I got the figure of 3 Teslas from a presentation by someone involved in city planning. Unfortunately I don't have the source so I am walking back that statement. However the assumption was level 2 which my understanding is up to 80 amps. I do not have the expertise to speak to how that would impact the local supply.
"500 miles a day" in an EV? Unless you have ready access to superchargers good luck with that. Realistically the range is much less. I never understood the term "range anxiety" until my father bought an EV. And he'd still have to borrow one of our vehicles if he ever wanted to go out of town. And run the heater in winter? Ha! Bundle up kiddo, it's gonna be a cold drive.
The Level 2 charger for the Tesla is 48 amps, but remember that's at 240V. That's only the voltage from the transformer on the pole to your house. Neighborhood service is usually 15kV-30kV. So the draw on the neighborhood's lines is only 400 - 800 milliamps. Depending on the wire used in the neighborhood (AAC, ACAR, etc.) they should be able to handle between 800 - 1500 amps per wire.
Good information. Thanks.
