Description

수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템Electric vehicle charging system equipped with a mobile charger using hydrogen fuel cells
본 발명은 전기차량을 충전하는 전기차 충전시스템에 대한 것으로서, 상세하게는 이동식 충전기로 전기차를 충전하는 전기차 충전시스템에 대한 것이다.The present invention relates to an electric vehicle charging system for charging an electric vehicle, and more specifically, to an electric vehicle charging system for charging an electric vehicle with a mobile charger.
최근, 자동차 업계에서는 가솔린, 경유 등의 화석 연료 대신 전기를 이용하는 전기차(Electric Vehicle; EV)에 대해 관심이 늘어나고 있으며, 소비자 판매도 증가하고 있다. 전기차는 휘발유, 경유와 같은 화석연료가 아니라 전기 에너지로 구동되기 때문에 기존의 가솔린이나 경유를 사용하는 차량에 비하여 배기가스가 없어 친환경적이며, 또한 소음 발생이 적다는 장점이 있다.Recently, in the automobile industry, interest in electric vehicles (EVs) that use electricity instead of fossil fuels such as gasoline and diesel fuel is increasing, and consumer sales are also increasing. Because electric vehicles are driven by electrical energy rather than fossil fuels such as gasoline or diesel, they are environmentally friendly because they produce no exhaust gases compared to vehicles using existing gasoline or diesel, and also have the advantage of generating less noise.
친환경 자동차의 대세로 자리 잡은 전기차는 짧은 기간 상당한 성장세를 보이고 있지만, 각국 정부의 의욕적인 지원과 정책에도 불구하고 시장의 반응은 그 기대에 미치지 못하는 실정이다. 전기차가 일반 내연자동차를 완전히 대체하지 못하는 가장 큰 걸림돌은 무엇보다도 충분하지 못한 충전 인프라와 충전에 소요되는 시간이라고 할 수 있다. Electric vehicles, which have become a mainstream eco-friendly vehicle, are showing significant growth in a short period of time, but despite ambitious support and policies from governments around the world, the market's response does not meet expectations. The biggest obstacle preventing electric vehicles from completely replacing regular internal combustion vehicles is the insufficient charging infrastructure and the time required for charging.
이러한 전기차의 충전을 위해서는 일반적으로 주유소의 주유기와 같은 충전소의 충전 스탠드를 이용하고 있으며, 현재 구축되고 있는 대부분의 전기자동차 충전시설은 주차공간의 일정 영역에 고정식 충전스탠드를 설치하고 해당 주차구역을 전기자동차 구역으로 설정하는 방식으로 되어 있다.To charge these electric vehicles, a charging stand at a charging station, such as a gas pump at a gas station, is generally used. Most electric vehicle charging facilities currently being built install a fixed charging stand in a certain area of the parking space and use the parking area as an electric vehicle. It is set up as a car zone.
그러나, 현재 전세계적으로 전기차 충전인프라의 주류로 자리잡고 있는 고정식 충전스탠드는 주차공간의 일정 부분을 전기자동차 전용으로 사용하게 되어 전기차 전용 주차구역 지정에 따른 주차분쟁을 야기하고, 또한 투자비 대비 이용률이 매우 낮아 수익성이나 경제성을 충족시키지 못하는 문제가 있다.However, fixed charging stands, which are currently becoming the mainstream of electric vehicle charging infrastructure around the world, require a certain portion of the parking space to be used exclusively for electric vehicles, causing parking disputes due to designation of parking areas exclusively for electric vehicles, and also lowering the utilization rate compared to the investment cost. It is very low, so there is a problem of not meeting profitability or economic feasibility.
한편, 2010년을 전후한 1세대 전기자동차 I-MiEV의 경우 자동차에 탑재된 배터리 용량이 불과 16 [kWh]에 불과했으며, 비슷한 시기의 전기차 리프(Leaf)도 24[kWh]용량의 배터리가 내장되어 있었다. 하지만 최근 주류를 이루는 전기차에 내장되는 배터리의 용량은 80 [kWh] 내외로, 이전 대비 3~4배 이상의 고용량으로 크게 늘어나는 추세에 있으며, 전기차에 탑재되는 배터리 용량이 증대됨에 따라서 급속 충전을 위한 전기차 충전기의 출력도 높은 전력이 요구되어 최근의 급속 충전스탠드는 그 출력이 50 [kW]를 넘어 100 [kW], 350 [kW], 심지어 400 [kW]를 초과하는 초급속 충전까지 등장하고 있다.Meanwhile, in the case of the first generation electric vehicle I-MiEV around 2010, the battery capacity mounted on the car was only 16 [kWh], and the electric vehicle Leaf of a similar time also had a battery with a capacity of 24 [kWh]. It was done. However, recently, the capacity of the batteries built into mainstream electric vehicles is around 80 [kWh], and there is a trend of greatly increasing the capacity to 3 to 4 times higher than before. As the capacity of batteries mounted on electric vehicles increases, the capacity of electric vehicles for rapid charging is increasing. The output of the charger also requires high power, and recent fast charging stands have emerged with output exceeding 50 [kW], and ultra-fast charging with output exceeding 100 [kW], 350 [kW], and even 400 [kW].
이러한 급속 또는 초급속 충전스탠드 등의 고출력 충전설비들이 도심에 고밀도로 설치되면 그 수요 전력을 공급해야 하는 전력계통의 공급 능력에 기술적 한계가 발생하고, 이는 현실적으로 극복하기 어려운 심각한 문제가 될 것이다. If high-output charging facilities such as fast or ultra-fast charging stands are installed at high density in urban areas, technical limitations will arise in the power system's ability to supply the required power, and this will become a serious problem that is difficult to overcome in reality.
특히, 우리나라와 같이 국토가 좁고 도심 과밀형인 사회구조에서는 전기차의 보급과 점유율이 일정 수준을 초과하게 되는 경우, 더 이상 이와 같은 방식의 전기차 충전인프라로는 충분한 전기차 충전환경을 구축할 수 없는 포화 상태를 맞이하게 될 가능성이 크다.In particular, in a social structure like Korea, where the country is small and the city center is overcrowded, when the supply and market share of electric vehicles exceeds a certain level, it is no longer possible to build a sufficient electric vehicle charging environment with this type of electric vehicle charging infrastructure. There is a high possibility that you will encounter
이와 같은 종래의 고정식 충전스탠드에 내재된 문제점을 해결하기 위해 자율주행 충전로봇을 이용한 이동식 충전시스템이 연구되고 있지만, 이런 이동식 충전시스템은 전력계통(Grid)에서 충전된 배터리를 이용하여 전기차를 충전하므로, 충전인프라의 증가로 발생하는 충전수요 전력의 급증 문제는 여전히 해결하지 못하고 있다. 뿐만 아니라, 현재 개발되고 있는 대부분의 자율주행 충전로봇은 급속 충전을 지원하지 못하고 있어, 점차 대용량화 되고 있는 전기차의 배터리 용량을 감안할 때 전기차 충전인프라로서의 기능과 역할을 충분히 담당하기 어려운 문제점이 있다.To solve the problems inherent in conventional fixed charging stands, mobile charging systems using autonomous charging robots are being researched. However, these mobile charging systems charge electric vehicles using batteries charged from the power grid. , the problem of rapid increase in charging power demand caused by the increase in charging infrastructure is still not resolved. In addition, most self-driving charging robots currently being developed do not support fast charging, making it difficult to fully function and serve as an electric vehicle charging infrastructure considering the increasingly large battery capacity of electric vehicles.
따라서, 앞으로 점증할 전기차 충전인프라의 부족 문제를 효과적으로 해결할 방안이 요구되고 있다.Therefore, there is a need for a method to effectively solve the problem of the shortage of electric vehicle charging infrastructure, which will increase in the future.
본 발명의 목적은 고정식 충전스탠드와 같이 주차공간의 일부분을 전기차 전용으로 제한하지 않아도 되어 주차 구역내 주차공간의 점유를 최소화 할 수 있는 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 제공하는 것이다.The purpose of the present invention is to provide an electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell that can minimize the occupancy of parking space in the parking area by not limiting a portion of the parking space to electric vehicles only, such as a fixed charging stand. will be.
본 발명의 다른 목적은 독립전원인 수소연료전지에서 생성된 전력으로 전기차를 충전하므로 전기차 충전인프라의 증가 시에도 전력계통의 전력 수요를 증가시키지 않으면서도 충전수요 전력의 급증 문제를 해결할 수 있는 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 제공하는 것이다.Another object of the present invention is to charge electric vehicles with power generated from hydrogen fuel cells, which are independent power sources, so as to provide hydrogen fuel that can solve the problem of a surge in charging power without increasing power demand in the power system even when electric vehicle charging infrastructure increases. The aim is to provide an electric vehicle charging system equipped with a portable charger using batteries.
본 발명의 또다른 목적은 상황에 따라 유연성 있게 이동식 충전기만 추가할 수 있어 기존의 충전스탠드 대비 저렴한 비용으로 늘어나는 충전인프라 수요를 수용할 수 있는 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 제공하는 것이다.Another object of the present invention is to provide an electric vehicle charging system equipped with a mobile charger using hydrogen fuel cells that can accommodate the increasing demand for charging infrastructure at a lower cost than existing charging stands by allowing only mobile chargers to be added flexibly depending on the situation. It is provided.

Figure 2(a) shows the overall configuration of the mobile charger, and Figure 2(b) shows the power generation unit in the mobile charger. It shows the structure.
도 1 및 도 2 를 참조하면, 본 발명의 일 실시예에 따른 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은, 수소 저장탱크를 구비하고 전기차를 충전하고 돌아온 이동식 충전기(200)의 수소 연료를 보충해 주는 수소 충전타워(100), 및 상기 수소 충전타워(100)에서 충전된 수소 연료를 토대로 전력을 생성하고 전기차가 주차된 구역으로 이동하여 충전을 수행하는 이동식 충전기(200)로 이루어진다.Referring to Figures 1 and 2, an electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell according to an embodiment of the present invention is equipped with a hydrogen storage tank and charges the electric vehicle and returns the hydrogen from the mobile charger 200. It consists of a hydrogen charging tower 100 that replenishes fuel, and a mobile charger 200 that generates power based on the hydrogen fuel charged in the hydrogen charging tower 100 and moves to the area where the electric vehicle is parked to perform charging. .
여기서, 수소 충전타워(100)는 지하 또는 지상에 대용량의 수소연료 저장탱크를 구비하고, 전기차를 충전하고 돌아온 이동식 충전기(200)의 수소 연료를 보충해 준다. 구현예에 따라서는, 상기 수소 충전타워(100)에 자동연료보충장치를 구비하여 이동식 충전기(200)의 수소탱크(2211)를 자동으로 보충하도록 할 수 있다.Here, the hydrogen charging tower 100 is equipped with a large-capacity hydrogen fuel storage tank underground or above ground, and replenishes the hydrogen fuel of the mobile charger 200 returning from charging the electric vehicle. Depending on the implementation, the hydrogen charging tower 100 may be equipped with an automatic fuel replenishment device to automatically replenish the hydrogen tank 2211 of the mobile charger 200.
한편, 이동식 충전기(200)는 바퀴와 같은 이동가능하게 하는 이동부(210)와, 수소연료를 토대로 전력을 생성하여 전기차 충전을 수행하는 충전장치부(220)로 구분될 수 있다.Meanwhile, the mobile charger 200 can be divided into a moving part 210 that allows movement, such as wheels, and a charging device part 220 that generates power based on hydrogen fuel to charge the electric vehicle.
여기서, 충전장치부(220)는 수소탱크(2210)에 저장된 수소를 토대로 전력을 생성하는 전력생성부(221), 사용자에 의해 전기차에 플러그인(plug-in) 되어 전기차 충전을 수행하는 충전플러그(222), 및 전기차 충전이 완료되면 상기 충전플러그(222)를 회수하는 충전플러그 회수부(225)로 이루어져 있다.Here, the charging device unit 220 includes a power generation unit 221 that generates power based on hydrogen stored in the hydrogen tank 2210, and a charging plug that is plugged in to the electric vehicle by the user and performs electric vehicle charging ( 222), and a charging plug recovery unit 225 that recovers the charging plug 222 when charging of the electric vehicle is completed.
또한, 전력생성부(221)는 수소 연료를 보관하는 수소탱크(210), 수소탱크(221)에 저장된 수소를 토대로 전력을 생성하는 수소연료전지(222), 및 생성된 전력을 전기차 충전에 적합하게 변환하는 전력변환부(223)를 구비할 수 있다.In addition, the power generation unit 221 includes a hydrogen tank 210 that stores hydrogen fuel, a hydrogen fuel cell 222 that generates power based on the hydrogen stored in the hydrogen tank 221, and the generated power is suitable for charging an electric vehicle. It may be provided with a power conversion unit 223 that converts the power.
즉, 본 발명에서는 사용자에 의해 충전플러그(222)가 전기차의 충전구에 삽입 및 결합되어 고속 충전이 이루어지게 되고, 이후 충전이 완료되면 본 발명의 충전플러그 회수부(223)에 의해 충전 플러그(222)가 전기차 충전구로부터 언플러깅(unplugging) 되게 된다. That is, in the present invention, the charging plug 222 is inserted and coupled to the charging port of the electric vehicle by the user to achieve high-speed charging. After charging is completed, the charging plug recovery unit 223 of the present invention uses the charging plug ( 222) is unplugged from the electric vehicle charging port.
그리고, 충전플러그(222)가 충전플러그 회수부(223)에 의해 전기차로부터 언플러깅 된 후에는 본 발명의 이동식 충전기(200)는 수소 충전타워(100)로 복귀하게 되고, 수소 충전타워(100)에서 이동식 충전기(200)의 수소탱크(2211)의 수소 연료를 보충해 줌으로써 계속적인 전기차 충전 작업이 이루어질 수 있도록 한다.And, after the charging plug 222 is unplugged from the electric vehicle by the charging plug recovery unit 223, the mobile charger 200 of the present invention returns to the hydrogen charging tower 100, and the hydrogen charging tower 100 By replenishing hydrogen fuel in the hydrogen tank 2211 of the mobile charger 200, continuous charging of the electric vehicle can be performed.
이를 위해, 구현예에 따라서는 본 발명의 이동식 충전기(200)에 자율주행 기능을 추가하여, 충전플러그(222)가 전기차로부터 언플러깅 된 후 자동으로 수소 충전타워(100)로 복귀하도록 할 수도 있다. To this end, depending on the implementation, an autonomous driving function may be added to the mobile charger 200 of the present invention so that the charging plug 222 automatically returns to the hydrogen charging tower 100 after being unplugged from the electric vehicle. .
한편, 수소연료전지(2212)는 현재의 수소연료전지 상용화 기술의 수준을 고려하였을 때 작은 크기의 파워트레인에서도 300 [kW] 이상의 고출력을 생산할 수 있으며, 이를 통해 배터리를 사용한 이동식 충전기에서는 서비스하기 어려운 급속 또는 초급속의 충전서비스가 가능하다.On the other hand, considering the current level of hydrogen fuel cell commercialization technology, the hydrogen fuel cell (2212) can produce high output of more than 300 [kW] even in a small-sized powertrain, which makes it difficult to service in a mobile charger using a battery. Rapid or ultra-fast charging service is available.
또한, 배터리를 사용한 이동식 충전기에서는 배터리의 크기와 중량은 물론 그 가격과 전기적 특성 등으로 충분한 양의 전력 충전에 한계가 있으나, 본 발명에서 이용하는 수소연료전지의 경우 적정 용량의 수소탱크만으로 충분한 전력량을 공급할 수 있는 장점이 있다.In addition, in portable chargers using batteries, there are limitations in charging a sufficient amount of power due to the size and weight of the battery as well as its price and electrical characteristics. However, in the case of the hydrogen fuel cell used in the present invention, a sufficient amount of power can be supplied only with a hydrogen tank of appropriate capacity. There are advantages to providing it.
이상과 같은 구성으로 이루어진 본 발명의 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은, 충전스탠드마다 AC/DC 인버터와 충전모듈이 필요한 기존의 충전스탠드와 대비해 저렴한 비용으로 증가하는 충전인프라 수요를 수용할 수 있어 경제성이 우수하다.The electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell of the present invention, configured as described above, meets the increasing demand for charging infrastructure at a low cost compared to existing charging stands that require AC/DC inverters and charging modules for each charging stand. It has excellent economic efficiency as it can accommodate .
또한, 본 발명의 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은 전기차 충전시스템이 설치된 사이트의 충전상황에 따라 이동식 충전기만 추가하는 등과 같은 상황에 따른 유연성 있는 대응이 가능하다. In addition, the electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell of the present invention can respond flexibly to situations, such as adding only a mobile charger depending on the charging situation at the site where the electric vehicle charging system is installed.
예를 들어, 1일 총 충전량은 적으나 동시 충전 차량 대수가 많은 경우, 이동부와 충전장치부로만 구성되어 매우 저렴한 이동식 충전기만 추가할 수 있으며, 또한 동시 충전 차량 대수는 많지 않으나 1일 총 충전량이 많은 경우에는 수소 저장탱크를 추가하는 방식으로 수요에 대응할 수 있다.For example, if the total daily charging amount is small but the number of simultaneously charging vehicles is large, only a very inexpensive mobile charger consisting of only the moving part and the charging device part can be added. Also, although the number of simultaneously charging vehicles is not large, the total daily charging amount can be added. In many of these cases, demand can be responded to by adding hydrogen storage tanks.
다음, 본 발명에 의한 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 사용하여 전기차를 충전하는 경우에 대해 도 3을 참조하여 설명한다. Next, the case of charging an electric vehicle using an electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell according to the present invention will be described with reference to FIG. 3.
도 3은 본 발명의 일 실시예에 따른 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 이용해 전기차를 충전하는 상황을 나타낸 도면이다. 여기서, “e” 표기가 되어 있는 차량이 전기차 이며, 이러한 표기가 없는 차량은 일반 내연기관 차량을 의미한다. Figure 3 is a diagram showing a situation in which an electric vehicle is charged using an electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell according to an embodiment of the present invention. Here, vehicles marked with an “e” are electric vehicles, and vehicles without this symbol represent general internal combustion engine vehicles.
도 3에서 알 수 있는 바와 같이, 본 발명의 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템을 사용하면, 기존의 고정식 충전스탠드와 같이 전기차 충전을 위한 전기차 주차구역을 지정할 필요가 없고 일반 내연기관 차량과 주차공간을 공유할 수 있다.As can be seen in Figure 3, when using an electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell of the present invention, there is no need to designate an electric vehicle parking area for charging an electric vehicle like a conventional fixed charging stand, and there is no need for a general internal combustion engine charging stand. Parking spaces can be shared with institutional vehicles.
또한, 본 발명의 이동식 충전기(200)는 전기차 충전을 완료한 후 수소 충전타워(100)로 복귀하게 되므로, 전기차에 대한 충전 수행 중에만 이동식 충전기(200)가 사용되어 기존의 충전스탠드와 같은 충전인프라의 낭비가 없다.In addition, since the mobile charger 200 of the present invention returns to the hydrogen charging tower 100 after completing charging the electric vehicle, the mobile charger 200 is used only while charging the electric vehicle, allowing charging like a conventional charging stand. There is no waste of infrastructure.
또한, 본 발명의 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은 전기차가 완충된 상태로 주차되어 충전스탠드를 더 이상 사용하지 못하는 상황이나, 또는 주차구역이 비어있는 운휴 상태로 운영되는 비효율을 최소화할 수 있는 우수한 효율성을 갖고 있다. In addition, the electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell of the present invention is inefficient when the electric vehicle is parked in a fully charged state and the charging stand can no longer be used, or when the parking area is empty and operated in an idle state. It has excellent efficiency to minimize.
이상과 같이 본 발명에 따른 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은, 주차공간의 일부분을 전기차 전용으로 제한하지 않아도 되기 때문에 주차 구역내 주차공간의 점유를 최소화 할 수 있으며, 상황에 따라 유연성 있게 이동식 충전기만 추가할 수 있어 기존의 충전스탠드 대비 저렴한 비용으로 늘어나는 충전인프라 수요를 수용할 수 있다. 또한, 독립전원인 수소연료전지에서 생성된 전력으로 전기차를 충전하므로 전기차 충전인프라의 증가 시에도 전력계통의 전력 수요를 증가시키지 않으면서도 충전수요 전력의 급증 문제를 해결할 수 있다. As described above, the electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell according to the present invention can minimize the occupancy of parking space in the parking area because there is no need to limit a portion of the parking space to exclusive use for electric vehicles, and can minimize the occupancy of parking space in the parking area, depending on the situation. Accordingly, only mobile chargers can be added flexibly, allowing the growing demand for charging infrastructure to be accommodated at a lower cost than existing charging stands. In addition, since electric vehicles are charged with power generated from hydrogen fuel cells, which are independent power sources, the problem of a surge in charging demand can be solved without increasing power demand in the power system even when electric vehicle charging infrastructure increases.
특히, 본 발명에 따른 수소연료전지를 이용한 이동식 충전기를 구비한 전기차 충전시스템은 수소전기차의 보급한계, 수소공급망 구축의 어려움 등 정부의 수소에너지 관련 정책의 많은 문제점과 장애들을 해소할 수 있어, 수소경제의 활성화 및 전기차 보급 촉진을 동시에 실현할 수 있다.In particular, the electric vehicle charging system equipped with a mobile charger using a hydrogen fuel cell according to the present invention can solve many problems and obstacles in the government's hydrogen energy-related policies, such as limitations in the distribution of hydrogen electric vehicles and difficulties in establishing a hydrogen supply network, thereby enabling hydrogen Revitalizing the economy and promoting the spread of electric vehicles can be realized at the same time.
