The following operating modes form the basis for the application-specific adaptation of the system designs: performance, efficiency and comfort.
Energy for drive and power consumption provided by the battery
Emission-free and whisper-quiet – in zero-emission mode, the energy for the drive as well as the power consumption is provided exclusively by the battery. The battery can be charged in three ways: Shore connection in port, on-board gensets, main propulsion engines.
Reduce noise and exhaust gas emissions and save fuel
In diesel-electric mode, power supply and propulsion are provided by the existing on-board gensets and supported by the battery. This reduces main drive operating hours.
Use different operating modes and maximise the economic benefit
In a two-engine system cross-over mode, both drivelines are operated in different modes. While one driveline is in diesel mode, the electric motor operates as an alternator and provides the electrical energy for the ship. In the second driveline, the main diesel engine is disengaged so that the e-engine receives its energy from the first diesel engine. It operates in motor mode and thus provides the drive energy.
Always ready for operation thanks to guaranteed power supply from the battery
In comfortable hotel mode, power is supplied by the battery alone while the diesel engines are switched off. The innovative technology ensures that power consumption is possible for an extended period without diesel engines. Independently of this, the batteries can be charged in parallel via a charging connection.
Maximum power thanks to the interaction of combustion engines and battery-powered electric motors
Here, the combustion and battery-powered electric motors work hand-in-hand and complement each other. When power is needed, the electric motor provides additional energy from its power reserves. Thus, the boost mode offers the highest power density and enables maximum power. Working together, the 12-cylinder diesel engine and the e-drive can thus achieve performance equivalent to that of a pure 16-cylinder engine.
Full speed ahead plus charge power for the battery at the same time
In classic diesel mode, the energy for the drive is provided by the conventional diesel engine, or diesel engines in multi-engine systems. In this mode, the electric motor rotates along without function and without generating electricity. In addition, electricity can be generated in diesel mode to charge the batteries. In this case, the operating hours of the gensets are reduced.
