Abstract: A method of integrating, optimizing and combining in a marine hybrid system, the operation of one or more variable speed high voltage direct current (HVDC) generator(s), one or more energy storage units and a combination of one or more HVDC parallel hybrid and serial hybrid propulsion systems through use of an Energy Management Computer. One aspect of the invention involves the application of logic programming to automate the optimization and the operation of the Internal Combustion Engines (ICE) so that whenever the system requires their usage, they are operated at optimum efficiency conditions. For an ICE to operate at peak efficiency a combination of a large energy storage unit used as a buffer combined with a mixture of both a serial and a parallel hybrid system is used.

Abstract: A method of integrating, optimizing and combining in a marine electric or hybrid system, the operation and safety of one or more energy storage units, a combination of one or more electric outboard(s) and ICE outboard(s) in a propulsion systems through use of an Energy Management Computer. One aspect of the invention involves the application of logic programming to automate the optimization and the operation of the Internal Combustion Engines (STANDARD OUTBOARD) so that whenever the system requires their usage, they are operated at optimum efficiency conditions. For a STANDARD OUTBOARD to operate at peak efficiency a combination of a large energy storage unit used as a buffer combined with electric outboard(s) is used.
