I did some calculations on how much more renewable the UK would need based on demand over a given year, and how much storage. With 20 times the current renewable, 1GWh of charged storage, and a perfect grid, starting on Sep 18th 2018, we'd be fine until September 30th at 18:15. With 10 million EVs acting as a battery store, all topping at 50KWh and going as low down as say 25KWh, that would be 250GWh of storage, we'd last until September 30th at 19:30. That doesn't count the extra demand of the EVs in actually driving. If we had 50 times current renewable and that 250GW of storage we'd be OK.
