Volkswagen said today it has patented a unique coil and charging pad design with silicon-carbide materials to optimize charging speed and safety. The object is to make charging an electric vehicle as easy as pulling into a parking place. In the first early trials with what is called a silicon-carbide inverter, the prototype system has shown high efficiency. A research team* has been able to increase the charging power level up to 120 kW with this prototype from an earlier 6.6kW prototype, with a future goal of 300 kW.
“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.
“Our technology teams in Tennessee are a great example. There, we are tapping American ingenuity fostered by the unique blend of world-class academic research and Volkswagen’s leading industry capabilities,” said DiSi.
Volkswagen’s Innovation Hub Knoxville, opened in 2020, is part of Volkswagen Group’s innovation centers in Belmont, California; Wolfsburg, Germany; and Beijing, along with hubs in Singapore, Tel Aviv and Tokyo. It is located at the University of Tennessee Research Park at Cherokee Farm in Knoxville. This includes the Oakridge National Lab (ORNL), where VWGoA says it has also established research collaborations. Volkswagen researchers, UT faculty and doctoral students as well as ORNL scientists collectively work on technology projects.
*The research team is “using Volkswagen’s expertise in vehicle power electronics, ORNL’s capabilities in high power wireless charging, and UT’s knowledge of power electronics optimization,” VW said. AutoInformed notes that prototypes are not necessary production possible or ready.
About Ken Zino
Ken Zino, editor and publisher of AutoInformed, is a versatile auto industry participant with global experience spanning decades in print and broadcast journalism, as well as social media. He has automobile testing, marketing, public relations and communications experience. He is past president of The International Motor Press Assn, the Detroit Press Club, founding member and first President of the Automotive Press Assn. He is a member of APA, IMPA and the Midwest Automotive Press Assn.
He also brings an historical perspective while citing their contemporary relevance of the work of legendary auto writers such as Ken Purdy, Jim Dunne or Jerry Flint, or writers such as Red Smith, Mark Twain, Thomas Jefferson – all to bring perspective to a chaotic automotive universe.
Above all, decades after he first drove a car, Zino still revels in the sound of the exhaust as the throttle is blipped during a downshift and the driver’s rush that occurs when the entry, apex and exit points of a turn are smoothly and swiftly crossed. It’s the beginning of a perfect lap.
AutoInformed has an editorial philosophy that loves transportation machines of all kinds while promoting critical thinking about the future use of cars and trucks.
Zino builds AutoInformed from his background in automotive journalism starting at Hearst Publishing in New York City on Motor and MotorTech Magazines and car testing where he reviewed hundreds of vehicles in his decade-long stint as the Detroit Bureau Chief of Road & Track magazine. Zino has also worked in Europe, and Asia – now the largest automotive market in the world with China at its center.
