Nice Car, But How Do You Charge That Thing? Let Us Count The Ways

How long does it take to charge an electric vehicle? The question is more complicated than it seems, and that's a challenge for the auto industry.

Vehicles have different battery sizes, and charge at different speeds. The same vehicle at different chargers will experience wildly varying charge times.

And no matter what charger a driver uses, an electric vehicle requires a change in habits. That may be an obstacle for automakers who need to persuade sometimes skeptical car buyers to try their first electric vehicle.
