The batteries cost too much to make and there isn\'t enough electricity to charge them all.
Why are they called BEVs? That\'s tautological. Of course batteries

That is not true. The car is very unlikely to explode if a single cell fails. Even if multiple cells fail an explosion is also extremely unlikely.
From the NTHSA report - \"Lithium-ion Battery Safety Issues for Electric and Plug-in Hybrid Vehicles\".

A cell can overheat under exceptional circumstances but a small cell may in actual fact be safer than larger ones as the energy of a single cell failure might be contained within its own steel container and not affect the rest of the battery to the point of failure. The fuse or other disconnect for the cell would electrically isolate the failed cell from the rest of the battery. If the cell breaches its own enclosure it could spread the failure to other cells.

Probably not - but the great majority of conventional vehicles don\'t
last that long either. The average lifetime of cars in the US is
about 15 years.
Accident damage or some major failure (such as engine!) often results
in a costly repair that causes it to be scrapped.
My last BMW was a great car until it was about 8 years old when
failures started to become annoying and expensive.

My Audi became annoying long before that. Admittedly it was a 100LS and
Volkswagen hadn\'t figured out front engine, front wheel drive, water
cooled vehicles yet.
I have found nothing but good things to say about Audis. Although they
are just VWs with a higher price tag.
One annoyance was the plug wires. At around 15k miles the car wouldn\'t
start. It didn\'t run rough or exhibit any problems until the day it
wouldn\'t go. I assumed an over zealous computer decided the wires were
out of spec. I always carried spares.
Then there was the day the wipers wouldn\'t turn off. I was in the middle
of nowhere and had to call the shop to find which relay to pull.
The finish had problems and the transaxles had problems eventually. My
wife got the Audi when we split and she traded it in on a Rabbit and got
almost nothing for it.
It certainly wasn\'t the car\'s fault but it wasn\'t geared to cruise at 55
when yet another idiot president passed a national speed limit.
Please don\'t tell me you agree with speed limits.
Not particularly but for the first year or so the cops were a real pain
in the ass with the 55 mph limit in the east. They\'d even set up rolling
roadblocks to keep people honest. There was also gas rationing in effect
which tended to make you more conscious of fuel consumption.
Eventually it got back to normal.

Many EV car companies are already using Lithium iron phosphate cathodes to avoid the need for cobalt and nickel.

It does. It\'s very toxic to mine.

No. A group of about 30-40 cells are connected in parallel. They are then monitored as if they were single larger cell as they all have the same voltage.
So one of those 30-40 cells shorts out, then what? It\'s getting fucking hot with the other 29-39 cells rapidly charging it, and there\'s no sensor on it? The other 29-39 look just fine, all is well, oops driver dead in a fireball.
In the case of Tesla they implement the bond wire from the cell to the common connection asa fusible link to protect against that eventuality.
I expect Rivian has a similar feature.
What actually happens is that most shorting failures occur within the body of the cell and the short itself gets cleared in a similar fashion to what happens in plastic film capacitors when a breakdown occurs. This would also apply to larger format cells.
Tell that to Rochard Hammond.
And to Ford Explorer owners.
Some time back Larkin pointed out, there is a huge amount of energy in the fuel storage of autos. While some people get upset by the 50 to 100 kWh stored in a BEV battery, there are up to TEN times that much energy held in a gas or diesel tank, 1 MWh! Yeah, as much as 400 kg of TNT.
If that is true, petrol cars should travel ten times further than electric.
If you could actually get all the energy to move the car, then yeah. But the efficiency of an ICE Is so horrible, it gets maybe a quarter of the energy turned into movement.
Do a little math and show me wrong. Use the massive gas tanks that are being discussed for the 600 mile range vehicles. You do know how to do math, right?
If electric cars are so efficient, why do they have such a shit range?

I\'m curious if you think you are actually having a conversation and how you expect him to respond.

The bottom line is lithium-ion batteries are proving to be very safe in BEVs.
So why can\'t I post you some 18650 cells in the post?
UPS Airlines Flight 6, etc.

That is not true. The car is very unlikely to explode if a single cell fails. Even if multiple cells fail an explosion is also extremely unlikely.
From the NTHSA report - \"Lithium-ion Battery Safety Issues for Electric and Plug-in Hybrid Vehicles\".
\"Regarding the risk of electrochemical failure, the report concludes that the propensity and severity of fires and explosions from the accidental ignition of flammable electrolytic solvents used in Li-ion battery systems are anticipated to be somewhat comparable to or perhaps slightly less than those for gasoline or diesel vehicular fuels.\"

A cell can overheat under exceptional circumstances but a small cell may in actual fact be safer than larger ones as the energy of a single cell failure might be contained within its own steel container and not affect the rest of the battery to the point of failure. The fuse or other disconnect for the cell would electrically isolate the failed cell from the rest of the battery. If the cell breaches its own enclosure it could spread the failure to other cells.

They can \"anticipate\" until the cows come home. What that boils down to is an uneducated guess. Until you have decades of data to analyze you are just blowing smoke. Just look at airline accidents; the B747 had decades of flight experience when TWA flight 800 exploded. And these planes undergo far more rigorous testing and evaluation than EVs do.
You would seem to be blowing smoke as much as anyone. In the case of TWA flight 800, a fatal airliner accident due to design or construction issues is a very infrequent thing. These causes are much easier to minimize failure rates than the operational issues.

Why does the Royal Mail ban batteries in the post?
they are chicken mostly.
Today the electric cars are the quickest on the road.
The classic petrol muscle cars are vying for the silver medal.
Was it obvious to the designers, from day one,
that this would be the case? Is it simply a power/weight calculation?
I\'m congenitally leery of simple explanations -
You said \"minors\" meaning young people, nothing about mining.
OCD fuckwit. I actually spelt it like that for a laugh, making fun of our fucked up language. Anyway minors are more fun than miners.
And most Lithium is \"mined\" using brine extraction, it does not involve digging holes.

So presumably they\'ll be banning electric cars from ferries, channel tunnel etc.

Conventional vehicles are more likely to catch fire than battery electric vehicles.
