Abstract

As regulations on environmental pollution of ships have been strengthened, interest in smart ships such as electric propulsion ships equipped with hybrid power systems is increasing. Since batteries used in electric propulsion ships have a larger capacity than batteries used in vehicles, the price is high and maintenance is considered important. The ship's battery is manufactured as an integral type and is managed by the battery management system, and the maintenance and repair of the battery is performed through the replacement of the battery. we design and implement a battery module and a control algorithm using pre-cell for easy battery management. In addition, a controller is designed to transmit the data necessary for the electric propulsion ship power system control to the power control system. When a battery to which the corresponding spare-cell is applied is used, the stability of the ship and the battery system is increased, and it can have an advantage in terms of maintenance and repair.

최근 선박의 환경오염에 대한 규제가 강화됨에 따라 하이브리드형 전력체계를 갖춘 전기 추진 선박과 같은 스마트 선박에 대한 관심이 높아지고 있다. 전기추진선박에서 사용되는 배터리는 차량 등에 사용되는 배터리보다 용량이 크므로, 가격이 높아지고 유지 보수 측면이 중요하게 여겨진다. 선박용 배터리는 일체형으로 제작되어 배터리관리 시스템에 의해 관리되며, 배터리의 유지·보수는 배터리의 교체를 통하여 이루어진다. 본 연구에서는 배터리의 용이한 관리를 위해서 예비-셀을 적용한 배터리 모듈과 제어 알고리즘을 설계 및 구현한다. 또한, 전기추진선박 전력 체계 제어에 필요한 데이터를 전력 제어 시스템에 송신 할 수 있도록 제어기를 설계한다. 해당 예비-셀을 적용한 배터리를 사용할 경우 선박 및 배터리 시스템의 안정성이 높아지며, 유지 및 보수 측면에서 이점을 가질 수 있다.
