Never really understood this criticism of EVs . Surely there is far less to worry about than with a conventional vehicle? Yes the battery is more complicated, but compared to an internal combustion engine, with its oil, fuel rails, exhaust, water cooling, etc, an electric motor is a much simpler affair. And I wager easier to replace as a whole unit if it suffered a catastrophic failure. What other "unknown risks" are there that are unique to EVs? It's not like electric power is some huge mystery.

Spot on, the only component that is not similarly on costs or cheaper is the battery which is a very expensive component to go wrong(but this is similar to an engine breaking and needing replacing), however, most EV manufacturers have very good warranties/extended warranties on these.
People are weary because they haven't been around long enough to see how they last. We know the risks with petrol/diesel cars and know they can go on for 100,000s of miles and last decades if looked after. The biggest worry with EVs is the battery pack dying out of warranty, which is about the same cost as buying a new engine.
So why wouldn't that apply to an EV that is much simpler mechanically?
Electric motors existed for decades. They've been in use in much heavier applications that domestic vehicles. The only thing to worry about that you don't get with an ICE is the large battery, it I seem to remember reading that these are often guaranteed to outlast the usable life of the vehicle anyway. I'm not saying one shouldn't be cautious, but I dont get the irrational fear people have for the longevity of EVs.
The motors will last, but they aren't a hugely expensive part.
A lot of people like to claim batteries will last X duration, but I've lost count of the number of times that has not turned out to be true. From a car manufacturer especially it should be taken with a pinch of salt. We'll believe it when we see it

Can you share? I'm really interested the way EVs are advancing, I'd be interested in reading any long term experiences with battery longevity.
I've talking from general personal experience. Manufacturer claims batteries for a bit of equipment will last 5 years...1 year later batteries dead. History tells us batteries suck for longevity
Some examples would be good - I can't say i've come across many, if any, situations where i've encountered something with 20% of the claimed battery longevity
Laptops, phones, UPSs. Plus pretty much anything left in storage for a while and left to discharge.
Nor I. Conversely, here's a link to a some real life experiences of battery longevity in Teslas:
https://www.google.co.uk/amp/s/www.teslarati.com/how-long-will-tesla-battery-last-degradation/amp/
One example there on 360,000km with 93% of the original charge remaining. How many people are still running ICE vehicles with that mileage?
You've had phones and laptops that are at 20% capacity after a year? With all due respect, that just sounds like you're talking ****.
An automobile isn't something you use a few times then throw in a draw for a few years though is it?
What, Nasher? Never!
No I'm talking batteries that have just failed completely...
So many of them you've lost count? I can't say i've encountered any batteries that are completely failed at a year old either. Perhaps you just mistreat your electronics?
I'm sure you'll get the odd one, just because they're not 100% reliable like anything else in life.

We deal with a lot of equipment, it's not common but it happens. Only last week we had a UPS battery literately go up in smoke. Would you take the risk of it happening in a car and needing 8k to replace them? That's the risk people don't want atm.

So nothing with a proper management or cooling system then?
Nasher is the Jeremy Clarkson of this forum: spouting absolute rubbish most of the time. The difference with Jeremy is that he's actually quite intelligent under the bluster. Not much evidence of that here.
He's already ruined this thread.

In 8 years where the only trend is the far higher duty of hybrids suggests there are no issues.
People need to ignore throw away devices and their battery life ie drills, laptops, toothbrushes.
