Volkswagen Group of America reveals analysis breakthroughs to extend EV vary and recycle automobile supplies Receive US

Volkswagen Group of America, Inc. (VWGoA) is boosting its automotive analysis in america to additional speed up electrical mobility and sustainable transportation innovation. The corporate continues to middle strategic areas of analysis in devoted expertise models throughout the nation, in addition to foster co-innovation with universities and federal analysis services.

One key unit is situated in Tennessee: Volkswagen’s Innovation Hub in Knoxville is driving utilized supplies science in collaboration with the College of Tennessee (UT) and Oakridge Nationwide Lab (ORNL). There, built-in groups are pushing breakthroughs in automotive light-weight composites, recyclable inside supplies, and EV wi-fi charging.

“We’re accelerating innovation inside electrical automobiles and contributing to extra sustainable transportation in America by focusing our efforts on a number of the most transformative automotive analysis being carried out within the nation,” stated Pablo Di Si, President and CEO at Volkswagen Group of America Inc. “Our expertise groups in Tennessee are an awesome instance. There, we’re tapping American ingenuity fostered by the distinctive mix of world-class educational analysis and Volkswagen’s main {industry} capabilities.”

Opened in 2020, Volkswagen’s Innovation Hub is situated on the College of Tennessee Analysis Park at Cherokee Farm in Knoxville, in a area known as ‘the Supplies Valley’ because of the focus of analysis services. This consists of the ORNL, of which VWGoA has additionally established analysis collaborations. Volkswagen researchers, UT college and doctoral college students in addition to ORNL scientists collectively drive analysis and co-innovation of utilized supplies analysis.

“Centering extra data in america is a part of Volkswagen’s technique for progress and is important for sourcing and creating expertise,” Di Si added.

“The Volkswagen Innovation Hub is a robust instance of the type of scientific advances and industry-ready expertise that you would be able to carry to market if you find scientists and researchers from throughout disciplines and organizations collectively in a single place.”, stated UT Chancellor Donde Plowman.  “With companions like Volkswagen, Oak Ridge Nationwide Lab, and others {industry} leaders and tech startups situated at UT’s Analysis Park, we have now created a thriving innovation ecosystem.”

The Innovation Hub groups lead analysis within the following key initiatives:

AI-optimized materials constructions to extend electrical automobile vary

Volkswagen researchers are engaged on new materials constructions to cut back automobile weight, which helps to extend the vary of electrical automobiles (EVs). As a primary pilot, the staff has chosen the metal body that homes the EV battery pack within the automobile and shields it from bodily impacts.


By operating a deep studying algorithm (simplified: synthetic intelligence) with as much as hundreds of thousands of parameters on UT’s excessive efficiency compute cluster, the staff has developed a modular repeating construction in shapes of tiny pyramids. This construction might be 3D-printed from liquid resins and holds 30,000 occasions its personal 0.15lbs-weight (68g). A newly created body can be as much as 60 p.c lighter. Hardcore sturdiness checks confirmed that it exceeds the traditional metal body in vitality absorption, and will function a light-weight, but ultra-robust different.

Paper-based supplies for automobile inside design

The hub staff at UT’s Heart for Renewable Carbon is creating recyclable alternate options to plastic elements and foils within the automobile inside. Their focus: paper. The staff has patented a technique of preforming and hot-pressing cellulose fiber strengthened thermoplastics into the sturdy inside elements clients anticipate.

These paper-based composites should not solely recyclable, they will also be remodeled into numerous inside sizes and styles, together with backlit and ambient mild choices. The staff has additionally innovated methods so as to add completely different textures and colours, so automobile inside designers take pleasure in flexibility and inventive freedom.

The Volkswagen model is already checking alternatives to incorporate these paper-based inside elements in future mannequin traces and work to assist industry-scale manufacturing.

New fiber composites for light-weight automobile elements

The Volkswagen staff kicked off light-weight supplies analysis with UT by recreating the raise gate of a MY2020 Volkswagen Atlas utilizing sheet molding compound (SMC), a kind of fiberglass strengthened plastic. The brand new raise gate proved to be 13 kilos lighter than the traditional metal-based model; a weight-savings of greater than 35 p.c, which may assist to extend the vary of electrical automobiles and people powered with a combustion engine. As well as, the choice composite raise gate doesn’t want adjustments in meeting sequence in comparison with standard variations – that means these elements are match for top volumes.

The staff’s analysis breakthrough has already discovered its method into automobile manufacturing. Bentley and Lamborghini have adopted these new supplies and the molding course of for the Bentley Continental, and within the Lamborghini Aventador. The staff in Knoxville has additionally began a analysis challenge to discover light-weight choices for pickup beds and rugged elements.

Extra not too long ago, Volkswagen and UT researchers have additional refined molding processes and methods to optimize sturdiness, high quality and design choices. One particular take is to optimize the fiber-matrix-interface, a course of known as “sizing” – basically creating the smoothest, most sturdy coat for fibers doable.

New high-power wi-fi EV charging ideas

Volkswagen’s staff has patented a singular coil and charging pad design with silicon-carbide supplies to optimize charging velocity and security. Their purpose: Assist make charging an electrical automobile as simple and cozy as pulling into a standard storage spot.

Within the first early trials with a silicon-carbide inverter, this prototype system has proven excessive effectivity. Utilizing Volkswagen’s experience in automobile energy electronics, ORNL’s capabilities in excessive energy wi-fi charging, and UT’s data of energy electronics optimization, the analysis staff has been in a position to enhance the charging energy stage as much as 120 kW with this prototype from an earlier 6.6kW prototype, with a future purpose of 300 kW.

Volkswagen’s Innovation Hub Knoxville is contributing to the worldwide Volkswagen Group’s bigger innovation ecosystem, together with innovation facilities in Belmont, California; Wolfsburg, Germany; and Beijing, together with hubs in Singapore, Tel Aviv and Tokyo.
