Of course you have to take that into account. But it doesn't really change the math a lot.
BTW. I was talking about semis, not pickup trucks which is not really a common vehicle class in Europe where I live. People that use vehicles for work tend to use vans and trailers instead.
In any case, diesel engines get a lot of servicing (and unplanned down time) before they reach their 1 million miles. And the engine has many parts that need regular attention & replacing. An electrical motor is basically going to be fine with little to no attention until its end of life. Batteries do degrade depending on the chemistry. But decent LFP batteries are available now with many thousands of cycles before they start degrading. Other than that, the whole drive train just features a lot less moving parts that can break or wear out. Things like brakes, suspension, hydraulics, etc. of course work the same way and still need servicing.
And again, if you are burning > 100K$ fuel per year, replacing the battery once every few years is not that big of a deal in the grand scheme of things. And this wouldn't come as a surprise either if you run a fleet of these things. You'd plan and budget for that to happen.
And it's not like the old batteries are a complete write off. They have a lot of residual value. Even if they are completely dead, which they typically aren't, they would still contain a lot of valuable minerals (like a couple of hundred kilos of lithium), lots of copper, etc.
With battery cost now dipping below 100$/kwh and actually trending towards 50$/kwh, we're talking about component cost of 25-50K$ for a half mwh battery for the manufacturer. The real price would be higher of course (labor, various suppliers taking a cut, electronics and other stuff) but over time that should get closer to the cost price than is the case today. And that cost price will come down further.
There's an Australian company that converts trucks and says "the Janus fleet electrification solution will provide for up to a 60% reduction in maintenance and operating costs over the vehicle's lifetime." https://www.januselectric.com.au/
They are in operation on a number of large trucks.
