[발명의 바람직한 형태][Preferred aspect of the invention]

본 발명은 전기자동차 충전용 젠더가 구성되는 충전장치를 개시한다.The present invention discloses a charging device comprising a gender for charging an electric vehicle.

본 발명은, 이동형 충전장치의 용량에 관계없이 일반 콘센트에도 접속 가능한 젠더로서의 기능을 갖는 전기자동차 충전용 젠더를 개시하고, 젠더를 통해 용량이 큰 이동형 충전장치를 일반 콘센트에 접속 가능하도록 함으로써, 하나의 콘센트에 여러 대의 전기자동차가 동시에 충전하는 경우 상대적으로 용량이 작은 충전장치로 충전하는 경우에 대비하여 효율적인 전력 분배가 이루어지도록 구성한다.The present invention discloses a gender for charging an electric vehicle having a function as a gender that can be connected to a general outlet regardless of the capacity of the portable charging device, and by making it possible to connect a portable charging device with a large capacity to a general outlet through the gender, one When several electric vehicles are simultaneously charged at the outlet of the , it is configured to efficiently distribute power in case of charging with a charging device with a relatively small capacity.

본 발명은, 구체적으로 3kw 충전기에 구성되는 플러그와 동일한 구조의 플러그를 7kw 충전기에 접속가능하도록 구성함으로써, 보다 효율적인 전력 분배가 가능하도록 한다.The present invention enables more efficient power distribution by configuring a plug having the same structure as a plug configured in a 3kw charger to be connectable to a 7kw charger specifically.

본 발명은, 서로 용량이 다른 충전기 종류는 그에 내장된 RFID를 통해 구분이 가능하도록 구성된다. 즉 3kw 충전기에 내장되는 RFID와, 7kw 충전기에 내장되는 RFID를 달리 구성함으로써 컨트롤러가 이를 바탕으로 전력 분배가 가능하도록 하는 것이다.According to the present invention, the types of chargers having different capacities are configured to be distinguishable through RFID embedded therein.

도 1에 도시한 바와 같이 7kw 이동형 충전장치는 전기자동차 충전을 위한 충전 컨트롤러(10)와, 상기 컨트롤러(10) 및 전기자동차에 연결되는 커넥터(20)와, 상기 컨트롤러(10) 및 외부 콘센트에 연결되는 커넥터(30)와, 상기 컨트롤러(10), 커넥터(20) 및 커넥터(30)를 전기적으로 연결하는 케이블(40)(충전라인)로 구성된다.As shown in FIG. 1, the 7kw mobile charging device includes a charge controller 10 for charging an electric vehicle, a connector 20 connected to the controller 10 and the electric vehicle, and the controller 10 and an external outlet. It is composed of a connector 30 to be connected, and a cable 40 (charging line) electrically connecting the controller 10 , the connector 20 and the connector 30 .

상기에서 7kw 이동형 충전장치라 명시하였으나, 이는 예시적인 것으로써 반드시 이러한 용량에만 국한하는 것은 아니다.Although it has been specified as a 7kw mobile charging device in the above, this is an example and is not necessarily limited to this capacity.

그런데, 7kw 이동형 충전장치는 도 2에 도시한 바와 같이 외부 콘센트에 연결되도록 커넥터(30)에 연결된 플러그(50)가 일반용 콘센트 연결용 구조가 아니고 산업용 구조로 되어 있다. However, in the 7kw mobile charging device, the plug 50 connected to the connector 30 to be connected to an external outlet is not a structure for connecting a general outlet, but an industrial structure as shown in FIG. 2 .

따라서 이러한 플러그(50)로는 일반용 콘센트에 대한 연결이 불가능하므로 상대적으로 용량이 큰 7kw 이동형 충전장치를 일반용 콘센트에 연결 가능하게 하기 위해서는 플러그(50)의 구조를 변경할 필요가 있다.Therefore, since it is impossible to connect the plug 50 to a general outlet, it is necessary to change the structure of the plug 50 in order to connect a 7kw portable charging device having a relatively large capacity to the general outlet.

본 발명은 도 3 및 도 4에 도시한 바와 같이 커넥터(30)에 연결되는 플러그를 젠더로서의 역할을 하도록 플러그(60) 또는 플러그(70)로 변형 구성하여 일반 콘센트에 대한 연결이 가능하도록 한다.3 and 4, the present invention transforms the plug connected to the connector 30 into a plug 60 or a plug 70 to serve as a gender to enable connection to a general outlet.

즉 플러그(60) 또는 플러그(70)가 전기자동차에 대한 전원 공급 젠더로서의 역할을 수행하는 것으로써, 도 5에 도시한 외부 상용전원 커넥터(콘센트)(100)와 매칭되는 포트 형태를 갖도록 구성한다.That is, the plug 60 or plug 70 serves as a power supply gender for the electric vehicle, and is configured to have a port shape that matches the external commercial power connector (outlet) 100 shown in FIG. 5 . .

예를 들어, 상용전원용 입력 젠더로서 상용전원 커넥터와 매칭되는 커넥터 단자핀 구조를 가지며, 이에 따라 상용전원 공급유닛으로부터 외부 전력을 제공받는 것이 가능하다.For example, it has a connector terminal pin structure that matches the commercial power connector as an input gender for commercial power, and thus it is possible to receive external power from the commercial power supply unit.

이와 같은 형태로 플러그(60) 또는 플러그(70)를 구성하면, 여러 가지로 다양하게 응용이 가능하다.When the plug 60 or the plug 70 is configured in this form, various applications are possible.

예를 들어, 완속용 입력 젠더라면 급속용 외부전원 공급유닛의 커넥터와 매칭되는 커넥터 단자핀 구조를 가지도록 구성할 수 있으며, 설정된 기준 속도보다 느리게 전기자동차를 충전시키는 완속용 외부전원 공급유닛으로부터 외부 전력을 제공받도록 할 수 있다.For example, if it is an input gender for slow speed, it can be configured to have a connector terminal pin structure that matches the connector of the fast external power supply unit, power can be provided.

또한, 급속용 입력 젠더라면 완속용 외부전원 공급유닛의 커넥터와 매칭되는 커넥터 단자핀 구조를 가지도록 구성할 수 있으며, 설정된 기준 속도보다 빠르게 전기자동차를 충전시키는 급속용 외부전원 공급유닛으로부터 외부 전력을 제공받도록 할 수 있다.In addition, if the input gender is for rapid use, it can be configured to have a connector terminal pin structure that matches the connector of the external power supply unit for slow speed. can be provided.

한편, 도 5에 도시한 콘센트(100)에 플러그(60) 또는 플러그(70)가 연결되어 전기자동차에 대한 충전이 수행되는 동안, 커넥터(20) 또는 커넥터(30)의 당김으로 인하여 플러그(60) 또는 플러그(70)가 콘센트(100)로부터 이탈되어 정상적인 충전이 불가능해질 수 있다.On the other hand, while the plug 60 or plug 70 is connected to the outlet 100 shown in FIG. 5 and charging for the electric vehicle is performed, the plug 60 due to pulling of the connector 20 or the connector 30 ) or the plug 70 may be separated from the outlet 100 to make normal charging impossible.

따라서 본 발명에서는 플러그(60) 또는 플러그(70)와 외부 콘센트(100)의 정확한 결합(접속)상태를 유지하는지를 점검할 수 있도록 센서를 콘센트(100) 또는 플러그(60)(70) 중 어느 하나 또는 모두에 설치할 수 있다. 즉 콘센트(100)에 플러그(60) 또는 플러그(70)가 접속되는 경우 서로 마주보게 되는 면에 예를 들어, 초음파센서를 설치하여 콘센트(100)와 플러그(60) 또는 플러그(70)간 거리를 감지함으로써 그 감지된 거리에 따라 정상적인 접속 상태인지의 여부를 판단할 수 있는 것이다. Therefore, in the present invention, any one of the outlet 100 or the plug 60 and 70 to check whether the correct coupling (connection) state of the plug 60 or the plug 70 and the external outlet 100 is maintained in the present invention. Or you can install it on all of them. That is, when the plug 60 or the plug 70 is connected to the outlet 100, for example, an ultrasonic sensor is installed on the surfaces facing each other, and the distance between the outlet 100 and the plug 60 or the plug 70 It is possible to determine whether the connection is in a normal connection state according to the sensed distance by detecting the .

상기 콘센트(100)와 플러그(60) 또는 플러그(70)간 거리 판단은 컨트롤러(10)에 내장된 프로그램에 의해 가능하도록 구성한다.The distance determination between the outlet 100 and the plug 60 or the plug 70 is configured to be possible by a program built into the controller 10 .

상기 컨트롤러(10)의 판단결과, 콘센트(100)와 플러그(60) 또는 플러그(70)간 접속이 정상적이지 못할 경우에는 경보부 등을 통해 경보음을 외부로 방출함으로써 사용자로 하여금 즉시 조치가 가능하도록 할 수 있다.As a result of the determination of the controller 10, when the connection between the outlet 100 and the plug 60 or the plug 70 is not normal, an alarm sound is emitted to the outside through an alarm unit, so that the user can take immediate action. can do.

한편, 도 1에 도시한 이동형 충전장치는 7kw용이므로 이를 일반 콘센트를 통해 전기자동차를 충전하는데 적합하도록 컨트롤러(10)가 제어하게 되며, 예를 들어, 일반 콘센트로부터 출력되는 전력이 컨트롤러(10)에 의해 조절되어 플러그(60) 또는 플러그(70)를 통해 전기자동차에 공급되게 된다. On the other hand, since the mobile charging device shown in FIG. 1 is for 7 kw, the controller 10 controls it to be suitable for charging an electric vehicle through a general outlet. For example, the power output from the general outlet is controlled by the controller 10 It is controlled by and supplied to the electric vehicle through the plug 60 or the plug 70 .

또한, 7kw 충전기에는 7kw 충전기용 RFID가 내장되고, 이를 바탕으로 컨트롤러(10)에서는 충전 콘센트에 접속된 전기자동차 대수에 따른 전력분배 동작을 수행한다. In addition, the 7kw charger has a built-in RFID for the 7kw charger, and based on this, the controller 10 performs a power distribution operation according to the number of electric vehicles connected to the charging outlet.

즉 3kw 충전기에 내장된 RFID와는 다른 RFID가 7kw 충전기에 내장되고, 컨트롤러(10)에는 이에 부합하는 전력 분배 프로그램이 내장됨으로써, 7kw 충전기가 젠더를 통해 콘센트에 접속될 경우 7kw 충전용량에 맞는 전력 분배 동작을 수행하는 것이다. That is, different RFID from the RFID built into the 3kw charger is built into the 7kw charger, and the controller 10 has a power distribution program corresponding thereto, so that when the 7kw charger is connected to the outlet through the gender, power is distributed according to the 7kw charging capacity. to perform the action.

또한, 젠더에 상기와 같은 용량 구분용 RFID를 내장하여 컨트롤러로 하여금 이를 인식하여 그에 따른 전력 분배가 가능하도록 구성할 수도 있다.In addition, by embedding the RFID for capacity classification as described above in the gender, the controller may recognize it and configure the power distribution accordingly.

컨트롤러(10)는 젠더로부터 AC 전력이 제공되는 경우, AC 전력을 AC/DC 컨버터로 스위칭한 후 DC/DC 컨버터를 거쳐서 변환되는 DC 전력을 충전 전력으로서 전기자동차에 제공한다.When AC power is provided from the gender, the controller 10 switches the AC power to the AC/DC converter and then provides the DC power converted through the DC/DC converter as charging power to the electric vehicle.

즉 젠더가 일반 콘센트에 연결된 경우, 유입되는 AC 전력을 AC/DC 컨버터로 스위칭한 후 DC/DC 컨버터를 거쳐서 변환되는 DC 전력을 충전 전력으로서 전기자동차로 제공하는 것이다. That is, when the gender is connected to a general outlet, the incoming AC power is switched to the AC/DC converter, and then the DC power converted through the DC/DC converter is provided as charging power to the electric vehicle.

또한 컨트롤러(10)는 직접 DC 전력이 제공되는 경우, DC 전력을 DC/DC 컨버터로 스위칭하여 변환되는 DC 전력을 충전 전력으로서 전기자동차로 제공하는 스위칭을 수행할 수 있다. In addition, when DC power is directly provided, the controller 10 may perform switching to provide the converted DC power to the electric vehicle as charging power by switching the DC power to the DC/DC converter.

한편, 상기 컨트롤러(10)는 내부에 RFID 리더가 구성되며, RFID는 도 5에 도시한 바와 같은 콘센트 내부에 구성되므로 컨트롤러(10)에 의해 RFID 가 인식됨으로써 전기자동차(400)에 대한 충전이 개시 및 종료됨을 도 6에 도시한 바와 같이 네트워크망을 통해 관제센터 서버(200) 및/또는 사용자 단말기(300)에도 전송하여 전기자동차 충전정보의 공유가 가능하게 된다.On the other hand, since the controller 10 has an RFID reader therein, and the RFID is configured inside the outlet as shown in FIG. 5 , the RFID is recognized by the controller 10 to start charging the electric vehicle 400 . As shown in FIG. 6 , it is also transmitted to the control center server 200 and/or the user terminal 300 through a network to enable sharing of electric vehicle charging information.

상기 컨트롤러(10)는 도시하지는 않았으나, 상기 서버(200)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 구성되어 전기자동차 충전이 정상적으로 이루어지도록 하고, 충전 정보에 따른 과금 등이 합리적인 기준으로 산정되도록 서버(200) 및/또는 단말기(300)와 충전 정보를 공유한다.Although not shown, the controller 10 includes a communication unit for communication with the server 200, a control unit for controlling the overall charging operation, an operation unit operated to perform operations from charging start to completion, and a connection to an outlet It consists of a sensing unit that detects the electric vehicle, a measuring unit that measures the amount of charging electricity and power supplied by the outlet, and an alarm unit that emits an alarm sound when charging is not performed normally. The charging information is shared with the server 200 and/or the terminal 300 so that billing is calculated based on a reasonable standard.

상기와 같은 컨트롤러와 전기자동차 충전에 따른 과금시스템 등의 구성은 본원 출원인의 특허등록 제10-1754139호(전기자동차 충전 및 과금시스템), 특허등록 제10-1769467호(전기자동차 충전 및 과금시스템), 특허등록 제10-1769466호(온도에 따라 충전을 제어하는 전기자동차 충전 및 과금시스템) 등에 일부 나타나 있다.The configuration of the charging system according to the controller and electric vehicle charging as described above is the applicant's patent registration No. 10-1754139 (electric vehicle charging and billing system), patent registration No. 10-1769467 (electric vehicle charging and charging system) , Patent Registration No. 10-1769466 (electric vehicle charging and billing system that controls charging according to temperature), etc.

한편, 상기 서버(200)에서는 복수 개의 접속구가 구성된 콘센트에 복수 개의 이동형 충전장치가 접속되어 전기자동차(400)를 충전할 때, 이동형 충전장치 각각의 총 충전 용량을 계산하여 그 합산값이 전력회사 계량기의 계약 전력 용량의 범위내에서 구동되도록 조절하게 된다. On the other hand, in the server 200, when a plurality of mobile charging devices are connected to an outlet configured with a plurality of connection ports to charge the electric vehicle 400, the total charging capacity of each of the mobile charging devices is calculated and the sum is calculated by the power company. It is controlled to operate within the range of the contract power capacity of the meter.

예를 들어, A아파트 101동 지하 2층 A구역 주차장에 설치된 전력회사 계약 용량이 9kw인 계량기 라인에 커넥터가 4개가 설치되어 있다고 가정한다.For example, it is assumed that 4 connectors are installed on a meter line with a contracted capacity of 9 kw installed in the parking lot of Area A on the 2nd basement floor of Building A of Apartment A.

만일 3명이 동시에 사용할 경우, 용량이 7kw인 충전장치가 접속되더라도 한 대의 자동차당 3kw씩 줄일 수도 있고, 처음 한 대의 자동차가 7kw로 충전하다가 두번 째 자동차가 사용 개시하면 4.5kw씩 나누었다가, 세번 째 자동차가 사용하면 각각 3kw 씩 나누어 충전할 있도록 구현할 수 있다. If 3 people use it at the same time, even if a charging device with a capacity of 7kw is connected, it can be reduced by 3kw per vehicle. When a car uses it, it can be implemented so that it can be charged by dividing it by 3kw each.

이때, 요금제 가격 및 고객 충전량 등에 따라 각각 다른 충전 속도로 충전하도록 제어할 수도 있다. In this case, it is also possible to control the charging rate to be charged at different charging rates according to the rate plan price and customer charging amount.
