Description

차량의 고전압배터리 에어브리더{AIR BREATHER FOR HIGH VOLTAGE BATTERY OF VEHICLE}High voltage battery air breather for vehicle {AIR BREATHER FOR HIGH VOLTAGE BATTERY OF VEHICLE}

본 발명은 차량의 고전압배터리 에어브리더에 관한 것으로서, 보다 상세하게는 차량의 실외에 장착되어 외부로부터 고전압배터리 내부로 물이 침투하지 못하도록 하는 수밀성을 가지면서도 고전압배터리 내부에서 발생될 수 있는 가스를 대기중으로 방출시킬 수 있도록 하는 에어브리더의 구조에 관한 기술이다.The present invention relates to a high-voltage battery air breather of a vehicle, and more particularly, to be mounted outside the vehicle to have watertightness to prevent water from penetrating into the high-voltage battery from the outside, while at the same time waiting for gas that can be generated inside the high-voltage battery. It is a technology related to the structure of an air breather that allows it to be released into the air.

최근에 개발되고 있는 하이브리드 차량이나 전기차량 등에는 고전압배터리가 사용되며, 현재까지는 대체로 고전압배터리의 냉각을 위해 공기 등의 입구 및 출구를 구비하여 고전압배터리가 완전히 밀폐된 구조는 아니었지만, 향후 고전압배터리를 구성하는 배터리셀의 성능 및 발열특성 향상으로 별도의 냉각장치나 구조를 구성하지 않고 차량의 실외에 장착된 상태에서 자연냉각에 의해 고전압배터리의 냉각문제가 해결될 수 있을 것이다.
High voltage batteries are used in hybrid vehicles and electric vehicles that are being developed recently. Until now, high voltage batteries were not completely enclosed by having inlets and outlets such as air for cooling high voltage batteries. By improving the performance and heat generation characteristics of the battery cells constituting the cooling system of the high voltage battery can be solved by the natural cooling in the state mounted outside the vehicle without configuring a separate cooling device or structure.

그런데, 상기한 바와 같이 고전압배터리가 차량의 외부에 장착되는 경우에는 외부로부터 고전압배터리의 내부로 물이 침투하지 못하도록 완전한 수밀 기능이 확보되어야 하는데, 이렇게 완전한 수밀성을 담보할 정도로 밀폐된 고전압배터리 내부에서 예기치 못한 이상 동작이 발생하면, 배터리셀에서 가스가 발생되어 고전압배터리 내부에 압력이 누적 및 상승할 수 있고, 나아가 고전압배터리의 폭발이나 케이스의 변형 등을 초래하게 된다.
However, when the high voltage battery is mounted on the outside of the vehicle as described above, the watertight function must be secured to prevent water from penetrating into the high voltage battery from the outside. When an unexpected abnormal operation occurs, gas may be generated in the battery cell, and pressure may accumulate and increase in the high voltage battery, and further, explosion or deformation of the high voltage battery may be caused.

따라서, 차량 외부에 장착되는 고전압배터리에 그 수밀성을 담보하면서도 고전압배터리 내부에서 발생된 가스가 외부로 용이하게 배출될 수 있도록 할 필요가 있다.
Therefore, it is necessary to ensure that the gas generated inside the high voltage battery can be easily discharged to the outside while ensuring the watertightness to the high voltage battery mounted on the outside of the vehicle.

상기의 발명의 배경이 되는 기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.The matters described as the background of the above-described invention are merely for the purpose of improving the understanding of the background of the present invention, and are accepted as acknowledging that they correspond to the prior art already known to those skilled in the art. I will not.
