The Dept of Energy has a web site that lists EV Charger locations, public and private, and even has a Locator / Trip Planner: Alternative Fuels and Advanced Vehicles Data Center: Alternative Fueling Station Locator Currently, there are 7197 EV stations Nationwide as of this post (see Alternative Fuels and Advanced Vehicles Data Center: Alternative Fueling Station Total Counts by State and Fuel Type) Finally, you can download the data in a CSV format here: Alternative Fuels and Advanced Vehicles Data Center
I put all these into a google earth file for easier navigation...next up trying to add all this to the POI database in the Roadster :smile: alt_fuel_stations (Apr 5 2012).kmz
