connects the coupler to the electric vehicle while the charger is connected to the outlet, the length of the cable drawn out each time the winding unit rotates is set, and a sensor is configured to detect the number of rotations of the winding unit. When the number of turns of the winding part detected by the sensor is input to the control unit, the control unit can determine the length of the cable connected between the outlet and the electric vehicle in real time based on the number of turns of the winding part detected by the sensor.
또한, 전기자동차에 커플러가 연결되어 충전이 수행되는 동안, 커플러의 당김으로 인하여 커플러가 전기자동차로부터 이탈되어 정상적인 충전이 불가능해질 수 있다.Additionally, while the coupler is connected to the electric vehicle and charging is performed, the coupler may be separated from the electric vehicle due to the pulling of the coupler, making normal charging impossible.
따라서 본 발명에서는 커플러와 전기자동차의 정확한 결합(접속)상태를 유지하는지를 점검할 수 있도록 센서를 커플러와 전기자동차 배터리에 각각 구성할 수 있다. 즉 전기자동차에 커플러가 접속되는 경우 서로 마주보게 되는 면에 예를 들어, 초음파센서를 설치하여 전기자동차와 커플러간 거리를 감지함으로써 그 감지된 거리에 따라 정상적인 접속 상태인지의 여부를 판단할 수 있는 것이다. Therefore, in the present invention, a sensor can be installed on the coupler and the electric vehicle battery to check whether the correct coupling (connection) state of the coupler and the electric vehicle is maintained. In other words, when a coupler is connected to an electric vehicle, for example, an ultrasonic sensor is installed on the side facing each other to detect the distance between the electric vehicle and the coupler, so that it can be determined whether the connection is normal according to the detected distance. will be.
상기 커플러와 전기자동차간 거리 판단은 제어부에 내장된 프로그램에 의해 가능하도록 구성한다.The distance between the coupler and the electric vehicle can be determined by a program built into the control unit.
상기 제어부의 판단결과, 커플러와 전기자동차간 접속이 정상적이지 못할 경우에는 경보부 등을 통해 경보음을 외부로 방출함으로써 사용자로 하여금 즉시 조치가 가능하도록 할 수 있다.As a result of the control unit's determination, if the connection between the coupler and the electric vehicle is not normal, an alarm sound can be emitted to the outside through an alarm unit, etc., allowing the user to take immediate action.
