On the 3.6's the alternator output is controlled by the PCM.
There is a table in the software for it.
Output is regulated versus battery temp not ambient temp.
As the battery gets hotter, charge voltage is lowered...

If your in doubt put a volt meter ( or OBD reader ) on it and go for a long drive - you'll see the voltage never falls below 14ish ....
