With US research, VW wants to wirelessly charge a Porsche Taycan to 80% in 10 minutes
Volkswagen Group of America is starting a joint research project with the Oak Ridge National Laboratory (ORNL) of the Department of Energy and the University of Tennessee, Knoxville to develop wireless charging for electric cars.
With a Porsche Taycan as a test bench, teams from VW, ORNL and UT Knoxville have increased the power of the wireless charging hardware from 6.6 kilowatts to 120 kW, according to a VW press release. The goal is to reach 300 kw, which would be enough to charge the Taycan to 80% in 10 minutes, the automaker said.
The researchers want to get a better picture of the potential hurdles to high-performance wireless uploading, but VW hasn’t mentioned any specific plans to commercialize this research in the near future.
The project will build on previous research on wireless charging at the ORNL. In 2018, the researchers announced an excellent efficiency of 97% for the technology at up to 120 kw without any losses in power supply.
Volkswagen, Oak Ridge National Laboratory, and UT Knoxville are testing wireless charging
Some companies offer commercial wireless charging systems, but the technology has a long way to go before mass adoption. So far there has been a single standard for cross-compatibility, but it only extends up to 11 kw. High-power charging is new territory.
Momentum Dynamics has a system that is already being tested on Jaguar I-Pace taxis in Oslo, Norway and is capable of charging up to 50 kW in bursts of 6-8 minutes.
Among the automakers, BMW has tested wireless charging with its 5-series plug-in hybrid, but has not yet published any results from this test. And the Genesis GV60 could be the first electric vehicle to offer wireless charging of original devices on a large scale.
