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.
From a depleted battery, it takes about 7 hours to fully charge a Nissan Leaf using the standard 240v home charging station. If using a 110v electric outlet, this would take approximately 20 hours. Quick-charging stations, which are currently more common in Europe, are starting to pop up in the US. Using a 480v line, it is able to give a full charge in just 30 minutes. Nissan began accepting orders for the 2012 Leaf in December.
