The road trip is a classic theme in U.S. popular culture and a staple of the summer vacation—a chance to recharge the batteries. For owners of electric vehicles (EVs), that’s not just a metaphor. Far from their usual home or work plug-in sites, they consult apps and map out routes that will get them to the next charging station down the road. The fear of running out of charge—range anxiety—has always been a barrier to EV adoption, especially in a country as big as the United States. But as longer-range electric vehicles come on the market and the charging infrastructure ramps up, that may be starting to change.
