The eTrailer replaces one of the free-wheeling axles with an electrified axle. This powerful electric axle of the eTrailer supports the semitrailer tractor system along the entire route, in normal driving operation, when starting and when tackling inclines. The electric driveline helps recover energy (recuperation) during braking. If not all the electrical resources are needed for the above tasks, the electric drive of the eTrailer permanently supports the diesel drive of the tractor unit over the entire route with the remaining energy.In combination with a battery-electric tractor unit, the eTrailer brings about a significant increase in range.
The modular battery capacity enables a technically and economically reasonable mapping of individual logistics scenarios. The traction batteries are built in lithium iron phosphate technology, which ensures a high cycle stability and low flammability and are therefore particularly suitable for intensive use in heavy goods transport.
The sensor-based real-time control of the eTrailer ensures transmission of the forces at the kingpin to the VCU (Vehicle Control Unit) and thus safe control of the electric drive axle.
With the Trailer Dynamics efficiency software PDC "Predictive Drivetrain Control", the electrical energy resources can be intelligently and optimally managed along the entire route. The cloud-based system supports real-time control of the vehicle's electric powertrain and provides a sophisticated driving strategy tailored to the requirements of the route. To accomplish this task, the PDC incorporates all vehicle system parameters, weather data, traffic data, topography and more into the optimization calculation. In conjunction with the Trailer Dynamics PDC, the electric powertrain can be used in the most economical way.
