> Driving the car is constantly charging / discharging it (regen braking). My understanding is that the impact on battery longevity relates to the rate at which it is being charged/discharged. Accelerating and regenerative braking are small potatoes compared to charging over a typical level 2 system, I would think. |

A typical L2 charger will provide in the range of 6-10kW (AC, marginally less ends up going to the battery after conversion losses). 10kW is only 13hp; forget acceleration - the car draws more than that at highway speeds.
(You can come at this result another way too - an L2 charge may take 6-10hr to refill the battery from empty. But the car would not be able to drive 6-10hr at highway speed starting at 100% charge! So the L2 must be delivering less power than the car consumes at cruising speed.)
