Since 2012, Tesla has invited its customers to plug in to chargers that add 200 to 300 miles of range per hour. The feature known as Supercharger Network-the world’s fastest charging solution.
According to the Teslas Blog post:-
But as of January 1, 2017 anyone who orders a Tesla will get just 400kwh of free supercharging credits per year, good for about 1,000 miles of driving. After that, using the fast chargers will incur a small fee, which has not yet specified. But it is mentioned that the prices may fluctuate over time and vary regionally based on the cost of electricity.
The new income will be used to build new Supercharger network. It’s likely that this fee will go toward expanding the network for the forthcoming Model 3.
The move means that those who buy Tesla’s mass-market $35,000 Model 3, which is due to go on sale in the second half of next year, won’t get unlimited free charging. Tesla has more than 300,000 reservations for the cars, and if all those owners started using supercharger stations for free, that could get expensive for Tesla
