본 발명은 전기 자동차 충전 시스템에 관한 것으로서, 보다 구체적으로는 전기 자동차를 무접점 방식으로 충전하는 시스템에 관한 것이다. The present invention relates to an electric vehicle charging system, and more particularly to a system for charging an electric vehicle in a contactless manner.

산업이 발달함에 따라 에너지 사용이 증가되고 있는 반면, 에너지 자원은 한정되어 있어 여러 재생에너지에 대한 관심이 부각되고 있다. While the use of energy is increasing as the industry develops, energy resources are limited, and interest in various renewable energies is increasing.

자동차 분야에서도 기존 엔진 자동차의 경우 매연 등의 발생으로 인한 환경오염 문제가 부각되고 있으며 이와 동시에 고유가로 인하여 운전자가 많은 부담을 가지게 된다. In the field of automobiles, the problem of environmental pollution due to the generation of smoke, etc. in the existing engine cars is highlighted, and at the same time, the driver has a lot of burden due to high oil prices.

이러한 문제를 해결하기 위하여, 하이브리드 형태 즉 엔진 및 모터가 병용되는 하이브리드 자동차가 제시되고 있으며 모터만에 의한 전기 자동차도 제시되고 있다. In order to solve this problem, a hybrid vehicle in which a hybrid type, that is, an engine and a motor are used together, has been proposed, and an electric vehicle based only on a motor has been proposed.

그러나, 이러한 하이브리드 자동차 또는 전기 자동차의 배터리를 충전하기 위해서는 정해진 장소(충전소)의 정해진 위치에 정차한 뒤 유선 플러그를 전기 자동차에 삽입하여 충전할 수 밖에 없어 불편하였다. However, in order to charge the battery of such a hybrid vehicle or an electric vehicle, it is inconvenient to stop by inserting a wired plug into an electric vehicle after stopping at a predetermined position of a predetermined place (charging station).

이를 해결하기 위하여 비접촉 방식의 충전방식이 개발되고 있으나 휴대폰이나 기타 휴대 전자기기와 같이 소형인 경우에는 간단하게 충전패드에 올려놓으면 되나 자동차와 같은 대형의 경우에는 비접촉 방식의 충전 시스템을 적용하는 것에 많은 한계가 있었다.
In order to solve this problem, a non-contact charging method has been developed. However, in the case of a small phone such as a mobile phone or other portable electronic device, the charging pad can be simply placed on a charging pad. There was a limit.

According to the present invention as described above, by minimizing the separation distance between the charging unit provided on the bottom of the electric vehicle and the charging pad provided on the ground can not only increase the charging efficiency but also ultimately reduce the charging time.

이하, 본 발명의 바람직한 실시예에 의한 전기 자동차 충전 시스템에 대하여 설명한다. Hereinafter, an electric vehicle charging system according to a preferred embodiment of the present invention will be described.

본 발명의 바람직한 실시예에 의한 전기 자동차 충전 시스템은, 충전 유닛, 충전 패드 및 전원 공급부를 포함한다. An electric vehicle charging system according to a preferred embodiment of the present invention includes a charging unit, a charging pad and a power supply.

충전 유닛은, 전기 자동차의 배터리와 전기적으로 연결되며, 상기 전기 자동차의 하부 외부에 돌출되게 자기코일이 마련된다.
The charging unit is electrically connected to a battery of the electric vehicle, and a magnetic coil is provided to protrude outside the lower portion of the electric vehicle.

충전 패드는, 주차장이나 충전소 등과 같은 구역의 지면에 설치되며, 상기 충전 유닛과 전자기 유도효과를 발생시키기 위하여 자기코일이 마련되며, 충전 패드는 외부 전원 공급부에 의하여 전류가 인가되어 최종적으로 충전 유닛과의 상호 관계에 의하여 전자기 유도현상이 발생되어 충전 유닛의 자기 코일에 전류가 흐르고 이러한 전류에 의하여 전기적으로 연결되는 전기 자동차의 배터리가 충전되게 된다.
The charging pad is installed on the ground of an area such as a parking lot or a charging station, and a magnetic coil is provided to generate an electromagnetic induction effect with the charging unit. The charging pad is supplied with an electric current by an external power supply, and finally the charging unit and The electromagnetic induction phenomenon is generated by the mutual relationship of the electric current flowing through the magnetic coil of the charging unit and the battery of the electric vehicle electrically connected by the current is charged.

이때, 전기 자동차는 지면에 상당한 거리로 이격되게 되는데 이러한 이격거리로는 효율적으로 전기 자동차를 비접촉 방식으로 충전하기에는 무리가 있기 때문에, 지면 즉 충전 패드와 전기 자동차 저면 즉 충전 유닛관 이격거리를 최소화할 필요가 있다. At this time, the electric vehicle is spaced at a considerable distance to the ground, but since such a distance is difficult to efficiently charge the electric vehicle in a non-contact manner, the distance between the ground, that is, the charging pad and the bottom of the electric vehicle, that is, the charging unit tube is minimized. There is a need.

이를 해결하기 위하여, 본 발명의 바람직한 실시예에 의하면 충전 유닛이 충전 패드측으로 선택적으로 하강되도록 구성하거나, 충전 패드가 충전 유닛측으로 선택적으로 상승되도록 구성하거나 충전 패드 및 충전 유닛 쌍방이 상호 접근하도록 구성한다. In order to solve this problem, according to a preferred embodiment of the present invention, the charging unit is configured to be selectively lowered to the charging pad side, or the charging pad is configured to be selectively raised to the charging unit side, or both the charging pad and the charging unit are configured to approach each other. .

이러한 구성에 의하여 비접촉 이격거리를 최소화하여 충전효율을 증가시킬 수 있을 뿐만 아니라 궁극적으로 충전시간도 줄일 수 있게 된다.
This configuration can minimize the non-contact separation distance to increase the charging efficiency and ultimately reduce the charging time.

이때, 전기 자동차가 충전 패드위로 즉 주차 구역에 진입하여 정차하였는지 판단하는 센서부가 더 설치되는 것이 바람직하며, 센서부에 의하여 전기 자동차가 인식되면 자동으로 충전패드, 충전 유닛 또는 충전패드 및 충전 유닛이 상하 구동되게 하는 것도 바람직하며, 이와 달리 운전자의 조작에 의하여 충전패드, 충전 유닛 또는 충전패드 및 충전 유닛이 상하 구동되게 구성할 수 있다. In this case, it is preferable that the sensor unit is further installed to determine whether the electric vehicle has stopped on the charging pad, that is, entering the parking area. When the electric vehicle is recognized by the sensor unit, the charging pad, the charging unit or the charging pad, and the charging unit are automatically installed. It is also preferable to be driven up and down, and alternatively, the charging pad, the charging unit or the charging pad and the charging unit may be configured to be driven up and down by a driver's operation.

상기 전기 자동차의 주차구역 진입여부를 검지하는 센서부는, 촬상 카메라를 이용하여 전기 자동차를 식별하거나, 광센서를 이용하여 감지하거나, 압력센서를 이용하여 전기 자동차의 하중을 인식하는 구성을 가질 수 있으며, 이러한 예에 한정되지 않고 자동차가 진입되는지 여부를 판단할 수 있으면 어느 형태의 센서가 마련되어도 무방하며, 충전 패드측 또는 차량 또는 제 3의 위치에 설치 가능하다.The sensor unit detecting whether the electric vehicle enters a parking area may have a configuration of identifying an electric vehicle using an imaging camera, sensing using an optical sensor, or recognizing a load of the electric vehicle using a pressure sensor. However, the present invention is not limited to this example, and any type of sensor may be provided as long as it is possible to determine whether the vehicle enters the vehicle.

그리고 충전 패드와 충전 유닛의 형상에 있어서는 기존의 단순한 평면 형태의 패드 및 충전 유닛이 아니라, 일측이 타측에 일정 부분 삽입되는 듯한 체결 방식이 가능한 형상의 패드 및 유닛은 효율의 측면 뿐 나이라 유해성 최소화 간점에서 바람직하다. 이때, 일측이 타측에 삽입될 때 타측에는 일측이 삽입되는 공간이 마련될 수 있으며, 이와 달리 타측의 삽입 공간을 커버링하는 커버부재가 설치되어 평상시에는 외부 이물질 등이 끼는 것을 방지하고 실제 충전이 이루어질 때 즉, 일측이 타측으로 삽입되면서 커버부재를 가압되는 방향으로 이동가이드되게 설치하는 것도 가능하다. 이때, 커버부재는 일측에 의한 가압이 해제될 때 즉, 충전이 완료되는 경우 원상회복되도록 구성하는 것이 바람직하다. In addition, in terms of the charging pad and the charging unit, pads and units having a fastening method in which one side is partially inserted into the other side, rather than the conventional simple flat pad and charging unit, are minimal in terms of efficiency because of their efficiency. It is preferable at a point. In this case, when one side is inserted into the other side, a space into which one side is inserted may be provided on the other side. In contrast, a cover member covering the insertion space of the other side may be installed to prevent external foreign substances, etc., from being caught in the ordinary and the actual filling may be made. That is, when one side is inserted into the other side, it is also possible to install the cover member to move in the direction of the pressing. At this time, the cover member is preferably configured to restore the original state when the pressure is released by one side, that is, when the filling is completed.

또한 충전 패드와 충전 유닛은 두 장치간의 적절한 위치적 부합을 위하여 수직 운동 뿐 아니라 수평 운동이 가능하도록 설계되어 어느 일방 또는 쌍방이 수직(Z방향) 및 수평(X,Y 방향)하여 가장 이상적인 위치 이동이 가능하도록 함이 바람직하다.In addition, the charging pad and the charging unit are designed to allow horizontal movement as well as vertical movement for proper positional matching between the two devices, so that one or both of them can move vertically (Z direction) and horizontal (X, Y direction) to move the most ideal position. It is desirable to make this possible.

상기에서는 지면에 설치되는 충전 패드, 전기 자동차의 저면에 설치되는 충전 유닛이 상하 구동되는 구성에 대하여 설명하였으나, 이와 달리 즉, 상하 구동되지 않고 지면을 상측으로 돌출되게 형성하고 충전 패드가 설치되게 구성하는 것도 무방하며, 이때 상측으로 돌출되는 지면의 형상은 전기 자동차의 진입 및 진출을 용이하게 하도록 진입측 및 진출측을 차량의 주행방향으로 경사지게 형성하는 것이 바람직하다. In the above description, a configuration in which the charging pad installed on the ground and the charging unit installed on the bottom of the electric vehicle is vertically driven is described above. In other words, the charging pad is formed to protrude upward and the charging pad is not installed vertically. In this case, it is preferable that the shape of the ground protruding upwards is formed such that the entry side and the exit side are inclined in the driving direction of the vehicle to facilitate the entry and exit of the electric vehicle.

또한, 본 발명의 바람직한 실시예에 의하면 전기 자동차의 충전이 완료된 경우 상하 구동된 충전 유닛 및 충전 패드가 원상태로 복귀하도록 하기 위하여, 전기 자동차 배터리의 충전잔량 또는 충전용량에 대한 정보를 충전 패드 측으로 전송하는 송신부를 더 포함한다. 송신부 측에서 배터리의 충전이 완료되었다는 신호가 전송되면 충전 패드 또는 충전 유닛을 원위치로 복귀 구동시킨다.In addition, according to a preferred embodiment of the present invention, when the charging of the electric vehicle is completed, in order to return the vertically-driven charging unit and the charging pad to the original state, transmitting information on the remaining charge or the charging capacity of the electric vehicle battery to the charging pad side The transmitter further includes a transmitter. When a signal indicating that the charging of the battery is completed is transmitted from the transmitter, the charging pad or the charging unit is driven back to its original position.

한편 수신부를 마련하여 차량의 정 위치 정차 여부 및 충전 상태 이상 유무 충전에 따른 비용 정산 관련 정보 등을 패드 측으로부터 전달 받도록 함이 바람직한 구현의 예라 할 수 있다. On the other hand, it may be an example of a preferred implementation to provide a receiving unit to receive information related to the cost settlement according to whether or not the vehicle stops in position and the state of charge abnormality from the pad side.

또한, 전기 자동차의 시동이 걸리거나 액셀레이터가 가압되는 것을 시그널로 하여 충전 패드 또는 충전 유닛을 원위치 복귀 구동시키도록 구성하거나, 운전자의 조작에 의하여 원위치 복귀 구동시키도록 구성하는 것도 무방하나, 조작에 의하여 원위치 복귀 구동시키는 구성인 경우 다른 지면 장애물에 의하여 충전 패드 또는 충전 유닛이 파손될 위험이 있으므로 별도 조작없이는 전기 자동차가 진출하지 못하도록 안전장치가 마련되는 것이 바람직하다.Further, the charging pad or the charging unit may be configured to return to the home position by a signal that the electric vehicle is started or the accelerator is pressed, or may be configured to return to the home position by the driver's operation. In the case of the return-driven configuration, since the charging pad or the charging unit may be damaged by other ground obstacles, it is preferable that a safety device is provided to prevent the electric vehicle from entering without a separate operation.

나아가 충전 유닛 및 충전 패드의 한 편 또는 양 측에 근접 거리 센서 또는 차량의 세이프티 원도우와 같은 기능을 통해서 두 장치간 불필요한 충돌을 방지하고 장치 사이에 제 3의 물체의 존재 여부를 확인하거나 또는 충돌시 즉각적인 복귀가 가능하도록 함은 안전의 관점에서 바람직하다. Furthermore, functions such as proximity sensors on one or both sides of the charging unit and the charging pad or the safety window of the vehicle prevent unnecessary collisions between the two devices and confirm the presence or absence of a third object between the devices. It is desirable from a safety point of view that an immediate return is possible.

이상, 본 발명을 본 발명의 원리를 예시하기 위한 바람직한 실시예와 관련하여 도시하고 설명하였으나, 본 발명은 그와 같이 도시되고 설명된 그대로의 구성 및 작용으로 한정되는 것이 아니다. 오히려 첨부된 특허청구범위의 사상 및 범위를 일탈함이 없이 본 발명에 대한 다수의 변경 및 수정이 가능함을 당업자While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Rather, many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.
