Description

전기자동차 배터리 충전장치{Battery Charging Apparatus for Electric Vehicle}Battery Charging App for Electric Vehicles {Battery Charging Apparatus for Electric Vehicle}

본 발명은 전기자동차의 배터리를 충전하기 위한 장치에 관한 것이다.The present invention relates to an apparatus for charging a battery of an electric vehicle.

전기자동차는 배터리를 주기적으로 충전하여야 하는데, 충전 장치는 크게 컨덕티브 전기 입력 방식과 인덕티브 전기입력 방식 두 가지가 있다. 이것은 SAE J1772, SAE J1773에 규정되어 있다. 또한 SAE J2293, IEC 61851등에도 규정되어 있다.Electric vehicles need to be charged periodically, and there are two types of charging devices, a conductive electric input method and an inductive electric input method. This is specified in SAE J1772, SAE J1773. It is also specified in SAE J2293, IEC 61851, etc.

현재 생산중이거나 개발중인 전기자동차의 배터리를 충전하는 방법은 컨덕티브 전기 입력 방식이 최초로 사용되고 있다. 컨덕티브 방식의 경우에는 비가오는 공간등에 전기 자동차가 있을 경우, 수분이나 눈등으로 인하여 충전하기 곤란한 측면이 있어 최근에는 인덕티브 충전 전기 입력 방식을 사용하려는 시도가 있다. 따라서 향후에는 전기자동차의 배터리를 충전하는 방식은 두 가지 모두 사용될 것이다.The first method of charging a battery of an electric vehicle, which is being produced or under development, is a conductive electric input method. In the case of the conductive method, when there is an electric vehicle in a rainy space or the like, there is a side that is difficult to charge due to moisture or snow, etc. Recently, there has been an attempt to use an inductive charging electric input method. Therefore, in the future, both methods of charging the battery of an electric vehicle will be used.

따라서 본 발명의 목적은 컨덕티브 전기입력 충전방식과 인덕티브 전기입력 충전방식 2가지 모두 사용하여 전기자동차 배터리를 충전할 수 있는 수단을 제공하고자 함에 있다.Accordingly, an object of the present invention is to provide a means for charging an electric vehicle battery using both a conductive electric input charging method and an inductive electric input charging method.

전기자동차의 배터리 충전방식인 인덕티브 전기입력 충전 및 컨덕티브 전기입력 충전등 두 가지 충전방식 모두를 사용할 수 있게 하고자 한다. 이를 위하여 도1에서와 같이 컨덕티브 전기 입력과 인덕티브 전기 입력등 두 가지 외부전원을 최종적으로 외부전원 선택부에 입력되도록 하였다. 입력 되는 전기의 종류에 따라 외부전원 선택부는 도2에서와 같이 인덕티브 전기가 입력될 경우에는 인덕티브 전기 개폐수단과 컨덕티브 전기 우선 선택수단을 거쳐 인덕티브 방식으로 입력된 전기가 배터리에 입력된다. 컨덕티브 입력방식 전기가 입력될 경우에는 컨덕티브 전기 우선 선택수단에 의하여 인덕티브 전기공급이 차단되고 컨덕티브 전기 개폐 수단을 통하여 컨덕티브 방식으로 입력된 전기가 배터리에 공급된다. 또한 배터리 충전 전류의 크기가 매우 크다. 개폐 수단의 접점 안전을 위하여 전기의 개폐수단은 도3에 표시한 바와 같이 전기의 ON시 도4에 표시한 바와 같이 일정시간 지연 후 ON이 되도록 하는 것을 특징으로 한다.We will be able to use both charging methods such as inductive electric input charging and conductive electric input charging. To this end, as shown in FIG. 1, two external power sources such as a conductive electric input and an inductive electric input are finally input to the external power selector. According to the type of electricity input, when the inductive electricity is input as shown in FIG. 2, the inductive electricity input means is input to the battery through the inductive electrical switching means and the conductive electrical priority selection means. . When the conductive input method electricity is input, the inductive electricity supply is cut off by the conductive electric priority selection means, and the electricity input in the conductive manner through the conductive electric opening and closing means is supplied to the battery. In addition, the battery charge current is very large. For the contact safety of the switchgear means that the switchgear of the electric is turned on after a predetermined time delay as shown in FIG.

본 발명으로 전기자동차의 배터리 충전은 비가 내리는 실외장소에서는 안전한 인덕티브 전기 입력방식을 사용할 수 있고, 가정등 건물 실내에서는 효율이 높은 컨덕티브 전기 입력 방식을 사용할 수 있어 안전하고 편리하게 배터리를 충전할 수 있게 된다. 만약 두 가지 입력 방식이 동시에 접속될 경우에는 자동적으로 컨덕티브 전기 입력 방식이 동작 된다.In the present invention, the battery charging of the electric vehicle can use a safe inductive electric input method in outdoor places where rain falls, and can use a high-efficient conductive electric input method indoors in buildings such as homes to safely and conveniently charge the battery. It becomes possible. If the two input methods are connected at the same time, the conductive electric input method is automatically activated.

본 발명에 따른 전기 자동차 배터리 충전 장치의 실시예에 관하여 설명하면 다음과 같다.Referring to the embodiment of the electric vehicle battery charging device according to the present invention.

본 발명에 따른 전기 자동차 배터리 충전 장치의 특징 및 장점들은 이하의 각 실시 예에 대한 설명을 통해 명백해질 것이다.Features and advantages of the electric vehicle battery charging device according to the present invention will become apparent from the description of each of the following embodiments.

도 1은 본 발명에 따른 전기 자동차 충전장치의 구성도이다. 전자기유도 방식을 이용하여 전기를 공급할 수 있는 인덕티브 전기 입력부(10)과 전원 콘센트에 플러그를 꼽아서 직접연결하여 사용하는 컨덕티브 전기입력부(15)로 구성된다. 인덕티브 전기입력부(10)을 통하여 입력되는 전기는 AC/DC변환부(11)를 거쳐 직류로 변환된 전기는 출력전압 스위칭 제어장치(13)에 의하여 변압기(12)를 통하여 정해진 크기의 전압으로 변화되고, AC/DC변환(14)부를 커쳐 외부전원선택부(16)에 연결된다. 컨덕티브 전기 입력 방식을 사용할 경우, 컨덕티브 전기입력부(15)를 통하여 입력되는 전기도 외부 전원 선택부(16)에 연결된다.1 is a block diagram of an electric vehicle charging device according to the present invention. It consists of an inductive electrical input unit 10 that can supply electricity using an electromagnetic induction method and a conductive electrical input unit 15 that is directly connected by plugging in a power outlet. Electricity inputted through the inductive electric input unit 10 is converted into direct current through the AC / DC conversion unit 11 to a voltage having a predetermined size through the transformer 12 by the output voltage switching control device 13. And is connected to the external power source selector 16 by extending the AC / DC converter 14. When the conductive electric input method is used, electricity input through the conductive electric input unit 15 is also connected to the external power source selector 16.

외부 전원선택부(16)에서는 입력될 수 있는 두 가지 전기중 한 가지를 선택하여 배터리(17)에 충전용 전기를 공급하게 구성된다.The external power selector 16 selects one of two types of electricity that can be input to supply charging electricity to the battery 17.

도 2에서 외부전원 선택부(16)는 인덕티브 전기 개폐 수단(21), 인덕티브 전기 차단 수단(23), 컨덕티브 전기 개폐 수단(22)으로 구성된다. 개폐수단의 실시예는 릴레이, 반도체 스위칭 소자등도 사용될 수 있다. 컨덕티브 전기가 인덕티브 전기보다 효율이 높기 때문에 컨덕티브 전기가 공급될 경우에는 인덕티브 전기공급 수단을 통한 전기공급을 차단하기 위하여 인덕티브 전기 차단부(23)가 인덕티브전기 입력을 차단한다. 인덕티브 전기 입력 차단 신호는 컨덕티브 전기가 입력되면 자동적으로 발생된다.In FIG. 2, the external power source selection unit 16 includes an inductive electrical switching means 21, an inductive electrical blocking means 23, and a conductive electrical switching means 22. Embodiments of the switching means may also be used relays, semiconductor switching elements and the like. Since the conductive electricity is more efficient than the inductive electricity, when the conductive electricity is supplied, the inductive electrical breaker 23 blocks the inductive electrical input to cut off the electricity supply through the inductive electrical supply means. The inductive electrical input blocking signal is automatically generated when the conductive electrical power is input.

도 2에서 사용되는 전기개폐 수단(21, 22, 23)들과 전기입력부 커넥터 접점에는 On/Off시 접점에 많은 전류가 흐르고 ON/OFF시 접접을 손상시킬 수도 있어 회로를 보호하기 위하여 도 3에 표시한 바와 같이 전기개폐수단(31)은 ON시간지연수단(30)에 의하여 개폐가 지연되어 ON되게 구성되어 있고, 도 4에서 지연 타이밍을 표시하였다.In order to protect the circuit, a large amount of current flows in the contacts at the time of on / off and the contacts at the time of on / off and the electrical switch means 21, 22, and 23 used in FIG. As shown, the electric switch 31 is configured to be turned on and off by the ON time delay means 30, and the delay timing is shown in FIG.

컨덕티브: 전기를 직접 도선을 이용하여 연결하여 사용하는 경우
인덕티브: 전기를 직접 연결하지 않고 전자기유도에 의한 유도 전압을 이용하여 사용하는 경우

Conductive: When electricity is connected by direct wire
Inductive: In case of using induction voltage by electromagnetic induction without directly connecting electricity
External power selector: This function selects one of two types of electricity supplied from the outside of the vehicle to charge the battery of the electric vehicle.
