    Before the Twin Falls, ID supercharger comes online, I had to attempt Tremonton to Boise direct. I'll post a follow up on the return in a few days.

    272 Miles @ 255wh/mi, 69.3kWh.

    Left Tremonton on a full charge, 256RM is my current 100% but, hopefully after my return that number will be recalculated and increase.

    82MPH in Neutral, or 5 totally free miles.

    Getting closer to Boise, no fear of not making it now. A chance to go the speed limit!

    Ohhh construction, forced me to slow down. Goal was to pull into Boise SC with 0RM remaining... Oh well.

    Nice work! Just did this same route a few weeks ago. I stopped overnight at a 14-50 on PlugShare in Twin Falls that worked great so I could go fast and not worry, but nice to know you made it!!

    That was a long drive on one charge. Nice planning and work!

    Nicely done indeed. Any idea how that would look in late-December give the low temps?

    I'm planning on attempting Tremonton SC to Jackson, WY right around Christmas time. I don't suppose it would be a good idea to try it in one shot, would it?

    I have been waiting for the Erie, PA supercharger to open before I can drive my 70D from Gaithersburg, MD to Toronto, ON - but this is encouraging. Cranberry Township SC to Buffalo SC is 205.3. So even at 300wh/m, it would be about 61KW. The question is can I squeeze 61 out of a 70KW with just the seat heaters going?

    Would be so much easier if there was a SC in Erie, PA, but I can go to the Nissan dealer if need be.

    Twin Falls SC has the permit. It shows to be online before the end of the year.

    Sweet! Any ideas about whether Idaho Falls or Pocatello also got a permit?

    I will be doing this leg next month. Wish they'd hurry up and build the Twin Falls Supercharger, but I know it won't be available, even if they start construction now. I sure as heck won't be attempting this segment without stopping in Twin Falls. :D Still, very cool that you were able to make it, and thanks for sharing your experience!

    I'll be taking a different route (through California) on my return trip, so won't have to worry about that segment again..

    MMH: Thanks for this! It brings back lots of memories from our trip between Minneapolis - Spokane and back. If I'd had you nerve, I would not have stopped to charge in Gillette Wyoming at the Crazy Woman RV Park. Can you tell me how you generated the graph of speed and elevation change at the top of your post.

    This chart shows how I planned each checkpoint along the way to ensure I had enough energy to reach the next checkpoint and final destination.
    boitrestats.jpg

    Planning was done using EV Trip Planner and the following algorithms:
    ( Current RM / Distance ) x 280 = [Maximum usable wh/mi]
    e.g. Tremonton to Boise is 272 Miles and I started with 257 RM, thus:
    ( 257 / 272 ) x 280
    0.945 x 280 = 264wh/mi maximum usable for the entire trip.

    From there I can break the trip up into segments and allocate an amount of energy to each segment.

    The "magic number" of 280 is how many watt-hours the Model S says equals one rated mile, which can be determined by doing:
    (Start RM - End RM) / Total Distance = Percentage offset
    Avg wh/mi / Percentage offset = Rated wh/mi

    From other forum posts, seems like most Teslas use about 280wh per RM.

    Interestingly enough (because math is awesome), you can also determine about how much useable energy is in the battery by doing:
    Remaining RM * 280 = remaining(ish... only way to know with 100% certainty is to use it all) watt-hours.
    e.g:
    57RM * 280 = 15960wh (15.9kWh) remaining in battery.



    I Completed the return trip on Tuesday. I took the return a bit slower because of the elevation climb near the end, but now that I've done it once, if I were to do it again, I'd cruise around 60mph for the majority of the trip instead of 50mph.

    -11% to Tremonton! Ha! I laugh in the trip planners general direction.

    Fully charged, ticked up to 258RM, nice!

    I was being very conservative on the way back, because the 3000' climb had me slightly concerned. Once I realized I was going to have more than enough energy left over, I tried to make up for lost time.

    According to ev trip planner, done at 50MPH (assuming 15F and running the heater), it looks doable, but I would plan on have backup charging options (like rv parks) along the way if your enegry runs too low. Looks like there may also be some good charging options on plugshare along the way too.

    There's an entire thread for Twin Falls (Twin Falls, Idaho supercharger), I'm very happy Twin Falls is coming online. Next time I drive up to Boise, I should be able to do it again 80MPH the entire way =D that's why I had to get this direct one-shot done before then, this just wouldn't have been as exciting.

    I use a Garmin GPSMAP 62stc (Amazon.com: Garmin GPSMAP 62stc Handheld Navigator: GPS Navigation) for data logging on all road trips (I suspect, but haven't verified, that any Garmin device would work) After a trip, I use Garmin's Basecamp (BaseCamp | Garmin | United States) to load the GPS data and generate the graphs that I want. Google Earth could also be used, but GE mostly mostly annoys me.

    Holy cow, @mmh! You are a madman, and I mean that in a good way. That is incredible. I just went down to SLC and back this past weekend for Comic Con. I did Boise to Elko Nevada in one shot, where the car's nav was telling me I would arrive with -2% remaining, but it was fine. I couldn't stomach doing that Tremonton to Boise leg without charging.

    Maybe I missed it, but what model do you have? I calculate a Wh/rated mile of 284 which is different than the S/P85, so I'm guessing you have a D. I also saw that you have 73kWh of battery which is average for a car with your mileage.

    Did you have range mode off? That would give slightly higher numbers than the more typical 278Wh/RM.

    In a previous post: Bjørn's Tesla Model S videos - Page 54
    I came up with 280wh/rm with range mode off. For this trip, I had range mode on for most of the journey as you can seen in the pictures of the main display.
