Just wondering which method of slowing down provides better regen. If you're going 45 mph with a stop sign coming up, does it provide better energy recovery if you start to slow from far away and gradually come to a stop, or if you continue at 45 mph and fully release the power pedal (ignoring the whiplash) at the last minute, or is there no difference from the regen perspective? In both cases, the energy from 45 to 0 mph is partially recaptured and partially dissipated as heat. Is the regen more efficient at higher or lower rates?
