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 introduces a variety of hybrid electric vehicles (HEVs) and Plug-In HEVs (PHEVs) which were and are currently on the market and can be regarded as benchmark examples. This section shall provide an overview on interesting vehicles and give insights into their technology and design philosophy.
