Broken and malfunctioning chargers, erratic charging pricing and drivers of regular cars who park in spots reserved for electric vehicles are a significant obstacle to increasing EV sales, a study led by a Harvard Business School fellow has found.
Based on a decade of data obtained from EV drivers’ reviews of charging stations, the research found that charging stations in the US have an average reliability score of just 78%, meaning about one in five don’t work. That’s less reliable, on average, than regular gas stations, lead researcher Omar Asensio said.
