Another point driving EV adoption is the grid factor. You can program most EVs to charge at a given time (like late night when rates are lower) so you plug it in and go in the house, it will charge when you told it to (this comes in to play later). Some, like the F-150, are already set up (if you have the right equipment installed) to power your house if there is a power outage. But it goes beyond this. GM and PG&E and others are working on vehicle-to-grid. In this model, if the grid is getting close to capacity or having other problems, those who have opted into the program will have the capability to let the grid draw from their plugged in cars. The meter will run backwards (thus paying for the energy the grid pulls from the car battery) and the grid gets the extra safety net of additional power storage to draw upon. The grid can be set to draw no more than 50% or whatever you prefer from the car. And of course, if you do not want to contribute you don't have to sign up (it's not automatic).
