In short

Open data tracking federal highway coverage shows that just 2,547 of 15,927 public DC fast stations nationwide comply with NEVI standards. Significant transit gaps persist, with 881 highway stretches separating public fast chargers by more than 50 miles. Meanwhile, the broader public network encompasses 58,164 physical locations and 273,246 charging ports across all 50 states and Washington, D.C.

US EV Charging Open Data

Where public EV charging falls short along U.S. highways and in which counties, which DC fast stations meet the federal NEVI minimums or take a NACS plug, how chargers hold up, and how the network grows, county by county in Colorado and state by state. Every figure comes from our database or a named, dated, linked source.

The catalog today: 58,164 charging locations with 273,246 ports across all 50 states and DC. A charging location is one physical charging site: every charger at one address counts once. A port is one plug that can charge one car at a time.
