EV Charging Stats

Number of Cumulative EV Sales vs. Cumulative EV Charging Stations | Ratio EVs to Charging Stations

Number of Public & Private Charging Locations (Sites) & Stations (Outlets) in the US (Through December 31, 2017)

As of December 31, 2017 there were an estimated 20,178 EV public and private charging locations (sites) in the US, with 17,526 (86.9%) being available to the public. With 48,472 total public charging stations, each location has an average of 2.75 stations/outlets.

Of these charing stations, 38,360 (79.6%) are Level 2 and 7,223 (15.0%) are DC fast charging stations.

Number of Charging Locations/Sites by Charging Network

Five of the nine charging networks in the AFDC database provide 75.8% of the public charging locations in the US, led by ChargePoint with a commanding 39.3% market share and 6,895 locations/sites. Tesla with an estimated 3,308 (18.9%) and Blink Network with 1,489 (8.5%) are a distant second and third. However, 3,801 (21.7%) of the locations in the AFDC database are not identified with any specific network.

Charging Station Types by Charging Network

Overall, 79.7% of the 48,472 installed public charging stations are Level 2 and 14.9% are DC fast charging stations, nearly 3 times the percentage of Level 1 charging stations (5%). With a 45.0% market share, ChargePoint has the most total charging stations/outlets by a long shot with 21,805. The top three companies have a combined market share of 72.0% – ChargePoint (45.0%), Tesla (19.6%) and Blink Network (7.4%).

ChargePoint also has the most Level 1 charging stations/outlets with 1,416 and Level 2 at 19,848. Not surprisingly, however, Tesla’s 3,782 Supercharger stations dominates the DC fast charging category. With 1,608 fast charging stations, EVgo has a commanding lead on second place. Interestingly, its fast charging stations comprise 80.7% of its charger network.

SemaConnect Network has zero fast charging stations, but 100% of its 1,988 charging stations are Level 2.

Notes on the AFDC Data

The data in the Alternative Fueling Station Locator is gathered and verified by the National Renewable Energy Laboratory (NREL), which obtains information about new stations from trade media, Clean Cities coordinators, a Submit New Station form on the Station Locator website, and through collaborating with infrastructure equipment and fuel providers, original equipment manufacturers (OEMs), and industry groups.

The Station Locator imports AeroVironment, Blink, ChargePoint, EVgo, and SemaCharge network station data directly from these networks on a daily basis.

Existing stations in the database are contacted at least once a year on an established schedule to verify they are still operational and providing the fuel specified. Based on an established data collection schedule, the database is updated on an ongoing basis. Stations that are no longer operational or no longer provide alternative fuel are removed from the database as they are identified.
