Chinese EV battery makers race to cut charging times under 10 minutes

other · 2026-04-28

At the Beijing Auto Show, fast-charging technology has taken center stage as Chinese battery suppliers compete to reduce charging times. Second-tier suppliers including CALB Group, EVE Energy, and Sunwoda unveiled batteries that can charge from 10% to 70% in under 10 minutes. Sunwoda also introduced a fast-charging battery for electric bicycles, reaching 80% from 10% in 20 minutes with a lifespan of at least 2,000 cycles. EV start-up Nio demonstrated a full battery swap in three minutes. The race follows launches by BYD and CATL of batteries that can charge from 10% to 97% in less than 10 minutes. Li Xianyang, a battery specialist at Sunwoda, noted that replenishing energy is the final frontier where EVs have yet to fully surpass petrol cars in China, driving competition on time.
