the life span stat with the current battery tech is mostly useless for a normal car. 300 mile range most people will need to top up 2 times a week 100 times a year 1000 times in 10 years. The battery degradation is not that bad in the first place.
When it comes to as-fast-as-possible charging, I think you can divide that number by at least 10. Slow charging while parked overnight or during the day should still be the most common case by far for most users. Very fast charging is important for road trips, but it is not the usual case.
Second, average age of car on the road is above 10 years in most countries; and those that drive old cars definitely do not have €26,500* spare to swap their EV's battery for a new one.
*That's what Audi charges here for e-tron 50 battery replacement, which are already starting to fail for many owners
By 10% over 10 years, assuming the worst case of nothing but ultra-fast charging. This seems minor.
Old cheaper cars could be 10% less convenient to use for very long trips. This should not shock anyone.
Rather than an expensive battery swap, sell it on at a lower price to someone who doesn't need 100% range.
From my personal family anecdotes: my mothers' 4 year old Hyundai Ioniq 5 had complete battery failure. Thankfully under warranty. And my fathers' 5 year old Audi e-tron 50 already has <80% range remaining, with very rare fast charging.
