Title
(KO) 안전성이 개선된 배터리 모듈, 이러한 배터리 모듈을 포함하는 배터리 팩 및 이러한 배터리 팩을 포함하는 자동차
Abstract
(KO)
온도 상승시 전류를 차단할 수 있어 안전성이 향상된 배터리 모듈, 이러한 배터리 모듈을 포함하는 배터리 팩 및 이러한 배터리 팩을 포함하는 자동차를 제공하는 것이다. 본 발명에 따른 배터리 모듈은, 길이와 너비에 비해 두께가 얇은 대략 판상형이고 길이 방향을 따르는 좌측면과 우측면에 각각 선형 홈이 마련된 버스바; 및 상기 버스바의 좌측면과 우측면에 각각 위치하고 상기 홈에 각자의 전극 리드가 끼워져 물리적 접촉됨으로써 상기 버스바를 가운데에 두고 서로 전기적 연결되어 있는 배터리 셀들을 포함하며, 상기 홈은 일정 온도 이상에서 두께 방향 크기가 증가해서 상기 전극 리드와 상기 버스바 사이의 물리적 접촉이 해제됨으로써 상기 배터리 셀들간 전기적 연결이 해제되도록 하는 것이다.
