In late 2022, I moved into a new semi-detached house in a small project of 33 such houses total. Back then, there was precisely 1 EV here, parked openly.
This has grown to 6 in the meantime. It seems that the segment was growing even before Hormuz, propaganda or no.

If batteries are actually lasting, then it's easy to counter the propaganda. Manufacturers simply need to make sure batteries are replaceable and offer guarantees that they'll be replaced on the manufacturer's dime if they degrade.

#34They still die by calendar age based degradation. High miles low years isn't interesting. We know that works well. They don't like talking about the calendar age degradation. Every article like this leaves that part out. It's annoying. Many articles have been written like this. Many more will be written yet. I guess there are still people out there who don't know that EVs are ideal for drivers who accumulate high mil…
If this is true it's interesting, as ICE cars typically prefer to be driven continuously at operating temperatures, rather than cold. This is why a high-mileage low-year car can actually have an engine in much better condition than low-mileage high year cars.

Not OP, but this talks about it: https://www.sciencedirect.com/science/article/pii/S2352152X2...
That article says calendar ageing was the dominant ageing mechanism for batteries in their test vehicle, because said vehicle spent 96% of its life stationary. Unless I'm missing it, the article doesn't put a number figure on the rate of calendar ageing.
Real-world observations suggest batteries are likely to be serviceable for around 20 years, which is around the same lifetime of an average ICE car. Users who can tolerate a much reduced range (which is most of us) can likely extend this even further.

#36Isn't this old news? I remember reading about 7yo teslas used exclusively in cold climates (Norway, Finland, etc) and they found the same thing: batteries held on much better than even the manufacturer expected. And those were often 1st gen cars, which you could expect to have teething issues. It was at the time one of the main reasons the 2nd hand markets in those countries were pretty healthy and saw a lot of movem…
Some of the early models - either the Chevvy or Nissan Leaf - had battery packs which would degrade very quickly. This was causes by the charging system which seemed designed to destroy them.
The expectation in the EV fan world was that modern (> 2019) battery packs were very likely to retain 80% of their charge for well over the time anyone expected with the drop to 80% itself taking most of the car's expected lifetime. This was because the standard extrapolations ignored improvements in charging algorithms and that real-world usages were expected to be better for the battery than the models.
Another prediction we made is that range under cold (or very hot) weather would be significantly reduced and that seems to be the case too.

The black PR has been very effective. I own an EV and the first question I always get from non-EV people when they find out is "…but what about the range, isn't that a problem?", while the second one is invariably "but what about the battery, I heard it only lasts a year or two and it's so expensive to replace!".
The myths are now strong and it will indeed take a long time to dispel them.

the propaganda works because we are all familiar with the smartphone battery degradation after 2 years, so it seems logical that same thing will happen with car batteries
Re: EV Batteries Are Defying Expectations After Miles
#39No manufacturer is testing the batteries life by just charging and discharging them daily for a decade before releasing them. Instead they are using artificial acceleration techniques like getting the battery hot while charging/discharging continuously to simulate a longer lifetime. They can't realistically do anything else to estimate it. But it turns out heat is the big enemy for li-ion batteries and if you can kee…
we have EVs for almost 15 years now, one would imagine some real world data on battery life was collected already, even if not widely shared

I haven’t experienced this for years.
