EVAtlasUSA

Stations shown are marked operating in the federal Alternative Fuel Data Center — a station can still be temporarily down or removed since the last update. Always check the network's own app before a trip.

Glossary

Plain-language definitions of the terms used across EVAtlasUSA.

DC fast charging
The fastest widely-available charging type — typically adds well over 100 miles of range in 20-30 minutes, depending on the vehicle and charger. Used for road trips and quick top-ups, not overnight charging.
Level 2 charging
Standard 240-volt charging — the kind found at homes, workplaces and most public parking. Takes hours rather than minutes, but is far more common than DC fast charging.
Level 1 charging
Charging from a standard 120-volt household outlet — the slowest option, adding only a few miles of range per hour. Rare at public stations; mostly relevant at home.
CCS (Combined Charging System)
The standard DC fast-charging connector for most non-Tesla EVs sold in the U.S. Shown here as "CCS (J1772 Combo)", the AFDC's own label for it.
CHAdeMO
An older DC fast-charging connector standard, used by some older EV models (notably early Nissan Leafs). Increasingly rare on new vehicles and new stations.
J1772
The standard connector for Level 1 and Level 2 (non-fast) charging on nearly all non-Tesla EVs sold in the U.S.
Tesla / NACS connector
Tesla's charging connector, used at Tesla Superchargers and increasingly opened up to other manufacturers as the North American Charging Standard (NACS). Shown here as reported by the AFDC.
AFDC (Alternative Fuel Data Center)
The federal database of alternative fuel stations — electric, propane, natural gas and more — operated by the National Laboratory of the Rockies (formerly NREL) for the U.S. Department of Energy. The source for every station on this site.
Operating status
Whether the AFDC currently lists a station as open ("operating") versus planned or temporarily unavailable. We only show operating stations, but this is a periodically-confirmed status, not a live feed.
Stations per 100,000 people
Our own calculation: a state's station count divided by its population, scaled to 100,000 residents. Measures build-out relative to population, not how convenient any one trip will be.
