When the power gauge needle swings over to full charge (green /left side on analog dash), the car is using friction. I do not know how to see this via OBD. FYI there is always energy loss even when using regen - 2nd law of thermodynamics means you lose energy through heat generated in copper wiring, power electronics, motor, gearbox, tires, etc.

Right. I was thinking about friction braking from high speeds. For low speeds, you are correct that the friction brakes engage at ~5 mph or less to bring the car to a full stop and the power needle is certainly not pegged at full charge. I have noticed it seems to be the rear brakes that bring the car to a stop at slow speeds.
