Description

복수의 전기자동차에 대해 유선 및 무선 충전수단을 동시에 제공하는 전기자동차 충전장치 {ELECTRIC VEHICLE CHARGING DEVICE FOR PROVIDING WIRE AND WIRELESS CHARGING MEANS}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vehicle charging device for providing a wired and wireless charging means to a plurality of electric vehicles simultaneously.

본 발명은 전기자동차의 충전기술에 관한 것이다.The present invention relates to a charging technique for an electric vehicle.

전기자동차는 배터리에 저장된 전기에너지를 이용하여 주행하는 자동차이다. 전기자동차의 배터리를 충전하는 기술로는 유선충전과 무선충전이 있다.An electric vehicle is an automobile that travels using electric energy stored in a battery. Wired charging and wireless charging are the technologies that charge electric cars' batteries.

유선충전기술은 충전장치의 충전케이블을 직접 전기자동차에 연결한 후 배터리를 충전하는 방법이고, 무선충전기술은 직접적인 케이블 연결없이 전기에너지를 전달하는 방법이다. 예를 들어 대한민국 특허등록공보 제10-1132770호는 유선충전기술과 그에 대한 과금에 대해 개시한다.Wired charging technology is a method of connecting a charging cable of a charging device directly to an electric vehicle and then charging the battery. Wireless charging technology is a method of transferring electric energy without direct cable connection. For example, Korean Patent Registration No. 10-1132770 discloses wired charging technology and charging thereof.

그런데 종래기술에 따르면 하나의 충전장치는 유선충전 또는 무선충전만 가능했다. 따라서, 충전장소를 유선 또는 무선으로 구분해야만 했고, 이에 따라 부지선정과 장비설치에 관한 비용이 증가하는 문제가 발생했다.However, according to the prior art, one charging device was only capable of wired charging or wireless charging. Therefore, the charging site had to be classified as either wired or wireless, which resulted in increased costs for site selection and equipment installation.

본 발명의 발명가는 이러한 문제점들을 해결할 수 있는 기술을 완성하기 위하여 오랫동안 연구 노력한 끝에 본 발명을 완성하기에 이르렀다.The inventor of the present invention has accomplished the present invention after a long research effort in order to complete the technology capable of solving these problems.

본 발명의 목적은 복수의 전기자동차에 대해 유선 및 무선 충전수단을 동시에 제공하는 전기자동차 충전장치를 제공하는 것에 있다.It is an object of the present invention to provide an electric vehicle charging apparatus which simultaneously provides wired and wireless charging means for a plurality of electric vehicles.

한편, 본 발명의 명시되지 않은 또 다른 목적들은 하기의 상세한 설명 및 그 효과로부터 용이하게 추론할 수 있는 범위 내에서 추가적으로 고려될 것이다.On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

위와 같은 목적을 달성하기 위해 본 발명은 전기자동차를 유선으로 충전하는 유선충전부;According to an aspect of the present invention, there is provided an electric vehicle including: a wire charging unit for charging an electric vehicle with wires;

전기자동차를 무선으로 충전하는 적어도 하나 이상의 무선충전부;At least one wireless charging unit charging wirelessly the electric vehicle;

외부 분전반으로부터 전력을 공급받아 상기 유선충전부 및 무선충전부에 전력을 제공하는 컨버터; 및A converter that receives power from an external distribution board and provides power to the wired and wireless charging units; And

복수의 전기자동차를 충전할 때 유선충전부 및 무선충전부에 할당되는 전력량을 제어하는 제어부를 포함하는 것을 특징으로 하는 복수의 전기자동차에 대해 유선 및 무선 충전수단을 동시에 제공하는 전기자동차 충전장치를 제공한다.And a control unit for controlling the amount of electric power allocated to the wire-charging unit and the wireless-charging unit when charging the plurality of electric vehicles, the electric vehicle charging apparatus comprising: .

바람직한 실시예에서 본 발명의 제어부는 상기 컨버터를 통해 충전되는 전기자동차의 개수가 단수에서 N개(단, N은 2 이상의 정수)로 전환될 때, 상기 컨버터의 최대용량을 N분하여 각각의 충전부로 전달하도록 제어하는 것이 좋다.In a preferred embodiment of the present invention, when the number of electric vehicles to be charged through the converter is switched from N to N (where N is an integer equal to or greater than 2) As shown in FIG.

바람직한 실시예에서 본 발명의 제어부는 제2항의 초기 전력분배 이후에 복수의 충전부를 통해 충전되는 전력량을 모니터링하여,In a preferred embodiment, the control unit of the present invention monitors the amount of power charged through a plurality of charging units after the initial power distribution of claim 2,

어느 하나의 충전부를 통해 충전되는 전력량이 감소하면,When the amount of electric power to be charged through any one charging part decreases,

다른 하나의 충전부를 통해 충전되는 전력량을 증가시키는 것이 좋다.It is preferable to increase the amount of electric power charged through the other charging section.

위와 같은 본 발명에 따르면, 유선충전을 위한 주차구역과 무선충전을 위한 주차구역을 별도로 분리하지 않아도 되므로 장소확보를 위한 비용 등을 절감시킬 수 있다.According to the present invention as described above, it is not necessary to separately separate the parking area for wired charging and the parking area for wireless charging, so that the cost for securing a place can be reduced.

또한, 하나의 충전장치로 유선충전하거나 무선충전할 수 있으므로 유무선충전장치를 각각 설치하는 것에 비해 비용이 절약되는 효과가 있다.In addition, since one charging device can be wired or wirelessly charged, it is possible to save the cost compared with the case where the wired / wireless charging devices are respectively installed.

이하, 첨부된 도면을 참조하여 본 발명의 실시를 위한 구체적인 내용을 설명한다. 그리고 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.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

본 발명은 하나의 전기자동차 충전장치를 이용하여 복수의 전기자동차를 충전한다. 충전수단으로는 유선 및 무선 충전수단을 동시에 제공한다. 하나의 충전장치를 통해 복수의 전기자동차를 충전하기 때문에 충전장치의 최대충전용량을 적절하게 분배해야한다. 이하에서 이를 구체적으로 설명한다.The present invention charges a plurality of electric vehicles using one electric vehicle charging apparatus. And the wired and wireless charging means are simultaneously provided as the charging means. It is necessary to appropriately distribute the maximum charging capacity of the charging apparatus because the plurality of electric vehicles are charged through one charging apparatus. This will be described in detail below.

도 1은 본 발명에 따른 전기자동차 충전장치의 사용상태도를 나타내는 도면이다.1 is a view showing a state of use of an electric vehicle charging apparatus according to the present invention.

도 1에서 알 수 있듯이, 본 발명의 전기자동차 충전장치(200)는 전기자동차를 유선으로 충전하는 유선충전부(210), 전기자동차를 무선으로 충전하는 적어도 하나 이상의 무선충전부(220), 및 복수의 차량(11, 12, 13)에 대해 충전 중일 때 유선충전부(210) 및 무선충전부(220)에 할당되는 전력량을 제어하는 제어부(230)를 포함한다.As shown in FIG. 1, the electric vehicle charging apparatus 200 of the present invention includes a wire charging unit 210 for charging an electric vehicle with wire, at least one wireless charging unit 220 for charging the electric vehicle wirelessly, And a control unit 230 for controlling the amount of electric power allocated to the wired charging unit 210 and the wireless charging unit 220 when the vehicle 11, 12, 13 is being charged.

이와 같은 구성에 따라 전기자동차 충전장치(200)는 복수의 전기자동차(11, 12, 13)를 유선 및/또는 무선으로 충전할 수 있다. 즉, 하나의 충전장치(200)는 1번 전기자동차(11), 2번 전기자동차(12), 3번 전기자동차(13)를 동시에 충전할 수 있다. According to this configuration, the electric vehicle charging apparatus 200 can charge a plurality of electric vehicles 11, 12, 13 by wire and / or wirelessly. That is, one charging device 200 can charge the first electric car 11, the second electric car 12, and the third electric car 13 simultaneously.

도 2는 본 발명에 따른 전기자동차 충전장치의 바람직한 실시예를 나타내는 도면이다.2 is a view showing a preferred embodiment of an electric vehicle charging apparatus according to the present invention.

도 2에서 알 수 있듯이, 본 발명의 충전장치(200)는 분전반(20)으로부터 전력을 공급받는다. 공급된 전력은 컨버터(240)를 통해 유선충전규격 또는 무선충전규격에 맞는 전력으로 변환된다. 컨버터(240)에서 출력된 전력은 유선충전케이블(211), 복수의 무선충전패드(221, 222)를 통해 전기자동차에 전달된다.2, the charging apparatus 200 of the present invention receives power from the distribution board 20. As shown in FIG. The supplied power is converted through the converter 240 into a power conforming to a wired charging standard or a wireless charging standard. The power output from the converter 240 is transmitted to the electric vehicle through the wired charging cable 211 and the plurality of wireless charging pads 221 and 222. [

제어부(230)는 복수의 전기자동차를 충전할 때 유선충전부 및 무선충전부에 할당되는 전력량을 제어한다. 하나의 차량을 충전할 때는 충전장치(200)의 최대출력과 충전표준, 그리고 전기자동차의 잔여 배터리 량과 같은 사항들을 고려하여 충전하면 된다. 그러나, 하나의 충전장치를 이용하여 복수의 전기자동차를 충전할 때는 각 전기자동차에 할당되는 전력량을 적절하게 분배해야한다.The controller 230 controls the amount of electric power allocated to the wired and wireless chargers when charging the plurality of electric vehicles. When charging a single vehicle, charging may be performed taking into consideration factors such as the maximum output of the charging device 200, the charging standard, and the remaining battery capacity of the electric vehicle. However, when charging a plurality of electric vehicles using one charging device, the amount of electric power to be allocated to each electric vehicle must be appropriately distributed.

[제어부의 초기전력분배][Initial power distribution of the control unit]

바람직한 실시예에서 제어부(230)는 컨버터(240)를 통해 충전되는 전기자동차의 개수가 단수에서 N개(단, N은 2 이상의 정수)로 전환될 때, 컨버터(또는 충전장치)의 최대용량을 N분하여 각각의 충전부로 전달한다. 예를 들어 충전장치(200)의 최대충전용량이 50KW이고 충전 중인 전기자동차가 2개인 경우에는, 각각의 전기자동차에 25KW를 분배한다. 이때 무선충전모듈이 사용하는 표준규격이 최대출력을 20KW로 제한하는 경우에는 무선충전모듈을 사용하는 전기자동차에 20KW를 분배하고, 유선충전모듈을 사용하는 전기자동차에 나머지 용량을 분배할 수 있다. In a preferred embodiment, the controller 230 determines the maximum capacity of the converter (or charging device) when converting the number of electric vehicles charged through the converter 240 from N to N (where N is an integer greater than or equal to 2) N minutes to each of the live parts. For example, when the maximum charging capacity of the charging apparatus 200 is 50 KW and there are two electric vehicles being charged, 25 KW is distributed to each electric vehicle. At this time, when the standard used by the wireless charging module limits the maximum output to 20 KW, 20 KW can be distributed to the electric vehicle using the wireless charging module and the remaining capacity can be distributed to the electric vehicle using the wired charging module.

[제어부의 전력재분배][Power Redistribution of Control Section]

제어부(230)는 초기 전력분배 이후에 복수의 충전부를 통해 충전되는 전력량을 모니터링하여, 어느 하나의 충전부를 통해 충전되는 전력량이 감소하면, 다른 하나의 충전부를 통해 충전되는 전력량을 증가시킨다. 예를 들어, 어느 하나의 전기자동차가 완충에 가까워옴에 따라 단위시간당 충전되는 전력량이 초기 전력분배량보다 감소하면, 나머지 전력을 다른 전기자동차에 공급하는 것이다. The controller 230 monitors the amount of power charged through the plurality of charging units after the initial power distribution and increases the amount of power charged through the other charging unit when the amount of power charged through one charging unit decreases. For example, if the amount of electric power to be charged per unit time is lower than the initial electric power distribution amount as one of the electric vehicles approaches the buffer, the remaining electric power is supplied to another electric vehicle.

제어부의 초기전력분배와 그 이후의 전력재분배를 보다 상세하게 설명하기 위해 도 3을 예로 들어 설명한다.The initial power distribution of the control unit and the subsequent power redistribution will be described in more detail with reference to FIG.

도 3은 본 발명의 전기자동차 충전장치에서 복수의 전기자동차를 충전할 때 전력분배하는 방법을 설명하기 위한 그래프이다.3 is a graph for explaining a method of distributing power when charging a plurality of electric vehicles in the electric vehicle charging apparatus of the present invention.

도 3에서 C1은 먼저 충전을 시작한 전기자동차의 단위시간당 충전전력을 나타내는 그래프이다. C2는 소정의 시간 이후에 충전을 시작한 두번째 전기자동차이다.In FIG. 3, C1 is a graph showing the charging power per unit time of the electric vehicle in which charging is first started. C2 is the second electric vehicle that started charging after a predetermined time.

T0구간에서 충전장치는 하나의 전기자동차에 대해서만 충전을 진행중이다. 따라서 제어부는 충전장치의 충전용량을 다른 전기자동차에 분배하지 않아도 된다.In the T0 section, the charging device is charging only one electric vehicle. Therefore, the control unit does not have to distribute the charging capacity of the charging device to another electric vehicle.

1000sec 지점에서 두번째 전기자동차가 충전을 개시한다. T1 구간은 제어부의 초기전력분배를 설명하는 구간이다. 제어부는 각각의 전기자동차에 전력을 분배한다.At the point of 1000sec, the second electric car starts charging. The T1 interval is a period for explaining the initial power distribution of the control unit. The control unit distributes power to each electric vehicle.

3200sec 지점부터 T2 구간이 시작된다. T2 구간에서 제어부는 기 분배된 전력을 재분배한다. C1에서 알 수 있듯이, 첫번째 전기자동차에 충전되는 전력량은 점차 감소된다. 제어부는 감소되는 전력량만큼을 두번째 전기자동차에 재분배한다. C2에서 알 수 있듯이 두번째 전기자동차에 충전되는 전력량이 점차 증가한다.T2 segment starts from 3200 sec. In the T2 interval, the control unit redistributes the distributed power. As can be seen from C1, the amount of power charged in the first electric vehicle is gradually reduced. The control unit redistributes the reduced amount of power to the second electric vehicle. As can be seen from C2, the amount of electric power charged in the second electric vehicle gradually increases.

5000sec 지점부터 T3 구간이 시간된다. T3 구간에서 첫번째 전기자동차는 충전이 완료된다. 그러므로 제어부는 첫번째 전기자동차에 전력을 분배하지 않고 두번째 전기자동차에 모두 투입한다.From the point of 5000 sec, the time interval T3 is time. In the T3 section, the first electric vehicle is charged. Therefore, the control unit does not distribute electric power to the first electric vehicle but inputs it to the second electric vehicle.

도 4는 본 발명의 전기자동차 충전장치로 충전하는 전기자동차를 설명하기 위한 도면이다. 예를 들어 도 1의 1번 전기자동차(11)는 유선충전부(210)에 연결되는 동시에 무선충전부(220)에 연결된다. 1번 전기자동차(11)는 유선충전 또는 무선충전 중에서 보다 신속한 충전이 가능한 충전모듈을 선택하여 충전할 수 있다. 예를 들어 전기자동차의 제어부는 유선충전량과 무선충전량을 비교연산하여 보다 신속하게 충전할 수 있는 충전모듈을 선택하여 충전할 수 있다. 한편, 다른 실시예에서 본 발명의 전기자동차 충전장치(200)는 제어부(230)를 이용하여 유선충전량과 무선충전량을 비교연산하고, 보다 신속하게 전기자동차(11)를 충전할 수 있는 충전모듈을 선택하여 충전할 수 있다.4 is a view for explaining an electric vehicle charged with an electric vehicle charging apparatus of the present invention. For example, the first electric vehicle 11 of FIG. 1 is connected to the wireless charging unit 220 while being connected to the wire charging unit 210. The No. 1 electric vehicle 11 can select and charge the charging module capable of charging more quickly among wired charging or wireless charging. For example, the control unit of the electric vehicle can charge the charging module by selecting a charging module that can charge the battery more quickly by comparing the wired and wireless charging amounts. Meanwhile, in another embodiment, the electric vehicle charging apparatus 200 of the present invention compares a wired charge amount and a wireless charge amount by using the controller 230 and compares the wireless charge amount with a charge module that can charge the electric vehicle 11 more quickly Can be selected and charged.

이를 위해 본 발명의 전기자동차(100)는 도 4에서 알 수 있듯이, 유선충전모듈(110), 무선충전모듈(120), 스위칭부(130), 배터리(140), 제어부(150)를 포함한다. 전기자동차(100)는 외부의 전기자동차 충전장치(200)로부터 유선 또는 무선으로 전기에너지를 공급받아 배터리(140)를 충전한다.4, the electric vehicle 100 includes a wired charging module 110, a wireless charging module 120, a switching unit 130, a battery 140, and a controller 150 . The electric vehicle 100 receives electric energy from an external electric vehicle charging apparatus 200 by wire or wirelessly and charges the battery 140. [

유선충전모듈(110)은 외부 유선충전장치(210)로부터 유선으로 전력을 수신한다. 유선충전모듈(110)은 유선충전케이블(211)을 통해 직접 전기에너지를 공급받으며 그 형식에는 특별한 제한이 없다. 예를 들어, 교류 삼상 380V를 이용하는 급속충전방식이나 교류 단상 220V를 이용하는 완송충전방식을 포함하여 새롭게 정의되는 유선충전표준을 모두 포함할 수 있다. The wired charging module 110 receives electric power from the external wired charging device 210 by wire. The wired charging module 110 is directly supplied with electric energy through the wired charging cable 211, and there is no particular limitation on its type. For example, it can include all of the newly defined wired charging standards, including the rapid charging method using AC three-phase 380V and the full charging method using AC single phase 220V.

무선충전모듈(120)은 외부 무선충전장치(220)로부터 무선으로 전력을 수신한다. 무선충전모듈(120)이 무선으로 전력을 수신하기 위해 사용하는 방식에는 특별한 제한이 없다. 예를 들어, 근거리 무선전송방법으로 자기유도방식과 자기공명방식, 원거리 무선전송방법으로 마이크로파방식 및 레이져방식 등이 본 발명의 무선충전모듈(120)에 적용될 수 있다.The wireless charging module 120 receives power from the external wireless charging device 220 wirelessly. There is no particular limitation on the manner in which the wireless charging module 120 uses wirelessly to receive power. For example, a magnetic induction method, a magnetic resonance method, a far-distance wireless transmission method, a microwave method, a laser method, and the like can be applied to the wireless charging module 120 of the present invention.

스위칭부(130)의 전단은 유선충전모듈(110) 및 무선충전모듈(120)에 연결되고, 후단은 배터리(140)에 연결된다. 스위칭부(130)는 스위칭소자를 이용하여 유선충전모듈(110) 및 무선충전모듈(120)에서 전달되는 전력을 택일적으로 배터리(140)에 전달한다.The front end of the switching unit 130 is connected to the wired charging module 110 and the wireless charging module 120 and the rear end is connected to the battery 140. [ The switching unit 130 may alternatively transmit the electric power transmitted from the wired charging module 110 and the wireless charging module 120 to the battery 140 using a switching device.

배터리(140)는 전기에너지를 축적한다. 예를 들어 배터리(140)는 배터리팩, 배터리를 제어하는 BMS, 냉각부를 포함할 수 있다. 배터리팩은 복수의 배터리셀을 포함하는 배터리 모듈을 포함할 수 있다. 배터리셀은 양극소재, 음극소재, 전해역, 분리막을 이용하여 제작한다. 다만, 본 발명에 사용되는 배터리(140)의 종류와 용량에는 특별한 제한이 없다.The battery 140 accumulates electric energy. For example, the battery 140 may include a battery pack, a BMS for controlling the battery, and a cooling unit. The battery pack may include a battery module including a plurality of battery cells. The battery cell is fabricated using a cathode material, a cathode material, a transfer zone, and a separator. However, the type and capacity of the battery 140 used in the present invention are not particularly limited.

제어부(150)는 유선충전모듈(110)에서 충전되는 전력량을 연산하고, 무선충전모듈(120)에서 충전되는 전력량을 연산한다. 제어부(150)는 연산된 전력량을 비교하여 어떤 충전모듈을 이용했을 때 더욱 신속하게 배터리(140)를 충전할 수 있는지 결정한다. 결정이 완료되면 제어부(150)는 스위칭부(130)를 제어하여 유선충전모듈(110) 또는 무선충전모듈(120) 중 어느 하나가 배터리(140)를 충전하도록 한다.The control unit 150 calculates the amount of power charged in the wired charging module 110 and calculates the amount of power to be charged in the wireless charging module 120. [ The control unit 150 compares the calculated amount of power and determines whether the battery 140 can be charged more quickly when a certain charging module is used. The controller 150 controls the switching unit 130 so that either the wired charging module 110 or the wireless charging module 120 charges the battery 140. [

Also, the wired charging device 210 provides the electric vehicle 100 with a first control signal including characteristic information of the electric energy supplied through the wired charging cable 211. The first control signal may be wired to the wired charging module 110 and the first control signal applied to the wired charging module 110 finally reaches the control unit 150.

무선충전장치(220)는 무선전력전송기술을 이용하여 전기에너지를 공급한다. 예를 들어, 충전장소의 바닥 하부에 교류를 발생시키는 급전선로를 자성재료와 함께 매설하여 전력을 전달한다. 또한, 무선충전장치(220)는 공급하는 전기에너지의 특성 정보를 포함하는 제2제어신호를 전기자동차(100)에게 제공한다. 제2제어신호는 최종적으로 제어부(150)에 도달한다.The wireless charging device 220 supplies electrical energy using a wireless power transmission technique. For example, a feed line for generating an alternating current is buried in the bottom of a filling place together with a magnetic material to transmit electric power. Further, the wireless charging device 220 provides the electric vehicle 100 with a second control signal including characteristic information of electric energy to be supplied. The second control signal finally reaches the control unit 150.
