Aren't those designed to regulate the output of an alternator by adjusting its field current? That would take some effort to adapt to a charger, methinks. Or maybe I don't know what I'm talking about, and automotive voltage regulators have changed. Even at that, they might expect to chat with the ECU. If so, you'd have to rig a way to control them. For example, I had a 1995 Civic VX, and even though its control was less complex than today's cars, the computer was pretty smart about SLI battery charging. IIRC, it would tell the alternator and/or regulator, "Charge the battery hard when the car is decelerating. When we go into lean-burn high MPG cruise, don't charge it at all, unless you have to."
