The simple solution will be to implement bi directional charging and then use the family car to load balance the grid. Charge at night when power is cheapest and run the house off the car batteries if the price goes up because the grid is running low or just because you can. Not much more to say here. It is just like a computer cashing memory and disk space. Add a bit of solar to some of these homes and you dependence on the grid becomes minor. In this sophisticated tech world this concern was so nothing other than a business opportunity. 
With solar your own home becomes a type of hybrid house. Now who is not a fan of a good hybrid?  Out here in Kansas you can even buy houses with their own natural gas well. Imagine the possibilities. 

Not sure how that is going to work though, the range is already a problem in EV, how much juice can you take out of it to power a house?

and when you grab your car to go somewhere you may find yourself you can't go where you wanted to go because you don't have enough battery?

and it's not like a ICE that you can charge in 5 minutes and you are good to go again with full range.

Also the family car may not be at home to power the house when you want it which is during the day.

And if EVs become mainstream many people can't hook up the car to their grid because they live in apartments/buildings.

So IMO I'm not sure the real world practical application of that is significant to make an impact on the problem Smiley
