The present invention relates to a battery fire prevention system for an electric automobile. When charging a battery of the electric automobile, a high temperature which can occur under an abnormal condition is sensed. When a set temperature or higher is detected, a liquid nitrogen extinguishing liquid and a liquid wetting agent or a water are urgently injected into a battery casing to block thermal runaway at the casing interior of the battery. Therefore, a fire in the battery which is hardly extinguished at the exterior, a burnout of a vehicle due to an explosion, and a fire in surrounding vehicles can be prevented in advance. The battery fire prevention system for the electric automobile of the present invention comprises: a charging unit (100); a charging module (200); and a charging stand (300).

    본 발명은 전기자동차용 배터리 화재방지 시스템에 관한 것으로서, 전기자동차의 배터리 충전시 이상조건에서 발생할 수 있는 고온을 감지하고, 설정된 온도 이상이 감지되면 액화질소 소화액 및 액상의 침윤제 또는 물을 배터리 케이싱 내에 긴급 투입시켜 배터리의 케이싱 내부에서의 열폭주를 차단하여 외부에서는 진압하기 어려운 배터리의 화재, 폭발로 인한 차량의 전소, 주변 차량들의 화재를 미연에 방지할 수 있는 효과가 있다.
