Tesla’s already quite impressive Supercharger network of charging stations grew by around 50% in 2015, going by the latest figures from the company. The company’s DC fast-charging network now includes 593 stations and 3439 individual stalls — spread across North America, Europe, Asia, and Australia.
Those numbers represent a roughly 48% year-on-year increase in location numbers, and a 71% year-on-year increase in charging plug numbers. The company recently noted that it’ll be increasing plug numbers at many stations, presumably in anticipation of the launch of the Model 3 and rising sales.
On that subject Green Car Reports recently had some interesting comments:
Some of those extra plugs may be crucially needed, as demand for Superchargers remains high during peak usage periods. Over the holiday season, increased traffic led to congestion at several Supercharger sites during one of the busiest times for travel of the year.
At the Tejon Ranch Supercharger site in Lebec, California, as many as 15 cars queued up at a time — and drivers waited up to two hours to plug in. Scenarios like this aren’t the norm for Supercharger users, but Tesla will likely have to continue coping increased congestion in the coming years.
A good point, though the Supercharger network is set to continue to grow rapidly over the next few years. (Take a look at the image below, depicting stations expected to be done by the end of the year.) That said, if Tesla does manage to sell half a million cars a year by 2020, then the network will need to grow exponentially before then.
