You can let Regen go all the way down to zero, in which case the motor will sometimes draw a bit of power if the deceleration is very slow. This is because the motor is acting as a brake to slow down the vehicle. If deceleration is slow, then the power recovered is less than the power needed to feed the stator and the result is a small power loss.

Allows full control with only one pedal (which is quite nice!)

On the other end you can start reducing Regen as the speed goes below a certain point, which should then allow you to safely switch pedals (say 5MPH).

My system is a hybrid. If I am slowly decelerating it will start to reduce at 7MPH so that I can either use the brake or coast till stop. Useful in stop-go traffic.

If I start to press the brake before this speed ramp, the controller commands regeneration until the car is stopped or I release the brake. If the brake is then reapplied below 7MPH it has no effect, only the mechanical brakes are used.

The Regen itself is a bit more complex that what it would seem at first glance
