Potentiale und mögliche Anwendung mechanischer Energierekuperationssysteme im Kfz

InhaltsangabeA hybrid system comprises a co-operation of two different propulsion units in one vehicle.
Usually this term is used for a combination of an internal combustion engine with one or more electric machines. The storage of electric energy in the vehicle needs accumulators. The downside is that these accumulators are very expensive and quite heavy.
These two aspects were the motivation to work out the potentials of mechanical energy
recuperation systems (MERS). For this reason the function of an electric hybrid system is
substituted by mechanical energy recuperation systems and the potential of these systems is determined.
Firstly a benchmark vehicle has been defined. The vehicle has been chosen due to its
availability with an electric hybrid drive train and also with a conventional drive train with a
gasoline engine.
Mathematic models of the mechanical energy recuperation systems have been created.
Standardized driving cycles have been used to compare and dimension the main components of the different systems. Two systems have been worked out in detail, one with a flywheel and one with a hydraulic storage system.
