The Future Of EV Batteries Is Really Rather Exciting

[@MultiEski]

some people still think all modern car use battery same as we had in Nokia 3310 :)

[@Jaw0lf]

Great one Dave, advancements will keep on moving us forwards. My latest iPhone now uses ideas from the EV world and as standard charges to 80% but every now and then for calibration, it does the 100% top up.

[@paulbuckingham15]

I generally charge my phone (Note 10+) to 85% by using the setting that limits it to that. On a long day out I charge up to a 100%.

[@apollodeancampbell4272]

Advances in solid stare double density will increase ranges to 1000 miles on a single charge, and sodium will be massively cheaper and non flammable, these are places petrol and diesel have never reached, and never will. Oil is still the dirtiest business in the world.

[@foppo101]

Thanks again David good information and onwards we move.

[@rico4229]

Don't categorise Sodium Ion as just for cheap low mileage cars , the best of the current tech is about the same as current LFP batteries , which give decent range. Plus cold temps do not have as much impact on Sodium Ion batteries, which will offset the lower energy density. As for the near future. Solid State Sodium Ion is getting closer to production which will give higher energy density than current best in class Li on batteries. As you say Dave , the future is very exciting...

[@brendansheehan7714]

If I was starting out on my career today I would go into battery tech. It is so interesting.

As long as batteries can produce the currents required to power an EV, fire will also be an issue from short circuits in the electrical systems of EVs…..most ICE car fires are not caused by the fuel but by electrical faults. Interiors and aluminium burn quite well once a fire is started by the heat from an electrical short circuit.

[@ouethojlkjn]

Each cell in a Tesla is thermal fused and the minute the heat increases beyond tolerance the fuse pops and the circuit is broken. However, this does not Ward against a short circuit in a severe impact or something similar. That most likely cause of internal combustion engine fires is the 12 V battery shorting.

[@brianbailey4565]

NMC batteries were the most commonly used in EVs last year. So of the EVs on the road today this type is probably still the majority.

[@ouethojlkjn]

I’m not so sure about that, but you might be right. Certainly in China there will be far more LFP and sodium batteries in their proliferation of cheaper EVs. Tesla, which is the biggest global seller uses NMC in their high-end all wheel drive and LFP in their standard range.

The key of rapid charging in about 5 minutes, quashes the USP for Hydrogen

[@Hickalum]

To charge an EV in 5 minutes would require a current of about 500 Amps with copper wire 2cm thick. Where are you gonna get that from ? An extension lead direct to hell might do it.

[@rogerphelps9939]

@@Hickalum If you can charge at a couple of kilovoltts that is easily manageable.

[@244col]

Kilovolt or megavolt charging is an insane idea. Yes it would charge quickly but how is that done exactly? Even fully trained electrical workers have limits of approach to insulated HV of metres depending on voltage level. This is law in Western countries. Regular people limit of approach distance is even more. EV charging in cages perhaps? It is concerning how little respect people now have towards electricity.

[@Hickalum]

@@rogerphelps9939 Maybe. I don’t know enough about transformers, except that they are very efficient. … Those little brick buildings that house the step down transformers between grid and local distribution come to mind though, with “Danger of Death” written all over them !

[@ouethojlkjn]

I am afraid there are many problems with hydrogen not least the venting issue. As the cryogenically frozen hydrogen warms up in ambient air, the car has to vent. So you lose range while you’re parked even on a cloudy day.

[@oliver90owner]

I would guess that in the future the EV platform vehicles will likely mean more choice of cell type. I might expect that my car, if it needed a fresh battery in another ten to fifteen years, might get a different chemistry/ capacity/ charge-rate , etc cells rather than the present chemistry (NMC). The present EVs on ICE platforms are less likely to be quite so easily accommodated with up-graded batteries in the distant future.

[@peterjones6640]

The KZbin Just have a think has recently done a programme on battery development and how far away they are from commercial application according to a report from the Fraunhofer Institute.

[@andycotton162]

Yes I watched that too and my take from that, was that we are many years away from an improvement in car batteries, but nearer to static storage battery systems.

[@livingladolcevita7318]

After your recent vlog I saw yet another news report about charging cables being cut and stolen not sure where though

[@apollodeancampbell4272]

[@georgethompson453]

So best to let the technology improve and wait to what’s available in say 5 years time, in other words don’t plough your money into an EV yet. We get your message Dave.

[@ouethojlkjn]

Not a simple as that the early adopters pay more but save more. You are going on the assumption that electric vehicles cost as much to run and maintain as their ice equivalents

[@tobycolin6271]

This is another reason EV adoption is slowing. The whole of the car industry is suffering from Cuba syndrome. People won’t replace their current ICE because the future is so uncertain.

[@paulbuckingham15]

EV sales are increasing for both new and used sales.

@@paulbuckingham15 they are not increasing at anywhere near the pace expected. Adoption outside of the early adopters and heavily subsidised company car market is very slow. We are still bumping along around 15% and nowhere near the 20% government target even with the heavily discounted new cars available (up to 40%)

[@Burz69]

We'll never have an EV that charges in 5 minutes because you wouldnt lift the charge cable, assuming it is possible to deliver the power. Charging speed will ultimately always be limited by the charger.

[@Hickalum]

Correct … You would need 500 amps to charge an EV in 5 minutes … with copper 2cm in diameter. Unless … You could charge at 400,000 volts - then you need less than half an amp. So it’s very simple; just plug your car straight into the national grid.

[@rogerphelps9939]

No. You can increase the charging voltage by temporarily reconfiguring batteries from parallel tto series connnection. 800 volts is already possible with the EV6.

[@ouethojlkjn]

Cables can be liquid cooled. People managed to do without their iPhones for a couple of hours I’m sure even 15 minute wait isn’t the end of the world?!

[@NineLayerNige]

Gotta get the battery weight down

[@MrGMawson2438]

Hello mate

[@mbak7801]

WOW you cannot have it both ways. EV batteries were sold as lasting as long as the car. There are millions of non LFP batteries out there and if the statement about battery longevity is true they will be there for decades ahead. These batteries were also supposed to be used for home storage (please don't do that). Then you state that most cars now have LFP batteries. Absolutely not. Only the standard range Tesla 3 and S uses them. Other models do not which is also true for the vast majority of other EVs produced, especially the very low cost models. LFP batteries are very heavy and best suited for trucks and large cars. Sodium batteries are I believe only in one EV at the moment. Contracts will have to run their course so they will take a while to catch on. The old chemistries have a good while to run yet.

[@ziggarillo]

Nonsense

[@Burz69]

Odd. All MGs are LFP as are most other more recent EVs. I don't recall MG making trucks. Maybe I'm looking at mine from too far away?

[@bordersw1239]

@@Burz69. Incorrect, only the MG4 standard range has the LFP at present.

20 times less frequently tthan ICE cars.

[@apollodeancampbell4272]

The AA research into the subject from across the world suggests that the inverse is true; that EVs are far less likely to catch fire than internal combustion engine (ice). EVs have broken every road safety record on the grid. Bedfordshire Fire and Rescue Service records, some 1898 fires in 2022 were from petrol and diesel vehicles and 54 were from EVs. The Swedish Civil Contingencies Agency (MSB) reported 23 fires in 611,000 EVs during 2022, or 0.004 per cent in a year, which makes it 20 times less likely to happen than ICE car fires, which burned 3,400 times in 4.4 million cars, or 0.08 per cent. MSB has also recently proven a new way to extinguish battery fires fast.
