A motor that is being turned becomes a generator, this much we know. The e-Golf makes use of that for regenerative braking and for recharging the battery when you're in D1-B modes, but what happens in straight up D mode? When you lift off the accelerator, the power needle sits at zero but you're still moving along, so where is that generated energy going?
Is there a clutch that disconnects the wheels from the motor, so nothing is being generated?
Is energy being generated but dumped into a big resistor?
Does the DC-DC converter include a dummy load resistor and that's one of the reasons it's water cooled?
What ever the mechanism, it must have to happen when the battery is full too regardless of the mode setting...
Does anyone know how it works?
