An anonymous reader writes from a report via The Verge: In response to a question about how the company would handle an influx of Model 3s to its Supercharging stations, which are currently offered as a free service to Tesla customers, Elon Musk said at Tesla's annual shareholder's conference in Mountain View, California, "it will not be free long distance for life unless you purchase that package." He did not specify what the "package" contained, nor did he say how much it would cost as an add-on with the purchase of a Model 3. His full quote reads: "Obviously, [free Supercharging] fundamentally has a cost. [...] The obvious thing to do is decouple that from the cost of the Model 3. So it will still be very cheap, and far cheaper than gasoline, to drive long-distance with the Model 3, but it will not be free long distance for life unless you purchase that package. I wish we could, but in order to achieve the economics, it has to be something like that." Tesla did recently announce their Gigafactory Grand Opening will be held on July 29, even if it isn't scheduled to begin production on lithium ion cells until next year.
