The present invention relates to a high voltage battery system for an electric vehicle capable of securing fail safety at the room and high temperature short circuit of a high voltage battery in an electric vehicle. The present invention implements a new-type safety device which can safe fail through the structure improvement of a cell tap which locally reduces a conduction cross section to a level that an instant hot furnace conduction part is molten (evaporated) at battery short circuit. Thereby, the high voltage battery system for an electric vehicle can secure fail safe at the room and high temperature short circuit of a high voltage battery and can prevent secondary damage due to fire in car repair or crash.

    본 발명은 전기자동차에서 고전압배터리 상온단락 및 고온단락 시 페일 세이프(Fail safety)를 확보할 수 있는 고전압배터리 시스템에 관한 것이다. 본 발명은 배터리 단락 시 순간 고열로 통전부가 용단(증발)되는 수준으로 통전 단면적을 국부적으로 축소한 셀 탭의 구조개선을 통해서 세이프 페일을 확보할 수 있는 새로운 형태의 안전장치를 구현함으로써, 고전압 배터리 상온단락 및 고온단락 시 페일 세이프를 확보할 수 있는 등 차량 충돌 시 또는 정비 시 화재로 인한 2차적인 피해를 예방할 수 있는 전기자동차의 고전압배터리 시스템을 제공한다.
