The present invention relates to a fire extinguishing system for an electric vehicle in charging which can effectively extinguish a fire by preventing thermal runaway to prevent the fire from being transferred to other cells of a battery. The fire extinguishing system for an electric vehicle in charging comprises: fire water injection parts separated from each other, buried and installed on a floor surface on which an electric vehicle in charging connected to a charger is positioned, and provided with a fine spray nozzle with a head installed to face the bottom surface of the electric vehicle; a sensing part having temperature sensors separated from each other and arranged on the floor surface to sense the battery temperature of the electric vehicle; and a control part having a controller opening and closing a valve of a fire water supply pipe connected to the fine spray nozzle based on information generated by the temperature sensors to regulate the supply of fire water to the fine spray nozzle. The fine spray nozzle finely sprays the fire water toward the battery by projecting the head above the floor surface by the water pressure of the fire water supplied as the controller opens the valve of the fire water supply pipe when the temperature of the battery sensed by the temperature sensors exceeds a preset temperature.

    본 발명은, 충전기에 연결된 충전중의 전기자동차가 위치하는 바닥면에 간격을 두고 매립 설치되되, 헤드가 상기 전기자동차 저면을 마주하게 설치되는 미세분무 노즐을 구비하는 소화수분사부; 상기 바닥면에 간격을 두고 배치되어 상기 전기자동차의 배터리 온도를 감지하는 온도센서를 구비하는 감지부; 및 상기 온도센서가 생성하는 정보를 기반으로 상기 미세분무 노즐에 연결되는 소화수공급관의 밸브를 개폐하여 상기 미세분무 노즐로의 소화수 공급을 단속하는 제어기를 구비하는 제어부;를 포함하고, 상기 미세분무 노즐은 상기 온도센서가 감지한 상기 배터리의 온도가 사전 설정된 온도를 초과할 때 상기 제어기가 상기 소화수공급관의 상기 밸브를 개방함에 따라 공급되는 상기 소화수의 수압에 의해 상기 헤드가 상기 바닥면 상부로 돌출되어 상기 배터리를 향해 상기 소화수를 미세분무하는 것을 특징으로 하는 충전중 전기자동차 화재진압 시스템에 관한 것이다.
