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? ;-)

It doesn't. Voltage regulation means the charge tapers off. This is why
it takes a ridiculous length of time to fully charge a car battery.
