I wouldn't really suggest doing it. I was however, pretty confident, having had the car for almost 2 years now you get used to knowing how far it will go if you are monitoring your energy usage. If I get the wH/km to 170 over a 50 km window I pretty much know I can drive the number of km indicated by the car's gauge.
We NEED Kingston is an understatement

Very impress!
At 198 Wh/km it penalized (headwinds) you by 7% comparing to your initial Rated Range of 420 km. It brought you down to around a Rated Range of around 391 km.
Even if you substract 9 km (your detour to Kingston BW - go and come back on 401) you would not have been good to make it as you hit the 84.2 kWh mark for the whole Cornwall-Toronto trip... As I wrote friday you had the strong headwinds and that was my big question mark about that trip... Probably you could have done it if the winds wouldn't have been that strong... With a 182-188 Wh/km average you would have been probably OK (with some KM done after the 0 Rated Range mark)...
Here is a good pic that explain the battery «stages»... the 0 Rated Range comes when your consumption hit 75.9 kWh then you still have 5.1 kWh (+/- 20 km distance depending on your consumption at that time...).

Thanks for the diagram. Just a couple of questions: What is this 8.5 kWh range charge. Does that simply mean that you put the charge slider all the way to 100% and it charges up fully? Also, according to the diagram, the available for range driving is 75.9 kWh. On my Toronto Cornwall leg it showed me as having used 70.7 kWh and I only had a couple of km range listed. Shouldn't it have shown me more available if the "available for range driving" is 75.9 kWh? I was practically at zero? Maybe Tesla has changed this value since the diagram was made? My consumption upon reaching Cornwall was averaging below 170 wH/km so quite good.

Yep, it's the difference between Range charging and Normal charging.
Actually, range driving reaches reach 75.9 kWh and after that you hit the 0 Rated Range... though I can't explain the gap between your 70.7 kWh VS the 75.9 kWh with you having only couple of KM left on your rated range... let's not forget that this diagram is based on theory only... not sure it was done and calculated in real life...
To really know we would have to drive it to the point that we get to pull over because the battery depleted... measure the kWh done, the Wh/km consumed and we would have a pretty good idea of what is really the max km we can go (always depending on the average consumption) / or max kWw used until dead batteries... but we would need a flat bed towing to finish the experimentation though!
And yep 170 Wh / km for your return was pretty good. Winds, again, was one of the factors that yield that low consumption.

I guess that this 0 mile protection number is somewhat arbitrary and decided by Tesla (and is not some fixed in stone scientific basis number). Is it possible that Tesla, in more recent updates would have changed the amount of kWh before you hit the 0 mile protection and the diagram doesn't match reality anymore? Has anyone done any drive to flat bed test lol?
Interesting chart. I get a kick out of the fact that Tesla protects about 17.5kW of battery from normal use - which is slightly bigger than the entire Volt battery! No wonder The Tesla battery lasts so long versus other electric cars (and yes, I know, they use better chemistry too).
Simply having so much capacity effectively reduces the battery wear, as on a per kilometer basis there are fewer charge/discharge cycles.

Yeah, it's like having overprovisioning on a computer's solid-state drive. Helps boost longevity.
Still, that extra capacity would come in awfully handy...

I saw this yesterday too and I got my hopes up for a split second. I don't think its anything SC related though as the concrete was already done and I didn't see any wiring for the stalls. Also, I kept my eyes peeled for any crates, but didn't see any, or anything with a Tesla logo. They were starting beams on a 2nd unit when I was there. The crew looks pathetically small for the size of this job, I hope they are going to step it up soon, or it will be well into 2015 before this project is done!
@hingisfan
Thanks a lot for your research. However i am not convinced that this site is the actual location for the SC. Maybe you are looking in the wrong place? (just hoping ..)

Could this be some Tesla Energy Storage equipment? See the pictures at Tesla Supercharger network - Page 540 that clearly show "Energy Storage" on the labels. Energy Storage and peak leveling is another business that Tesla is entering.

This week, we opened Superchargers in Toronto and Cornwall in Ontario. This is a good start for Supercharging in Eastern Canada, and there is still work to be done.
Many sites are entering the zoning and permitting phase so we encourage you to show your continued support by writing, emailing, or calling utility companies and local government to let them know how important Supercharging is for you and local communities.
We continue to push forward to ensure that the major Canadian routes on our 2014 map are enabled as quickly as possible.
Eastern Canada:
o Priority routes: Toronto–Montreal, Montreal–Quebec City, Toronto–North Bay (via Barrie)
o Toronto, ON and Cornwall, ON are now open, and we realize the need for Kingston, ON to come online quickly in order to complete the Toronto–Montreal route.
o Drummondville, QC is on track to break ground shortly, enabling Montreal–Quebec City.
o Barrie, ON and other sites will open throughout fall depending on permitting and utility company timing.
Western Canada:
o Priority routes: Vancouver–Whistler, Vancouver–Banff, Calgary–Edmonton
o Squamish, BC, our first Canadian Supercharger site, opened in July.
o We have broken ground in Hope, BC, which is on track to be the next Western Canada Supercharger.
o Sites have been selected for the remaining five Supercharging locations along the Western Canada routes and we are now into the utility and permitting phases. Other sites will open throughout fall depending on permit and utility company timing.
As we navigate through the zoning, permitting, and utility company processes, we continue our policy to communicate firm timing and locations once we and our partners are sure a site will be open.

The TM Ownership account has only three posts, one to dispel HeartBleed vulnerability rumors, and two in this thread. Not sure what this means.
In any case, thanks to TM for paying contractors OT in order to complete Cornwall and Toronto before the holiday weekend. Now, if TM could just plan on Supercharging more of the Trans-Canada Highway East of Drummondville. After all, Quebec leads North America in lowest CO2 per kWh produced, so Supercharger sites there would do the most for offsetting CO2. Thank you.

Please keep us informed of developments as Kingston site will need a major stop on Ottawa-Toronto travel.

Here are some more pictures from today of the rumored Kingston supercharger site. Again, others who know more can comment, but I think this shows that this box is not for the superchargers and there's still no sign of any construction for the Kingston supercharger. Also, the yellow thing in the background is a dumpster, not a crate :smile:.
Given Tesla's message from today, I'm wondering (and hoping) if they have given up on waiting for this site to be ready and are considering another site.
I'm sure this has been mentioned before, but there is a conflict between this map and the one at Supercharger | Tesla Motors
The red dot over Chatham-Kent doesn't show up anymore on the teslamotors.com site, even if you expand out to 2015. I suspect TM Ownership's map (with a star over Chatham-Kent) is more accurate because a prior version was the first to reveal Barrie. Also, it's easier to overlook a site when you're maintaining maps of the world as opposed to concentrating on a region. However, does anyone have a more educated guess?
