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.
Time to charge an electric car can take as little as 30 minutes or up to 12 hours. The time it takes to charge depends on the size of the battery and the speed of the charging point. A typical electric car (Nissan LEAF 30kWh) takes 4 hours to charge from empty with a 7kW home charging point. 3.7kW home charger provides about 15 miles per hour of charge. 7kW home charger provides about 30 miles per hour of charge.
