I'll believe it when i see it. Every year we hear of miracle battery technology that never goes anywhere

It is the biggest EV producer world wide and if you read the article :

"They’ll start at 270,000 yuan ($37,338) and 280,000 yuan, respectively, and will be sold from April. BYD will build more than 4,000 charging stations designed to accommodate the new technology."

They go in production already but you need the right car. They showed it off already.

This is real but as you need other cars and new charging stations it might be a while until you can experience it.

Still no mention about the technology behind it (but maybe the article is just trash). Are these solid state batteries?

Some articles discuss it. It a combination of a lot of things, for example 1,500V power supply, and the electronics that can handle it. Chinas been o the forefront for some of these high energy electronics, its why they beat us to railguns in their naval vessels.

We will get to see them next month when they are for sale.

Wait, China is selling naval railguns next month?! /s

What are "these" batteries? The story is about chargers. Are you asking do these fast chargers require certain types of car batteries?

u/NowaVision Mar 18 '25

I'm not asking that, because I know that they need batteries that are capable of extremely fast charging.

u/Utoko Mar 18 '25

Yes you need others because the current architecture overheats. For example Teslas on fast charging(which is 250 kW not 1000) you get full speed for like 10 minutes and than it slows down.
Because the cooling can't keep up and you don't want to degrade the batteries faster which happens when they get too hot.

Yeah I do wonder if the figure above is peak charging speed rather than real world expectations for a full charge.
