Battery lifetimes were initially cast at 5 years and more than half the car cost to replace. They have both got cheaper to replace, and have retained value after out of the car, and have had lifetimes extended. So, your input maths needs some adjustment. Maybe not "its zero" but its not as bad as you fear.
You didn't calculate TCO for the ICE maintenance costs and you need to: EV have significantly smaller maintenance so the component of high cost in a retained old petrol engine or diesel motor, is strongly in favour of the EV. I had two clutches and a gearbox replaced across the 17 year retention of my Mazda 6 on top of the expensive six monthly motor service.
Not downvoting you, but noting, you skewed the cost exposure risks i believe, quite badly.
Elaborate what? The car had six monthly service cycle and it was not cheap. The clutches and gearbox were down to careless driving technique. Electric motors don't get deployed with clutches and are mostly electronic continuously variable gearing and the service costs are significantly cheaper on average than for an ICE. It's that simple.
Please elaborate what you mean by expensive six monthly service. Did your regular service visits include additional items? What and why? And how much did they cost? I am curious what makes Mazda 6 regular service more than other ICE cars.
It was a 2003 model, we kept 17 years. Oil and filter and fluids and engine mounts and that nasty judder which developed. We never got out the door under $300.
