MAN Smart Hybrid Experience

For the development of new, efficient and alternative powertrains an increasing electrification of its components is key focus. MAN Engines as part of MAN Truck & Bus SE is currently developing a marine propulsion solution with incorporated energy management system, that extends the proven diesel technology with an electric machine. Since the MAN Marine Hybrid System for marine applications provides a higher variance than conventional powertrain setups, the individual adaption for expected areas of use and load profiles plays a major role in the optimization process. Non-disruptive changes of operation modes give versatile challenges when developing and calibrating this system. Amongst others the high requirements in comfort and improved performance of the dynamic system behaviour will be described and characterized. Hereby the focus will be on operation mode transitions that could already be measured in the test bench setup. Supported by investigations on the elaborate test bench setup an evaluation of efficiency aspects gives a first impression on the economic prospects of the MAN Marine Hybrid System for the use in commercial as well as pleasure marine applications.
