Investigation of Electrified Trailer Axles by Use of a Functional Model

Excerpt

Electrification makes its way into the heavy commercial vehicle sector. High moving masses offer a big potential for recuperation and therefore for an increase of the total efficiency. The system developed by SAF-Holland and the Institute of Mobile Machines and Commercial Vehicles at Technische Universität Braunschweig shows that electric systems can be used sensibly not only in the truck but also in the trailer. An electrified trailer axle generates electrical energy during braking, which can be temporarily stored and used for auxiliary consumers or for traction support later. A simulation model is used to optimize the control strategies and to estimate saving potentials. Test drives are carried out with a functional model, the first results of which are presented. …
