Last year, Patrick Anderson went electric: He got a Porsche Taycan EV in dark blue.
Anderson, who is CEO of East Lansing-based economic consulting firm Anderson Economic Group, loves the zippy acceleration and "exciting" features the car offers. He also gets satisfaction in knowing that driving an EV benefits the environment, he said. 

But Anderson's joy comes with a dark side.
"They are a wonderful driving experience. But at the same time, they're an enormous burden in time and in energy in finding chargers and getting them charged," Anderson said. "And you’re not really saving much in terms of charging costs ... you may be paying more.”

Costs to drive an EV compared with a gasoline car are detailed in a report Anderson Economic released Thursday called "Comparison: Real World Cost of Fueling EVs and ICE Vehicles."
The study has four major findings:
There are four additional costs to powering EVs beyond electricity: cost of a home charger, commercial charging, the EV tax and "deadhead" miles.
For now, EVs cost more to power than gasoline costs to fuel an internal combustion car that gets reasonable gas mileage. 
Charging costs vary more widely than gasoline prices. 
There are significant time costs to finding reliable public chargers – even then a charger could take 30 minutes to go from 20% to an 80% charge.

Anderson has worked with the auto industry for 20 years and given the industry's transition to EVs, the group decided to do the studies to assess the likelihood consumer will adopt the cars.

...

"Part of the strength of the analysis is we’re showing the real-world costs that EV drivers face," Anderson said. "You typically have to go to a commercial charger and commercial charger rates are two, three or four times that of residential charger rates."

Then, there are the "deadhead miles" car owners spend driving around trying to find a commercial charger. Even charging at home on a Level 1 or Level 2 charger is time consuming and expensive. 

...

Anderson's report considers four costs beyond the cost of residential electricity when calculating how much it costs to drive an EV: 

- Cost of the residential charger
- Cost of commercial electricity
- An annual EV tax
- Deadhead miles to get to a fast charger

Given all of that, the conclusion is EVs cost more to "fuel" than gasoline cars that get reasonable gas mileage, Anderson said. It all depends on how the car is used and how much commercial charging is involved. 

A mid-priced internal combustion car that gets 33 miles per gallon would cost $8.58 in overall costs to drive 100 miles at $2.81 a gallon, the study found. But a mid-priced EV, such as Chevrolet Bolt, Nissan Leaf or a Tesla Model 3, would cost $12.95 to drive 100 miles in terms of costs that include recharging the vehicle using mostly a commercial charger.
On a yearly basis, assuming the mid-priced cars traveled 12,000 miles, it would cost  $1,030 to drive an internal combustion car and $1,554 to drive an EV. 
For luxury cars that get 26 miles per gallon and use premium gas at $3.25 a gallon, the cost to drive an internal combustion car 100 miles is $12.60. The cost to drive a luxury EV, such as a Taycan, Tesla Model S or X or Jaguar I-Pace, is $15.52 to travel 100 miles. That is using mostly commercial chargers. 
“That’s apples to apples and includes the extra EV taxes, the commercial charging and the home charging and the allowance of driving to a gas station, which, for most Americans, is very short compared to driving to a commercial charger for an EV owner," Anderson said.

The study differs from some reports that show it's cheaper to drive an EV than a conventional car. For example, a 2018 study from the University of Michigan's Transportation Research Institute found the average cost to operate an EV in the U.S. was $485 per year compared with a gasoline-powered vehicle at $1,117. Anderson said most studies include only the cost of residential electricity and don't factor in the four other costs that this study does.

...

Charging costs vary much more for EVs than gasoline prices, too, by 100% or more from month-to-month or week-to-week, Anderson said. 
"Even if you drive to the most expensive gas station, your varying price won’t be as great as that," he said.

“That’s going to be a big surprise to a lot of drivers," Anderson said, adding that many commercial chargers will also require the EV driver to enroll and sometimes pay a $20 fee, but that might be reimbursed with charging.
Also, don't plan on ever having a 100% charge on your EV, he said. 
"It’s very difficult to charge it up to 100%," Anderson said. "The chargers slow down and the manufacturers warn you not to do it because there is additional burden on the battery system when you get your vehicle above a 90% charge.”

That means if the vehicle advertises a range of 240 miles on a full charge, a driver in reality will get considerably less on, say, an 80% charge, he said.
For new EV drivers these costs, time constraints and other considerations are often a surprise, Anderson said.
“Unlike their reliable gas cars that have 300 or 400 miles of range that can be filled up at a number of gas stations in our country, you have to think about what available chargers you have and plan it out," Anderson said. "It’s more than range anxiety, it’s a burden of constantly monitoring the charging status.”
The Anderson report lists about two dozen sources in its research, which relied on consumer experiences and costs for drivers that go beyond government data on fuel economy and electricity prices. Anderson said it did stopwatch measurements of the time required to refuel gasoline cars and EVs, recorded customer experiences on reliability of chargers, charging time and costs. It used consumer reports from actual EV drivers, including those posted on forums for Taycan and Tesla drivers, Reddit and applications serving EV drivers such as PlugShare and ChargePoint.

My Prius prime gets 55 mpg in pure gasoline mode. I paid $3.799 this week for gasoline in San Jose. About 7 cents per mile.
According to the website, my Prius Prime will consume 0.25 kw-hr to travel one mile. Paid my PG&E bill last week, average cost was $0.40 per kwhr. This roughs out to 10 cents per mile, about 40% higher cost than gasoline.
And NO, I will not save $ with some kind of other "EV-charging-at-home" plan which sets punitively high rates for when not charging the EV.


That was a pretty epic rant; hard to argue with anything you said. I'm afraid to look at my electric bill this month as I'm sure I'll be hitting that $.40 per kwhr (not a net positive solar producer during the winter). Pretty wild that EV-2A rate schedule is $.55 per kwHr PEAK (4-9pm). Yeah, no thanks. The California Dream is over (hello NEM-3 !). Irony is that folks with cheap electric rates ($.15 per kwhr) would do well (or at least better) with an EV.
That said, I'm California poor and may try to cash in on the $4k used EV federal tax credit. Just gotta find a dealer...

I don't have solar, but have the EV plan with SDG&E and pay $.14 kwh during super off-peak when I charge overnight. I get about 3.3 - 3.8 miles per kilowatt. So about 4 cents a mile.

Hybrids are great bridge vehicle to transition, but they are way more complex to build and maintain compared to a straight-up BEV. Obviously batteries are still massively expensive, but EV's have way less moving parts and components to wear out. No transmissions, oil changes, brake jobs etc....

Tesla continues to do amazing things driving down the price of batteries and getting more range. Imagine where we will be in another 10 years?

We don't need the government forcing this. EV adoption will happen on its own through market forces as EV's truly become superior in every way.

Oh my! 81 cents per kwHr peak during the summer.

Thank God I don't have (or need) AC. I would be broke! As it is, I am always chasing after my kids turning off lights during On-Peak times. Ceiling fans running all night is not too bad.

We get the Super Off-Peak rate through 2:00PM on the weekends so we do all of our laundry on the weekends. We run the dishwasher at midnight too.

Since I went with this plan, my consumption went up over 20% but my bill went down a few bucks taking advantage of the lower rates at night.

Engine and transmission can last 1/4 million miles and 20+ years, especially without government mpg regulation forcing manufacturers into small displacement turbos. No lithium battery can last 20+ years. Brake jobs are necessary on BEV's every year due to rust/sticking thanks to lack of use. "Less moving" is not a good thing when it comes to brakes. The heavy weight of massive battery wears out tires and suspension components faster, and especially wears out public roads fast, which requires asphalt and concrete to repave, both of which generate enormous amount of CO2 in production. What the heck are the refineries supposed to do with gasoline as byproduct in the production of asphalt, synthetic rubber and plastic? Making Molotov Cocktails?

We will see. The original Model S's on the road now are about 10 years old and I am not seeing a bunch of reports of major battery degradation yet.

True about the weight of the car and impact on infrastructure. That will get better over time with less batteries/weight as they improve drive train efficiency and energy density. Tesla already uses less batteries than most other EV's in the market and gets better range.

I think people who own a home and have a garage where they can charge, and who also own more than one car for the family (so the other car can be a gas car) can make good use of electric cars.

This is spot on. I appreciate your thoughtful post. You are 100% correct that electric vehicles can make an excellent 2nd vehicle in a large number of households. They can make a great vehicle in a bunch of other circumstances, too.

Unfortunately, electric cars have become a yet another political hot topic. The over-eager government (and certain types of people) pushing electrics are actually creating stubborn resistance. Jumpstarting an industry to get above a point of sufficient quantity can be a useful strategy, but I don't think electric cars need so much push that a whole bunch of people have a bad experience.

About to become more expensive to charge the EV.

EV Charging Station SPACs go SPLAT!

Chargepoint is a fucking joke: their shitty chargers are just 6kW, which means it takes fucking hours to add any meaningful range.

I'm not sure about lack of use part: I once was at a stoplight next to a ModelX and noticed that the front brake rotor had a very pronounced ridge around the edge, meaning they were at least 1-2mm down from the original thickness. Now, this is not unusual for ICE cars and on average happens after 50-80K miles (depending on the pad compaund), but having this much wear doesn't really fit with the "EVs don't use brakes at all" narrative. Of course that ModelX could've had 400K miles on the clock - we'll never know.

Most of them are. Especially public (government) bathrooms...er, chargers.
