How long to fill up an EV?

Geoff Styles on a potential Achilles heel of the electric vehicle (emphasis is mine):

To understand why recharging EVs is such a tough problem, let's take a look at your last visit to the gas pump in terms that would never occur to most people. Gas pumps in the US are limited by EPA regulations to deliver a maximum of 10 gallons per minute. Half that is probably more typical. But even at 5 gallons per minute, the gas pump is "recharging" your car at the power equivalent of 10 megawatts (MW), effectively delivering the entire daily power consumption of the average US household every 12 seconds. Even if you discount that figure by the lower conversion efficiency of an internal combustion engine, it's still the equivalent of a couple of megawatts. Matching that for an EV would require either stupendous voltages or currents well above most designers' comfort level. For example, a car recharger drawing 100 amps would have to operate at 25,000 Volts--more than ten time the voltage of the electric chair--to deliver a comparable charge in the same interval. At the 240 V of your home's appliance circuit, you'd need about 10,000 amps--similar to what a transit train draws from the "third rail." Almost inevitably, the safe recharging of EV batteries must take longer--hours longer--than refueling your gasoline vehicle, or entail clever-but-costly workarounds such as the battery-swapping scheme of Better Place and other firms.

I wouldn't rule out clever workarounds, but this is a legitimate and substantial barrier to EV adoption until one comes around.
