CATL says its third-generation Shenxing battery can push an EV from 10% to 98% in 6 minutes and 27 seconds, a claim that sounds less like incremental progress and more like a direct challenge to the idea that EV fast charging has to be slow, hot, or annoying. The company unveiled the pack at Super Technology Day 2026 and paired the headline figure with colder-weather numbers that are just as aggressive.
Shenxing EV fast charging claims
According to CATL, the battery can reach 10-35% in 1 minute, 10-80% in 3 minutes 44 seconds, and 20-98% in just over 9 minutes at -30°C. That last detail matters more than the marketing gloss: plenty of batteries look speedy in ideal conditions, but cold-weather charging is where many EVs start acting like they need a cup of tea first.
CATL says the trick is not just higher power, but controlling heat. The company claims it reduced internal resistance to an average of 0.25 mΩ, about 50% lower than other batteries designed for very fast charging. If that figure holds up outside a product stage, it would point to a more practical race in EV batteries: not just who can dump in electrons fastest, but who can do it without cooking the pack.
The pack is also said to tolerate 1,000 cycles of ultra-fast charging while keeping more than 90% of its capacity. That is the kind of number automakers love to repeat, because the real pain point for buyers is not one dramatic charge session but whether the battery still feels healthy after years of abuse.
What CATL is trying to solve
Beyond speed, CATL says the battery includes self-heating technology and a system aimed at reducing rapid discharge in low temperatures. That is a sensible response to a familiar EV problem: fast charging is impressive in a demo, but range anxiety gets nastier when the thermometer drops and the battery starts sulking.
The broader arms race here is obvious. Tesla, BYD, and several Chinese battery makers have all spent the last few years pushing charging speeds higher, but the next leap is clearly about usable speed across seasons, not just lab-friendly peak performance. If CATL can translate Shenxing’s claims into mass production, competitors will have to answer with something more meaningful than another shiny charging slide.
The EV battery race beyond peak charging speed
The big unknown is how widely automakers will actually deploy it, and whether charging infrastructure can keep up with batteries that want to refill almost as quickly as you can buy coffee. For now, CATL has set a new benchmark in battery marketing and, potentially, in real-world EV convenience too.
