Has any 85 kw Model S owners Max Charged their cars and got 300 mile range? So far I have Max Range Charged the car twice and only received 271 Rated.

Odd theory...This is a suspiciously exact number; it looks to me like there's a software bug. Perhaps it's counting seconds and using a 14 bit field to keep track of how many have elapsed; that could do it.

Chad, not sure a second charger would have helped me since 70A J-1772 units seem to be very rare in the wild and the standard L2 units and RV Park 14-50R outlets max out at 10KW or less anyway. If I had the elusive Roadster adapter it would be a different story as there are several Roadster HPC's along this route.
Your point is VERY well taken regarding CHAdeMO. It's painful to park next to an unused station that has the power but not the interface to top me off in an hour or two. With Superchargers imminent I don't expect to see a CHAdeMO adapter for Model S anytime soon. Call me a pessimist.
One more point. I've seen it mentioned here before but I'll say it again. NEVER EVER EVER trust a public J-1772 L2 unit to do an overnight charge without checking it frequently!!! I'll be spending an extra 6 hrs here at the Motel 6 because my charge aborted at 2:37AM this morning after 4.5 hours without a problem (and less than an hour after I last checked it before turning in). I don't know if it was the car or the EVSE that caused the charge to stop, I restarted it without issue, but Tesla needs to supply some sort of notification mechanism (email/text/in app notification) for interrupted charges! This should be BASIC functionality as it has a HUGE impact on cross country travel. Oh well, I guess the Siskiyou summit will just have to wait a few more hours for me to tackle it. My apologies for the off-topic rant.
PlugShare is a good site for finding charging. You can search for free chargers only from the Settings menu, as well as filtering out unhelpful chargers (e.g. Avcon paddles).Which site do you use to seek out the free chargers?
Did you charge at each of those intervals? How long did you stay at each location? And free charging--that's pretty awesome. Which site do you use to seek out the free chargers?
I did charge at each stop; I hope to find time to put up another post about charging this week (and I'll link to it from this thread).
Wow… that is spot on with my experience so far (winter driving, 21", rain). I was just looking for reasons why 238 miles keep turning into 180.
Thank you SO MUCH for this incredible resource.
Update: Added to the FAQ:
4.2What's the real world range (for each battery capacity)?
If I understand you, that sounds about right, aviators. At 70 degrees and 60mph Tesla says HVAC is included in rated range. By 100 degrees AC should cost around 7%, but at 80 degrees I would think it would only be a percent or so (it's non-linear).
The green line at the top is the Range vs Speed with no HVAC?
The green shaded portion of the graph shows the effect of HVAC and the bottom of the shaded area is the Range vs Speed with the HVAC on maximum?
Range calculators
Tesla’s range calculator is attractive and easy to use. It seems to be pretty accurate. It says that if you go 65mph on level dry ground with HVAC on at 32 degrees, you will get 218 miles. That’s using 118% of rated miles to go 5mph faster and use more HVAC. But what if you go even faster than 65? What if it’s colder than 32 degrees? What if there is rain or snow on the ground? What about elevation changes? I asked Tesla to add these items to their calculator long ago, but no word on when or if they will.
HERE is another calculator that takes elevation in to account, and allows a wider range of speeds to be entered. But it doesn’t account for weather or road conditions at all.
Somewhere on these forums I saw mention of yet another calculator that sounds interesting, but it is Mac-only and I don’t have a Mac so I have not been able to try it. (EFusco found it for me: it's HERE).
Update Mar 2013: a Model S owner (Cliff Hannel on these forums) has been building his own version HERE. Forum thread HERE. It is not finished yet, but it appears to consider all of the relevant factors (speed, temperature, elevation, etc) except road conditions. This would be a great web page to have saved in your car's web browser.
