Many electric cars owners have been reveling in their purchases as gasoline prices reach record highs.
The national average for a gallon of gas hit $4.25 on Wednesday, up from $4.17 the day before, and it is expected to rise as the fallout of economic sanctions levied on Russia in response to its invasion of Ukraine continues to trickle through the petroleum industry.
U.S. electricity prices, which are heavily regulated in most states, have remained stable, however, and the cost to charge an electric car is still much lower than filling up one with an internal combustion engine, but only if you have a place to plug it in at home or a lot of time on your hands.
According to the EPA, the national average for a kilowatt-hour of electricity is 13 cents, including at homes where most electric car owners charge their vehicles with 240-volt Level 2 chargers that typically take eight hours or more to fill them up. Many of these are also available in public settings like office and shopping center parking lots, where they are known as destination chargers.
Things are much different at the Level 3 public DC fast-charging stations that allow some electric vehicles to recharge to 80% as quickly as 18 to 40 minutes, depending on the model and station speed, and are seen by some as the silver bullet that will make owning an electric car as convenient as a gas-powered one. Much of Tesla's success is attributed to its decision to roll out its proprietary network of Supercharger fast charging stations to support its owners.
On the Electrify America network that's compatible with all electric vehicles, fast-charge rates are as high as 43 cents per kilowatt-hour in some states, including California, New York, Florida and Washington. The price can be reduced to 31 cents by enrolling in a membership with a monthly fee.
At the higher rate, charging the entry-level version of the Ford Mustang Mach-E -- which has a starting price of $37,495 after federal tax credits are deducted and a range of 247 miles between charges -- would cost $2,100 annually for 15,000 miles of driving, compared to $1,500 at 31 cents and just $650 in an average home.
In contrast, a similarly sized Ford Escape Hybrid that starts at $32,780 and gets 41 mpg needs just $1,550 worth of gas each year to fill up at $4.25 per gallon, and it's $2,100 for a nonhybrid $27,755 Escape S rated at 30 mpg. In California, which has the highest priced gasoline at $5.57 per gallon, those costs would be $2,050 and $2,800.
Not everyone buys an electric car with the expectation of saving money, but it's important for anyone looking to cut costs to do the math on their particular situation before they write a check. As they say, your mileage -- and local energy prices -- will vary.
