Description
본 발명은 배터리에 저장되어 있는 에너지로 주행에 필요한 동력을 얻는 전기자동차에서 배터리 화재로 인한 차량 손상을 최소화하고 인명 피해를 예방하기 위해 배터리 모듈에 코팅하여 사용하는 친환경 내화코팅제 조성물과 스프레이 코팅방법, 그리고 친환경 내화코팅제 조성물이 코팅되어 있는 배터리 모듈에 관한 것이다. The present invention provides an eco-friendly fire-resistant coating composition and a spray coating method for coating battery modules to minimize vehicle damage and prevent human casualties due to battery fire in electric vehicles that obtain the power necessary for driving with energy stored in the battery; And it relates to a battery module coated with an eco-friendly fire-resistant coating composition.
일반적으로 전기자동차에는 차량 구동을 위한 전기에너지를 공급하기 위해 배터리가 사용된다. Generally, batteries are used in electric vehicles to supply electrical energy to drive the vehicle.
이러한 배터리는 다수의 단위전지 또는 모듈을 연결하여 고전압을 만들 수 있는 배터리 팩이 구성되며, 이를 이용하여 높은 전력을 발생시킨다.These batteries consist of a battery pack that can create high voltage by connecting multiple unit cells or modules, and use this to generate high power.
즉, 배터리 팩에 저장된 에너지를 인버터를 통해 모터에 전달하여 차량 시동, 가속, 엔진 고효율점 운행 등에 사용하고, 엔진에서 잉여에너지가 발생하면 모터를 발전기로 이용하여 그 잉여 에너지를 배터리에 저장한다.In other words, the energy stored in the battery pack is transferred to the motor through an inverter and used for vehicle starting, acceleration, and engine operation at high efficiency points. When surplus energy is generated in the engine, the motor is used as a generator and the surplus energy is stored in the battery.
이와 같은 배터리는 사용 전류량이 상당히 크고, 그로 인해 내부에서 열이 많이 발생되기 때문에 배터리를 사용하는 전기자동차에서는 과전류 및 쇼트 등으로 인해 배터리에서 발생될 수 있는 화재를 예방하는 것이 무엇보다도 중요하다. Since these batteries use a fairly large amount of current and generate a lot of heat internally, it is most important to prevent fires that may occur in the battery due to overcurrent or short circuit in electric vehicles using batteries.
최근 국내외 친환경차 보급률이 증가하면서 전기자동차 시대로 접어들었다. Recently, as the penetration rate of eco-friendly vehicles has increased at home and abroad, we have entered the era of electric vehicles.
하지만, 전기자동차 수요는 꾸준히 증가하고 있는 반면 아직도 해결해야 할 숙제는 산더미처럼 쌓여 있다. However, while demand for electric vehicles is steadily increasing, there are still a mountain of tasks that need to be solved.
그 중에서 가장 큰 문제로 제기되는 것이 배터리 결함으로 인한 화재의 위험이다. Among them, the biggest problem raised is the risk of fire due to battery defects.
보통 전기자동차에는 모터와 배터리 등 각종 전자장비들이 포함되어 있기 때문에 누전 등의 이유로 화재가 발생할 가능성을 배제할 수는 없으며, 이러한 전기자동차의 화재는 대형 화재로 이어질 개연성이 크다는데 있다. Since electric vehicles usually contain various electronic equipment such as motors and batteries, the possibility of a fire occurring due to a short circuit or other reasons cannot be ruled out, and there is a high probability that a fire in such an electric vehicle will lead to a large-scale fire.
일 예로서, 전기자동차를 움직이는데 쓰이는 배터리는 주로 리튬 전지가 사용되는데, 리튬이나 나트륨, 칼륨, 세슘, 마그네슘처럼 반응성이 큰 가연성 금속은 금속화재가 발생할 위험성이 있으며, 금속화재의 경우 일반적인 화재처럼 물로 소화할 경우 화학반응으로 수소가 생성되어 자칫 수소폭발이 발생할 수 있기 때문에 굉장히 위험한 화재이다. As an example, the batteries used to power electric vehicles are mainly lithium batteries. Highly reactive combustible metals such as lithium, sodium, potassium, cesium, and magnesium have the risk of causing a metal fire, and in the case of a metal fire, it can be treated with water like a general fire. When extinguished, hydrogen is generated through a chemical reaction, which can lead to a hydrogen explosion, making it a very dangerous fire.
또한, 리튬 전지를 사용하는 배터리는 충방전 시 열이 발생하는 바, 이러한 열이 효과적으로 제거되지 못하고 축적되는 경우, 전지의 열화가 초래되고 안전성도 크게 훼손될 수 있으며, 특히, 전기자동차 등의 전원과 같이 고속 충방전 특성이 요구되는 전지에서는 순간적으로 고출력을 제공하는 과정에서 많은 발열과 부피 팽창이 수반되면서 화재의 위험에 노출되는 사례가 증가하고 있다. In addition, batteries using lithium batteries generate heat when charging and discharging. If this heat is not effectively removed and accumulates, battery deterioration may occur and safety may be greatly impaired. In particular, as a power source for electric vehicles, etc. In batteries that require high-speed charging and discharging characteristics, the risk of fire is increasing as a lot of heat is generated and volume expansion occurs in the process of providing instantaneous high output.
따라서, 본 발명은 이와 같은 점을 감안하여 안출한 것으로서, 전기자동차의 배터리 결함으로 인한 화재의 위험을 예방하기 위하여 배터리 모듈의 케이스, 배터리 팩 등에 실리콘 디옥사이드(SiO2; Silicon dioxide), 티타늄 디옥사이드(TiO2; Titanum dioxide), 실리콘카바이드(SiC; Silicon carbide), 질화붕소(BN; Boron nitride) 등과 같은 내화코팅제를 코팅하여 각 부품의 내화성능을 높여줌으로써, 폭발이나 화재 발생의 원인이 되는 발화를 억제할 수 있는 등 배터리 화재를 예방할 수 있고 배터리 발화 시에도 화재가 확산되는 것을 막을 수 있는 등 배터리 화재로 인한 위험을 감소시키면서 탑승자의 안전을 확보할 수 있는 친환경 내화코팅제 조성물과 스프레이 코팅방법, 그리고 친환경 내화코팅제 조성물이 코팅되어 있는 배터리 모듈을 제공하는데 그 목적이 있다.
