In Plugshare's recently released quarterly report (Q3 2015), we came across this graphic showing Tesla's public charging stations in the U.S.
As of September 2015, Tesla has 224 Superchargers (sites, not individual stalls) and a shocking 1,122 destination chargers installed.
If we use Plugshare's data to compare those figures to CHAdeMO and CCS, we find that in regards to fast chargers, CHAdeMO is still the clear leader with 1,337 in the U.S. (though we believe that Tesla still leads the way if we count individual charge points)
Meanwhile, CCS still lags far behind the fast-charge leaders.
