True. At least it's not entirely in the "100 mpg carburetor" category like so many of the claims regarding EVs are.Seems like a lot of confusion in the reporting. From what I can gather, Toyota is reducing the losses in the power electronics by 90%. The 90% would, however, be a relative not an absolute reduction. For example, if the power electronics lost 1% of the battery power in the form of heat currently, the new conductor would have it only lose .1%. A 1% gain is great but it's not a 10% gain in overall efficiency.
Or something. Very hard to tell what is happening from the article.
