摘要： A modular hybrid propulsion unit is disclosed that is mountable to a watercraft. According to an example, the modular hybrid propulsion unit includes a housing configured to fit within a complementary housing receiver on a topside of the watercraft, and a rotational output coupling configured to rotationally engage with a rotational input coupling for a propeller of the watercraft. The propulsion unit further includes an electric motor within the housing, the electric motor having a motor shaft connected to the rotational output coupling for providing an electrically powered rotational input to the rotational output coupling. The propulsion unit further includes a crank having one or more crank arms. The crank is connected to the rotational output coupling for providing a human powered rotational input to the rotational output coupling independent of the electrically powered rotational input by the electric motor.

摘要： A ship propulsion system provides a first power transmission device that transmits power from an internal combustion engine to a propeller, a second power transmission device that transmits power from an electric motor to a propeller and that is mounted to the hull so as to be able to turn up and down independently from the first power transmission device, an actuator for causing the second power transmission device to turn up and down, and a control device. The control device is configured so as to be able to select a first drive mode in which the internal combustion engine is driven and the electric motor is not driven, and a second drive mode in which the internal combustion engine is not driven and the electric motor is driven. When the first drive mode is selected, the actuator is operated so that the second power transmission device turns up.

摘要： A method is provided for enhancing fuel efficiency in an integrated hybrid power system for a marine vessel, the integrated hybrid power system including multiple energy storage units and at least one engine-driven power generator coupled with a power distribution grid. The method includes: determining whether a consumer load on the power distribution grid is greater than a rated maximum efficiency loading of the power generator; starting the power generator when the consumer load is greater than the maximum efficiency loading and/or a charge level of the energy storage units is below a lower threshold value; maintaining a constant load on the power generator equal to the maximum efficiency loading despite fluctuations in consumer load; and shutting down the power generator when the consumer load is less than or equal to the maximum efficiency loading and the charge level of the energy storage units is greater than or equal to the lower threshold value.
