An alternator generates AC current, whereas batteries (as far as I know) provide/are charged with DC current. So I'm wondering, how is this apparent mismatch explained? Do car manufacturers employ a rectifier downstream the alternator in order to convert AC to DC? Wouldn't it be simpler to use a dynamo instead, to directly generate DC current? Also considering that, when present, regenerative braking systems provide DC power (so are they connected to the battery pack via a different power transmission line?).
P.S. I apologize in advance if the question does not meet some community requirements, I am new to Stack Overflow, plus it regards a discipline I am still trying to learn about.
