Regen braking: confirmed!

[JERRY2KONE]

AFAIK, a single mechanism (the motor) can't function as a generator and a source of power at the same time. You must use power to brake the car. I'm not an electrical engineer, but I know a few things about physics and the forces that are present and being applied in this scenario simply can't be ignored.

During my 20 years in the Navy I have seen on a couple of occasions where I generator which normally puts out huge amounts of power was turned into a motor when the electrical power flow was reversed accidently. Due to the circuitry involved within the system it was not supposed to happen, but it did.

There is no way that electrical braking is accomplished without using some source of power. That's just a relitive impossibility. But as you stated Patric can probably explain this so we can all understand it.
