What a bullshit article. While better anode materials are always nice, these claims about charging speed are just dumb. That's only so much power you can push into a battery and today's 350 KW chargers are probably already the practical limit. And if you can't take a 20 minute break every 400 km or so, you should go home and rethink your life.
I was thinking that this is one of those thousands of battery technologies we will never hear about again.
yea, charging speed probably capped by anode chemistry. would splitting the pack by multiple BMS's help circumvent this? if the charging time is the limit, people who prefer to drive 800km at a time could use an extra battery pack. that way a 20 min could be justified for them lol also we all know that it wont be 400km per charge. it would be only 330km at best.
That's literally the law in many countries - commercial drivers (who are the kinds of people who would be driving those kinds of distances) have to take a 45 minute break every 4.5 hours. Because it's unsafe to not do so.
That's a weak ass road trip. My car gets 400 miles per tank and we don't stop until it needs gas again. 400km is chump change on American roads.
That's very reckless of you. Regular breaks are required to be able to drive safely. If you don't take breaks you are being irresponsible and endangering your own life and those of others.
Jesus Christ lolol, Imagine attacking people because they don't want to spend an half hour or more waiting on charging.
Poor baby can't deal with physics so you lash out and pretend like waiting wasting hours on longer trips.
If you're going on a long trip and don't want to wait for charging, there are plenty of gas-powered options available to you.
thats no argument if u want the car to be mass adopted. not everyone lives in california, or the netherlands.
If you have ICE cars to rent for the rare trips longer than the distance the car can travel on one charge, not many will be on the roads.
the point of using EVs is to phase out ICE cars, not to make them rarer to use.Current EVs are still unreliable to achieve this, since the manufecturer is not running a charity and wants to turn a profit on those by cheapning out on battery capacity, ie Tesla. Fossil is a finite ressource. Also Once they produce a car that has at least double the battery size and costs only 30k$ that i would use for the next 50 years, then my purchase of those could be justified. i plan on buying only a single car in my lifetime.
Basically nobody does this.
not because nobody does this, it means that it should be the norm. also try to point out something more of material than this. 50 years probably, is too much. 30 years is reasonable (a car of 40 years ago still runs fine, as long as the body isnt corroded and the mechanics work fine. Power steering and is critical thou. the only thing that would prohibit a car from being used is the chassis, the rest is just parts) this is not an iphone that i should be tossing around each year.
At some point, like with every car, it gets cheaper to replace it than keep fixing it. Also, there is no way car companies are going to make a car that lasts 30 years.
a lot of reliable car brands like Mercedes did it, but they knew their cars were too good and lobbied for legislation that oblige people to replace their cars each 8 years. then come the emission laws. why would i pay 40k$ for a 75kwh battery car ? at least make it 150kwh for the same price. i also dont need digital screens everwhere.
No they didn't. There are no Mercedes brands that last for 30 years, except for individuals who take very special care of them. That's absolute nonsense. And why should they make it 150kwh for the same price if people are willing to pay more? I don't think you understand how capitalism works. And, like it or not, this world is mostly capitalist.
so u like to pay more for a thing that isn't worth its price 🤡 ? idk about u but either way i dont like to be cucked by overpaying for stuff that aren't worth the exact amount + a reasonable amount of profit. i didnt bring up capitalism but u did, and yea i hate it
It doesn't matter what I'd like. The world doesn't revolve around what I like or what you like. So if you want a car, it won't last 30 years and you'll be paying premiums for features you want. That's just how the world works. I'm sorry you want it to work differently, but there's no incentive for car companies to change what works for them.
why a car shouldnt last 30 years ? if u avoid driving it in salt to avoid chassis corrosion and not overall crash it, the rest should stay the same: glass is glass, tires will always be tires, and the rest is just oem parts, that could be either manufactured by oem or outsourced to thrid party to support the car platform. else replacing cars each 10 years is a massive waste (especially from an energy standpoint: the amount of energy needed to smolder the iron and cast it, wielding, etc.., quick disposal of cars isn't eco friendly really)
Because companies want you to buy more cars. They don't care about waste or being eco-friendly. Why would they? They care about making money. None of what you are suggesting makes them more money. It would make them less.
man if an EV isnt supposed to be eco friendly idk what should be.. Humanity isn't eco friendly either..Boy Elon want to turn a profit on his toy cars, why not ? at least price them fairly or dont produce low specced products. If anything, consolidating traffic by using public transport like busses and trains is really whats good for the environment. but sometimes one wants to indulge in a private ride without the noise and the bustle. anyway..
Do you really think Elon Musk cares about the environment? Do you think he wants his cars to last 30 years or less than 10? Which will allow him to sell more cars?
no one would want that. but anyway i wont be buying a tesla anytime soon. glad the chinese are catching up. they would gladly build reliable cars that would last, especially when multiple manufacturers start competing over markets. europeans are still stuck for now. with enough manufacturers there will be cars that last 30 years..but for now its only Elon's playground
And where did I say anything to the contrary?
I addressed the asshole attacking individuals who will use that option.
Really though, if you're reaching the end of your battery capacity with a lot of EVs out there today, you've probably been driving for about 3-4 hours or so, if not longer, the general recommendations I've seen are you should really stop and get a 15 minute break about every 2 hours to stretch your legs, prevent fatigue, increase alertness, etc.so that's pretty much in line with the recommendations. I know that's pretty much the rhythm I and most other people I've ridden with tend to fall into on road trips without even trying. And very often despite my best efforts, rest stops tend to end up lasting around a half hour anyway because of checkout or bathroom lines, or one of my travel companions taking their time ordering food or getting distracted somewhere.
I get that some people can just power through much longer drives, and I've occasionally done it, but honestly it's probably for the best if people are made to stop every couple hours and hit the reset button on their brains, a lot of people are shitty enough drivers when they're fresh and well-rested, let alone after theyve been screaming down the interstate at 70mph for hours, and their brain is getting fatigued.
It's double the recommendation in a best case scenario. It's 4x as long a wait if you have to get in a queue.
I've never had a rest stop that takes more than 10 minutes and that's if I have my toddler and wife.
If you want to stay forcing some drive time limits on people go ahead and try. But saying YOU get tired so everyone else must only be able to handle 2 hours at a time is insane. I'd be far far more tired showing up to my destination after an extra hour or two off driving and probably getting dark at that time.
I call BS. I have given diaper changes to my kids on the road that take more than 10 minutes. I won’t even mention lunch breaks, dinner breaks mid morning snack breaks, pooping breaks etc.
Diaper changes are a 45 second affair, 3 minutes if its a mess, and we're past that personally. We're in and out for toilets and have our own food packed. I commonly don't need to use the rest room and the wife will take care of everything while I hang out at the pump and pick her up. 5 minutes.
Not everyone lolygags around
true. resting each 2-4 hours is nonsense. a solid 8 hour drive and u get to sleep at ur own regular bed time beats them all. Evs need double the mileage (thus double the battery capacity and charging speed) so they could achieve this. other than that, it is just a car for vegans.
how about you recognize that your use case is very much in the minority and covered by alternative solutions like Hydrogenation powered cars?
sure you might want a car with 1000 km range and you can get that along with semi-trucks you can hop on the Hydrogen platform , but statistics show that the vast majority of driving people do is well within the ranges of current BEVs, so why make all cars carry around all that extra weight, the expensive batteries when the vast majority of it won't ever be used?
hydrogen is costly: it requires 44kwh of electricity to produce 1kg of H2, and that translates to 80km of mileage. while a 100kwh electric battery give u 300km mileage. also how much does a battery cost: 100$/kwh, ie 10k$ for 100kwh pack. i would gladly pay an extra 10k$ to have double the battery size, if just companies stopped being greedy and implementing stupid features like fast 0-60 acceleration, that eats up on mileage, and snake oil regenerative braking, and aero trunk spoiler for extra 10km mileage, for the price tag of 1k$ or god knows how much..i would gladly ride my pack at 110kmh with no brutal accelerations, and it would get me to almost everywhere i go. i shouldnt be needing a separate car to access remote areas, or always have to be anxious about range. minority ? hmm, well not everyone lives in the G7 countries, so we dont have a supercharger in each 100km radius. probably there are 5 or 6 V1 tesla chargers in 150k km² surface area where i am now
da fuck.
How often do you go to these remote areas? how many of these areas are out of reach from you on a full charge?
except there is more cost to a double battery size than just money, look up how the metals are mined for these batteries.
Doesn't matter, it's gonna be used for semi-trucks anyway, it can be manufactured anywhere and solar energy is abundant so is water, much more abundant than what we use for the batteries we have at the moment.
you also have to start to factor in road wear if you start doubling battery capacity.
not a concrete answer
not much but, but people who really do would appreciate an electric 4WD, not a cybertruck gimmick. i meant by remote that there no supercharger in 400km radius in sight
They use carbon and LiFePo4: Lithium,metal, and phosphorus, which are abundant. no more child mined Cobalt with NMC cells, according to Musk at least..
sure bro. solar generation capacity is at 200w per m². u would need to cover whole Russias worth of land to produce sizeable amounts of hydrogen. also installing panels in the desert isn't effecient, their efficieny drops alot when they are at temps way beyond 26°c
always has been. doubled the capacity or not. road wear affects tires and brakes more most of the time. battery wears at 100k miles or so, i am not sure, so not frequently swapped afterall
by road wear I mean that if you start adding more and more weight it will significantly increase infrastructure costs of keeping the roads maintained
it's a fitting response to your non-conrete statement about regen braking.
Oh so it's not even you are arguing for, it's these mystical other people.
okay, what the fuck does a non-product like cybertruck has to do with anything?
Are there people like that? I am from Slovakia which doesn't have a great infrastructure and I don't believe there are even people like that here.
what the fuck does desert has to do with anything?
no you dont...
In the EU it's mandated by law to rest after a few hours of driving. You shouldn't be driving 9 hours continuously like ever.
This is not true for private citizens in their own cars.
Correct. But if you get in an accident after driving very long without a break, that will definitely be counted against you in court.
Hyundai EVs that use 350KW charging get to 80% in 15 minutes.
if you are in the very-very small percentage that needs faster fueling and more range you will have Hydrogen options.
Congratulations. That's the dumbest take I've read on social media in weeks. That's downright Reddit levels of stupidity. Why don't you slink off back into whatever hole you crawled out from?
No.
