VW’s US Innovation Hub just announced four breakthroughs in electric mobility and sustainable transport. First, the team used artificial intelligence on University of Tennessee’s high-performance computer cluster to develop a modular structure in the shape of tiny pyramids; the structure can be 3D-printed from liquid resins and can hold 30K times its own 0.15 lb weight (68g), so this frame would be up to 60% lighter than the steel frame.
Second, they have developed a method of using paper as a recyclable alternative to plastic parts and foils for EV interiors.
Third, researchers re-created the tail gate of a 2020 Volkswagen Atlas using sheet molding compound, a type of fiberglass-reinforced plastic. The new tailgate is 13 pounds lighter than the metal one, resulting in a weight savings of more than 35%. VW says that the tailgate doesn’t need changes in assembly processes, so it can be produced in high volumes.
Finally, VW’s team has patented a coil and charging pad design with silicon-carbide materials. The research team has been able to increase the charging power level up to 120 kW with this prototype from an earlier 6.6 kW prototype, and their goal is to reach 300 kW.

PSR Analysis: So why is this all important? Apart from the unique savings in weight, the reduction of plastics use and the wireless charging, this is a very good example of how automakers are seeking to further improve their offerings within the electric vehicle world. Constant improvement and innovation (in things like regenerative braking and battery technology) shows a strong commitment to BEV and de-carbonization. PSR
