Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging::Typically, it takes around 10 hours to charge an electric vehicle. Even with fast-charging techniques, you’re still looking at a minimum of 30 minutes – and that’s if there’s an open spot at a charging station. If electric vehicles could charge as swiftly as we refill traditional gas vehicles, it wo

I asked gpt4 to explain this abstract in terms a high schooler would understand.

Sure, this text is talking about making better batteries. Right now, a type of material called “mixed transition metal oxides” has potential to be a really good component in batteries. But there are problems like they don’t hold as much energy as we’d like, they’re hard to make, and they don’t conduct electricity well.

So, the researchers made a new version of these materials, tweaking them with manganese and iron. They used a new, easier method to make super-thin sheets of this stuff. This new material can hold a lot of energy, way more than the old versions.

The thin sheets also let electric charges move more easily, which is good for battery performance. Plus, they made sure that the material doesn’t expand too much, which helps keep the battery stable over time.

So basically, they made a high-performance battery material that can be charged quickly, holds a lot of energy, and lasts a long time. It’s like creating a new recipe for a better, longer-lasting smartphone battery.

This thread is pure copium.

“Guys, go buy a more expensive car, but instead of taking 6 hours to get somewhere more now take an hour and a half. And if it’s a busy travel weekend maybe 3 hours. And don’t forget about the trip back.”

I’m all for EVs being successful but you all force feeding bullshit hand waving down people’s gullets ain’t helping.

The problem is you dismissing reality and inserting your insecurity onto electric cars.

Superchargers are a very big part of why Tesla is ahead of the curve, and you don’t charge 0-100, you charge 15-whatever you need to get where you’re going, which for my six hour drive was a 19 minute charge stop, where we watched Netflix, and I have the slowest charging Tesla.

No revolution is coming. Deal with it. But it’s also okay to have up to hour charges. Take a break, get some coffee and everything is fine. If you can sit 3h in traffic to work every day or sleep in front of the store on black friday so you can get 20% off on things you don’t need, you can sit every once in a while on long journeys. You need a break from driving anyway.

Imo the way things stand things are already good enough as they are.

we don’t need to double battery capacity/distance or even charging speeds, it’s a massive waste of resources that won’t benefit the vast majority of people.

from quick google

Every day, there are some 70 Million (M) worldwide driving trips. The average trip duration globally is 15 minutes long. The average trip distance globally is 15 Kilometers / 9.3 miles. The average speed globally is 30 km/h (or) 18.6 mph

so even if you have a 200km worst case scenario range on your EV, unless you are one of those people that are on the road a lot, it literally covers like 99% of your car usage.

Hyundai EVs charge with 350Kw, to 80% in like 15m which is perfectly fine for a longer roadtrip imo. I used to travel 200kms every two weeks and in most cases I took a rest half way through the 2 hour trip anyway to stretch.

if you are one of those guys that will come on and say you drive 500+kms every day and BEV is just unacceptable for you, well guess what, just get a fucking Hydrogen EV, pretty sure those can get up to 1000km ranges already which is more than my Diesel Hyundai.

Averages are useless. It does not matter if my car is fine most of the time, I’m not going to have a second car for when it is difficult or impossible.

Hydrogen is the other tech which makes quick refuelling possible, but there are not yet enough hydrogen refuelling stations to make them feasible for most drivers. And we don’t yet know if leaks can be controlled enough to make hydrogen a net positive for consumer applications.

so what, you would want to triple your battery capacity because once a year you might need it?

why not just a rent car for that one occasion?

Where did once a year come from? I can’t reach any of my family without stopping to charge most (currently affordable) EVs. We only bought a car because it was getting more expensive to rent them when needed (and train prices have doubled), we’re not going to pay twice over.

Have you rented a car for a week? It’s prohibitedly expensive for most people, especially if it needs to be big enough for the family and a week vacation. I’m considering getting an EV, but it’s only because we’ll have my wife’s gas powered SUV to use for our longer trips, which are 1-4 times a year. That not an unusual need, and one that make exclusive EVs a no-go for a lot of people. Hybrids are an option of course.

Average trip duration is not a great metric because they measure a trip as going from point A to point B. That’s great, but then I do six trips a day in errands.

Total miles per day is the metric to use. On average, in America, it’s 37 miles.

That is to say, EV cars would work for many people. But to reach the majority we need these advancements.

Because we’re talking averages. People don’t buy a car to go an average number of miles. People buy a car to cover the maximum number of miles that they would go.

Maybe I average 37 miles a day. But four of those trips are 8-hour drives to see my in-laws. I’m not doing that in my Nissan leaf.

I’m lucky enough to have two cars. My Nissan leaf which I use for everyday driving, and an ICE for the in-law trips and my spouse’s driving. If there were a vehicle with extended range, like 300 mi, and a very quick charge, I would get rid of the ICE. Until then, 50% of my cars are not EV.

Faster charging means a lower chance of all the chargers are in use at the service stations en-route. Currently if you’re in need of a charge you’ll have to wait for the others cars to get charged and then you still have the 20+ minute wait for your own car. That’s going to put a lot of folks off owning an EV. Coupled with the fact the EV uptake is growing a lot faster than the charging infrastructure to support it. Faster charging has a lot of benefits.

except, the vast majority of your trips are from your home to some place and back, you charge at home and the range is more than enough to cover 90+% of your trips.

rather than focusing on super chargers (which we also need along high ways) we need to focus on smaller lvl 2 chargers at places where they make sense, apartment complexes, offices, to enable BEV use for people who don’t own a home with their own garage.

you also completely ignore load balancing of the infrastructure, for one 350KW charger you can create 7 50KW chargers, that means 7 cars being charged while parked at places you spend lots of time at instead of 1 charger charging 1 car.

so like I said, fast chargers make sense next to main roads and highways during long trips and they don’t make much sense at all in cities.

This assumes everyone can have a charger at home. A large portion of people can’t. Apartments, associated spaces, on-road parking… a lot of people need public chargers.

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.

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.

That’s a very defensive response. You’re mocking the above poster because they “can’t deal with physics” but you seem to be neglecting biology yourself.

Driving something like 400km would take a good 4-6 hours depending on traffic. As a flesh and blood human you need to at least stop for the toilet, you should eat something to keep your energy levels up and you must always stay hydrated. Sure, you can power your body through that, but you can also power your body through 48 hours without sleep or an entire KFC bucket of chicken all to yourself - just because you can doesn’t mean you should or that it’s healthy. The difference in this case is that fatigue can lead to deaths, not just your own but whatever poor sucker you happened to drive into because you have been driving for 6 hours straight and lost concentration at just the wrong time.

Please do come back and claim that you don’t lose concentration and that you don’t need to stop every few hours because your reaction times and concentration levels are just fine. There isn’t a human on the planet that can make such a claim. Again: just because you can does not mean you should.

in the defense of the comment above, a chicken bucket would keep me full for 8 hours. and pissing would probably take 5 min or so. it could be less if a piss bottle is used and one needs to get to his destination quick and have no time to look for a destinantion restroom.

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.

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.

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.
