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.
The element explains and gives insights into the possible operating strategies and the attached energy management of hybrid vehicles. It describes the modes stop&go, energy recuperation, load shifting, boosting and charging and explains their benefits as well as their limiting factors.
