The present invention proposes a fire extinguishing device for extinguishing a fire inside a battery pack of an electric vehicle. The fire extinguishing device of the present invention includes: a venting device (20) installed in a battery pack casing (10) of an electric vehicle; and a fluid guide pipe (30) connected to the venting device (20) and extending to the outside. Here, the venting device (20) converts the inside and outside of the battery pack casing (10) into a state of communication based on a force due to pressure applied inside or outside thereof, and a rupture plate may be used. In addition, since the extinguishing agent can be supplied from the outside to the inside of the battery pack casing (10) through the fluid guide pipe (30), the fire extinguishing device of the present invention will be useful for rapid and efficient fire extinguishment.

    본 발명은 전기 자동차의 배터리팩 내부의 화재를 진압하는 소화장치를 제안한다. 본 발명 소화장치는, 전기자동차의 배터리팩 케이싱(10)에 설치되는 벤팅 디바이스(20)와, 벤팅 디바이스(20)와 연결되어 외부로 연장되는 유체 가이드 파이프(30)를 포함한다. 여기서 벤팅 디바이스(20)는 그 내부 또는 외부에서 작용하는 압력에 의한 힘에 기초하여 배터리팩 케이싱(10)의 내외부를 연통상태로 변환시키는 것으로, 파열판을 이용할 수 있다. 그리고 유체 가이드 파이프(30)를 통하여 외부에서 배터리팩 케이싱(10) 내부로 소화액을 공급할 수 있어서 신속하고 효율적인 화재 진압에 유용할 것이다.
