For some marine applications, battery systems based on the current monotype topologies are significantly oversized due to variable operational profiles and long lifespan requirements. This paper deals with the battery hybrid energy storage system (HESS) for an electric harbor tug to optimize the size of the battery system.
This section summarizes the recommendations identified for the operation and maintenance of maritime and offshore battery systems. The normal use of the batteries should be fully automatic. There should be no need for manual interaction. Table 8-1 gives recommendations towards a generic operational strategy.
Main priorities for a battery system for maritime applications are safety, reliability and sufficient life for the system to be economically feasible. All components in the battery systems must be of good quality to secure a safe and reliable system throughout the system’s lifetime.
The cost of the HESS topology is compared with the monotype battery topologies with only HE or HP battery types as the baseline systems. Finally, the total system loss and battery cell weight for the most cost-effective HESS are compared with the baseline systems.
