Re: Tesla's Superchargers: http://www.bloomberg.com/news/2012-09-2 ... hways.html
I stumbled across http://www.umtri.umich.edu/content/Bren ... T.2012.pdf which on page 44 gives of range of $23K to $45K to install a DC FC ($10 to 12K for a commercial grade EVSE).Tesla’s rocket-shaped superchargers are designed to work only with versions of Model S with 85-kilowatt-hour battery packs that allow the cars to go more than 200 miles per charge.
The devices cost about $250,000 each and can power four to six cars at one time, Musk said. Tesla plans to install 100 of these superchargers at a cost of $20 million to $30 million over the next three to four years, he said.
Long ago, Nissan bragged they got a CHAdeMO DC FC's cost/price down to below $10K. The $10K basic unit at https://web.archive.org/web/20120716030 ... sanqc.com/ vanished long ago w/any reason given.
