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.
Scott Briasco, of the Los Angeles Department of Water and Powerâs EV program, said that more than half of the 20,000 plug-in EVs in the utilityâs service area are charging this way. It isnât fast. Most cars charge at the rate of about 4 to 5 miles of range per hour. So, a mid-range vehicle like the Chevy Volt, with an all-electric range of 50 miles or so, will take 10 hours to completely recharge its battery. This kind of charging is relatively inexpensive and requires no special equipment.
