Tesla Supercharger network

I found this document with some quick googling:
http://www.theevproject.com/download...ised%20(2).pdf

I haven't read it thoroughly yet, just glanced through it - but it provides a bunch of interesting information about demand charges.

It seems demand charges have large variations depending on the utility. So I could imagine that for EV fast-chargers specifically, they will eventually be regulated to max out at some reasonable value, by some political process.

During the LA test drive event I was able to get some unconfirmed info:

An announcement was coming only after the initial locations were built (keep your eyes out there should be activity as we type!) before the end of 2012.

There probably will be solar panels involved.

They may have found a way to cut the 30 min charge time to 15 mins! (wow ... if true)

It will be N/S & E/W on routes to major cities.

No info on how much supercharging is "too much"

Probably not. The math is pretty straightforward

If you've got an 85kWh battery and you pump 90kW per hour into it (which is the supercharger spec), then you will a half charge in 30 minutes if you have only minor charging losses.
If you've got the 60kWh battery and you pump 90kW into it (so a 1.5C rate, which isn't healthy), then you get a half charge in 20 minutes if you don't have any charging losses.

Thanks for the thread bump. It's more than halfway through July... with the giddiness Elon had hinting at the announcement at the shareholders meeting, I was hoping they'd have made it by now. Patience.... I must learn patience....

I'd bet TM will save all announcements for the earnings call at the end of the month.

Ah, I should have guessed as much.

[VolkerP]

While it is true that earning calls are used for announcements, the timeline is not "on the next earnings call". Remember the "order of (inaudible) magnitude drive train deal" that Elon announced back in 2011? It was confirmed just last quarter that it's about Daimler's electric B-class. So I get the impression that Elon sometimes jumps a little bit ahead of his buddies.

We can only hope rocket man does it again!

Totally agree with that, I think that's a large part of we love him so much!

from brianman's call transcript:

[Supercharger]
Anticipating a September event.... I'm really excited about that announcement. Way cooler than anyone realizes. I think it's going to have a profound

effect on how the public sees electric vehicles. There will be a few surprises.

I'm still a bit jaded, so when Elon gets really excited (a 8-9 range), I peg my excitement at around a 6-7, but I'm all ears.
