I get 3.2 miles per kWh, and charging at home costs 16¢/kWh (in my last bill, that's the base rate plus the fuel rate per kWh that Alabama Power paid for their plants, plus 4% state tax). So with the 16K miles I drove in the past 12 months and charged from home (we drove 26K miles total, but 10K of those miles were charged away from home on trips), that comes out to needing 5,000 kWh to charge those 16K miles at home. At 16¢ per kWh, those 5,000 kWh added $800 total to my power bills over 12 months. Or if you want it broken down monthly, that's $67 to drive 1,300 miles.
In my case, throw in the fact that 80% of my home's power is free from solar, that includes the power used to charge the EV. So in my case it adds on average $13 to my power bill each month to drive 1,300 miles (100 miles for every $1 added to my power bill when charging at home).
Charging at fast chargers those other 10K miles in the past 12 months cost a total of $332. Or $33 for every 1K miles. If you add home charged miles plus road charged miles together, it cost $1,132 total to power the EV those 26K miles, which is $4.35 for every 100 miles. (For me with solar the totals are $972 for 26K miles, which is $3.74 for every 100 miles.)
To be fair, there are other costs involved. I pay annually an extra $200 EV fee when renewing my car tag (to pay my share of road upkeep because I'm not paying gas taxes except what little bit we drive the ICE pickup). Plus there's a little extra cost for insurance (no EV rider or anything like that, but full coverage on a more expensive vehicle means more expensive premiums, and EV's tend to be more expensive). In my case I count it as paying $70/month more for insurance, but most of that was because for me going EV meant replacing liability only coverage of an old used ICE car with full coverage of a new car (the EV). For other people, if the choice to go EV was over a new ICE car, the difference in insurance might be $10 or $20/month. Of course, those costs are fixed and unrelated to how much I drive it. So a lesson learned is don't get an EV unless you drive it enough for the gas and oil change savings to offset the extra regular fixed costs with an EV.
At least, those are my real world numbers of continuing costs for EV (not startup costs like a larger upfront cost for EV's or cost to install a circuit for charging). I can't say what other people's costs are.
Interesting... how much did your home charging system cost? And how much for the solar system for your home - and how many years until that has to be replaced?
Fueling electric vehicles costs roughly the equivalent of $17 a gallon: Study
“EV advocates claim that the cost of electricity for EV owners is equal to $1.21 per gallon of gasoline (Edison Electric Institute, 2021), but the cost of charging equipment and charging losses, averaged out over 10 years and 120,000 miles, is $1.38 per gallon equivalent on top of that. Adding the costs of the subsidies to the true cost of fueling an EV would equate to an EV owner paying $17.33 per gallon of gasoline,” study authors Brent Bennett and Jason Isaac write.
“And these estimates do not include the hundreds of billions more in subsidies in the Inflation Reduction Act (2022) for various aspects of the EV supply chain, particularly for battery manufacturing,” they add. “It is not an overstatement to say that the federal government is subsidizing EVs to a greater degree than even wind and solar electricity generation and embarking on an unprecedented endeavor to remake the entire American auto industry.”
Regulatory mandates were found to make up the highest chunk of the hidden costs.
The study also argues that hybrids are far more efficient than full EVs, but are ignored by the government.
