If you have a Rivian R1T or GMC Hummer, the cost to charge at home isn't much different; it's about $17.70 per 100 miles.

Assuming the manufacturers claims are accurate (which is a big assumtion I know) that R1T, at the current US average electricity price of $16.14 per kWh, is $7.26/100mi.

I think a lot of this depends on where and when you get these numbers. For example, there's a wider disparity between BC and Alberta because electricity is cheaper in BC while gas is more expensive.

Also, are we talking rapid charging stations or home charging a few times a week, because of course the commercial charging stations cost more, but some people may not need to use those except on some longer trips

The R1T description says the lowest battery size is 105 kWh with a range of 230 miles. This would give a "miles per kilowatt-hour" of 2.19 miles / kWh. Using the national average electricity price of $0.170 per kWh, the cost per mile is ($0.170/kWh) / (2.19 miles/kWh) = $0.0776/mile.

Using a Honda Ridgeline for gas equivalence, it has a combined 22 miles per gallon rating. With a national gasoline price average of $3.803 per gallon, the cost per mile is ($3.803/gallon) / (22 miles/gallon) = $0.172/mile.

So by these calculations the electric option is a little less than half the price of a gasoline equivalent. Perhaps charging the R1T in public with a premium, such as with superchargers, the cost per kWh may go up, but that's a disingenuous comparison so I agree with you that the article is making some big assumptions.
