If regenative braking adds X charge to batteries, then afterwards speeding back to original speed will take more than X energy.
Regenerative energy is much more efficient than normal braking; but in any case it's far more efficient to simply stay at the same speed. Stop & go is extremely inefficient with normal brakes, and just inefficient with regenerative brakes.
