BYD’s Second-Generation Blade Battery Makes Western EV Tech Look Ancient (insideevs.com)

The second-generation Blade battery can charge from 10-70% in just about five minutes and from 10-97% in under 10 minutes. More impressively, the company showcased the battery charging flawlessly from 20-97% at -22°F (-30°C) in just about 12 minutes, only around three minutes slower than it charges in normal temperatures.

...

The EV was plugged in at 9% state of charge with 93 kilometers of range (57 miles). In 9 minutes and 51 seconds, it charged up to 97% with the range prediction in their gauge cluster displaying 1,008 kilometers (626 miles). This is likely calibrated for the China Light-Duty Test Cycle (CLTC), which tends to be more optimistic than the Environmental Protection Agency (EPA) test cycle in the U.S.

Still, these charging speeds are way faster than the 20-40 minute charging stops on the latest EVs in the U.S. The new BYD EVs can basically recharge in nearly the same time it takes to refill a gas car. Even the new 1,500 kilowatt (1.5 megawatt) Flash charging stations are arranged like a traditional gas station for cars to quickly drive in and drive out.

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.)
