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.

No. The cold tests starts at 20% and the normal test at 10%. My guess is that charging from 10-20% at -30 C takes a lot longer. Still a good battery, but they're fudging the numbers here.

True, but I don't need to charge at -30C, and this thing charges FAST.

I do need to charge at those temps. Not all of us live in warm climates.

Considering the speed of 20%+ charging, what would you predict 10-20% to be?

Even if you add another 10 minutes making the total 22 minutes, at that temperature I'd be impressed

Wow. I think if I lived in that sort of climate I might not be driving an electric car. But I also think the likelihood of me moving to a climate that hostile is low. Keep safe out there!

People living in -30°C don't necessarily do so all year round. The temperature varies between -30 and +30 during the full year where I live. Our EVs handle it just fine, even for long trips. 👍👍

A fossil fuel car also consumes more gas in cold temperatures, as far as I've understood. Doesn't stop anyone in colder climate from using a car at all.
