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.

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

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!

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.

Not how I read it

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.
