Volkswagen Group Uses Tennessee Lab To Add Lightness, Improve Wireless Charging
Volkswagen Groups Innovation Hub in Knoxville, Tennessee, is working on a number of ways to make electric cars more efficient.Anthony Colin Bruce Chapman, founder of Lotus Cars in 1952, had a favorite expression — “Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere.” Chapman was famous for subtracting weight, often to the point of failure.
“We are accelerating innovation within electric vehicles and contributing to more sustainable transportation in America by focusing our efforts on some of the most transformative automotive research being done in the country,” said Pablo Di Si, President and CEO at Volkswagen Group of America, in a. “Our technology teams in Tennessee are a great example.
Using artificial intelligence to run a deep learning algorithm with up to 10 million parameters on the University of Tennessee’s high performance computer cluster, the team developed a modular repeating structure that uses tiny pyramids. This structure can be 3D-printed from liquid resins and holds 30,000 times its own weight. A newly created frame is up to 60% lighter, which is some serious weight reduction.
Now you are talking about a vehicle that is hundreds of pounds lighter. Less weight means smaller brakes and less beefy suspension components, which adds up to even more weight reductions. Better yet, the composite lift-gate does not need changes in assembly sequence, which means no expensive refitting of the factory in order to use it in actual production at high volumes.
