BATTERY PACK GAS DISCHARGING APPARATUS FOR VEHICLE

The present invention provides an apparatus for discharging gas of a battery pack for a vehicle, comprising: a vacuum pump for forming negative pressure on a vacuum reservoir for a brake, which configures a vacuum state in a brake booster; the vacuum reservoir for a battery pack with predetermined negative pressure formed by the vacuum pump so as to absorb gas from a battery pack when the gas is generated in the battery pack for providing power to a vehicle; a first control valve for selectively opening and closing a first air flow path for forming a path through which air of the vacuum reservoir for a brake is absorbed by the vacuum pump, and a second air flow path for forming a path through which the air of the vacuum reservoir for a battery pack is absorbed; and a second control valve for opening and closing a gas flow path for forming a path through which the gas is absorbed to the vacuum reservoir for a battery pack, in the battery pack. The objective of the present invention is to provide the apparatus for discharging gas of a battery pack for a vehicle, which can prevent gas from being introduced to the inside of the vehicle when the gas is generated in the battery pack. 본 발명은, 브레이크 부스터에 진공 상태를 조성하는 브레이크용 진공리저버에 부압을 형성시키는 진공펌프와, 진공펌프에 의해 내부에 소정의 부압이 형성되어, 차량에 전력을 제공하는 배터리팩에서 가스 발생시, 배터리팩으로부터 가스를 흡인하는 배터리팩용 진공리저버와, 진공펌프에 의해, 브레이크용 진공리저버의 공기가 흡인되는 경로를 형성하는 제1 공기유로와 배터리팩용 진공리저버의 공기가 흡인되는 경로를 형성하는 제2 공기유로를 선택적으로 개폐시키는 제1 제어밸브 및 배터리팩에서 배터리팩용 진공리저버로 가스가 흡인되는 경로를 형성하는 가스유로를 개폐시키는 제2 제어밸브를 포함하는 차량용 배터리 팩의 가스 배출장치를 제공할 수 있다.
