    With some down time, here are the SuperCharger bills, Little Rock listed twice:

    We left with $5.50 of battery stored electricity. I don’t remember how much was in the battery when we arrived but it was over 120 miles, ~$2.25.

    To add perspective, it costs ~$26 to drive 140 mi to Nashville in our BMW i3-REx using Electrify America and EVgo. It is only $6 in gas to return on the 112 mi direct route.

    Speculation, the Fort Smith RV park was pretty damp with a lot of mosquitoes. It is possible that one of them infected the back of my wife’s hand. It would be undetectable once the infection took hold.

    Is the Power Tier 2 the faster rate, and the 1 the charge up fully 'trickle' rate?

    @ Speculation,
    I'm thinking that this is somewhat unusual.
    The little critters are a GREAT way to spread diseases but an infection?
    Usually not so much.

    I'm gonna have to think about that some.
    Maybe the skitter poked a hole which was then subsequently infected.....

    Either way, I hope she's still on the mend.

      • Tier 1 applies while cars are charging at or below 60 kW and tier 2 applies while cars are charging above 60 kW. Tier 1 is half the cost of tier 2.
      • Tier 1 also applies anytime your vehicle is sharing Supercharger power with another car.

    I am extremely allergic to mosquito saliva. I have to be careful. A long time ago, I was wearing shorts and was bitten several times below the knee by mosquitos and they became infected quickly in a tropical environment. I went into septic shock and was paralyzed from the waste down. I was in the hospital (in a foreign country) for a week being treated with sulphur powder. I don't want to repeat that experience.

    Plenty of other critters out there, and any tiny wound can become a big issue.

    cnn article said supercharging is 26 cents/kwh. it is not the same everywhere, is it?

    I estimate $0.20/kWh in my area. It really comes down to charging strategies. The trip home, I will run an experiment and share the data.

    Just like gasoline and electricity.
    EV chargers just have the added wrinkle that the owner may not be able to directly charge for the kilowatts.

    Please check my calculation/method:

    Assuming around 3.8 miles per kwh for highway travel efficiency (240 miles rated for 50kwh usable pack is 4.8). So, to travel 50 miles requires 13 kwh (50 divided by 3.8) that at .20cents per kwh comes out to $2.63 cents to travel 50 miles. Does that sound about right?

    This is what our Model 3 showed when we arrived.

    Sad to say, the Ozark AR to Tulsa OK segment was free. It is 156 mi on that segment: 720 - 156 = 564 mi SuperCharger mi on road.

    We also had about 120 mi saved in battery on arrival. Hold that thought.

    It costs ~$16.50 in SuperCharger costs giving: $16.50 / (564 +120) ~= $0.024 per mile.

    So 220 Wh/mi: 220 / $0.024 ~= 8.8 kW/$ ... $0.114/kW.

    Different everywhere. Some states charge by kWh, some charge my minutes. But even within states they can change some. But they are all so cheap compared to gas I don't stress about it much.

    This silence about SuperCharging is a problem. My thinking is SuperCharger descriptions should include head-to-head cost with gasoline. Better than EPA metrics, use personal trip experience.

    Yep, for example, my 1200 mile 31 hour trip (that included a 10 hour hotel stop) only cost me $30 in Supercharging costs.

    That ‘1,200 mi’ cost our old Prius Prime:
    • 2 * 11 gal = 22 gal
    • $2.50 * 22 = $55
    Our Teslas cost ~1/2 that of an efficient Prius. That makes our Teslas 4-5x cheaper than the USA 25 MPG average.

    Yes, and if you have home charging with solar panels, your fuel is essentially "free." Here is an interesting update on solar adoption in the US:

    The US has reached a new milestone — 2 million total solar PV installations, according to Wood Mackenzie Power & Renewables and the Solar Energy Industries Association (SEIA).

    It took 40 years for the industry to hit 1 million installations, but it’s only taken three years to get from 1 million to 2 million installations. In total, the 2 million installations have a net capacity of more than 70 gigawatts.

    Wood Mackenzie forecasts two year gaps to hit the next “million” milestones, expecting that there will be 3 million installations in 2021 and 4 million in 2023. SEIA says that by 2024, 2.5 percent of all U.S. homes will have a solar installation.

    California represented 51 percent of the first million installations, but only accounted for 43 percent of the second million, as other states are accelerating their growth. South Carolina, Texas, Utah, Florida, Rhode Island, and Maryland are all listed as fast-growing solar states. Another GIF below shows how the top five US solar states have changed during recent years:
    (surprise, Massachusetts is now #5, replacing Hawaii, New York #4)

    at 5 miles/kwh, 1200 miles at 25 cents/kwh would cost $60.?

    Where did you get 5 miles/.kwh?
    The Tesla screen showed 220wh/mile which would be 45 miles/kwh.

    If you are referring to my 1200 miles for $30 trip it was because I left with a full charge for free and I got a free full charge at the hotel I was at. (I didn't stay at a nicer, more expensive place because it had charging, so it didn't cost anything to me.)
