For Electric Car Owners, ‘Range Anxiety’ Gives Way to ‘Charging Time Trauma’br “Driving long distances and stopping for one to two hours is not something I would want to do,” said Mark McNabb, the chief executive of Electrify America, a Volkswagen subsidiarybr that is installing charging stations across the United States as part of the German automaker’s settlement for cheating on diesel emissions tests.br A Tesla, however, can use an adapter plug to charge at standard commercial stations,br and Electrify America says its charging stations will be compatible with a variety of plugs.br It takes a Level 1 charger about 30 hours to fully charge the electric version of the Ford Focus, which has a range of 115 miles.br Porsche’s Mission E electric vehicle is expected to be available by 2020,br and will be able to charge to a 250-mile range in 15 minutes, according to the carmaker.br The electric carmaker Tesla has a proprietary “supercharger” for its vehiclesbr that provides 120 kilowatts of power, adding 300 miles of range in 75 minutes.
