Electric cars hit a new global sales record in 2017 — 1 million cars sold, with more than half of that in China — but there may be a hitch to mass adoption: the number of adequate charging stations available. Before consumers take the plunge on a new electric car, they need to know that they can charge it.
The number of electric charging stations in the US is small but growing. As of September 2018, there are an estimated 22,000 public charging stations in the US and Canada that are classified as DC fast charging. (Typically, these supply 60 to 80 miles of range for every 20 minutes of charging.) By comparison, there are seven times more gas stations: about 168,000, according to FuelEconomy.gov.
