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 explains which internal combustion engines (ice) might be used for a hybrid powertrain and which ices are mainly used for hybrid drives and why. The training provides a deeper insight into the power dimensioning of the ice engine and the resulting consequences. Combination with e-motors are also discussed. Further, it provides insights in current trends of hybrid vehicles.
