The fifth training unit focuses on hybrid electric vehicles (HEVs). After an introduction with a short glance at the history of hybrid electric vehicles, the training focusses on the different hybrid architectures with their corresponding efficiencies, on the selection of the feasible internal combustion engine (ice) and e-motors. A special focus is given on the operating strategies including stop&go, recuperation, load shifting and boosting. Some benchmark vehicles are selected and presented.
This element provides an introduction to hybrid nomenclature, classification and architectures including efficiency considerations. It explains series, parallel and mixed/power split layouts and discusses the necessary clutches and transmission solutions. Further, the training focusses on power dimensioning and cost comparison.
