ELVIIS Smartgrid V2G System

You probably heard about this suedish system called ELVIIS; I think it is pretty nice and I have been thinking about this for the last wears: Going to work, Plugging in, Charging, Giving back some power to the grid when demand is high to avoid pics (lunch hour), charging again if necessary in the afternoon for the trip back home ...
ELVIIS is doing all this and is also taking into account the production of electricity available in the grid from wind & solar
It's all gonna work like this one day I was thinking, and these people took a big step forward
Take a look at what they did

Nissan e-NV200 - Great Electric Mini Van

Think Big 
This mini van is going to be a big hit I think, like the LEAF. Based on the same powertrain and battery pack,  it's a perfect fit for large families or people who need a lot of storage capacity, taxis, contractors, etc

Smartgrid ready !
In the 2nd video below, you will see that the NV200, like the LEAF, could be used as a source of energy, to power the house when power demand is high, in the evening, and then will charge at night when power demand is low
