Good! Cheaper, greener, and safer will be huge for the auto industry!

I wonder if that could be used for hybrid with gas or turbo diesel so no charge station needed. Run the "generator" for 15 minutes when low to recharge. Or better yet, if you can't have it charge on the fly, use 2 separate batteries so one charges while the other is used. My old F-150 had 2 gas tanks back in the 90s. Same concept.

Personally this is the best of both worlds to not tax the grid so heavily and so drastically reduce the use of fossil fuels at the same time. You could have a 2-3 gallon tank last 4-5 charging cycles or more for "1,000mi+ per tank of fuel"

I like the way you think, but it's not quite realistic. This 4c charge means 4x the battery capacity (45kwh) in an hour as a charge rate. If my whiskey addled math pencils out, that's something like a 480v at ~100A DC, so, not your average generator. Not exactly a Chevy Volt kind of situation.

But it's approaching something you can charge in a "gas station like stop" with reasonable range.

OK, good to know. So maybe run that generator-like source for a little longer.

Do BEVs still use the car's momentum or braking to recharge the batteries like a lot of hybrids used to or still do? I know it won't amount to much but I'm sure it helps.
