A 'smart' alternator, by my definition is one that ramps up during overrun, ramps up to max under braking and puts out no current at all under normal operation (unless of course a load is applied). My Fiat has such a beast and by charging the battery when parked, I essentially have an alternator kill switch that still does regen. Sadly, while it's a common feature nowadays, it's still not universal (my newer Renault doesn't have one).
