The Hybrid Power Unit can be installed between the ICE and the sail drive as the figure below or between the ICE and the axis line.
The Efesto Hybrid Power Unit can be installed on any gasoline and diesel engines with a power up to 400 kW.
The double shaft architecture allows to use the electric motor always at its optimal speed, independently from the internal combustion engine maximum rpm.
The system features two clutches one for connect/disconnect the main shaft and one for connect/disconnect the electric motor: this enable to mechanically disconnect the electric motor when ever it is not required to operate.
The Efesto Hybrid Power enables to operate the boat in different functioning modes:
Pure Electric mode
Sailing generation mode
While cruising in ports at reduced speed, in lakes or natural reserves, full electric propulsion means respect of the environment.
At anchor the usage of the energy stored in batteries during navigation allows to avoid the usage of the auxiliary generator highly contributing the marine environ- ment preservation.
In case of failure of the ICE the electric motor is a back up propulsion system.
Significant saving in fuel consumption by navigating in pure electric mode.
Possibility to reduce the size of the ICE because the extra boost is provided by the
