Keep in mind that most of the time, the battery will not be empty when you plug in, thus reducing charging time. To recharge a completely empty car battery from an ordinary 120-volt socket, the Chevy Volt plug-in hybrid would need 10 hours and the Nissan Leaf EV would need 20 hours.
Home owners who go this route can charge at a much faster clip. An EV with a 100-mile range, for example, could recharge at the rate of 20 to 25 miles per hour and go from empty to full in only four to five hours.
