A major part of the energy generated in an internal combustion engine is not realised as work output, but sent into the
atmosphere as waste heat. The overall efficiency of an engine can be improved by tapping this waste heat and converting
it into usable energy. There is a potential for recovering approximately 30-40% of the energy supplied of the energy,
depending on engine load. Thermoelectric Generators (TEGs) have been receiving a lot of attention for their promise in
efficient conversion of the waste energy into electrical energy. The efficiency in employing TEGs for battery charging
under different drive conditions needs to be analysed before deploying them on the vehicle.
In this project, a waste energy recovery system employing TEGs for charging the battery is modelled, simulated and
analysed from a systems point of view. A drive cycle test was carried out on the target vehicle to map and characterize the
temperature profile of the exhaust system to identify design characteristics of TEG systems and its co-systems, including
their optimal placement. Since the output voltage o
