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.

Charge time sounds great, but what about the number of charge cycles (I.e. longevity), the article did not mention that.

They don't mention it, but I highly suspect its actually not significant.

I used to think fast charging did the same thing, but it turns out that even the heaviest wattage implementations have negligible effects on cycles and health.

As long as your driver is smart enough to control or manipulate the voltage at certain capacities (<15% and >85%), the higher power won't affect the cell quality.

You are correct. This is for phones, where it is worse than for EVs, but:
