Here are some very rough guess charging times for L1 (120Vac) and L2 (240Vac) ID.4 charging, given the 77 kWh (energy) rating of our ID.4 battery.
You can see why so many are saying that 32A charging (7.6kW) will be okay for most. From 7.6kW (32A) to 11kW (48A), 240Vac charging from "empty" varies from about 10 hours to about 7.5 hours. For those few who only have 8 hours of charging time and need a full charge every day (probably a rare use case), 11 kW charging is the way to go. (charging rate is power in "kW" (kilo Watts), energy added is in "kWh" (kilo Watt hours))
This chart also shows the problem with the OEM supplied charger (assuming 12A / 120Vac), where empty to full takes about 55 hours (more than two days!). Also, with an adapter (if that can be done with the VW OEM EVSE), even at 240Vac, it would still take about 26 hours to go from empty to full (which might be fine in some cases).
