Gas is 59 Cents per Gallon
If you are tired of high gas prices, get an electric car. I drive a Tesla Model X and am paying the equivalent of 59 cents/gallon for gas. Check my math below and put down that deposit for your favorite EV.
My car has a 75 KWh battery.
A car battery’s charging efficiency is between 80 and 89.5%. I used a figure of 85%. It takes 75/0.85 KWh, or 88 KWh, to fully charge the car’s battery.
The electric company charges me 9 cents/KWh to charge the car at night.
It costs me 88 KWh times $0.09, or $7.94, to “fill up” my car.
My car’s published range is 237 miles, but I actually get 201 miles. Or, about 85% of the published range.
Let’s assume that an equivalent gas burning SUV that can seat 7 people and weighs 6,500 pounds will get a mileage of 15 mpg. I think that I am being too generous and overlooking the fact that the gas SUV will never go from zero to 60 in 4 seconds.
At 15 mpg, the gas SUV will consume 13.4 gallons of gas to go 201 miles. That is, 201 miles divided by 15 mpg.
Since I am paying $7.94 to go the same 201 miles, my equivalent cost of gas is $7.94 divided by 13.4 gallons. Or 59 cents per gallon.
If you’re paying more than 59 cents per gallon at the pump, consider putting down a deposit for an EV.
If you have read this far, click this link to check my math. It’s a read-only Excel file. Ignore the numbers for the Model 3, I am still working on those. Not sure why the Model 3 appears to be more expensive to operate than the Model X. All input and comments are welcome.
