One place that you might want to limit charge draw, is surprisingly, on 110V. Now most outlets are fused at either 15 or 20 amps, but long term draw should be limited to 12 amps.
In the case of the Volt, GM discovered that a lot of outlets can't actually cope at 12 amps, and would overheat. So they lowered the default to 8 amps on 110, with a menu option for the rated 12 (that you had to activate every time you charged)
Looking at the SAE spec, there is a signal from the charger that tells the car how much current it can supply, so for level 2 charging there is likely no reason to not have the default at 32.
One thing I did notice, is that there is no obvious way on the golf to tell how much power the charger is actually providing, or what voltage line its hooked to. (208 vs 240, 16 vs 30 amps, etc). Yes it gives a time to finish charging, but no way of telling how fast a charger you found.
There are a bunch of 16 amp level 2's out there from the days when 3kw onboard chargers were the norm. I would like to know if I encounter one of these, I might pick another. (and the same with level 3 chargers, they have a factor of 8 in their range of power outputs, anywhere from 12.5kw to 100kw)
I suppose sometime when Sue isn't around to watch, I will wire up a sensor behind the socket, and have it send bluetooth to my phone. (or do it on the day I fit a light to the flap, a mod she would be comfortable with). I wonder if it is something you can find via the ODB port.
