EV general discussion

@Nasher the cells are similar but not the same.

The BMS manages the packs very differently, the load is spread across a huge number of cells. They also don’t charge as high or discharge as deeply nor are they cycled anywhere as quickly as a laptop. They also have active thermal management so they don’t cook themselves (except the leaf). In phones and laptops batteries are sandwiched between the heat source and a case with no ventilation, they get hot, too hot. Batteries in phones and laptops are only designed to last 2-3 years so they can maximise life vs the life expectancy of the device.

Just think, average uk mileage is under 30 miles a day, a Tesla has 300+ miles range. 10 days to cycle it once, one year is 36.5 cycles, 1000 cycles is 27 years or 270,000 miles. 1000 cycles is conservative, many modern cells are rated way beyond this, most are 2k+
 
You are wasting your time, they will still be driving a fossil ICE car when we are all using flying vehicles powered by a Mr. Fusion. :D

Why don't you look at Prius forums. It's a hybrid but it still has battery tech, etc.

They have been around for ages and you should be able to see how many of them lasted over 10 years.

Yes and many of the older ones have dead hybrid systems. To costly to fix, so they stay dead and become a very inefficient 1.7 petrol.

When has the Prius ever had a 1.7 litre engine?

Regardless, the failure rate for Prius battery packs is incredibly low considering how many of them are on the road. We can only assume battery technology has come on leaps and bounds since the first mass produced Prius was introduced over 15 years ago.

Edit - also just to point out there are loads of independent garages that offer a full hybrid battery reconditioning service for the Prius for £300-500. It’s really not that costly even if the worst happens.

Just for a laugh, 200k miles at 50mpg with an average cost of £1.28 per litre would cost you £23,244, but fcharging an electric car with an efficiency of 4mpkWh, would only cost £7,500 at an averaged cost of 15p kWh. So only a saving of around £15,700, I'd rather spend the £15k on a new battery pack, than give it to oil companies to be fair.

yes. Those lithium mines are owned by nice people who care about the planet and people.

It’s only about 4% of Cobalt production and less and less cobalt is being used in batteries nowadays

And you can prove otherwise?

I think the onus of proof definitely sits in your court

With totaly clean mining methods and disposal :D

That’s right liquid fuel has its own disposable mechanism it’s turning liquid into gassiest emissions we just releasing the atmosphere without a second thought yeah?

And lithium turns in to a highly toxic gas (and fire) on contact with any moisture at all, even the small amount in the air.

That’s impressive I literally know of no 1.7 L hybrid cars!

Atkinson cycle engines are actually very efficient regardless

That’s why they get put in waterproof boxes it’s cute you think lithium is in used in its element form

Never if I can help it. I'm not opposed to getting an electric daily runaround but I'd still want an interesting petrol car or two on the side.

Are you planning in giving up driving in the future? I somehow doubt that internal combustion engines will remain the main form of propulsion in the next couple of decades.

Like I said, I'm not against having an electric car as my main car. But I will still want petrol cars for my hobby. They aren't going anywhere.

In a couple of decades EVs will cost as much to run as petrol cars, because the government won't want to lose that tax money. So old petrol cars might end up not costing all that much more to keep going :p
 
petrol is likely to become a specialist commodity at some point. Petrol stations are expensive to run, licence etc, so once the volume falls out of the market they are going to either have to charge a hell of a lot more, or just give up.
Refining, distribution, literally every thing thats now cheap will become more expensive as it becomes more niche. Companies will leave the market place and fewer companies will survive by price gouging with low volumes. It ain't going to be a cheap place to operate.

In the mean time, general public will moan about these silly old polluting cars holding everyone up ;)

Real rich people will be fine, they will probably have a tanker come round, top up the car collection.
