VW To Use Heat Recovery Systems
February 9, 2009 by admin
Volkswagen has shown a prototype vehicle equipped with a thermoelectric generator according to the International Thermoelectric Society website. The system recovers the dissipated heat energy and converts it into electricity. The prototype has been shown at the “Thermoelektrik - Eine Chance Für Die Atomobillindustrie?” meeting held in Berlin in October 2008.
The thermoelectric generator is reportedly able to gain about 600W from a car running on a highway, meeting about 30% of the car’s electrical consumption requirements. For the moment, the thermoelectric generators haven’t been embedded in a hybrid car, although VW says with the current setup it can save about 5% of your fuel consumption.
BMW and DLR (German Aerospace) also competed with Volkswagen by showing a system with a 200W output. They say it has been used for more than 12,000 km. They are both integrating TEGs with future gasoline powertrains. BMW even has them in their plan for the 2010 - 2014 5 Series cars.
