Benefits of technology

The patent text describes a system that can select between two control algorithms to maximize either the electric power generated by an auxiliary power source or the fuel economy of the prime mover. This system is designed to optimize the performance of electric vehicles.

Problems solved by technology

A large OEG can consume significant torque from the engine and can compromise its ability to drive the primary load (i.e., the propulsion system).

Embodiment Construction

[0036]The application is described in the context of an auxiliary power generation device utilized on a marine vessel. It will be appreciated, however, that aspects of the invention have utility on any vehicle that includes ancillary equipment, including work trucks, ambulances, recreational vehicles, etc. As used herein, ancillary equipment is defined as any onboard equipment that is above and beyond what's strictly necessary for the vessel / vehicles mobility.

[0037]A method, system and apparatus in accordance with the present invention provide a means for delivering electric power to a marine vessel in an efficient and convenient manner. In accordance with the invention, a prime mover, such as a diesel engine or the like, includes, in addition to a primary electric power generation device, an auxiliary electrical power generation device (AEPGD—also referred to as an on-engine generator or OEG) for providing electric power to operate appliances, convenience outlets, etc. of the marin...

Abstract

An auxiliary electric power device, which is coupled to a prime mover, provides electric power to convenience outlets, appliances, and heating cooling units. Based on a mode of a transmission coupled to the prime mover, one of a plurality of control schemes is selected to control the power provided by the auxiliary electric power device.

Description

TECHNICAL FIELD[0001]The present disclosure relates generally to electrical power generation. More specifically, the present disclosure relates to a method and apparatus for optimizing electric power generation of an on-engine electric power generator.BACKGROUND INFORMATION[0002]In most conventional marine power systems, an engine, such as a diesel or gasoline engine, provides power to propel the marine vessel in the water. The prime mover also drives an alternator for providing limited electric power to operate the engine, any accessories of the engine and other low power 12V item on the vessel such as lighting, radios etc. For convenience power, such as 120 volt power, a separate electric power generation system is typically provided. The separate electric power generation system can include an additional prime mover, such as a small diesel, gasoline, or other type of internal combustion engine, and an electric machine, such as an alternator or generator. The electric power genera...
