As the US sabotages the globe's fossil fuel infrastructure, in China BYD's latest Blade batteries charge from 10–97% in nine minutes, and have a range of 1,000 km (640 miles). - Futurology Today

“BYD also claims to have addressed the well-known issue of lithium iron phosphate cells losing performance in cold temperatures. After the cells were stored for 24 hours at –30 degrees Celsius and therefore completely frozen, charging from 20 to 97 per cent reportedly took just twelve minutes.” As the US sabotages the globe’s fossil fuel infrastructure at the behest of Israel, China continues to build the future that will replace it. One by one, the naysayers’ objections to EVs melt away. Can’t do cold climates, they said - fixed. Can’t cope with long journeys, they said - fixed. As Napoleon once famously observed, ‘never interrupt your enemy while they’re making a mistake’. China must be thinking that, as the US helps hand it total dominance of the 21st century energy infrastructure. 10–97% in nine minutes: BYD presents second generation of Blade Battery [https://www.electrive.com/2026/03/05/10-97-in-nine-minutes-byd-presents-second-generation-of-blade-battery/]

Ok, so charging from 20 to 97% took 24h and twelve minutes.

Not really sure that is a huge win…

If this is some sort of joke I am confused why. Idk if you can’t ready but weirdly you don’t need to store the car in a -30c freezer for 24 before charging it every time. It was 12m from frozen, down from the normal 9m when not frozen, showing it being cold does not destroy charging performance (though that is 133% of the normal time)

No joke, that is exactly what they did according to the post.

They stored the batteries in minus -30c for 24h and charged them for 12 min.

The post made it seem like that was supposed to be a miracle hack to fast charging.

arctanthrope Mar 6

it’s a demonstration that they can still charge quickly in conditions that are bad for charging

TowardsTheFuture Mar 6

No… dude… they are saying at normal temperatures it fast charges from 10-97% in 9 minutes.

The frozen bit was them showing even completely frozen the fast charging still works in an acceptable amount of time. (12m, only a 33% increase in charge time)

Ah, finally a good explanation!

Thank you, I can see my mistake, sorry about that!

ThunderWhiskers Mar 6

You do understand the 24hr was the freezing process, after which they tested the battery’s charging capabilities?

Perfectly, but the post read as if they had discovered a new fast charging hack by freezing the batteries.

Which made it seem quite silly.

half_built_pyramids Mar 6

Not how I read it

Devadander Mar 6

You should work on your reading comprehension

Eh, it is fine for the most part, but I have a tendency to some times skip or add words when reading, had it since I was a small child.

It sometimes leads to annoying situations.

It’s clearly slower to charge when battery is cold. They had 20% to 97% take 12 minutes, while in normal conditions to took 9 minutes to charge from 10% to 97%.

Also notice that they actually bending the numbers a bit to make them look better, they started with 20% in winter and started with 10% normal weather.

So no, freezing does not give you an advantage when charging.

Storing batteries for 24 hours in -30C was to replicate a harsh winter time. It isn’t necessary for charging.

What the hell happened in this comment graveyard?

I missread the post, made a joke, people got mad, I doubled down, I got insulted, the issue was explained in another response, I admitted I was wrong, mods came in just as I had posted an explanation.

Eh, minor drama, though I am still annoyed about the insult.

Nice. Now the real question is how fast does the battery deteriorate. There is always a balance between speed, capactiy, and durability.

Seems like these batteries push more toward the speed and capacity side.

Seems like these batteries push more toward the speed and capacity side.

Why? What makes you say this? This skepticism seems unfounded.

BYD offers an industry-leading 8 year, 250,000km warranty. They are obviously confident about durability, and the proven durability of the gen1 battery is testament to their engineering prowess. The gen1 batteries are rated for 3000 to 4000 cycles. There’s a reason both Tesla and Caterpillar are starting to use BYD (finDreams) batteries.

Why? What makes you say this? This skepticism seems unfounded

Basic physics knowledge? Why would we disregard that based on the word of a corporation whose entire goal is to convince us to buy their products?

Warranties are a great way to build trust, but it’s still based on a promise, not the reality if the physical world. When a resource rich company wants to dominate a market, and push out competition, they will often promise these sorts of things to capture a market.

I won’t say that the technology isnt possible, or that they’re not providing… but going all in all at once based entirely on promises seems premature. And trying to shut down any potential criticism because of it seems suspect at best.

If you want people to trust in this, maybe engage with them instead of trying to shout them down.

If you want people to trust in this,

My point is not to run PR for BYD. I’m not trying to get people to trust a corporation. I’m just shutting down FUD (that is most likely rooted in sinophobia).

Basic physics knowledge? Why would we disregard that based on the word of a corporation whose entire goal is to convince us to buy their products?

Yes, I understand the basic physics since I am an electrical engineer and work in the automotive space, and I integrate batteries into battery electric vehicles.

Regardless of your stance on warranties, corporate competition, or China… the original claim was “Seems like these batteries push more toward the speed and capacity side.”

Where is the evidence to support this claim? For what reason could anyone think that BYD’s design philosophy caters to performance over durability?

This happens all too often:

An engineering feat is achieved
A layman hops into the discussion to inform everyone about the concept of engineering tradeoffs (as if that is groundbreaking)
The layman gives their uninformed opinion about why they think the tradeoff was ill considered

Here’s the simple truth: BYD’s entire battery design philosophy revolves around durability. If BYD was truly solely interested in battery density and charge speed, then why are they the primary champion of LFP batteries? If you were truly interested in performance and speed, LFP would be your last choice for battery chemistry. If anything, BYD leans more towards durability, safety, and longevity over performance - as is evidenced by their choice to make their entire design philosophy revolve around LFP. Teslas and Lucids lean towards Nickel Cobalt because Nickel Cobalt battery chemistry is fundamentally more performant than LFP batterys. THAT is “Basic Physics”.

So your refutation of skepticism is “you must be racist, so we should disregard this skepticism”?

You didn’t refute the physics or the claim, only showed that the company super promised they’d fix it if it went wrong.

If your background is in engineering, why didn’t you start from that instead of going into PR mode? It certainly seems more like damage control than alleviating actual concerns.

You’re not practicing actual skepticism, you’re just saying it’s probably bullshit while not knowing anything about it.

I would not be surprised if BYD is the industry leader and has the best battery technology, I just also wouldn’t be surprised if they are doing a showcase of the potential of the batteries if they sacrificed longevity. It is a claim by a company and isn’t verified by independent consumers.

Battery technology especially has a long history of performance with big astricks, so it’s good to be skeptical, even with industry leaders.

Being skeptical is well and good. Never did I say we should suspend our skepticism.

Seems like these batteries push more toward the speed and capacity side.

What evidence is there to support the idea that BYD intentionally designs more towards performance than durability? The fact that OP claims that the world’s champion of LFP designs more towards performance just shows how they’re talking straight out their ass, and have very little understanding of battery chemistry or engineering.

Never did I say we should suspend our skepticism.

This skepticism seems unfounded

Not explicitly, no, but you certainly implied it.

Please show me where I said we should suspend all skepticism about BYD.

It turns out that sometimes, general skepticism is warranted, but skepticism about specific engineering design choices that you are completely ignorant to, is not.

And further, “BYD designs more for performance over durability” is not skepticism. That is a concrete accusation that has no basis in reality.

Im not going to have a philosophical argument about when skepticism is allowed or not.

The original claim was: BYD intentionally designs for performance over durability. There is no reason anyone could think this other than sinophobia.

fuck you retard

Bombastic Mar 7

This is just absolutely wrong lmao

Can you say more about this? You seem confident and I’m curious.

It is quite simple. If you take the exact same technology, then it is some sort of a triangle between quality, speed and capacity. But saying that it always is like that is implying, that there are no technological advancements. Li-Ion, Li-Po, whatever materials you use, the products you use today are way better than 10 years ago.

Different technology. It’s like saying a boat last longer than a plane because it’s slower.

pricklypearbear Mar 6

Its lithium based battery. Not really a different technology. Its more of an improvement on the existing technology.

This is from improved tech, not from (un)balancing speed, capacity and disability. That idea doesn’t hold to improved technology.

justlemmyin Mar 6

And if you have the time, watch the latest technology connections video. Its long but worth it. Especially if you are from NA.

All the fear mongering about renewables and batteries is insane.

The amount of Facebook slop accounts about car batteries catching fire is mental. Petrol of course being famously non-flammable…

And if the blockage continues China will be unable to manufacture them.

Iran has made exceptions to the blockade for Russia and China, and now India.

Pommes_für_dein_Balg Mar 7

Why? It only blocks off the oil producing countries in Arabia, the way from China to the Suez Canal doesn’t go through it.

40% of China’s oil supply goes through Hormuz. Probably lots higher for LNG. Manufacturing and shipping will be severely affected.

Wait … so maybe this war is actually based?

Sodium_nitride Mar 6

If you aren’t being sarcastic, it’s not based because over a thousand Iranian civilians have killed already

The USA produces lots of fossiel fuel, enough for its own consumption and then some for export.

It’s not obvious, at least to me, that high oil prices would negatively affect (US) oil companies.

OwOarchist Mar 6

Did I make an exception for the US? Obviously, the Trump regime will attack the US as well.

One by one, the naysayers’ objections to EVs melt away. Can’t do cold climates, they said - fixed. Can’t cope with long journeys, they said - fixed.

They also said that if everybody installed a charger in their house the grid would collapse, but suddenly there’s excess capacity for all those data centers

Privately funded capacity. See Microsoft buying a god damned nuclear power plant just to pay for their own data center usage. I hate this timeline

Batteries don’t have ranges?

Fair, but a battery designed for vehicles with a known energy density can be easily described as having a range, because it currently has one primary application.

Not really. The efficiency of vehicles varies significantly. The range of the monstrous EV Hummer is not going to be the same as a more efficient vehicle, even with the same pack.

The title of the article is stupid and journalists should stop being stupid for clicks.

I can agree with all of that, well reasoned.

The title is editorialized, doesn’t reflect the article actual headline.

I’m not saying it’s innacurate. I’m saying it’s better to provide commentary in a comment, rather than altering the title.

heyWhatsay Mar 7

Well, China has always been good at making impressive fireworks.

Do you think LFP batters are particularly fire prone?

Like more so than petrol?

heyWhatsay Mar 7

How prone they are to fire relies on quality control and preventing damage. But EV battery fires are more difficult to control than petroleum fires.

Luckily there is a lot less of them.

Also don’t these meet China’s new super strict battery safety standards?

heyWhatsay Mar 7

I don’t keep up on all the corporate propaganda.

No, it seems you are proud of being ignorant of things.

This takes a real hit out of the new sodium batteries that CATL are bringing online right now.

So cool that we have two batteries that basically fit akk the needed requirements for most applications. Cheap, safe, made from abundant materials, fast charging, long lasting, recyclable, work in the cold.

I get they are not the complete most energy dense batteries you would want to use in your phone or a super high end car where tou can brag about the longest range.

But for renewables and grid storage, for cars for everyday driving or even exceptional once in a year road trips. The problem has been solved with two difference battery techs, it’s amazing

SpaceCowboy Mar 7

For solar and wind you need to store energy when it’s not sunny or windy. You don’t care much about energy density for a stationary battery bank. Solar is already the cheapest way the generate energy even when you include the cost of batteries, sodium batteries just make that even cheaper. That’s huge massive improvement for the energy grid. And that saves lithium for where you need higher energy density.

Solar filling up large sodium batteries, sodium batteries filling up the lithium batteries in you phone and car. That’s the future.
