Which are obligatory for the fast charging of lithium batteries but I
have never seen one for a lead acid.

They are used on the trolley mounted fast chargers you'll see in a
secondhand car dealer's lot. But never seen a domestic car battery charger
with one. A large domestic charger might have a peak output of 15 amps or
so, and no need for a sensor at that sort of current, which will regulate
down as the battery charges anyway.

Wonder how a 150 amp car alternator gets away without sensing battery
temperature? ;-)

I suspect for a battery in an air flow its not so critical. What I have
noticed is charging voltage as per my instrument cluster reduces
alternator voltage on a hot day. I wonder if the alternator has an air
temperature sensor.
