Tesla Motors's mysterious Supercharger network was unveiled on Monday, which includes six Model S charging locations throughout California and parts of Nevada and Arizona.

The new stations are just the beginning, Tesla said. Superchargers will be installed in high-traffic areas across the U.S., from Vancouver to San Diego and Los Angeles to New York. Superchargers will begin testing in Europe and Asia in the second half of 2013.

At this point, however, charging booth are available in California's Folsom, Gilroy, Harris Ranch, Tejon Ranch, Barstow, and Los Angeles. Tesla Model S customers can charge up for free.

Developed internally and constructed in secret, the Supercharger stations utilize technology already present in the Model S vehicle, which helped keep costs down, Tesla said. The company is, however, working with SolarCity, which is supplying the electricity for the stations via its solar carport system.

The solar power systems are designed to generate more energy from the sun over the course of a year than Tesla vehicles consume, allowing a net positive transfer of solar power back to the electricity grid.

"Tesla's Supercharger network is a game changer for electric vehicles, providing long distance travel that has a level of convenience equivalent to gasoline cars for all practical purposes," CEO Elon Musk said in a statement.

"By making electric long distance travel at no cost, an impossibility for gasoline cars, Tesla is demonstrating just how fundamentally better electric transport can be," he continued. "We are giving Model S the ability to drive almost anywhere for free on pure sunlight."

The Supercharger is more than just a means to avoid spending $50 a week at the pump. Its technology is the most powerful to date, providing almost 100 kilowatts of power to Tesla's Model S, with the potential to grow up to 120 kilowatts in the future. In about 30 minutes, one charge can replenish three hours of driving at 60 mph.
