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.
However, how long you wait depends on the type of charging station or plug that you are using. Level 1 charging plugs are basically your everyday household outlets. For a Nissan Leaf which has a range of approximately 100 miles, this may mean over 22 hours of charging to reach full charge. But the fact of the matter is that you will rarely need your car to be at full charge. For an average American who travels 40 miles per day, a 9 hour charging stretch is enough for a normal amount of commuting the next day. Level 1 charging is perfect for cars like the Chevrolet Volt which is a plug-in hybrid with a 40 mile electric range. Overnight charging will result in full charge for this EV. With voltage of 110 V, a typical sedan will take about 20 hours to charge fully, if needed.
