Replacing EV batteries is very rare, even in older or very used EV’s

Unfortunately used EVs are still decades away from being viable since after 10 years you hit the point you most likely start needing to replace the battery. You aren’t buying used if you need to invest more in replacement parts than the car itself.
I’m fine with that though, we need vehicles on rails instead. 80% of all microplastic are from tires.

They don’t seem to mention how fast batteries actually degrade, how old those vehicles are, what climate conditions they are used or how many charging cycles are on those. It’s all well and good if the 15000 cars have a low amount of battery replacements but without knowing the conditions it’s kinda useless.
Like where I am the temperature goes from -20C to +30C pretty much every year and in those conditions the makers rate the lifespan from 8 - 12 years.

It would be nice if they provided that information but the data isn’t useless without that information. It helps show that there’s a pattern where batteries only lose 10% capacity after being driven a lot.
You can assume that EV’s with higher milage will have been charged far more often than those with less mileage.
Canadian here and yeah, it can get down to -30C and +30C here but remember all batteries are insulated and they run glycol though them to keep them at a constant temperature which negates any external factors like weather. Polestar does their testing in the Artic circle so it’s even colder so if it works well there, it’ll work well anywhere.
With more EV’s sold and more time passed, only then will we better understand battery life but based on what I’m seeing, it’s a minor issue that won’t stop me from buying an EV.

Tire runoff is nasty. There’s recently been salmon die off in the NW from a preservative chemical in tires.

Batteries don’t suddenly die, but lose capacity over time. I believe batteries are already demonstrating 80+% capacity after ten years, and they should only get better as technology improves.
LFP batteries used in lower end models, such as Tesla Model 3/Y Standard, are expected to hold capacity after many more charge cycles
