Tesla has announced an accelerated rollout of its Supercharger network.

Tesla has announced an accelerated rollout of its Supercharger network. The proprietary network, which works only with Tesla’s Model S, already covers California, Nevada and the DC-to-Boston corridor. It’s designed for intercity travel, enabling Model S drivers to travel for three hours, take a 20-30 minute break, and get back on the road charged up – free.

Tesla announced these goals in its press release:

• By the end of next month, there’ll be triple the number of Superchargers, including additional stations in California, coverage of the Vancouver-Seattle-Portland and Austin-Dallas regions, and sites in Illinois and Colorado.
• Within six months, the network will connect most of the major metro areas in the US and Canada, and make it possible to travel cross-country from LA to New York.
• A year from now, the network will span the continent, covering almost the entire population of the US and Canada.

Tesla is also improving the Supercharger system to cut charging time substantially. The new technology, which is now in beta and will be rolled out to customers this summer, will allow Model S to be charged at 120 kW, replenishing three hours of driving in just over 20 minutes.
