Rapid-charge stations will become fairly common; they can be built more cheaply than gas stations (which, by the way, didn't exist when the Model T was first sold.)
Anticipated objections to EVs causing brownouts have already appeared in comments on Wired, which ran excerpts of this article. In replying, I pointed out that the US DOE said this year that 84% of all vehicles in the US could be powered electrically without having to build a single additional power plant, as long as the vehicles are charged at night.

BillWilliam:

Of course the answer is a battery pack at the charging station to supply the peak load when a car or cars come in for power. We don't fill gas tanks with cans or barrels like was done at the start of the automobile age and it makes sense to have a storage battery for the charging station too. This would be refilled on a 24 hour basis.
I hope Altairnano can get the cost down to a reasonable level so this will work.

THE HOLY GRAIL !!!!!!!

Christopher Watt:

I'm sure when the first Model T rolled off the production line, people were asking the question. "How are we going to supply the energy to power this new mode of transport?" That question has been answered. Now with the alternative to the internal combustion engine providing a new way to propel ourselves, we are asking that same question again. Petrol is trickle fed to gas stations all over, and pumped into underground storage units. I believe this can also be acheived with electricity. With connections already in place, all that is needed is a storage unit to supply customers with electricity during heavy periods.

Maria:

I guess bringing up these sources we are really looking forward for ZAP'a and alike !

Alastair Carnegie:

The obvious solution is to install flywheel batteries, that can be charged up at convenient times. They are now very compact, and half-megawatt flywheel batteries are standard 'off-the-shelf' stock items. Ready for delivery this week, not next year!

A few thousand flywheel batteries could also recover their installation cost, as they would prevent power outage on the grid, utilities pay premium prices for stop-gap power. Peak load is often highly predictable, so EV users could be notified in advance, allowing them to re-schedule their next charge.
