the alternator current limits when a low impedance load is applied and
acts like a constant current source at about the battery voltage. IF
you apply it to a Lithium Ion cell (or most other chemistry types)
that is fully charged then it will potentially do damage, but until
then it works acceptably.

The alternator is rated at Valt >> Vbat at full revs so that it can
still charge at less than full revs.
