Battery electric vehicles (BEVs) such as the Nissan Leaf and Ford Focus Electric are powered 100 percent by electricity. They have lithium-ion batteries and ranges of between 80 and 110 miles. That may not seem like much, but 75 percent of daily driving for an individual in the U.S. is under 40 miles per day. When they run out of electric charge, they must be hooked up to a recharger. It can take five hours to recharge a Nissan Leaf at a 240-volt charger, and more than 12 hours when connected to a standard 110-volt household outlet.
