- Battery maker CATL has just leaped ahead of BYD and Geely in charge speeds.
- Its latest Shenxing LFP battery can charge from 10-35 % in only one minute.
- A 10-80% charge takes 3 min 44 seconds, cold weather has minimal impact.
Some records stand for decades. Bob Beamon’s 8.9 m 1968 long jump, still unbroken 58 years later, is one. Others, like the 5 minutes it takes BYD’s Blade 2.0 battery to go from 10-70 percent, seem spectacular at the time, but here we are only weeks later and it’s already been smashed not once, but twice.
First it was Geely, whose Golden Brick battery can charge from 10-70 percent in 4 minutes 22 seconds. And now battery giant CATL has made even that look like it was hooked up to a household AC socket.

CATL’s 3rd-gen Shenxing LFP battery stops the clock at 3 minutes 44 seconds. And that’s not even charging to 70 percent, but to 80 percent. Geely’s battery needs almost two minutes longer to reach the same point.
And that’s not the only crushing stat. If you’ve ever charged an EV, you’ll know that charge rates aren’t linear. It takes a while to reach peak charge speed and then the rate falls away again as the battery gets closer to full. But the CATL pack comes out all guns blazing, charging from 10-35 percent in just 1 minute.
And from 10-98 percent takes only 6 minutes and 27 seconds. That compares with 8 minutes 42 seconds for a 10-97 percent fill with Geely’s Golden Brick and 9 minutes for BYD’s Blade 2.0. Or to put it another way, the CATL goes from flat to full 13 seconds faster than it takes a Ford Mustang GTD to lap the Nurburgring.
Cold Weather? No Problem
These numbers are all achieved in optimal temperatures, of course, but CATL threw out another one to show that even in less than ideal condition charging is still really rapid. Drop the temperature to -30˚ C (-22˚F) and the 10-98 percent top-up still only takes 9 minutes.
Unveiling the new battery at its Tech Day Event, CATL claimed the pack’s 0.25 milliohms internal resistance is 50 percent lower than the industry average. It also features multi-point temperature monitoring for each cell and Self-Heating tech that involves using pulses of heat to improve low-temperature charging speeds.
Long Lifespan
Just as importantly, CATL claims that the battery health remains above 90 percent even after 1,000 ultra-fast charge cycles, countering skepticism from BMW engineers about the viability of the new generation of insanely fast-filling Chinese batteries.
BYD has already begun to expand its Flash Charging network to Europe, and CATL also claims it’s looking into bringing its own tech behind China’s borders together with SAIC-GM-Wuling. But don’t bank on it arriving in the US any time soon.
