First, they amortize the cost of home charging infrastructure over 5 years, but personally, that's not how I think about those costs. When I'm comparing prices between cars, I'm considering the home charging as a one-time upfront cost. Once I've paid that cost it's not part of my ongoing costs to fuel the car.
You could argue that home charging infrastructure is a part of the cost of an electric car, sure, but if you're going to include that in the cost of the electric car, why not include the total cost of ownership for the ICE car as well (oil-changes, tuneups, emissions tests, etc.)? This article feels biased against EVs by only including additional costs of ownership for EVs and ignoring costs for ICs.
Also, high-voltage chargers for our home or commercial chargers on the road would be completely unnecessary for my family. We drive infrequently enough that an extension cord snaked to our driveway would be plenty of power.
Eeeehhhhhh... I don't think it's unfair.
The way I think of it would be capital cost to operating cost break even point. If it costs me $X install the equipment, but reduces my per distance operating costs, eventually at some point in the saved operating costs will overtake the initial upfront costs and you're outright saving money. Until that point through you're still technically behind in what you paid though.
I do think it's really weird to try and include it in a per KM operating costs as they did though. That's about as twisted up as Tesla saying the real cost of a car is the purchase price - the gas you don't burn price.
But at the same time, ignoring the cost of it is also weird to me as well if you want to talk about total cost of ownership. Once you've hit that break even, sure, but until then, eh.
And all of the taxes come from Michigan, which is one of those states that charge EV and hybrid owners extra to register and have lower gas prices than the rest of the country. I'm almost certain this would give a different result closer to the coasts.
This overall study feels like statistical cherry-picking to eeek out a marginal result.
If you compare instead in Texas at ~$3.4 a gallon / $0.14 a kWh, $9.86 / $4.06.
