    The average new car cost $ 35,742 and got 24.7 miles per gallon @ a cost of $ 2.88.
    Your cost will vary.
    So my Niro EV EX cost 8.6 % more with the heat pump/battery heater.
    So it could be said that my investment in a electric car is $ 3,062 if I was an average.

    My first month of use is 1330 miles. An average fuel cost would be $ 155.08

    I used a fast charger twice for about 60 Kwh. Total was 284 Kwh
    With the fast charge, cost was $ 62.81. If they had all been at home, cost would have been
    $ 46.71, However, home is solar pv and there is a free level two in town/ so cost is lower.

    So say average fuel cost ( $ 155.08) less niro ( $ 62.81) = $ 92.27. Yearly savings are
    $ 1,107.24 or a return on investment of 36% tax free. I am retired and this is the first month of use

    I'd probably agree that a 40k electric car could very well have a lower total cost of ownership than a 35k ICE car.

    However, if you are trying to minimize TCO, getting a new electric car for 40k doesn't even come close to the provably best strategy of getting used 3-year-old Toyota Camry's or Honda Civic's for 10k and driving them for 15 years.

    I have never been able to keep a car for fifteen years, most of the time it has six or eight years, when I traded to avoid a major repair. Also would the three year old Camry have a lower TCO than a three year old Leaf or BMW I3

    You're probably right, although where I'm at north of Seattle, you'll probably pay more like $15K for a vehicle that new.

    I'm in a similar position as the OP, going to be retired in 1 year and 1 week. I look at the EVs as a way to greatly expand what I'm able to do on fixed income. It's going to be damned hard to not worry about money and I think saving a few thousand on gas, AND having a newer reliable car will be a good investment.

    Don't forget the $7500 federal tax credit and any state incentives. That would be lower than your "average new car" cost...

    Took my first long trip. From Brattleboro, VT to Cornwall, Ontario. Round trip was 533 miles over three days. Drove about 230 miles of that at 62 mph. 5-1/2 to 6-1.2 hours each way. Maybe fifty minutes of charging in stops. Got another 30 Kwh by plugging in at the motel that I was staying at. ( 120 volt ) stayed two nights Averaged 4.6 miles per Kwh. There were fast charger in Vermont, but not in the area of New York that I drove through. IMG_0954.jpg

    so believing everything one reads, I did a 220 volt charge from 6% to 100%. It took 67 Kw over about ten hours. So that makes the capacity of the battery to be something like 71.5 Kw. The GOM said 320 when I disconnected. I think the range is closer to the WLTP european standard of 282 miles. The other thing which I have seem in a video is that it charges with no taper. I have a tesla Powerwall which has an app that tracks consumption and production from the PV system or the grid. Here are some pictures IMG_1003 (1).jpg IMG_1002.jpg IMG_1001.jpg

    I think you're assuming that L2 charging is 100% efficient (that 100% of the electricity from the wall ends up in the battery), but it's not. It's pretty efficient - somewhere north of 90%. That would mean that the 67kw used in that time probably put around 60 - 62kwh into the battery. At 64khw of usable capacity, if you started with 6%, that means you had a little less than 4Kwh remaining, with around 60Khw available to be charged. So, the math at 90% efficiency lines up pretty well.

    After two months, I have driven 2,888 or 48 miles per day. My average is 4.66 Kwh per miles, or 156 miles per gallon.
    My longest trip was 266 miles. left with 100%, charged at a 50kw charger for fifteen minutes and got 10.5 Kwh. Arrived home with about 30%
    That trip average 4.8 miles per Kwh.
    Cost is 4.08 cents per mile if I paid for all the home charging at the utility's rate, but I had enough extra Kwh from PV, so home charging was "free".
    Also, I used EVgo fast chargers for about 16%, which was 37% of the cost for the period. This will go down now that I have a home charger.
    The PV system is seven years old and I will have recovered it cost by March of next year. Time to buy more PV
