To meet the future development in vehicle drivetrains, the Institute of Vehicle Concepts of the German Aerospace Center (DLR) aims to prove, that exhaust heat recovery using a Thermoelectric Generator (TEG) is, even with more electrification, still a promising concept to increase efficiency. Together with material researches at the Fraunhofer Institute of Physical Measurement Techniques (IPM) in Freiburg, the DLRs next generation of TEG is adapted to the special boundary conditions in hybrid vehicles. After investigating and measuring these boundary conditions, a first potential analysis is made. In test cycles a potential reduction of fuel consumption of about 3 % is calculated. It has been shown, that under exemplary driving conditions the possible electric power output of a TEG can be increased, compared to conventional vehicle, despite the increased efficiency of the drivetrain in a hybrid.
