    …how? Like, it cost $30 (10 gal) to fill my petrol car in the states. Even if I was using 150kwh in electricity, at my power rate in Wisconsin ($.13/kWh), it’s $19.95. I live in Vietnam now, and pay 2500 VND per kWh, and petrol is about 23500vnd/litre. I have an electric moped that goes 110km/charge, and has a usable capacity of about 0.7kwh. I rarely empty the battery, but even if I did it daily, it would be .08USD/day.

    I’d like to see the math crunched on this.

    Edit: I found the math. It’s dishonest. Shocker.

      It’s actually not as bad as I was expecting. The electricity prices seem to be about right (17 cents per kwh at home, 43 cents at fast chargers), and the idea of having to drive farther to get to a charger is likely a reality for apartment dwellers.

      The two shitty parts are that they included the cost of the charger in this which is obviously a one time expense, and they calculated that “mostly at home” users would still supercharge 20% of the time, which seems like a TON. I put 21K miles on my car in the past year, and I supercharged 470/6897 total kWh, so 7%. If you rectify both those things in their math (let’s say maybe 10% is average?) then the “at home” EVs clearly win.

      But it is absolutely viable to point out that if you can’t charge at home (or at work, although I personally wouldn’t want to tie myself to an employer to be able to charge my car. I already hate that we do it for health insurance), then it is going to be much more expensive than for people who do, and possibly more expensive than similar gas cars. For example, I had a VW ID.4 for a year and it got AWFUL efficiency for my driving patterns (about 2 mi per kWh) and I exclusively fast charged at the local electrify america station because it was free.

      If I had had to pay retail price for the EA charging for the 10,000 miles that I drove, 48 cents per kWh * 5000 kWh, that would’ve cost me $2400 to charge, which is absolutely more than it would’ve cost to just drive our CRV instead (25mpg, $3.87 for gas over 10K miles = $1548).

        Oh yeah, absolutely. When I was stateside I put on better than 30k miles a year. An EV wasn’t a viable vehicle for me (for work anyway). Must people I know aren’t that though. Including the charger price as a constant is what inflated this, as well as commercial charging.
