전기자동차는 전기를 동력으로 하여 움직이는 자동차이다. 전기자동차는 자동차의 구동에너지를 기존의 자동차와 같이 화석 연료의 연소로부터가 아닌 전기에너지로부터 얻는 자동차이다. 자동차에서의 배기가스가 전혀 없으며, 소음이 아주 작은 장점이 있다. 그러나 배터리의 무거운 중량, 충전에 걸리는 시간 등의 문제 때문과 충전시설을 구축해야 하다는데 많은 비용과 장소적 제한 때문에 문제점이 있다. 배터리의 경량, 소형화 및 짧은 충전시간은 전기자동차가 실용화되기 위한 필수적인 선결 조건으로 작용한다.An electric vehicle is a vehicle that is driven by electricity. An electric vehicle is a vehicle that obtains driving energy of an automobile from electric energy, not from combustion of fossil fuel, as in a conventional vehicle. There is no exhaust in the car, and the noise is very small. However, there are problems due to the heavy weight of the battery, the time required for charging, and the need for building a charging facility due to the high cost and location limitations. The light weight, small size and short charging time of the battery serve as an essential prerequisite for the practical use of electric vehicles.

이와 같이 이루어진 본 발명의 전기자동차의 배터리 충전장치에 관한 작동을 설명한다.The operation of the battery charging device of the electric vehicle of the present invention made as described above will be described.

완충된 배터리2(10)로부터 제1전원공급라인(L1)을 통해 인버터(18)로 전원이 공급되어 직류전원을 교류전원으로 전환시켜 교류모터(12)로 전원이 공급된다. 이때, 교류모터(12)로 인가되는 전원을 공급되도록 하면서 교류모터(12)가 회전한다. 배터리2(10)에서 공급되는 전원은 교류 330V정도이고, 교류모터(12)는 대략 3.7KW 용량이다. 교류모터(12)는 인가된 전원으로 대략 3,600RPM로 회전된다. 교류모터(12)의 회전력은 회전축(13)을 통해 동력전달부재(11)로 전달되고, 동력전달부재(11)는 3상 교류발전기(14)의 회전축(15)에 동력이 전달되도록 한다. 3상 교류발전기(14)는 동력전달부재(11)를 거쳐 전달된 회전력으로 대략 10KW의 전기에너지를 발생시킨다.Power is supplied from the fully charged battery 2 (10) to the inverter 18 through the first power supply line (L1) to convert the DC power into AC power to supply AC power to the AC motor 12. At this time, the AC motor 12 rotates while supplying power applied to the AC motor 12. The power supplied from the battery 2 (10) is about 330V AC, the AC motor 12 is approximately 3.7KW capacity. The AC motor 12 is rotated at approximately 3,600 RPM with an applied power source. The rotational force of the AC motor 12 is transmitted to the power transmission member 11 through the rotation shaft 13, the power transmission member 11 to transmit power to the rotation shaft 15 of the three-phase alternator (14). The three-phase alternator 14 generates approximately 10 KW of electrical energy with the rotational force transmitted through the power transmission member 11.

3상 교류발전기(14)에서 발생된 전기에너지는 제2전원공급라인을 따라 충전기(16)로 인가되고, 충전기(16)는 인가된 전원, 즉 교류3상 380V를 리튬이온플리머 배터리에 적합한 직류 330V전류로 변환시킨 후에 제4전원공급라인(L4)을 거쳐 배터리1(9)로 공급하여 충전되도록 한다. 따라서 배터리2(10)의 전원이 70％정도 소모가 되면 인버터를 통해 전원을 차단하고 완전 충전되어 있는 배터리1(9)의 전원을 연결시켜 제5전원공급라인(L5)을 통해 전원을 공급하여 인버터(18)에 공급하고 인버터는 직류전원을 교류전원으로 전환하여 교류모터(12)에 공급 모터를 구동하고 전달된 회전력으로 일정 크기의 교류전압을 발생하는 것이다. 더욱이 교류모터(12)의 회전축(13)과 3상 교류발전기(14)의 회전축(15) 사이에 동력전달부재(11), 예를 들어, 고무재질의 V벨트가 체결되어 교류모터(12)의 회전력이 동력전달부재(11)를 거쳐 3상 교류발전기(14)로 전달되어 3상 교류발전기(14)가 전력을 생산하도록 한다. 상기 교류모터(12)의 회전축(13)과 3상 교류발전기(14)의 회전축(15)에는 각각 벨트풀리가 결합되어 동력전달부재(11)를 걸 수 있도록 하는 것이 좋다.The electric energy generated by the three-phase alternator 14 is applied to the charger 16 along the second power supply line, and the charger 16 applies the applied power, that is, an alternating three-phase 380V to a lithium ion polymer battery. After the conversion to DC 330V current through the fourth power supply line (L4) is supplied to the battery 1 (9) to be charged. Therefore, when the power of the battery 2 (10) is consumed about 70%, the power is cut off through the inverter and connected to the fully charged battery 1 (9) to supply power through the fifth power supply line (L5) Supplying to the inverter 18, the inverter converts the DC power into AC power to drive the supply motor to the AC motor 12 and to generate an alternating voltage of a predetermined magnitude with the transmitted rotational force. Furthermore, the power transmission member 11, for example, a rubber V-belt is fastened between the rotation shaft 13 of the AC motor 12 and the rotation shaft 15 of the three-phase AC generator 14 to exchange the AC motor 12. The rotational force of is transmitted to the three-phase alternator 14 through the power transmission member 11 so that the three-phase alternator 14 produces power. A belt pulley may be coupled to the rotary shaft 13 of the AC motor 12 and the rotary shaft 15 of the three-phase AC generator 14 so that the power transmission member 11 can be engaged.

또한,3상 교류발전기(14)는 회전에 따른 발열온도가 상승하여 효율이 저하되거나 망실되지 않도록 냉각장치(20)로부터 각각 제1냉각파이프(P1)와 통해 냉각수가 순환되도록 함으로써 열 교환에 따른 냉각이 이루어지도록 한다.In addition, the three-phase alternator 14 is a heat exchange temperature by rotating the cooling water through the first cooling pipe (P1) from the cooling device 20 so that the efficiency is not lowered or lost due to the increase in the heating temperature according to the heat exchange Allow for cooling.

이와 같이 이루어진 본 발명의 전기자동차의 배터리 충전장치는 전기자동차의 운행 중에도 배터리의 충전이 가능하도록 함으로써 전기자동차의 이용에 편의를 향상시킨 장점이 있다.The battery charging device of the electric vehicle of the present invention made as described above has an advantage of improving convenience in using the electric vehicle by enabling the charging of the battery even while the electric vehicle is in operation.
