BYD's latest EVs can get close to full charge in just 12 minutes

The Chinese have been producing phones that charge at like for many years as well. Turns out no one else uses them because the batteries are completely worn out after a short time.

Tenuous, unsourced statement alone - that has no bearing on automotive batteries which use different battery chemistry, design choices, and validation processes. Apples to oranges.

phones don’t run at 800V, at higher voltage you need lower amperage to push the same energy

And cars don't charge at 200w. Have you heard of a thing called C-rate?

The total voltage or amperage of the battery pack does not mean anything for the battery cells. You can put more cells in series and get a higher voltage at lower current, or more in parallel and get a higher current at a lower voltage. But all individual cells will run at the same voltage in either configuration (iirc between 3 and 4V), and the current per cell will also be the same for a given load regardless of the situation.

The main thing a higher battery pack voltage accomplishes is that the cables connected to the battery don't need to be as thick, as the required thickness of a cable depends only on current, not voltage.

Fast charging does negligible battery wear on a phone compared to slow charging
