Marine propulsion systems were traditionally operated with internal combustion engines powered by fossil fuels. In order to increase energy conversion efficiency and decrease greenhouse emissions electrified powertrains are a considerable solution to complement or even replace conventional combustion engines. In this context, fuels cells and lithium-ion-batteries can be used as generators and electrical machines for the propulsion.
Supplementary to the modelling and the numerical simulation of marine propulsion systems, test benches with part of the components physically present and others emulated as Hardware in the Loop (HiL) can be used to validate the simulation results. Furthermore, control algorithms and failure scenarios can be tested with part of the hardware being available.
