Reply to comment by SemanticTriangle in A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today by Wagamaga
I feel like this is one of the big breakthroughs people have been looking for in electric manufacturing. Off the bat this is going to be sold at a costly markup but once production evens out then potentially it would become the norm for electric vehicles and at that point yes, but the question is now who wants to be part of that initial round of consumer product testers?

And if it does scale up would quite literally make fossle fuel power obsolite as wind solar has the potential to constantly power and store entergy.

Nah, the blocking issues for renewable / battery combinations isn't having a limited charge rate, it's having limited total capacity, and a high cost per kWh of capacity. Although if this allows a more rapid discharge rate it might help with handling peak loads, which would make the grid more efficient

Hell yeah, ao it might take awhile but it’s something to be excited about!

No, it doesn't. No one wants a light duty truck that weighs 9000lb and needs to be recharged once an hour or thereabouts just so they can tow their work or travel trailer. It's going to be a while before EV's are the solution for all things transportation related.
The most important innovations are going to be weight and size reductions. EV batteries are fat pigs taking up a lot of space and adding tons of weight.
The F150 lightning weighs 600lb more than my similarly equipped truck, but can only go for an hour and a half with a trailer. That's just not an option when an ICE driveline will give you over 4 hours with that same load between refills.

Good thing everyday people dont need super duty road queens and just use small cars for transport. Just because its got little utility for one industry doesnt mean it wont solve a problem in another.

Yeah towing and hauling are going to be the last places that electric overtakes ICE's. But they'll likely get there eventually.
bigflamingtaco t1_is5naga wrote
I agree, it's just not going to happen by 2025 or even 2035. Most of the amazing improvements to batteries that get announced take at least a decade to put into use, when they don't come up against conflicts that prevent them from making it to market, like an inability to scale and bring the cost down.
We've also got some infrastructure woes that need to be resolved. The amount of throughput needed to have corner electric stations that can recharge vehicles like they fill gas tanks is insane, almost no cities have anything close to that kind of power capability, and we know infrastructure takes forever to get updated. Even if everyone were to sign contracts right now, there aren't enough works to make all the components and to install everything within a decade.
EV's are advancing at a great pace, but ICE is still going to be around for some time.

Yikes didn’t know it was that dramatic. Luckily battery tech will keep incrementally gaining. This is why a lot of people are way too (soon) optimistic. It’s the future yes. But we’ll play it like the internet. 1995 internet to 2022 internet wasn’t overnight . But I’m sure going from 2015-2035 will be similar for electric vehicles. Isn’t density increasing about 5% a year. It adds up. And I don’t know if that 5% is accurate. Up or down.
Anyways I didn’t know the hauling was that poor on the lightning. Maybe the big semi’s can make it work sooner?

Yep, the energy density of batteries is a long way from hydrocarbons, where most of your reactant can be pulled from the atmosphere on demand. To some degree you save some weight on drivetrain and ICE, which can go into a bigger battery, but you get a lot better range increase by upsizing a gas tank than a battery.

I guess we better give up then since this one part of many hasn't been solved yet. Then the example is "my decades-tested ICE vehicle lasts longer than one of the first EV trucks ever on the market". Yeah.

With the extended range battery it's almost 3 hours towing

Towing... a utility trailer with a lawnmower in it?
Check out TFL's tests on YouTube. You aren't getting 3hrs of towing on the extended battery with anything but a small trailer. Their larger trailer cut it to 150 miles. If you're dragging a travel trailer through the wind, will probably see 100-120 miles.

I read a review by insideev's where they towed a campervan, that's where the number came from, that may be better aerodynamically though, apparently weight is not such an issue, but simply enclosing a trailer then would give enourmous range benefits
bigflamingtaco t1_iscttde wrote
If you can find that, I'd appreciate a link, didn't see anything on their website.
Geeky Schmidt towed a small Airstream camper, and it cut his range in half. Unfortunately, that's not the typical camper as those things are ridiculously expensive, and they also sit low to the ground, which limits where you can go with them.
I average 20mpg unloaded, 10mpg with a 7ft wide cargo trailer. Although I wouldn't tow a camper at 70mph like in the above situations, a typical hard side camper is 8-8.5ft wide and sits about two feet higher at the roof. At 60 mph, it's also going to cut the range in half, or worse, depending on the trailers actual dimensions and amount of junk attached to the exterior.
Camp-inn did an aero study of their teardrops and found their trailer that curves at the corner side walls in the front cuts through air better than the traditional teardrop style of cutting at the top and bottom. Probably has to do with how the air becomes turbulent exiting the sides of the vehicle's. Would like to see more mfg's try alternate designs for better aero, including stuff like lower skirts and those things the truckers put on the rear of their trailers.

Now when are electric vehicles going to be actually equally as affordable to the gas only models so that those of us living on a low income as low wage workers can afford an electric vehicle as a daily driver for work commutes

It takes time, at one point horse and buggy was way cheaper than automobiles. The more adoption, the cheaper the cost. We gotta start somewhere.
dmglakewood t1_is72krw wrote
A quick search shows a nice (non-ac) fiberglass buggy costs 7,000$ and a Standardbred race horse (whatever that means) is 3,000$. The harness is another 500$. So all in you're at 10,500$. The average new car price in the US is 47,000$. So it seems as though horse and buggy is still way cheaper than an automobile. I'm not sure that your example works well in this situation.
madd0cc t1_is7i3tp wrote
Sure you're right but what I meant is that while a car is still more expensive than horse and buggy, you still choose the car. You're paying for convenience or practicality of the times. Meaning you don't have to take care of a horse and you get more distance out of a car than a horse, etc. Also I'm sure the differential between a car and horse at that time period was way larger than it was today. Not to mention, you'd have to adjust for inflation, standards of living, etc. You can do the math but I'm not disagreeing that they should cost less.
I think electric cars should cost less than ICE car. There's way less parts but with raw materials market the way they are now, not sure what's going to happen. Almost all the manufacturers are supposed to release cheaper electric cars but they keep adjusting the price with the damn subsidies the gov provides which is plain f'd up.

Question is whether or not this will become the next applicable tech for rechargeable batteries in general, and be viewed as the newest feature Samsung or Apple can use to push the next model. If so, there's your initial round of consumer product testers... or well, they'll probably do a ton of accelerated testing in-house of the tech, but you know what I mean.
pmmbok t1_is5rpe5 wrote
It says that quicker charging will allow for smaller batteries. But I don't want to stop to charge my battery every 125 miles, even if it's quick. So...but quick charging is definitely good. I am under the impression, perhaps wrong, that battery life is related to the number of charging cycles which would defeat some of the saving from using a smaller battery.
noiamholmstar t1_is6lkwq wrote
Adding a nickel foil layer is inevitably going to increase the size and weight of a battery cell, so they're arguing that you don't need as many cells because charging more often is not as big of a deal if each charge is shorter.
It's trying to frame the downside of their solution as less of a downside.
