As of 2015, there 409 Supercharger stations across North America, Europe, and Asia. According to CNN Money, it is possible to drive from California to New England for free using the Supercharger network.
According to Tesla Motors, Superchargers are connectors that charge Tesla Model S fuel cells for free. Stations are strategically placed along well-traveled highways and in congested city centers to facilitate long distance travel with as few stops as possible. For convenience, stations are typically located near restaurants, malls and wifi hot spots. A Supercharger station can provide 170 miles of range in as little as 30 minutes.
As of 2015, there are nearly 200 stations across the United State and Canada. Forty-three states have at least one Supercharging station and California has nearly 30. There are also over 140 stations in Europe, 62 across Japan and China and two stations in Australia.
In addition to Supercharger stations, many destination businesses such as ski resorts, restaurants, and hotels are partnering with Tesla to include dedicated wall connectors at their properties. These connectors require several hours to fully charge a fuel cell.
Supercharging relies on multiple Model S chargers working in parallel to deliver up to 120 kW of direct current (DC) power to the fuel cell. Any Model S with an 85 kWh battery is capable of Supercharging and it can be added to any Model S with a 60 kWh battery.
