I guess "cells" is one option. Or you could go old school and call them "accumulators"

"Electricty Container Thingies"? 😜

I'd go with super dense batteries. That would mean the cars would be lighter and much more fun to drive. It would also make ev restomodding much more easier and fun :)

Honestly it comes down to use case. In the UK, charging quick is good as you don't go too far in a trip. London to Glasgow is only 700km. Which from someone in the UK is a long way. So two stops is perfectly ok. You might only do that once every 5 years or so. In Canada Toronto to Montreal is 550km and that is a Derby Match. You might do that 3-4 times a year if you are a TFC supporter. Growing up we did 700-1800km to see my grandparents every summer. So for us we need at least some models that have High energy dense batteries that can do 450km+ on a charge. Ideally ones that can charge fairly fast. As because we do it so much our bodies are used to doing it without stopping. I recently did 430km in under 4 hours without stopping at all. The average person everywhere only needs 20kwh batteries for city driving (particularly for a second car) and they charge at home. The option for 450km+ range Spring to Fall is important for a lot of people though and those options on cars are needed.

You can refer to it as "the pack" ... short for battery pack.

whats c rate mate

Napkin math: 35 kWh battery charged at 350 kW would be a c-rate of about 10, which is a LOT. Napkin math 2: Fully charged battery in 6 minutes is 1/10 hour, so a c-rate of about 10. Which is still a lot. Yes, I assume you can do this math as well and it is far from the whole story, but ballpark numbers work for me. 😇Having a complete battery working in a car is also closer to real than a prototype cell in a lab. Time will tell where they can go with this.

​@@cameronsmith2928 its a practically useful but technically imprecise measure that tells you roughly how high the specific charging or discharging rate is. It's a more handy version of power density. For example a C-Rate of 10 C means: Charge power in KW = C-Rate × Capacity in KWh 350 kW = 10C × 35 kWh As you see, maximum charging power also depends on size. Throwing in tons of batteries is considered a bad trend. Reaching the same power with less batteries is technically more challenging. Discharge rates are typically higher, rimac's nervera tops out at 12,5C discharge rate, other cell chemistries reach 30C (like drone batteries) but those are less save, more expensive and don't last very long. That being said, i have yet to see reactions by proper battery scientists if there is something to this particular company because this topic is complex and often cells that excel in one measures have significant deficiencies in other measures. This is very likely and it's in the interest of a company searching for investors to be a bit secretive about this. The relevant measures are: longevity, safety, volumetric energy density, gravimetric energy density, power density, material availability and manufacturing simplicity. It's unlikely someone just stumbles over some tech that is better than current batteries in all meausers.

I’ve seen discharging at 10C, but charging at 10C is bonkers

@@cameronsmith2928 C is the charge rate, as measured by the current. Say the max output current of a battery is 5 amps at its rated voltage, then a 2C battery could charge at 2x5 = 10 amps.

Do they actually deliver 350kw? I've heard EV drivers moan about reduced charge speeds, especially when other cars are plugged in at the same site.

@@the_lost_navigator7266 they can go only deliver what the car can take. There aren't any cars yet that can charge at 350kw

I was puzzled by that comment as well. Many of the locations also have multiple 350kW charging units. If that “fact” can be so far out it weakens the rest of the video.

That's a business model problem

Good point. There is also the issue of having to stop frequently, which is more inconvenient. Just use a normal size battery with a range of 250 to 350 miles per charge.

@@toyotaprius79 A broken one.

Do you really nitpick on charging prices if you drive a sports car?

The future will be buy the battery you need and suffer the occasional. I suffer a 54kwh battery in an ioniq5 and it does 90% of my journeys. Posting for the 77kwh battery just did not seem worth it. With the weight and size saving I could see myself going down to a 48kwh, with this charging I could see my wife going down to a 20kwh battery.

@@kalmmonke5037 are you high?

why are they still mining for material to make electric car battery? because they cant recycle a small portion of it, they cant even claim to get it done which is why they re use the used up , thus low performance, battery by stacking many more of them together in order to have the same performance as those were able to make alone before, thats why they only use such stuff on non transport application,. batteries have low energy per weight, so the more battery you add, the exponentially less energy effceint it becomes because you arnt using the enegry of all those batteries your hauling around at a given moment of normal driving. this also worsens battery longveity because high rate of energy flow, although that can be balanced out with dividing the degradation of battery life among more battery cells... theres a balance to be made, and that balance is to be further balanced with the amount of battery raw material we have to use wherever it is most effective at reducing emissions, assuming thats even a need. so using batteries in non tranport is the most effective way to reduce emissions. weight causes tire wear suppsoedly endocrine disrupting microplastic emissions dust , altough tires could be made of more natural rubber and less petrol plastic like fisker claims they are doing, using considerably more natural rubber tree stuff is going to require less grip, that means a lot less car weight than we have today. weight is more harmful in a car crash, although it would be expensive to protect people inside by crash structures, high grip anti control loss sporty car dynamics, etc, , there is not much assurance of protection for others involved in crash. roads wear damage also becomes much worse due to more weight. CAFE laws are apparently written by people who dont care about emissions , which si why big tall vehicals are incentivized by making it hard to meet emissions stansds on lighter weight smaller vehicals , engines, etc, which wouldve also lowered emissions and raw materials use for sustainability of the raw materials economy. nucelar and electrolysis hydrogen are the only mainstream tech hope, yet those things are destoryed by the same people who push the climate crisis like world economic forum, ebcause they peopel dependent on petrol etc so they can threaten those who rebel against their will by taking away their energy etc. youtubers liek tony heller, tom nelson , and corbett report text series on substack website called "how balckrock conquered the world" , "gainign traction, loosing tread pollution from tire wear now 1850 time worse thanexhuast emissions" article by emissiosnanalytics website, look aroudn this youtube channel sort of thing at odysee sitge: VSOF Timeline Class: Lies and Thievery of 4000 years, the History of the Old-world order Anew. , orbett report text series on substack website called "how balckrock conquered the world" @@johnmeyer457

​@@poletooke4691Then cars with small battsries aren't for you but thy are for a lot of people.

For clarity where are you writing from, I rarely find an unsevicable DC charger (UK), but maybe I am lucky.

You are lucky. I’ve had my i3 REX since 2015. I used to regularly do a run from Berkshire to Lincolnshire to see family back then, and had to do a lot of the same runs last Summer. In seven years, it has become no better. Yes there are far more chargers, but there are also far more EVs. I’d estimate that over the many trips I did, I encountered a problem with either broken or restricted charge units around 30% of the time, and delays queuing of at least 30 minutes taking that up to about 50%. The only good change was that all the motorway charging units now take contactless payment. I had a few more trips this Spring, and I just ended up using the REX, rather than go through the hassle. I have always been a massive proponent of EVs, but this is still one of the biggest minus points in my opinion.

​@@markparker5585do you check ahead and try to go to a charging station that has available chargers? Or are they all fully in use? Is it simply the numbers?

Definitely but that type of improvement isn’t going to be on the horizon anytime soon. I think even solid state technology will be “only” a 2 or at most 3x density improvement (which would still be huge improvement).

You only need a battery that lasts as long as your bladder. If you need to stop every 2 hours for a pee that'll give you enough time to recharge your EV 😂

10x energy density would mean 10x longer charge when you do have to stop... bear in mind that you only have to charge more frequently with this vehicle because they decided to only put half the battery capacity in... if it was a 'normal' car with a 'standard' battery, you'd stop with the same frequency as a current vehicle - but for a shorter period (time for the loo?)

@@logicalChimp not really, because you’d need a much smaller battery to achieve the same results

@@stephenwensley9328 Sure - in which case, you stop as frequently as you do currently... just increasing energy density in order to stop/charge less frequently means it will take longer to charge when you do finally stop.

Agree, just a tad slower would be great, I was tempted to go to .75 speed just to separate the words a little.

This is a good point. If people have to queue that is clearly a failure to have enough chargers. Though if everyone could charge in 6 mins you wouldn't have to wait very long!

Not going into production says a lot. It’s not like other automakers can’t do the same.. they don’t though for a myriad of reasons. That said, I’d love to see even faster charge times, but not if it comes at the detrimental expense of longevity, reduced safety, higher cost, reduced range, and so forth. Reminds me of when overclocking computer chips used to be a thing , caveat being reduced longevity, complex cooling, higher cost, etc. While not a perfect analogy, there’s nearly always a compromise.. a trade off to absorb more energy in a shorter period of time. Discharging at high rates also has its own caveats. In any case, it’s been well known that faster charging is possible, but the immediate questions become; is it repeatable, for how many times, for how long, at what cost, with what trade offs, etc. When those can be addressed in a safe, commercial scale, automakers will incorporate this in production vehicles. Till then, it’s still just a fancy headline.

Maybe the Catherham V is an option

Be careful what you wish for.

JeremyRogers the simp

I think she said 350. And I think that's just the fastest charger available. Making the battery smaller doesn't make it charge faster, unless you are maxing out the charger. The cells get charged in parallel. You can have twice as many cells and it takes the same time to charge, as long as the charger has enough power. These are faster charging cells.

Simples: power is just the rate of delivery of energy. My junior physics teacher always used to say if you're getting lost, look at the units. Energy is in joules, power is in Watts, which is just another name for joules per second.

Power is literally the amount of energy delivered over time. That's it.

​@@gabedarrett1301it's also the other way around, energy is power over time.

You are not alone. Now that you understand, it is a curse, since you will notice youtubers mixing up kW nd kWh all the time. And you will want to hit your head against something hard when they say kW/h. Welcome to the club! 😅

@@geirmyrvagnes8718 in all fairness, better words/terms could have been created for this, to make it easier for non-technical people to not confuse them. On the other hand, hardly anyone mixes up speed (in km/hr) and distance (in km)...

And the range too

She's a little bit clever as well.

You've forgotten reality for most people. Average mileage is less than 50km /day (30m) in many countries, and so naturally a lot of people do less than that. 15kWh would be enough for these people. If you want to drive 500km to work I don't think anything I say could stop you, but please don't pretend everyone else has the same priorities as you.

kWh... not kW

Can't actually think of ANY non-Fanboi reason why we would need to remember that..... !?!?

Except that Tesla ruined it's handling

The shell, interior, and chassis aren’t in question. The safety and viability of this method of charging is. If it were, we’d see automakers already producing cars with this capability. Seem though that many hurdles remain and trade offs and consequences with charging so rapidly have yet to be mitigated.

@@andymccabe6712 I'm actually not at all a tesla fanboy but somewhat fascinatet by the Lotus way of going light with relatively small engines. This time they seem to have done a better job (than both Tesla and even Lotus!) do stay true to that philosophy.

@@justice4g generally no. of new cars, 80-90% Are EVs here. But almost all Are newer bigger 40k$ or higher. Not to say cheaper smalner evs dont exist, i know plenty of people that have 2 EVs. One smaller for whatever trips and work, and then one bigger family car for long distance trips. Usually the man in a relationship has this one :P

Half the reason I want an electric car is so I don’t have to ever go to a petrol station/charger... They also cost as much as petrol There’s is deffo a market for this but not for me

This is how I charge my EV on long journeys. A series of short charges while buying coffee etc. It works so well and I find my journeys are more relaxed than in my petrol station days. I'm loving having an EV and would never want to go back.

More wear and tear… which could be a concern

That sounds great. Unfortunately, anyone who has had to charge on a journey will tell you the infrastructure just isn’t there to support it. I drive a plug-in hybrid in Canada. Most chargers are hard to find, often in use by others or faulty. Fast charging also degrades the battery quicker, and the high currents involved increase the risk of fire Until chargers are as ubiquitous as gas stations I don’t see smaller batteries being popular

35kWh is around 150 miles in my e golf, so 100 seems light here

@@MrAdopado but only if you really practise sport mode at high speed the whole time - which doesn't occur always - even with a sports car.

@@reinelektrisch4997 Yes, of course but a sports car needs to be able to go out for an afternoon "spirited drive" and still be able to cover a useful range before recharging. The smaller pack being able to deliver full output at lower percentages would also be crucial ... but of course this company is making claims that this will be the case ... let's hope so if it ever gets into production!

The batteries that can charge at 250kW+ are all larger batteries (because bigger batteries charge faster, due to having more cells in parallel to accept the charge)...~35kWh battery packs typically cap out at 50-75 kW charging... and with a noticeable taper from peak (around 20%). If this 35kWh pack was charging at 350kW then that's already 4-7x faster, and if it doesn't taper (or at least, tapers less) then that could account for the difference.

Why stay with the car? Plug in, then go the loo, grab a coffee... when charging starts, the plug is locked to the vehicle, and can be unplugged until charging stops (if that's what you're concerned about)

@@logicalChimp That's my point - If it's only 6 minutes, I will have wait and move the car as I won't have time to do anything else. The average UK rest stop is 15-25 mins that's how long I ideally want to charge.

@@garyallsopp6369 Ahh - if you're meaning in terms of not blocking the charger once charged... personally, I'd still just go to the loo etc, but I tend to travel solo, so my stops are usually ~10 mins (and 'blocking' a charger for 2-3 mins isn't the worst crime :p)

When fast charging it gets very hot and cooling it down is the key to enabling fast charging. So, within reason, the cooler the faster, in normal conditions. If you did something crazy like cover the battery in liquid nitrogen it might degrade performance.

​@@adrianthoroughgood1191havent you heard of the nightmares of electric cars in winter?

@@bradhaines3142 that applies to when you leave the car parked out in the cold and not plugged in, and in a very cold place while driving. Charging is not a problem because modern electric cars have battery temperature management systems that can either heat or cool the battery as needed. When driving these have to be powered from the battery which reduces range, but when charging they are powered from the charger. If you drive to the charger and plug in straight away the battery will already be at a reasonable temperature. If you don't plug it in straight away, eg if you have to queue, the management system may have to heat the battery up first which makes charging take longer but it will be fine after that. Fast charging produces so much heat that even in a very cold climate it is likely that getting too hot would still be more of a problem than getting too cold, once it gets going. EVs work fine in a cold climate as long as you don't leave them unplugged for a long time. If you can have a charger installed at your home and work place then they work fine even in very cold temperatures. Most people can install a charger at home. If you can't then it may be best to let the people who can switch to EVs first and wait a few years for tech to improve and more public chargers to be installed. Especially if you live somewhere with very cold winters.

There's a tram in Australia that uses supercaps. When I saw footage of it with no wires at first I thought it was diesel, until I read that they recharge it at every stop with enough juice to take it to the next stop. Great system!

That depends on the battery formula. Almost all of them are optimized to a particular temperature.

Goldilocks. Not too hot, not too cold. Roughly body temperature is good.

​@@downix Really? Kindly explain.

Also: If you start charging at an ideal temperature, rapid charging in itself will add a lot of heat, so you will need cooling. A small percentage of 350 kW lost as heat in a contained box can get toasty quickly.

@@t1n4444 different chemical formulas react differently to different temperatures. For example, a Lithium Iron Phosphate battery gets optimal charging rates at around 10 degrees C, while Lithium Nickel Manganese Cobalt Oxide batteries (which you find in most Tesla) get optimal charging rates at around 25 degrees C.
