Because discharging 100kw of energy quickly would be dangerous.
Comment on BYD’s Second-Generation Blade Battery Makes Western EV Tech Look Ancient

can charge from 10-70% in just about five minutes
Why is that always a metric? Yeah, with a tiny battery or a kilowatt line maybe.

Makes sense.

and an external cooling system because moving that much energy makes heat.

Cycle count is important for the lifetime estimate on the battery, how long before you have to spend a large portion of the cost of the car on replacing / refurbishing a key component.
“Fill up” time is the most obvious and common ‘maintenance’ anyone will ever do on their vehicle. One of the biggest objections large swaths of the population have about EVs is/was that could take an hour or more for each stop on a long road trip or if you can’t charge at home. (apartment / street parking / etc.) They usually do 10-70%r 80 or whatever because the speed trails off exponentially closer to 100%. (logarithmically? whichever.)

Because the power charging curve is non linear. You have to charge the battery slowly when it’s almost depleted or full. So they only post the numbers that make them sound best.

Got it. Thanks!
