DETROIT

WITH electric cars and plug-in hybrids at last trickling into the showrooms of mainstream automakers, the dream of going gasoline-free is becoming a reality for many drivers. Cars like the Nissan Leaf and the Chevrolet Volt can cover considerable distances under electric power alone — certainly enough for local errands and even most daily commutes — while enabling their owners to shun gas stations.

Indeed, charging the car’s battery pack at home, or topping up at the office or shopping mall, will work fine for most drivers. But what about trips that are beyond the range of a single battery charge? Couldn’t a driver in need simply pull up to a charging kiosk and plug in for a rapid refill?

It’s not that simple.

Sure, there are already public charging stations in service, and new ones are coming online daily. But those typically take several hours to fully replenish a battery.

As a result, the ability for quick battery boosts — using a compatible direct current fast charger, the Leaf can refill to 80 percent capacity in 30 minutes — could potentially become an important point of differentiation among electric models.
