First of all, as your article shows, batteries rarely need replacement at all, even at very high mileage. And those are old vehicles, battery management and cell chemistry are much better now.

And when they do, it's usually just a few cells that need replacing. In Europe, there are specialized third party repair shops that can do it a fraction of the cost of a new battery: https://www.smart-emotion.de/article/431-cell-replacement-at...

Lots of real world data shows that the TCO of EVs is much lower - fewer moving parts, less complexity, less maintenance.

The article linked speaks of 70 to 80k yuan, which I then turned into euros

for parts only, in china

but, sure, fair enough.
