There are a few _very_ simple chargers at EV Technical Files.

I would personally only use the "Bonn Charger". To me, bad-boy charging is a rather dodgy affair and I would want to have as many safeties in it as possible.

Also, I think you could change the output voltage by adding a variac or transformer to the input (before the GFCI). Eventually your output voltage will decrease to the point where very little/no current will move between charger and battery pack.

To my mind, these particular circuits are very much sub-optimal for use in actual electric cars, but seem like a legitimate jumping-off point for adding additional controls and stuff to make a pretty acceptable charger.
In theory, theory and practice are the same. In practice, they aren't.
