A total of 858 charging stations have been added by Tesla from September 2014 to September 2015, following the company’s “Destination Charging” program—accounting for 80% of Tesla’s charging points in the US.
Tesla operates two kinds of charging networks. First there are the “superchargers,” which can charge a Model S at over 480 km (300 miles) of range per hour. These are found near popular routes to facilitate road trips and, notably, can restore a battery to an 80% charge in 30 minutes or less. Such stations have charging rates that range from 90 kW to 135 kW. But there are plans to improve. Tesla has designs for Superchargers that can charge at a staggering 200 kW.
The second kind of charging station is “destination charging," designed to charge Model S units for longer periods of time after they arrive at their destinations. Such ports have about 50 kW of power. That's obviously considerably less than the Superchargers, but it is more than enough if you are stopping off for more than just an hour or two.
Tesla continues to partner with various restaurants and hotels to install these chargers across the nation for free, under the stipulation that Model S users are able to use it for free.
The brand has managed to more than double their number of charging locations in 2014, which was comprised of 371 Destination chargers and 117 Supercharger locations that totalled to 488 charging points. A year later, Tesla reports 1,346 charging points for Model S owners, totalling to 1,122 Destination chargers and 224 Superchargers.
The rapid rise of charging locations highlights Tesla’s push to make electric automobiles more accessible, useful and convenient for car owners.
