According to an embodiment of the present invention, a battery protection circuit device of an underwater box prevents a transient phenomenon when a circuit breaker is inserted and opened to apply power to a battery of an underwater box. The battery protection circuit device comprises: a resistor for preventing a transient phenomenon by reducing an excessive inrush current that may occur when power is applied for initial charging of the battery in a fully discharged state of the battery; and a coil for supplying power to the battery by being constantly magnetically excited for stable power supply to the battery after the initial charging of the battery.

    본 발명의 일 실시예에 따르는 수중함의 배터리 보호회로 장치는 수중함의 배터리에 전원인가를 위한 차단기 투입 및 개방 시 과도현상을 방지하는 수중함의 배터리 보호회로 장치로서, 상기 배터리의 완전 방전상태에서 상기 배터리의 초기충전을 위해 전원인가 시 발생 가능한 과도돌입전류를 감소시켜 과도현상을 방지하는 저항, 및 상기 배터리의 초기충전 이후에 상기 배터리로의 안정적인 전원공급을 위해 상시 자기여자 되어 상기 배터리에 전원을 공급하는 코일을 포함한다.
