Modules within the energy storage unit can easily be mounted after the cabinet structure is in place to avoid heavy lifting of the sections, and also to avoid damage during a ship’s construction period. The cabinet structure protects against solid foreign objects and ingress of water. The Battery Management System (BMS) is developed to meet the highest requirements for maritime applications. The cells are monitored and logged for voltage, temperature and current. The redundant safety controller developed by KONGSBERG constantly monitors the temperature and has an independent safety shutdown. In addition, the BMS features active balancing during cycling, for optimal energy storage and battery life. Energy Storage Unit embraces the KONGSBERG multiple safety barrier principle. In case of thermal runaway in a cell or multiple cells, the safety systems prevents propagation. The propagation is limited and controlled by use of passive heat isolation, active air and liquid cooling. No flammable or toxic gasses are vented into the ambient space, but lead to open air or to a safe location with an independent ducting system. The first safety barrier is a passive heat insulation between cells to avoid thermal runaway propagation inside a battery module. The second barrier is automatic air cooling system th
