WORLDWIDE FIRST SERIALIZED
HYBRID PROPULSION SYSTEM FOR PLEASURE BOATS

The environmentally friendly HYBRID SOLUTION marks a new
chapter in the history of pleasure boat propulsion systems. It not
only assures zero emission and low speed manoeuvring in harbours, noiseless drive on inland waters and nature reserves, but also eliminates the need for separate generator units for other onboard equipment.

The “zero emission” electric drive mode allows a speed of 5 knots using solely electric propulsion and switches to the combustion engine with an easy turn of the ignition key.

The ingenious propulsion then gets “boosted” by the electric drive
and enables quicker acceleration, lowering fuel consumption,
improving response and dynamics.

Significantly reduced maintenance costs and improved ease of service are further irrevocable arguments that STEYR MOTORS is introducing a serious technological novelty.

The STEYR MOTORS HYBRID can be installed on all engines and drive combinations.

THE ELECTRIC MOTOR OPERATES IN 4 MODES:

STARTER MODE
In Starter Mode, the combustion engine can be started with the
electric motor. The conventional starter motor can be eliminated
or will remain redundant.

GENERATOR MODE
In Generator Mode, the extended battery pack is optimised and
charged.

ELECTRIC CRUISE MODE
In Electric Cruise Mode, the boat is driven purely by the electric
motor. The battery pack is constantly monitored on its state of
charge and battery condition. This is brought to the attention
of the driver through the STEYR CONTROL CENTER (SCC).

BOOST MODE
In the lower speed range, depending on dynamic requirements
of the driver and the battery condition, the Boost Mode is used
and the combustion engine is then supported by the massive
torque of the electric motor.

The e-motor supports the coupling
and decoupling of the combustion engine. An improved response
of the drive unit occurs through the boost mode.

The STEYR ELECTRONIC CONTROL (SEC) unit forwards the
driver demands via CAN protocol to the engine control unit
(ECU) and hybrid control unit (HCU). Both control units regulate
the torque composition of drive units depending on dynamic
requirement.

At the same time, the condition of the components(batteries, e-motor, combustion engine, environmental conditions)is monitored through the control units.

The control units have adjustable functions and engine characteristics in order to coordinate all drive train variants to the driver’s demands in the appropriate boat.
