Description

전기자동차{Electric vehicle}Electric vehicle

본 발명은 전기자동차에 관한 것이다.The present invention relates to an electric vehicle.

경제 발전에 따라 자동차에 대한 수요가 폭발적인 증가세를 보이고 있고, 자동차 수요가 늘어남에 따라 자동차에서 배출되는 배기가스가 환경오염의 주요 원인이 되고 있다. 이에 자동차의 배기가스를 감소시키기 위한 요구가 이어지고 있으며, 배기가스를 줄일 수 있는 자동차의 연구 및 개발이 진행되고 있으며, 더 나아가 배기가스를 발생하지 않는 전기 자동차의 상용화가 부분적으로 시도되고 있다. 전기 자동차는 전기를 전력공급원으로 하여 운행하는 자동차를 의미하며, 자동차 자체에 전력공급원으로 충전이 가능한 배터리를 탑재하고 탑재된 배터리에서 공급되는 전력을 이용하여 운행하는 것을 말한다. 그러나, 이러한 전기자동차는 배터리를 한번 충전하여 주행하는 거리가 제한적이므로, 장거리 운행에 다소 어려움이 따른다.Demand for automobiles has increased explosively due to economic development, and exhaust emissions from automobiles are becoming a major cause of environmental pollution as demand for automobiles increases. Accordingly, a demand for reduction of exhaust gas of automobiles is continuing, research and development of automobiles capable of reducing exhaust gas are being carried out, and further commercialization of electric automobiles that do not generate exhaust gas has been partially attempted. An electric vehicle refers to an automobile that operates by using electricity as a power source, and refers to a vehicle that carries a battery that can be charged as a power source and that is powered by the battery. However, such an electric vehicle has difficulty in long-distance operation because the distance traveled by charging the battery once is limited.

본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있을 정도로 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.
DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

도 1은 본 발명의 일 실시예에 따른 전기자동차를 도시한 개략적인 측면도이다. 도 2는 본 발명의 일 실시예에 따른 전기자동차를 도시한 개략적인 저면도이다. 도 3은 본 발명의 일 실시예에 따른 전기자동차를 도시한 블록도이다. 1 is a schematic side view showing an electric vehicle according to an embodiment of the present invention. 2 is a schematic bottom view illustrating an electric vehicle according to an embodiment of the present invention. 3 is a block diagram illustrating an electric vehicle according to an embodiment of the present invention.

도 1 내지 도 3를 참조하면, 본 발명의 일 실시예에 따른 전기자동차(100)는 차량(200) 및 전력공급장치(300)를 포함한다. 여기서, 상기 차량(200)은 이차전지(223)로 구동하는 자동차이고, 상기 전력공급장치(300)는 상기 차량(200)에 별도로 결합되며 연료전지(314)가 장착되어 상기 차량(200)에 전력을 공급하는 장치이다. 즉, 상기 전력공급장치(300)는 필요에 따라 차량(200)에 결합 및 분리가 가능하다.
Referring to FIGS. 1 to 3, an electric vehicle 100 according to an embodiment of the present invention includes a vehicle 200 and a power supply 300. Here, the vehicle 200 is a vehicle driven by a secondary battery 223, and the power supply 300 is separately connected to the vehicle 200, and a fuel cell 314 is mounted to the vehicle 200 It is a device that supplies power. That is, the power supply 300 can be coupled to and disconnected from the vehicle 200 as needed.

상기 차량(200)은 전실(211), 탑승자실(212), 앞시트 아래영역(213), 뒷시트 아래영역(214) 및 트렁크룸(215)으로 구분될 수 있다. 또한, 상기 차량(200)은 차륜용 좌측모터(221), 차륜용 우측모터(222), 이차 전지(223), VCU(Vehicle Control Unit)(224), 전력분배기(225), 인버터(226), 충전구(227) 및 완속충전기(228)를 포함한다. 더불어, 상기 차량(200)은 프론트 시트(231), 리어 시트(232), 대시패널(233), 차량바닥(234), 앞시트 단차면(235), 뒷시트 단차면(236), 트렁크 칸막이면(237), 기준면(238), 앞차축 사이공간(sf) 및 뒷차축 사이공간(sr)을 더 포함한다. The vehicle 200 may be divided into an entire room 211, a passenger compartment 212, a front seat lower area 213, a rear seat lower area 214, and a trunk room 215. The vehicle 200 includes a left wheel motor 221, a right wheel motor 222, a secondary battery 223, a VCU (Vehicle Control Unit) 224, a power distributor 225, an inverter 226, A filler port 227, and a slow charge charger 228. In addition, the vehicle 200 includes a front seat 231, a rear seat 232, a dash panel 233, a vehicle floor 234, a front seat stepped surface 235, a rear seat stepped surface 236, Plane 237, reference plane 238, space between front axle sf and space between rear axle sr.

상기 차륜용 좌측 모터(221) 및 차륜용 우측 모터(222)는 인휠모터로 양륜을 연결하는 차축이 없다. 따라서, 상기 차량(200)은 전실(211)이 통상적인 차량보다는 짧지만 차축이 없어서, 상기 전실(211)을 효율적으로 사용할 수 있다. 본 발명에서는 상기 앞차축 사이공간(sf)을 탑승자실(212)로 사용한다. 여기서, 일부 조향 부품 및 충격 흡수 구조는 비교적 짧은 전실(211)안에 형성된다. 따라서, 운전자는 프론트 시트(231)에서 대시패널(233)까지 승차하게 된다. The left wheel motor 221 and the right wheel motor 222 do not have axles connecting the two wheels with the in-wheel motor. Therefore, the vehicle 200 is shorter than the conventional vehicle, but has no axle, so that the front chamber 211 can be efficiently used. In the present invention, the space (sf) between the front axles is used as a passenger compartment (212). Here, some of the steering parts and the shock absorbing structure are formed in the relatively short front chamber 211. Therefore, the driver rides from the front seat 231 to the dash panel 233.

상기 앞시트 단차면(235)으로 구분되는 앞시트 아래영역(213)에는 전륜 좌/우측 모터를 한번에 구동하는 인버터(226)와 완속충전기(228)가 장착되어 전실(211)을 구성하는 부품을 줄일 수 있다.

The power supply 300 may be connected to the rear of the vehicle 200 with a pulling ring 311. Further, since the power supply device 300 has no power transmission device, the bomb 315 can be easily installed between the wheels. The power supply 300 is provided with a fuel cell 314 for compressing air in an air compressor 316 and fusing hydrogen in the cylinder 315 to generate electric power. In addition, a radiator 317 for managing the heat generated in the fuel cell 314 is disposed in front of the power supply device 300. The PCU 320 controls the air compressor 316 and the mass flow controller 318 and communicates with the VCU 224 when the vehicle 200 is connected to the vehicle 200.

더불어, 상기 전력공급장치(300)를 상기 차량(200)에 결합할 때는 상기 전력 케이블(312)을 상기 충전구(227)에 연결한다. 상기 전력 케이블(312)은 상기 연료전지(314)의 전력을 차량(200)으로 전달하며, 상기 전력은 전력분배기(225)를 통해 이차전지(223)로 전달된다. 또한, 상기 연료전지(314)의 ON/OFF 및 각종 제어를 위한 신호케이블(313)도 상기 차량(200)에 연결한다. 상기 신호케이블(313)은 VCU(224)와 PCU(320) 사이를 연결한다. In addition, when the power supply 300 is coupled to the vehicle 200, the power cable 312 is connected to the charging port 227. The power cable 312 transfers the power of the fuel cell 314 to the vehicle 200 and the power is transmitted to the secondary battery 223 through the power distributor 225. Also, a signal cable 313 for ON / OFF and various control of the fuel cell 314 is connected to the vehicle 200. The signal cable 313 connects between the VCU 224 and the PCU 320.

상기와 같이, 장거리 운행시는 차량(200)에 전력공급장치(300)를 추가로 연결하여 사용한다. 이때, 상기 VCU(224)는 차량(200)에 장착된 이차전지(223)의 방전량이 기준값 이상이면, 상기 PCU(320)에 명령을 내려 연료전지(314)를 작동시키고 주행과 동시에 이차전지(223)를 충전시킨다. 이와 같이, 상기 연료전지(314)는 간헐적인 on/off없이 지속적으로 운전된다. 또한, 상기 VCU(224)는 이차전지(223)의 충전량이 기준값 이상이면, 상기 PCU(320)에 명령을 내려 연료전지(314)의 작동을 중지시킨다. 상기 차량(200)과 전력공급장치(300)는 신호케이블(313)을 통해서 지속적인 통신을 진행한다. 또한, 상기 VCU(224)는 회생 제동시 급격한 부하 상승을 방지하기 위해 연료전지(314)가 작동하는 상황에서는 인버터(226)의 회생제동브레이크 기능을 정지시킨다. As described above, the power supply device 300 is additionally connected to the vehicle 200 for long-distance operation. If the discharge amount of the secondary battery 223 mounted on the vehicle 200 is equal to or greater than the reference value, the VCU 224 instructs the PCU 320 to operate the fuel cell 314, 223). Thus, the fuel cell 314 is continuously operated without intermittent on / off. The VCU 224 commands the PCU 320 to stop the operation of the fuel cell 314 when the charged amount of the secondary battery 223 is equal to or greater than the reference value. The vehicle 200 and the power supply 300 conduct continuous communication through the signal cable 313. In addition, the VCU 224 stops the regenerative braking function of the inverter 226 in a situation where the fuel cell 314 is operating to prevent a sudden increase in load during regenerative braking.

따라서, 본 발명에 따른 전기자동차(100)는 전력공급장치(300)가 없을 경우 차량(200)의 공차 중량이 감소하여 단거리 주행시 주행거리가 확대되고, 차량(200)에 전력공급장치(300)가 연결된 장거리 주행시는 연료전지(314)의 간헐적인 on/off 작동이 없으므로 기존의 연료전지차에 비해 연료전지(314)의 정밀하고 급작스런 제어가 필요 없어 안정성이 향상된다.
Therefore, in the electric vehicle 100 according to the present invention, when the power supply device 300 is not provided, the tolerance of the vehicle 200 decreases, the traveling distance at the time of short- There is no intermittent on / off operation of the fuel cell 314 at the time of long-distance running, so that precise and sudden control of the fuel cell 314 is unnecessary compared to the existing fuel cell vehicle, and stability is improved.

이상에서 설명한 것은 본 발명에 의한 전기자동차를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.
