More EVs are coming. Where's the infrastructure to support them?

There are less than 46,000 public EV chargers currently in the U.S.

Charging an electric vehicle is simple and painless -- if you have a charger installed at home.

Automakers are producing EVs at a feverish pace with government backing. Yet the number of public charging stations, critical for mass EV adoption, is lacking.

There are fewer than 46,000 EV public charging sites currently in the U.S., according to Department of Energy data. In comparison, the number of gasoline fueling stations in the country totals more than 150,000.

There are several EV-charging network providers currently in the market: EVgo, Blink, ChargePoint, Volta, Wallbox and Electrify America, which is owned by Volkswagen. These companies maintain, build, operate or lease their equipment to businesses, individuals and governments and offer subscription services to members.
