You're right, of course.

I just wonder if any smart chargers are smart enough to know, when
charging power is restored, and they find the battery at X%, whether the
battery is at X% because the charger was in the middle of a particular
charging profile five minutes ago when the engine was turned off to run
into the sandwich shop.  Or is it at X% because the van has been parked
for a week after the charger finished a later step in the charging profile.

And whether, with that little bit of memory, the charger can do an even
smarter, better job of preserving the battery's life and capacity.
