A 240V 20amp circuit I think would meet the needs of 99% of commuters in the US. If your average miles/kWh is around 3.3 and you’re charging at 80% of the 20amp breaker limit (as you should be), even factoring in 10% losses in power transmission, you’re still charging somewhere around 11 miles per hour. Easy 100+ miles overnight with zero infrastructure change outside of a couple wire nuts and a cheap charger. Hell, depending on local codes, you might get away with slapping in a nema 6-20 receptacle to make it even easier…

If you do a receptacle, you’ve got to then do a GFCI. Check out the price difference between a GFCI breaker and one that isn’t. If you hardware the EVSE, you don’t need GFCI because GFCI is built into nearly all EVSE. If we’re doing this exercise to keep low costs, adding GFCI outside of the EVSE jacks up the price.

Fair enough! Anyone with existing 240v receptacles of any kind is a lucky duck, regardless.
