interesting,
did not know there was a standard for the chargers, as in each car make seems to have a different plug and charger stations,
friend has a tesla, and uses a drop cord at his house, he is near baltimore and has plenty of charging options where he frequets, (but does have to wait to charge if he is not doing something near by, )
his mother installed a tesla station for him at her house, which down in the southern part of the state, and not as many options,
I think he said it was about $7K for the station and installation
