How about milk floats......We all know EVs are just like them

Maybe towing a ForkLift.

Yes, Yes they can only do that due to the way an A/C motor works, now put a trailer on it, load it up 7 tonnes and see how long the battery lasts, the systems in there are exactly the same, yet designed to a different job, milk floats were D/C with lead acid batteries, so no comparison

I haven't finished with it yet, it'll have a lot more on it than that when it goes back, try a full charge from flat to full 5 days a week and see how long the battery lasts
I think EVs will be halling 7 tons pretty soon.

So you state EVs packs will fail after 110k miles, I show you real life evidence that proves otherwise.
You now want to know about charging, there are UK Taxi companies now running only EVs.
Any other anti EV myth you want busting?

What is it about the battery on EV cars that makes them so expensive.
I'm curious, is it the difficulty in making them, the materials in them? What makes them so expensive?
I'm sure increased manufacturing volumes will lower the cost but this will only be the manufacturing part not the materials.

And with the Govt. 'trying to encourage us' to use cars less, outside Norwich, houses are currently going up like mushrooms on vast new estates with no infrastructure. Thus to get to any decent sized shops etc. will require a car - !

EV batteries are made up of hundreds of pen cells, similar in size to AA or AAA.
Each cell is relatively costly, and they all need to be reliably wired in series and parallel to get the desired voltage.
All of which makes the EV battery as a whole expensive.

Initially it was production costs, hence why cheaper EVs in 2015 came with very small sub 30kWh packs.
Now prices remain high because manufacturers have to recover R&D + investment costs.
Battery+motor manufacturing lines are totally different traditional lines so you need to retool and retrain.
However some brands like Hyundai/MG are willing to sell their EVs at near cost neutral/no profit to get market share.
Where as brands like Tesla/Porsche are trying to hit high profit margins. Our Tesla cost £75k in 2016, the same car today is nearly £100k. The car today has a bigger battery but no where near £25k worth- more like £5k, but Tesla need profit so are willing to test the market at high margin prices.
Overall though battery production globally is still limited and EV demand is out stripping supply, so prices aren't likely to come down any time soon
.These things may look like normal AA cells or pouch packs found in consumer electronics but their manufacturing and management/building of the packs are far more complicated.
Car battery packs are designed to survive crashes, fires, deliver discharge and recharge rates no bog standard non EV cell can dream about. As I've mentioned these cells can discharge their entire power content at 5C+ than recharge at 3C, which is crazy amount of energy transfer.
This is how much energy they contain, and how reactive the lithium is, and what happens if it all goes wrong!!

Because of their high construction quality EV packs from crashed/written off cars are worth a pretty penny!!
When I had my first EV written off a few years ago, the battery pack appeared on eBay within 48hrs of me confirming with my insurers I was 'happy' to accept the settlement deal offered and released the car to the insurance company!!
I wonder at what point the cost of the battery will come down?
At the moment I can't say I'd feel comfortable buying an elderly EV from a non franchised dealer or privately. As the battery is the heart of the car you'd need to know it's condition.
I've always bought cars privately and know enough about what to look out for.
EV's are something for the specialist.

I wouldn't buy a used EV full stop. As you say unless you guarantee the previous owner has treated the pack with reasonable care you have no idea what you are letting your self in for.
Even BMS software can be tricked to show fake readings.....Not proven but people have bought EVs from branded main dealers with that looked like 'good' battery packs only to find massive degredation a few months later. They go back to the dealer who shrugs their shoulders and point out when they sold the car every thing looked good, so tough luck. Its essentially the same as clocking a high milage combustion car.
