Regen Braking Calculation?

[BrianG]

Well, you know that brakes work by shorting the motor phases in pulses. When the motor isn't spinning fast, or you brake gently, it will still slow the vehicle down but there isn't enough induced voltage to overcome the reduced braking efficiency and exceed the battery voltage, so no "charging" occurs. When this happens I believe the motor and ESC just absorbs the energy. At least this is how I think it works.
