전기자동차 화재시 배터리를 안정화시키기 위한 냉각조 및 이를 이용한 전기자동차의 배터리 안정화방법{COOLING TANK TO STABILIZE THE BATTERY OF AN ELECTRIC VEHICLE IN WHICH A FIRE OCCURRED}Cooling tank for stabilizing battery in case of electric vehicle fire and method for stabilizing battery of electric vehicle using the same

본 발명은 전기자동차에서 화재발생시 후처리를 하기 위한 것으로서, 특히 전기자동차 화재시 배터리를 안정화시키기 위한 냉각조에 관한 것이다. The present invention relates to a cooling tank for stabilizing a battery in case of a fire in an electric vehicle for post-treatment in case of a fire in an electric vehicle, and more particularly, to a cooling tank for stabilizing a battery in case of a fire in an electric vehicle.

일반적으로 자동차는 가솔린이나 디젤 연료를 사용하는 내연기관을 사용하였으나, 내연기관에서 발산하는 이산화탄소의 문제로 인하여 최근에는 친환경에너지 자동차인 전기자동차의 보급이 증가하고 있다. 이러한 추세는 지구온난화 문제로 전세계적으로 내연기관자동차의 퇴출 분위기는 점점 더 커질 것이고, 이에 반하여 전기자동차의 보급을 매년 꾸준히 증가하고 있고 앞으로 그 점유율을 더욱 올라갈 것이다. In general, automobiles use an internal combustion engine using gasoline or diesel fuel, but due to the problem of carbon dioxide emitted from the internal combustion engine, the supply of electric vehicles, which are eco-friendly energy vehicles, is increasing recently. This trend is due to the global warming problem, and the global atmosphere for the withdrawal of internal combustion engine vehicles will increase. On the other hand, the supply of electric vehicles is steadily increasing every year, and its share will increase further in the future.

전기자동차에 있어서 빼놓을 수 없는 중요한 요소가 바로 배터리인데, 전기자동차가 늘어나면서 배터리 원인에 의한 차량화재가 종종 발생되고 있다. 전기자동차의 화재 발생은 크게 충전중 또는 주행중 발생할 수 있다. An important element in electric vehicles is the battery. As the number of electric vehicles increases, vehicle fires often occur due to battery causes. Electric vehicle fires can occur while charging or driving.

만약 전기자동차에서 화재가 발생할 경우 소화기 등으로 1차적으로 화재를 진압하였다 하더라도 시간이 지나면서 배터리에서 2차적으로 화재가 발생될 수 있기 때문에 일반적으로 1차적 화재진압 후 되도록 24시간 이내에 배터리를 안정화시키는 작업이 필수적으로 이루어져야 한다. In the event of a fire in an electric vehicle, even if the fire is first extinguished with a fire extinguisher, etc., a secondary fire may occur in the battery over time. In general, it is recommended to stabilize the battery within 24 hours after the primary fire extinguishing. work must be done.

그런데 배터리는 차량의 내부에 보호되어 있기 때문에 소화기나 물 분사 등으로 화재를 진압하더라도 배터리에 대한 안정화 작업은 완벽하게 처리하기에 어려움이 뒤따른다. However, since the battery is protected inside the vehicle, even if the fire is extinguished with a fire extinguisher or water spray, it is difficult to completely handle the stabilization work on the battery.

특히 전기자동차의 화재 중 충전 중 화재가 발생하는 경우는 충전설비가 설치되어 있는 주차장일 확률이 높은데 이럴 경우 주변 차량과의 간격이 조밀하기 때문에 인접한 차량의 간섭에 의해 배터리를 안정화시키는 작업에 더욱 어려움이 따른다. In particular, if a fire occurs while charging an electric vehicle during a fire, it is highly likely that it is a parking lot where a charging facility is installed. This follows.

이하 본 발명의 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3을 함께 참조하면, 본 발명의 실시 예에 따른 1 to 3 together, according to an embodiment of the present invention

전기자동차 화재시 배터리를 안정화시키기 위한 냉각조(2)(이하 간단히 ‘냉각조’라고도 함)는 크게 방수판체(10)와 공기주입형 벽튜브(20) 간의 결합으로 구성된다. The cooling tank 2 (hereinafter also simply referred to as a 'cooling tank') for stabilizing the battery in case of a fire in an electric vehicle is largely composed of a coupling between the waterproof plate body 10 and the air-injected wall tube 20 .

먼저 방수판체(10)는 방수재질이 바람직하고 대략 직사각형태를 가진다. 방수판체(10)는 전기자동차 하부에 펼쳐지는 것으로서 리프팅백(9)과 같은 리프팅 수단에 의해 전기자동차의 바퀴가 바닥면으로부터 들려지면 전기자동차를 중심으로 바닥면에 넓게 펼쳐지게 된다. First, the waterproof plate body 10 is preferably made of a waterproof material and has an approximately rectangular shape. The waterproof plate body 10 is spread under the electric vehicle, and when the wheel of the electric vehicle is lifted from the floor by a lifting means such as a lifting bag 9, it is spread widely on the floor around the electric vehicle.

상기 리프팅백(9)은 견고한 고무재질로 공기를 불어넣으면 팽창된다. 이러한 리프팅백(9)은 전기자동차의 앞뒤의 범퍼의 하부에 각각 위치시키고 공기를 불어 넣음에 따라 팽창되어 앞뒤 바퀴가 모두 들려지게 된다. 리프팅백(9)의 사이즈가 작을 경우 별도의 받침대(9a)를 이용할 수 있다. The lifting bag 9 is made of a solid rubber material and is inflated when air is blown. These lifting bags 9 are respectively positioned under the front and rear bumpers of the electric vehicle and expand as air is blown so that both the front and rear wheels are lifted. When the size of the lifting bag 9 is small, a separate pedestal 9a may be used.

리프팅백(9)에 의해 전기자동차의 바퀴가 바닥면으로부터 들려지면 방수판체(10)를 펼쳐 전기자동차의 바퀴 바깥쪽으로 이동되게 하고, 그 후 리프팅백(9) 내부의 바람을 빼낸 후 제거한다. 리프팅백(9)이 제거되면 방수판체(10) 상부에 전기자동차의 바퀴가 안착된 상태가 되며 아울러 전기자동차를 중심으로 방수판체(10)를 넓게 펼칠 수 있게 된다. When the wheel of the electric vehicle is lifted from the floor by the lifting bag 9, the waterproof plate body 10 is unfolded to move to the outside of the wheel of the electric vehicle, and then the wind inside the lifting bag 9 is blown out and then removed. When the lifting bag 9 is removed, the wheels of the electric vehicle are seated on the upper part of the waterproof plate body 10 , and the waterproof plate body 10 can be widely spread around the electric vehicle.

이러한 상태에서 도 4a의 ④와 같이 방수판체(10)를 펼쳐 전기자동차를 덮는다. 방수판체(10)를 덮음으로써 여전히 남아있는 불씨를 잠잠해지도록 하고 추가적으로 확산될 수 있는 화재를 방지할 수 있게 된다. 또한 후속적으로 이루어질 공기주입형 벽튜브(20)의 결합도 용이하도록 하고 작업자의 안정성도 어느 정도 확보할 수 있게 된다. In this state, as shown in ④ of FIG. 4A, the waterproof plate body 10 is spread to cover the electric vehicle. By covering the waterproof plate body 10, it is possible to silence the still remaining embers and to prevent further spread of fire. In addition, it is also possible to facilitate the coupling of the air-injected wall tube 20 to be subsequently made, and to ensure the safety of the operator to some extent.

다음으로 공기가 채워진 상태의 중앙 홀(20a)를 갖는 공기주입형 벽튜브(20)를 전기자동차를 통과하여 내려와 바닥면(7)에 안착되게 함으로써 전기자동차를 빙르는 임시 벽면이 형성되게 구성한다. 공기주입형 벽튜브(20)는 외곽 벽부에 공기주입 및 배출구(22)를 구성하여 공기를 주입 및 배출토록 하며, 별도의 과압방지구도 구성할 수 있다. Next, an air-injected wall tube 20 having a central hole 20a in a state of being filled with air passes through the electric vehicle and descends to be seated on the floor surface 7 to form a temporary wall surface that surrounds the electric vehicle. . The air injection type wall tube 20 configures the air injection and discharge port 22 on the outer wall to inject and discharge air, and a separate overpressure prevention device may also be configured.

상기 공기주입형 벽튜브(20)에 공기주입 작업은 고압의 가스가 채워진 가스통이나 컴프레셔 등을 구비함으로 구현할 수 있다. 이러한 공기주입 작업은 상기 리프팅백(9)의 공기 주입시에도 동일하게 적용 가능토록 하면 효율적인 운영이 된다. The air injection operation into the air injection type wall tube 20 can be implemented by providing a gas cylinder or a compressor filled with high-pressure gas. Such an air injection operation becomes an efficient operation if it is equally applicable to the air injection of the lifting bag 9 .

상기 상태에서 전기자동차를 덮고 있는 방수판체(10)의 가장자리 부분을 펼쳐 공기주입형 벽튜브(20)의 벽안쪽에서 벽바깥쪽으로 넘겨 벽이 감싸지도록 형성하면, 방수판체(10)와 공기주입형 벽튜브(2) 서로 간의 연합으로 전기자동차를 담는 형태의 냉각조(수조)의 구축이 완료된다. 그리고 구축된 냉각조 내부로 물을 채우면 전기자동차의 배터리가 침수되어 배터리가 안정화된다. In the above state, if the edge portion of the waterproof plate body 10 covering the electric vehicle is expanded and passed from the inside of the wall of the air-injected wall tube 20 to the outside of the wall to surround the wall, the waterproofing plate body 10 and the air-injected wall The tube (2) is combined with each other to complete the construction of a cooling tank (water tank) in the form of containing an electric vehicle. When water is filled into the built-in cooling tank, the battery of the electric vehicle is submerged and the battery is stabilized.

도 4(도 4a 및 도 4b)를 참고하여 냉각조 구축과정에 대하여 다시 정리하면 다음과 같다. Referring to FIG. 4 ( FIGS. 4A and 4B ), the cooling tank construction process is summarized as follows.

도 4a의 ⓛ과 같이 리프팅백(9)을 전기자동차의 앞뒤 범퍼 하부에 위치키시고 공기를 불어넣어 전기자동차의 바퀴가 모두 들려지게 한다. 그리고 ②와 같이 전기자동차의 하부에 방수판체(10)를 위치시키는데 방수판체(10)를 전기자동차 하부에 위치시키는 과정은 상기 ⓛ의 과정에 앞서 하거나 동시 다발적으로 할 수도 있다. As shown in ⓛ of FIG. 4A, the lifting bag 9 is positioned under the front and rear bumpers of the electric vehicle, and air is blown so that all the wheels of the electric vehicle are lifted. And, as shown in ②, the waterproof plate body 10 is positioned on the lower part of the electric vehicle.

다음으로 ③과 같이 방수판체(10)를 일부 펼쳐 전기자동차의 바퀴 외곽쪽으로 이동되게 하고 그 후 ④와 같이 리프팅백(9) 내부의 바람을 빼낸 후 제거한다. 리프팅백(9) 제거에 따라 방수판체(10) 상부에 전기자동차가 올려진 상태가 되며 아울러 전기자동차를 중심으로 방수판체(10)를 넓게 펼칠 수 있게 되므로, 방수판체(10)를 펼쳐 전기자동차를 덮는다. Next, as shown in ③, partially unfold the waterproof plate 10 to move it to the outside of the wheel of the electric vehicle, and then remove the wind from the inside of the lifting bag 9 as shown in ④. As the lifting bag 9 is removed, the electric vehicle is placed on top of the waterproof plate body 10, and the waterproof plate body 10 can be widely spread around the electric vehicle. cover the

다음으로 도 4b의 ⑤와 같이 공기가 채워진 상태의 공기주입형 벽튜브(20)를 이용하여 방수판체(10)로 덮여진 전기자동차를 빙 둘러싸도록 위치시키고, ⑥과 같이 방수판체(10)를 펼쳐 공기주입형 벽튜브(20)의 안쪽에서 바깥쪽으로 감싸지도록 한다. 이러한 과정에 의하여 냉각조(수조)가 구축되면 냉각조 내부로 물을 채워 전기자동차의 배터리가 침수되게 하여 안정화시킨다. Next, the electric vehicle covered with the waterproof plate body 10 is positioned to surround the electric vehicle covered with the waterproof plate body 10 using the air-injected wall tube 20 in a state of being filled with air as shown in ⑤ of FIG. 4B, and the waterproof plate body 10 is installed as shown in ⑥ It spreads so that it is wrapped from the inside to the outside of the inflatable wall tube (20). When a cooling tank (water tank) is built by this process, water is filled into the cooling tank to submerge the battery of the electric vehicle to stabilize it.

한편, 본 발명에서는 도면에 별도로 도시하지는 않았지만 전기자동차를 중심으로 공기주입형 튜브(20) 결합하기에 앞서 방수판체(10)를 전기자동차를 중심으로 바닥면에 완전히 펼친 후 방수판체(10) 상부에 공기주입형 튜브(20)가 얹혀지도록 결합하며, 상기 상태에서 방수판체(10)를 공기주입형 벽튜브(2)의 바깥쪽에서 안쪽으로 감싸지도록 함으로써 전기자동차를 담는 형태의 수조가 구축되게 할 수도 있다. 하지만 이러한 방법은 앞선 방법과 비교할 때 앞선 방법이 더 바람직하다고 할 수 있다. On the other hand, in the present invention, although not separately shown in the drawings, the waterproof plate body 10 is completely spread on the floor surface centered on the electric vehicle before the air injection type tube 20 is coupled to the electric vehicle, and then the waterproof plate body 10 upper part It is combined so that the air-injected tube 20 is placed on it, and in the above state, the waterproof plate body 10 is wrapped from the outside to the inside of the air-injected wall tube 2 to construct a water tank in the form of containing an electric vehicle. may be However, it can be said that this method is more preferable than the previous method.

공기주입형 벽튜브(20)의 외곽 벽부에는 다 수개의 손잡이(24)를 구성하여 수조의 구축작업을 용이하도록 한다. A plurality of handles 24 are configured on the outer wall of the air-injected wall tube 20 to facilitate the construction of the water tank.

도 5는 공기주입형 벽튜브(20)에 공기가 빠진 상태를 도시한 것이다. 이러한 공기주입형 벽튜브(20)는 접을 수 있으므로 방수판체(10)와 마찬가지로 이동이나 보관에 유리하다. 5 shows a state in which air is removed from the air-injected wall tube 20 . Since this air-injected wall tube 20 is foldable, it is advantageous for movement or storage like the waterproof plate body 10 .
