What about self-charging EVs? These are the ones that just use regenerative braking to give a boost to MPG. No plug in at all.

That is the only type of EV I would consider. The batteries that support the regenerative braking are small and don't add that much weight to the car. I imagine they are also much less of an explosion hazard.

You can recapture 90 percent of the power normally lost to heat in braking. But you only get back about ten percent of the power you used to achieve the speed you brake from. And, of course, the longer the trip before you brake, the lower that percentage is. I suppose you do get something back, but in the grand scheme it’s a rounding error.

Perpetual motion fantasy. If you think this is a solution God help you.

Pretty sure almost every EV has that capability. It's not anything special - when you slow down, the car is pushing the drive motor so it acts as a generator, and gives back a bit of the energy you put into accelerating. Instead of creating a bit of heat, you generate a tiny bit of power.

And they don't have special batteries, they just feed power back into whatever your main battery is.
