There are 19,975 level 2 charging stations and 2,368 DC fast charging stations to serve electric vehicles in the U.S. Over 60% of those charging stations are maintained by four networks: ChargePoint, Tesla, Blink, and SemaCharge, according to figures from the US Department of Energy.
Level 2 charging stations can be used residentially or commercially to provide electricity faster than a standard 120-volt outlet.
ChargePoint has the largest number of non-residential level 2 charging stations followed by Tesla. DC fast charging stations allow for long distance travel of EVs by providing quick recharge rates along highways and well-traveled corridors between metropolitan areas. The eVgo Network has the largest number of DC fast charging stations followed by Tesla with its SuperCharger network.
A station is a non-residential address where Electric Vehicle Supply Equipment (EVSE) are located, including both public and private stations. There may be several charging outlets at each station.
Level 2 Chargers deliver AC power that provides about 10-20 miles of range per hour of charging.
DC Fast Chargers deliver DC power that provides about 60-80 miles of range per 20 minutes of charging.[source: US DOE]
