Why couldn't it be shunted off to a big chunk-'o-wire and a heat sink?

On a PT, there may be a way to add braking circuits externally. I know it's a bit of a reach. I still haven't done anything about it but think. I was thinking that there may be a way to make the augmented braking system with a few less brains by having the variable load proportional to it's own revolution rate, instead of trying to sense the current going to the PTs battery packs. By adding this ("HBS"-type) accessory brake, it allows for additional EMF braking without putting further strain on the motors. After all, one of the limiting factors in regenerative braking is the peak power limit of the motor's windings. |

I was absolutely referring to the EV portion of the quote since the PT part of it doesn't really require any more of an energy sink than it already has.
citivolus had been talking about an energy sink for use during panic stops.

Yeah, sorry about that. Now I see.

That said, Karl's idea of charging the body shell does sound like it could have some rather "hair raising" applications.
