GREEN: Tesla Unveils Charging Network
An initial network of 100 solar-powered Superchargers will provide free, fast charging for drivers of Tesla S and the company’s future battery-powered cars.

Tesla Motors is creating a network of 100 solar-powered charging stations for its electric vehicles nationwide by the end of 2015 featuring fast chargers that will be able to deliver three hours of highway driving range with a 30-minute charge.

And the best part, at least for Tesla S drivers: the charging is absolutely free.

Tesla CEO Elon Musk said each station will have between four and six charging ports and be located at key highway rest stops near established restaurants. The total cost will be between $20 million and $30 million for the entire network, Musk said.

Owners of other-brand electric vehicles – and even the original Tesla Roadster – will not be able to use the fast chargers because the 100-kilowatt charging current is too powerful for their lesser battery packs, Musk said. The system will only work with the Tesla Model S and future Tesla models.

The stations will get their power from solar panels mounted overhead, courtesy of Musk's sister company, Solar City. The panels will generate more power than charging cars can draw, so on a net basis, the stations will add to the electrical power grid even if cars are charging at night or in cloudy weather.

"We are giving Model S the ability to drive almost anywhere for free on pure sunlight," Musk said.

Tesla secretly developed four stations in Southern California and unveiled them operationally late on Sept. 24. Two more will go online in early October, with the web expanding to Las Vegas, northern California and Oregon by next summer, Musk said.

Within two years, most of the U.S. will be covered, with the following time being used to backfill areas so that eventually stations are no more than 200 miles apart, according to Tesla. Musk said similar-size networks will be placed in Europe and Asia starting next summer.

A network of fast-charge devices on U.S. highways is a way to overcome the problem of limited range, one of the challenges automakers cite for battery-powered cars. Tesla wants to become profitable as early as next year from sales of its $57,400 Model S and by supplying battery packs and motors to investors Daimler AG and Toyota Motor Corp.

The company's goal is to deliver at least 20,000 Model S sedans next year and achieve a gross profit margin of more than 25 percent, Musk told Bloomberg Television on Sept. 21.

Tesla said it aims to install superchargers in busy traffic corridors across the United States, "enabling fast, purely electric travel from Vancouver to San Diego, Miami to Montreal and Los Angeles to New York."
