Regarding people questioning durability:

BYD batteries are designed to last for 3000 to 5000 charge cycles
If a car has 400 km range on a charge and can handle 3000 cycles, that’s 1.2 million kilometers.
While we don’t know for sure, there has been nothing to indicate BYD should have compromised on that.
charging 400km or 250 miles in just 5 minutes!
This is crazy fast, 1 MegaWatt charging, 1000 Volt at 1000 ampere!!! This is twice as fast as the best Tesla can do.

BYD stock is soaring on the demonstration of this, while Tesla is dropping like a rock!Edit:
Why the downvotes?I’m not one of the down votes, but safely deploying chargers like these, and keeping cars working with them safe is a huge hurdle.
The temperature control of wires alone will be a big task. As are getting the grid to power these charging stations imagine 1mw demand that suddenly start and stop every 15 minutes. They’re like going to need grid level batteries at these charging stations to smooth out the demand on the grid.
I hope it all happens but in quite skeptical in the near term.
Also not to defend musk in any way, but the Tesla superchargers can do 1000v and as many amps as the connector’s temp sensor allows. Tesla claims sustained 900amp charging, but it’s take that with a lump of salt personally. Not sure if they were using water cooled cabling or not.
The temperature control of wires alone will be a big task.
They use double charging sockets, so with the higher voltage, it’s actually about the same as current fast chargers.
They’re like going to need grid level batteries at these charging stations to smooth out the demand on the grid.
It’s not much different than current charging stations, they can make do with fewer chargers if they are faster. So it probably evens out. BYD has already stated they will put up 400 of these themselves, the rate af fast charging has increased before without issue, why would this be different? Do you think it doesn’t work because it’s from China?
Because if you don’t know already, China is actually ahead on Car batteries now!PS sidenote:
My phone is 1½ years old cheap Xiaomi 13T Pro that charges at 125W, it cost half the Samsung Galaxy S24 Ultra top model at the time, that only had a 65 Watt charger, same size battery but 50% longer to charge! I have not noticed any degradation of the battery. Maybe that’s why I’m less skeptical than most?
And makes your batteries last as long as a set of tires
https://thetechylife.com/how-long-do-byd-batteries-last/
BYD batteries are designed to last for 3000 to 5000 charge cycles
So their normal design practices allow a car to be fully charged every single day 7 days a week for about 10 years!
A car that has 400 km range which is normal today, would than have a battery lifespan of 1.2 - 2.0 million km.And lifespan is normally considered to be until the battery has less than 80% capacity. So you could probably use it for years beyond that.
Based on what?
It’s new technology that allows faster charging, while presumably sustaining similar battery life.
BYD has developed an entirely new battery and charging stack to achieve this.And their stock is soaring on this news.
Do you have a source for the “similar battery life claim”, I didn’t see it in the articles.
That’s the metric BYD has always used for their developments. So it’s a given. Which is why it isn’t mentioned in either of the articles I posted.
Why didn’t you ask HappySkullSplitter if he has any source for his claim?They are being flippant, you are stating it as a fact. If its the standard metric, it should be easy to back that up with a source.
Its actually a given that the faster you charge a given battery, the higher the temp, and therefore the higher the longer term degradation. If BYD has found a way around that, I would actually be interested to know more about that and how they achieved it. Especially as I am in the market for a new car.
Its actually a given that the faster you charge a given battery, the higher the temp, and therefore the higher the longer term degradation.
This would be true if it was the same battery, but have you heard Tesla batteries degrade faster than for other cars sold at the same time with slower charging rates?
These batteries operate at 1000V exactly because it lowers the temperature.
There are industry standards for the durability of car batteries, have you ever heard about car battery durability going down compared to older model cars?BYD and CATL have probably the most durable car batteries in the world, there is absolutely no reason to believe these batteries are less durable than for previous batteries. What happyskullspplitter claiedm is based on ignorance, not on actual knowledge of these batteries.
Just because BYD and CATL have historically been the best, it does not mean they they always will be. So everytime they release a new battery, it is completely reasonable to question if its actually as good as they claim. You seem happy to take it at face value, I am not. If there truely is no degradation to the batteries longevity, why wouldnt BYD actually publish that?

Corrected for degradation 1.08 - 1.80 million km!!!EOL is usually considered to be 75-80% capacity. So you could probably use it for years beyond that.

Not historically, they are currently the best.
it is completely reasonable to question if its actually as good as they claim.
Absolutely, but were the same questions asked when Tesla announced their latest super charger?
Here BYD was ridiculed as being trash, despite they are probably #1 or 2 world leader on car batteries and charging together with CATL.I’ve read 5 articles about it now, and none question the durability of the battery, probably because there is no reason to.
If there truely is no degradation to the batteries longevity, why wouldnt BYD actually publish that?
Of course fast charging degrade relatively more than slower charging, that’s the same for Tesla cars too and all other brands. The point is that these are designed to actually handle the higher charge, so you can actually use it.
But if you use fast charging every day, there will be a noticeable difference for every EV.I never claimed they broke the laws of physics. Just that these will most likely be exactly as durable as what is currently available.
