Tesla not waiting for your charging infrastructure...
 

Take Charge!...of supplying the juice. Tesla is planning to create a national network of high-speed 120 kW 'Supercharging' stations.
Fantastic Henry Ford-like vision, own your own proprietary 'fueling' infrastructure to your own brand EVs, and wait for it, charge it for free, for life!

It is an obvious analogy, Tesla (remember it not just a car company but a technology company) has seen & learned from the exponential growth of another industry, cellular communications. In the beginning of that industry it was not popular & problematic because early suppliers were limited to radio range & signal strengths, but soon widespread hexagonal cells and logical coverage made it practical and commonplace. Think of it as cellular-ization of EV transportation, and Tesla owns it first.
Hmm, another history lesson, a REVERSE General Motor Streetcar conspiracy...and hopes the same old major industries does not not BLOCK Tesla's idea(s).

120kW per car? Or the whole station can do 120kW?

Tesla Supercharger technology, faster charging. The new rate is 120 kW, which means you can add three hours of driving to a pack in "just over 20 minutes."

...looking at their planned infrastructure map (supported w/ onboard gps/driving routine/recharging software/app), it would be very practical for my personal/commuter routine.

On their website they talk about driving 55MPG. Good luck, but I think that most of us here would support it. 165 miles. On their website, they show that it would take 5 hours and 11 minutes to charge that much with a 240 volt outlet, and almost 29 hours at 110v.

Will someone please explain how electricity works? :)

Their 240v High Power Wall Connector does the job in 2 hours and 35 minutes, so if you are on a road trip, you would spend almost as much time charging as driving. For people who can afford electric cars, I imagine the charging time is a major objection, as well as range, even though they probably drive further than something like a Leaf would allow infrequently, but charging seven times as fast, for free, should make Tesla far more popular.

I have seen arguments on here that the company will likely not be around for several years, but I think that this plan could really help, and then electric car technology should progress much faster.

Ooooh and swappable batteries too. Elon ain't waiting around for anybody, folks. I continue to be impressed.

The charging stations need to be closer together than half the range. When your destination is just short of a charging point, you don't want to start the return trip by having to move on towards that point but rather take the first one on the route back.

There will be food stores close to those charging points. That means there needs to be a charging station nearby whenever you get hungry if you don't want to lose time nor weight.

Average person spends 11 minutes or more at a gas station so 20 minute to charge an EV while driving a long trip is not bad at all! after a few hours of driving it's a good idea to get out and stretch anyway.
Their web site says they will have regular J1772 charging plugs as well, I wonder what the deal is to use one of them for charging other EV's.
I have't seen any official published cost, but the Tesla web site says that the super chargers are only free automatically to the upper two models of the Model S and that to use it for the lower version there is a one time fee ($2,000 I hear) not sure if that fee also adds hard ware to the vehicle or if the car just has a dead plug in the back.

One of the next phase of super chargers is putting one up about 30 miles from me, right off I-94, so it will be interesting to see where it ends up in that area.

FWIW, about the "only" drivers these days who drive 55 mph are those who are entering a freeway on-ramp on their way UP to their normal 65-75-80 mph 'jaunt.'

The base Model S has 208 miles of range (according to the Tesla site), the higher trims have 265 miles. How often do you really drive that far in one jaunt??? Chances are a Model S owner also probably has another vehicle. If they need to drive 500 miles in a day they can just take that. I'm really not even seeing a problem here.
