General ESC Theory Discussion

[BrianG]

Well, if the vehicle were moving fast enough (high motor rpms) and then you brake hard allowing the field to collapse very quickly, the induced back EMF could be greater than the battery voltage.

Perhaps, but that possibility could only last for a split second then - the time taken for the ESC to stop supplying power to the windings. It would be ideal if as much of the car's kinetic energy transfered during braking as possible could be converted back into electrical energy that charged the pack...
