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.
Such convenience is one of the key advantages of an electric vehicle, although it comes with two drawbacks: short range (sometimes less than 60 miles) and long charging times. Unless you can afford a $70,000 Tesla Model S, which goes up to 300 miles on a charge, there's not much you can do about an electric vehicle's limited range. But you can improve the charging time by installing a Level 2 (240-volt) charger at home. For a pure EV, a Level 2 charger cuts the time it takes to replenish the battery from more than 18 hours with a 110-volt wall plug to as little as 3 hours.
