Benefits of technology

[0005]One aspect of at least one of the inventions disclosed herein includes the utilization of automation to mix and match different technologies in a transparent fashion so that a normal unskilled user is able to operate a relatively complex marine vessel comprised of one or many electric inboard or outboards combined or not with one or many ICE propulsion engines, thereby reducing (or eliminating in certain reg

Problems solved by technology

As in the automotive industry, the issues of ample electric energy storage is not yet resolved, whether due to cost, volume or weight.
One of the difficulties in the development of high-powered (50 hp-300 hp) outboard engines, is that high voltage (240-600 volts) is more optimal for obtaining reasonable efficiencies, heat or current carrying reasons, creating a challenge to develop systems that are safe, reliable a

Example

[0031]Electric only operation is the most elegant, simple and economical, but until the energy storage issues are resolved, (cost and energy density), it may require recharging with a generator that uses petroleum products and / or with wind / water generators, solar panels, fuel cells or shore based power sources. This rapidly increases the cost and complexity of this type of system.

[0032]Even if battery only electric propulsion is extremely efficient at low speed and for low speed maneuvering, a large part of the market still demands the capability to go at high speed (even if for limited time). Commercial, pleasure fishing and diving operators want to go at high speed to their temporary destination and revert to low speed for hours or days before coming back at high speed to offload their expensive and / or time sensitive cargo, so that they can do it all over again.

[0033]Therefore, a way to automate the combination of the current technologies and greatly increase efficiency at a usefu...

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.

Description

RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Application No. 61 / 760,373, filed Feb. 4, 2013, the entire content of which is hereby expressly incorporated by reference.FIELD OF THE INVENTIONS[0002]The present inventions generally relate to marine electric propulsion outboard motors. Some embodiments include electric outboard motors rated from 50 hp to 300 hp that use high voltage (240-600 volts) for operation as well as marine hybrid propulsion systems. Some embodiments include definition, programming, parameterization and safety systems of an electronic management device, such as a computer, to interface, integrate, optimize, automate and simplify the operation of one or more electric outboards and associated energy storage units. One or more of such electric outboard motors can also be used in combination with one or more ICE (Internal Combustion Engine) powered outboard propulsion systems.BACKGROUND OF THE INVENTIONS[0003]With the advent of...
