Disclosed are a battery management system and an unmanned submarine having a battery flooding prevention function. The unmanned submarine comprises: a flooding determination module determining flooding; a flooding removal control module performing a control operation to remove water when the flooding is determined by the flooding determination module; and a valve opening/closing part installed in a BMS housing, and opening and closing a valve in accordance with the control of the flooding removal control module when the flooding is determined by the flooding determination module. With the above-stated battery management system and the unmanned submarine having a battery flooding prevention function, flooding is detected inside and outside the BMS housing in the unmanned submarine, the valve opening/closing of the BMS housing is controlled, and a pump is driven with power from a propeller to remove the flooding inside and outside the BMS, and, as a result, there can be an effect of maintaining operational capability of the unmanned submarine with respect to the flooding of the battery and flooding of the unmanned submarine. 배터리 관리 시스템 및 배터리의 침수 방지 기능을 구비하는 무인 잠수정이 개시된다. 무인 잠수정에 있어서, 침수를 판단하는 침수 판단 모듈; 상기 침수 판단 모듈에서 침수로 판단된 경우, 침수를 제거하도록 제어하는 침수 제거 제어 모듈; 상기 BMS 하우징에 설치되며, 상기 침수 판단 모듈에서 침수로 판단되는 경우 상기 침수 제거 제어 모듈의 제어에 따라 밸브(valve)를 개폐하는 밸브 개폐부를 구성한다. 상술한 배터리 관리 시스템 및 배터리의 침수 방지 기능을 구비하는 무인 잠수정에 의하면, 무인 잠수정 내 BMS 하우징 내부 및 외부의 침수를 감지하고 BMS 하우징의 밸브 개폐를 제어하고 추진기의 동력으로 펌프를 구동하여 BMS 내부 및 외부의 침수를 제거하도록 구성됨으로써, 배터리 침수 및 무인 잠수정 침수에 대한 무인 잠수정의 작전 능력을 유지할 수 있는 효과가 있다.
