Quo Vadis electric drives? Product innovations for commercial vehicle applications

When it comes to the electrification of the drivetrain, commercial vehicles in particular impose special requirements on the energy storage system and the associated range. Against this background, the installation space requirements, efficiency and performance of the electric motor play an even more important role. With the increasing transformation from conventional to electric drives, numerous innovations in the field of electric motors can be observed. However, due to the different requirements profile compared to passenger cars, not all innovations can be transferred unconditionally to the commercial vehicle sector and their suitability must be examined against the background of the effects, for example, on the installation space requirement, the efficiency of the drivetrain or the performance capacity.
