In Preparation For Model 3, Tesla Plans To Double the Size of Its Supercharger Network This Year (fortune.com) 177
An anonymous reader quotes a report from Fortune: Tesla says it will double the number of electric vehicle chargers in its network this year as the automaker prepares for the production of its mass-market vehicle the Model 3. The plan, announced Monday in a blog post on the company's website, will grow its global network of Superchargers from more than 5,400 today to more than 10,000 by the end of the year. Tesla, which had previously announced in its annual shareholder letter plans to double the network in North America, did not disclose the cost of such an ambitious expansion. Many sites will soon enter construction to open in advance of the summer travel season, according to Tesla. The company says it will add charging locations within city centers as well as highway sites this year. The goal is to make "charging ubiquitous in urban centers," Tesla says in its blog post. The company says it will build larger sites along busy travel routes to accommodate several dozen Teslas simultaneously. These larger sites will also have customer service centers.

It would be nice if Tesla included charging for other vehicles. There are only so many sites on major routes where you can connect a megawatt or two of chargers to the grid, and Tesla has been fighting other networks to get them.
It would just kind of suck if all the best spots were Tesla only. I say that as someone who plans to buy a Model 3.

Most other vehicles have lower capacity batteries so perhaps the pattern of charging and usage has been different up until now. Tesla owners might drive longer distances or prefer to charge at a station once a week whereas someone in a Leaf might be driving shorter distances and charging from home.
I expect that pattern will change in time. EVs like the Ioniq, Bolt and 2nd gen Leaf all have increased ranges and therefore the need for rapid charging will increase. Maybe the Bolt will get a software update or hardware revision for a faster charging rate. I expect that charging stations will receive iterative upgrades over time.

A lot of it simply comes down to battery size. As cells charge in parallel, then for a given cell chemistry and format, the rate you can safely charge is proportional to the vehicle's capacity. And Teslas have huge capacities compared to most other EVs (for example, the Ioniq is only 28kWh).
Now, of course, that's conditional on vehicles using the same types of cells. For example, if one vehicle is using cobalt-based 18650s and another is using, say LiPo or high-rate spinel cells, then the latter can take a

You are Just Plain Wrong. The Supercharger network is a competitive advantage. Since no one else offers that, and no one else can charge at those points, as long as Tesla has it and nobody else does, it is a significant inducement to buy Tesla instead of something else.

God knows how much electric 100,000 fast-charging stations pull. I doubt it's any more environmentally friendly than even 100,000 petrol cars.
Yes, supercharging is much worse for the environment than regular charging. The grids don't deliver enough juice for them at peak, and they have to store energy locally in battery buffers. That's another quite lossy conversion. And supercharging isn't as energy efficient in itself either - the heat loss is larger than with slower charging.
In countries that produce a good part of the electricity from coal and oil, that's not a good thing.

That might be one of the most strained arguments I've ever heard. Talk about missing the big picture...

Even if we stipulate that is true, it still better than burning fossil fuels to move a vehicle. A lot better. Just because the heat loss is some arbitrary amount larger when charging quickly doesn't make it a bad idea. Slow charging is only useful in a garage overnight when you aren't going to use the car for many hours. Any heat losses for rapid charging are more than made up for by not burning gasol

Glad you set Elon straight with him not knowing what he's doing.
