About

What's different

• Realtime, every minute. Most charger apps refresh availability when you reload the map. We poll the network APIs ourselves once a minute, every minute, and store the result. So a station that just freed up shows up here within 60 seconds, not whenever an app last got around to checking.
• Historical data per station. Every station has 14 days of hour-of-week heatmaps and uptime graphs. You can see whether a station is usually busy at 8pm Friday or whether half its stalls have been broken for a week. PlugShare and friends throw that data away.
• Drive + wait routing. The closest charger isn't always the fastest. If the one across the street has 4 cars ahead and the one 8 minutes away is empty, the math says drive. We do that math.
• DC fast only. We don't list L2 chargers. The list of DC fast stations is small enough to be tractable and that's the only kind you're looking for if you're road-tripping or out of juice.

How it works

The data comes from the chargers themselves. Every minute a cron job hits the public APIs of Electrify America, ChargePoint, EVgo, and Blink and records each station's available stalls and operational counts. We store the raw response so the data improves retroactively when we add new analyses. Coverage today is California, New York, and Texas. More states coming.

The system health page shows whether the polling is keeping up. The explore page lets you slice the historical data however you want.
