Tesla Model S Free Refueling On Tesla Motors Supercharger Network Now Covers Most Of The US West Coast (TSLA)

On Friday, Tesla Motors Inc. (NASDAQ:TSLA), the little electric car company with big ambitions, updated its map of Supercharger stations – the high-speed battery charger Tesla owners can use free of charge that tops the (electric) tank in 20 minutes.

Now you can travel pretty much the full length of the West Coast from Vancouver to San Diego free of both electric-car range anxiety and fuel cost. Two more Supercharger stations were added to the map on the west coast: one in Grants Pass, Ore., and the other in Mount Shasta, Calif. Four others were added in other parts of the country.

The latest map (above) of the U.S. Supercharger network, which is similar to telecommunication company maps indicating wireless network coverage, depicts how far you can travel from a company charging station before running out of juice.

Here’s the way the map looked on Thursday:

San Diego is 130 miles south of Los Angeles on Interstate 5, so if you’re heading south down from LA, the return trip to get back to the nearest Supercharger on one full battery would be impossible with the smaller 60 kWh battery (it has an advertised range of 208 miles) and a risky bet with the 85 kWh battery, with its 265 miles.

And if you want to head down to Mexico, you’ll definitely need to find an RV park or other outlet to re-up using add-on adapters.
