TORQUE DEMAND is what really sucks up the wattage and power requirement.
If you have little to no torque demand, then the power source wont be pushed too hard.
If you have the ABILITY to stop the vehicle in the fashion of the "red-to-red-tire-smoking-pink-slipping-street-rod-drag-racing"
AND be ABLE to regeneratively brake at the same time, then wouldn't that make sense?
Not only that, but you don't have to mash that brake pedal every time you stop. The regenerative brakes work much like the exciting of the rotor on an alternator: If you barely put any current into the rotor, the output will be very small on the stator, and the horsepower will be minimal to turn it. If you put a ton of current into the rotor, the output of the stator will be very high and result in the large requirement to make it rotate.
This very ability to change the duty cycle of the regenerative braking force is what allows the 'variable braking force' to be applied and NOT use the brake friction surfaces during the stopping motion/ operation of the vehicle.
The ability to capture more power in a more efficient manner is a great thing to have.
