I was looking at 210.17 for electric vehicles, and it doesn't say what voltage or amperage this needs to be. Does anyone know what they will require?

Also 210.52 G (1) says garages will need 1 receptacle for each car space. Can these be the receptacles that supply the garage door openers? I don't see anything that says it must be readily accessible

IMO it is the dumbest rule as many chargers are 240V and more than 20 amps. As far as I know a standard 120v recep. is all that is needed.
 
A level 1 charger is rated 120 V, 16 amps, continuous. Charge may take up to 8 hours, think of it as jumper cables
Level 2 is 240 V, 32 amps so a 40 amp branch circuit, this is what most EV owners will have.
Level 3 is a DC fast charger, maybe 400 volts, fed from 480 3 phase. I have attached a picture of a level 3 charger. Very expensive, but will charge up your EV in about 30 minutes
Take a look at 210.20 B 1

Well since I guess it's up to us to put wherever we want in, what are you going to do?
I'm not going to charge my builders any more money for this so I guess I'll just throw in a 120v 20 amp gfi. At least this way I'm not putting in 240v 40 amp circuits for the 1 in 10 people that actually have an electric car, and may in turn generating work for myself down the road if they need it upgraded.
