The big problem:
Technically you can connect your Tesla to a standard 110v plug receptacle with the free adapter that comes with the car. But you can only charge slowlyat about 3 miles of range per hour parked. ... It will take up to 4 full days to fully recharge an empty Tesla car battery using a regular wall outlet.
Nightly Charge Time 1 hour 45 minutes
Range per Hour of Charge 29 miles
Power Level to Vehicle
50 amp circuit breaker 40 amp load
I understand what you are saying.
I believe that Japaneese engineers in a gasoline challenged nation will solve the problems if they deem it economically feasable.
