그리고, 상기 내측 본체부(11), 외측 본체부(12), 내측 덮개부(21) 및 외측 덮개부(22)는, 상기 케이싱부재(100)의 강도보강을 위하여 각각 탄소나노튜브(Carbon nanotube)(미도시)로 코팅처리되는 것이 바람직하다. 상기 탄소나노튜브는 탄소 6개로 이루어진 육각형들이 서로 연결되어 있는 관 모양을 이루고 있는 소재로서, 상기 케이싱부재(100)의 강도를 크게 하여, 상기 케이싱부재(100)의 내부가 비정상적으로 고온/고압 상태가 되어 상기 배터리 셀(3)이 폭발한다 하더라도 상기 케이싱부재(100)의 파괴로 인한 파편의 비산 등을 최소화시킬 수 있게 한다.The inner body portion 11, the outer body portion 12, the inner cover portion 21, and the outer cover portion 22 are carbon nanotubes, respectively, to reinforce the strength of the casing member 100. It is preferred to be coated with (not shown). The carbon nanotubes are tubular materials in which hexagons made of six carbons are connected to each other. The carbon nanotubes increase the strength of the casing member 100 so that the inside of the casing member 100 is abnormally in a high temperature / high pressure state. Even if the battery cell (3) explodes to minimize the scattering of debris due to the destruction of the casing member (100).

본 실시예에서 상기 온도센서(200)와 가열장치(300)는, 상기 본체프레임(10)의 외측 본체부(12)에 설치되도록 구성되나, 본 발명은 반드시 이에 한정되지 않고 예컨대 상기 본체프레임(10)의 내측 본체부(11) 또는 덮개프레임(20) 측에 설치되도록 구성되는 것도 가능하다. In this embodiment, the temperature sensor 200 and the heating device 300 is configured to be installed on the outer body portion 12 of the body frame 10, the present invention is not necessarily limited to this, for example the body frame ( It is also possible to be configured to be installed on the inner body portion 11 or the cover frame 20 side of 10).

상기 온도센서(200)는 상기 케이싱부재(100)의 유로(60)의 온도를 감지하기 위한 것으로, 전기자동차가 예컨대 영하 20℃ 이하인 주행환경에서 주행되는 경우에 상기 가열장치(300)와 함께 상기 케이싱부재(100)의 내부의 온도의 하락으로 상기 배터리 셀들이 비정상적으로 작동하는 것을 방지하는 역할을 한다.The temperature sensor 200 is for sensing the temperature of the flow path 60 of the casing member 100, together with the heating device 300 when the electric vehicle is traveling in a driving environment of, for example, minus 20 ℃ or less. The temperature of the inside of the casing member 100 is lowered to prevent the battery cells from operating abnormally.

즉, 도 4에 잘 도시된 바와 같이, 상기 온도센서(200)가 상기 케이싱부재(100)의 유체의 온도를 감지하여 그 케이싱부재(100)의 내부온도를 감지하게 되고, 감지된 온도가 기준치(예컨대 0℃) 이하인 경우에는 상기 가열장치(300)가 상기 유체의 온도가 기준치에 도달할 때가지 그 유체를 히팅시킨다. 한편, 상기 가열장치(300)의 가열로 유체의 온도가 기준치에 부합하는 경우에는 상기 가열장치(300)에 의한 히팅을 중단시킨다.That is, as shown in Figure 4, the temperature sensor 200 detects the temperature of the fluid of the casing member 100 to detect the internal temperature of the casing member 100, the detected temperature is a reference value (Eg, 0 ° C.) or less, the heating device 300 heats the fluid until the temperature of the fluid reaches a reference value. On the other hand, when the temperature of the fluid by heating the heating device 300 meets the reference value, the heating by the heating device 300 is stopped.

상술한 바와 같이, 본 발명에 의한 전기자동차의 배터리 하우징은, 상기 케이싱부재(100)의 단열 및 냉각성능을 우수하게 할 뿐만 아니라, 전기자동차가 예컨대 영하 20℃ 이하인 주행환경에서 주행되는 경우에 상기 케이싱부재(100)를 직접 히팅시키지 않고 그 케이싱부재(100)의 유로(60) 상에 유동하는 유체를 간접 히팅시킴으로써 극저온 주행환경으로 인한 배터리 셀(3)의 오작동을 방지할 수 있고 안전에 위협을 가하는 직접가열로 인한 문제를 간접가열 방식으로 해결할 수 있는 장점을 가진다. As described above, the battery housing of the electric vehicle according to the present invention not only improves the insulation and cooling performance of the casing member 100, but also when the electric vehicle is driven in a driving environment of, for example, 20 degrees Celsius or less. By indirectly heating the fluid flowing on the flow path 60 of the casing member 100 without directly heating the casing member 100, it is possible to prevent malfunction of the battery cell 3 due to the cryogenic running environment and to threaten safety. Indirect heating has the advantage of solving the problems caused by direct heating.

한편, 도 3에 잘 도시된 바와 같이, 상기 배터리 셀들은 적층프레임(F)에 적층된 상태로 상기 케이싱부재의 내측에 배치된다. 본 실시예에서 상기 각 배터리 셀(3)은 양극부(31)와 음극부(32)와 절연부(33)를 구비한다. 상기 양극부(31)에는 양극단자(311)가 돌출되어 있고 상기 음극부(32)에는 음극단자(321)가 돌출되어 있으며 상기 절연부(33)는 상기 양극부(31)와 음극부(32)를 절연시키기 위한 것으로 상기 양극부(31)와 음극부(32) 사이에 단차지게 형성되어 있다. Meanwhile, as shown in FIG. 3, the battery cells are disposed inside the casing member in a state in which the battery cells are stacked in the stacking frame (F). In the present embodiment, each of the battery cells 3 includes a positive electrode part 31, a negative electrode part 32, and an insulating part 33. A positive electrode terminal 311 protrudes from the positive electrode portion 31, a negative electrode terminal 321 protrudes from the negative electrode portion 32, and the insulating portion 33 includes the positive electrode portion 31 and the negative electrode portion 32. ) Is formed to step between the anode portion 31 and the cathode portion 32.

이와 같이 상기 절연부(33)가 단차지게 형성되어 있고 상기 양극단자(311) 및 음극단자(321)의 돌출로 인하여, 각 배터리 셀(3)의 적층이 용이하게 수행될 수 있는 것이다. 즉, 하측에 위치되어 있는 배터리 셀(3)에, 상측에 위치될 인접한 배터리 셀(3)을 상측에서 하측으로 향한 방향으로 안착시키기만 하면, 하측에 위치된 배터리 셀(3)의 양극단자(311)에 상측에 위치된 배터리 셀(3)의 양극부(31)가 전기적으로 연결되고 마찬가지로 하측에 위치된 배터리 셀(3)의 음극단자(321)와 상측에 위치된 배터리 셀(3)의 음극부(32)가 전기적으로 연결됨으로써 각 배터리 셀(3)의 극성연결작업을 추가적으로 수행할 필요가 없게 된다. As described above, the insulating part 33 is formed to be stepped, and due to the protrusion of the positive electrode terminal 311 and the negative electrode terminal 321, the stacking of each battery cell 3 can be easily performed. That is, the positive electrode terminal of the battery cell 3 located on the lower side may be provided by simply seating the adjacent battery cell 3 to be positioned on the lower side in the direction from the upper side to the lower side. The positive electrode 31 of the battery cell 3 positioned on the upper side of the battery cell 3 is electrically connected to the 311 and similarly connected to the negative terminal 321 of the battery cell 3 positioned on the lower side and the battery cell 3 positioned on the upper side thereof. Since the negative electrode part 32 is electrically connected, there is no need to additionally perform the polarity connection of each battery cell 3.
