Owning an electric vehicle requires more than global-cooling ambitions. It takes guile, planning, sharp vision, a silver tongue and a 50-foot extension cord. Bernheim has become accomplished with each. He has to because his car runs only 25 miles on a complete electric charge.

SEATTLE — Owning an electric vehicle requires more than global-cooling ambitions. It takes guile, planning, sharp vision, a silver tongue —î and a 50-foot (16-meter) extension cord. Steve Bernheim knows accessible outlets like a firefighter knows hydrants. He has to —î his Corbin Sparrow runs only 25 miles (40 kilometers) on a charge. “You do guerrilla charging where you locate these plugs,” said Bernheim, an attorney who lives in the Seattle suburb of Edmonds. “I’m an expert at finding them.” While California has more than 500 public charging stations at parks, malls and grocery stores to serve electric vehicles that rolled out in the last decade, the network is still thin across the rest of the country, forcing drivers like Bernheim to get creative. That may change as charging stations crop up in San Jose, Seattle and Portland to serve early adopters and pave the way for a new breed of mass market plug-in cars. “Every auto company in the world is developing all-electric or plug-in hybrids,” said Zan Dubin Scott, a spokeswoman for Plug In America, a nonprofit advocacy group for electric car owners. “The utilities, municipalities and smart business people are seeing that this is the future.” The vast majority of electric vehicle owners charge their cars at home while they sleep, so most trips aren’t a problem. But drivers can now plug in —î reservations recommended — at two park-and-ride lots in King County, which includes Seattle.
