All EV batteries aren’t “a battery that size”. They’re a bunch of small batteries all strung together. The “battery that size” statement you made is pretty much meaningless.
It’s very much physically possible to charge a battery pack at mostly empty to mostly full in 5 minutes. The tech and chemical side of actually getting it done hasn’t quite officially happened yet. Battery charge\discharge rates are measured in “C”. One C is an hour for a 0 to 100% charge. So six C would be 0 to 100 in 10 minutes. That’s doable right now. You’d need 12 C for a 0 to 100% charge in 5 minutes. That hasn’t happened yet, but it’s getting pretty close. 11 C can be done to go from 0 to 80%.
Likely, BYD’s charging statement is based for the regular layman such as yourself and refers to something along the lines of a charge from 10% up to 80%.
As a side note, it’s also annoying having these “new EV battery has x amount of range” is dumb. You could get that range 20 years ago if you made the battery pack a lot bigger. What you need to know is the energy density and the size. Like 400 WH per kilogram is currently a really good capacity. Double what you could get from like five years ago.
If your dumb fucking ass let an ai near your work AND you didn’t have any recent backups that it couldnt have access to; you’re really extra fucking stupid.
