Tesla Supercharger

Tesla Superchargers are a network of 480-volt fast-charging stations built by Tesla Inc. to allow longer journeys for their all-electric manufactured vehicles (Model S, 3 and X), through quick charging of the vehicle's battery packs.

Tesla began building the network in 2012. As of 18 December 2016^[update], there were 769 stations globally, with 4,876 chargers. The Supercharger is a proprietary direct current (DC) technology that provides up to 120 kW of power per car (depending on circumstances), giving the 90 kWh Model S an additional 170 miles (270 km) of range in about 30 minutes charge and a full charge in around 75 minutes. A software update provided in 2015 to all Tesla cars uses demand information from each Supercharger station to plan the fastest route, if charging will be necessary to reach the destination.

Supercharging is free for all Tesla Model S and Model X cars that were ordered before January 15, 2017 or for vehicles that were purchased using a referral code. Cars that were ordered from 2017 onwards are limited to free 400 kWh (about 1,000 miles or 1,600 km) per year. Beyond that, supercharging will have a fee, but at a lower price than filling up a gas-powered car. As of December 16, 2016, a car that remains connected to a Supercharger after being fully charged will be charged an idle fee of $0.40 a minute. This fee is waived if the car is removed in five minutes. Any incurred fees will be paid at the next service visit.

As of April 2017, Tesla plans to expand from approximately 9,000 charging stations to 15,000 during 2017, in advance of the Model 3 rollout which they expect to put significant additional demand for use of the facilities.

Tesla supercharging stations charge with up to 145 kW of power distributed between two adjacent cars, with a maximum of 120 kW per car. That is up to 16 times as fast as public charging stations; they take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100%. The charging stations provide high-power direct-current (DC) charging power directly to the battery, bypassing the internal charging power supply. The next version of Supercharging is expected to charge with more than 350 kW.
