General Motors built an ignition switch for decades which worked mostly just fine. Then they built one so crappy that they killed a bunch of people. Only to save 25 cents or whatever.
EVs depend heavily on 'early adopter evangelism'. I wouldn't read too much into this.
Today the market share for EV's is 98% and they account for the majority of the total number of cars on the road! The people who bough 1st. generation EV's as a number two car a decade ago chose EV's as their main car before long. My own vehicles are 7 and 12 years old and holding up well, despite the 12 year old having inferior battery chemistry compared to modern cars.
Change isn't always easy or smooth, but this one is inevitable.
The myths are now strong and it will indeed take a long time to dispel them.
I haven’t experienced this for years.
There are also some elements of EV ownership where they require some TLC, like not overcharging them when doing mostly local journeys, not using rapid charging more than necessary etc. If manufacturers were carrying the can it would be easy to let these things go out of the window.
This has grown to 6 in the meantime. It seems that the segment was growing even before Hormuz, propaganda or no.
In any case battery failure seems rare but it still is catastrophic and nobody can afford replacement. Hence companies should just provide some sort of warranty / insurance product for the few unlucky folks. Seems like an ideal candidate.
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 movement of used cars.
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.
"A 2015 Model S with over 265,000 miles on the original battery (85% capacity remaining)"
The implication being that runs counter to the claim of "calendar age degradation".
Usually you would think that 25000 miles per year over 11 years would degrade the battery faster than the car just sitting around for 11 years.
Source?
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.
They've been sitting unused, in their original packaging, never opened... They're still sitting at the charge they shipped at, but the capacity is so diminished that one can't even run an esp32 for a day. I've tried cycling them to see if I can get the capacity back up, but I think they're toast already.
I suspect the RC plane batteries you've been using for five years are not the same chemically as the EV car batteries in use in the UK for five years.
