A Tesla car battery can store as much electricity as my house needs in 10 days. That would see it through many a sunless and windless night.
It is entirely possible, but admittedly quite expensive.

Then it would be stupid to have every house equipped with big batteries. There's a grid, and the wider it cooperates the lesser the variations will be - not zero, absolutely not; but much less than local.
Strategically placed units on the grid can be cheaper, smaller in total and much more effective. They could f.i. also help improve the electric phase integrity.
Many EVs will be hooked up to the grid at any one time. They can be charged 'smart' when beyond a certain minimal level or even provide a buffer to optimize supply and demand.
