Electric Vehicle Charging Stations by State

The number of charging stations for plug-in vehicles has increased sharply in the last two years from less than a thousand nationwide in 2011 to over 18 thousand by June of 2013. This includes public and private charging stations, but does not include residential chargers. California has by far the most chargers of any state, accounting for just over a quarter of all the chargers nationwide. Charger installations have risen in nearly all states, but a dozen states, shown in the graph below, account for a majority of all installations.
