Does anyone have a source for this that isn't the press release? I'm struggling to find something more technical. The video talks about 95% efficiency but the press release says 90%.
Their website doesn't seem to have any real information either, just links to 2011 papers and a note that they work on wireless power transfer.
I assume there's more information somewhere, but I'm completely failing to find it. It's a shame it's not more common to at least link to in press releases (or on the video description).
- iam-TJ 11y agoSame here, but I did figure out that the technology is a development of the existing 'Plugless' [0] by Evatran Group, Inc., and found an Idaho N.L. report dated 2014 [1] "Test Results of the PLUGLESS™ Inductive Charging System from Evatran Group, Inc." which says: "... Note that the maximum efficiency for this operation condition of a 100-mm gap at 3.3 kW is 88.8% at X = −90 mm and Y = −30 mm ..." Which seems to indicate they've improved the efficiency for the heavy-duty system that Evatran, Oak Ridge, Clemson and partners are reporting on now. Then I found [2] "Wireless Charging of Electric Vehicles" which is a July 2015 Oak Ridge N.L. project update that talks about Milestones and the Technical Accomplishments. That search of energy.gov led me to another related project [3] "Technology Requirements and Evaluations for High Power Applications of Wireless Power Transfer" (on-going research into 100kW+). And this [4] "High Efficiency, Low EMI and Positioning Tolerant Wireless Charging of EVs".
