The 5-Minute Charge: Is the EV Holy Grail Finally Within Reach?

Chinese battery innovators are pushing EV charging past the 1 MW barrier, threatening to close one of the last gaps between electric and gasoline vehicles

Chinese battery and charging companies have crossed the one-megawatt threshold for passenger vehicle charging at commercial scale, a step that narrows one of the remaining practical differences between electric and petrol-powered cars.

He Xuan, general manager of product lines at Sunwoda, told industry publication 36Kr in March 2026 that 2025 was a turning point, as China's new energy vehicle penetration exceeded 50% and consumer attention moved from range anxiety to charging speed. Sunwoda's current commercial cell charges from 10% to 80% in 15 minutes. A third-generation product under development targets charging in under five minutes, a benchmark that carmakers have long cited but not yet delivered at scale.

Elsewhere in the supply chain, CATL's second-generation Shenxing battery accepts up to 1.3 MW of charging power, adding roughly 2.5 kilometres of range per second. It uses lithium iron phosphate chemistry, a lower-cost alternative to nickel-based cells, at a peak charge rate of 12C, a measure of how fast a battery takes in energy relative to its total capacity. BYD has extended megawatt-level charging, previously confined to heavy trucks, to its mass-market passenger cars through a 1,000-volt electrical architecture.

Sustaining such charge rates without shortening battery life or raising safety risks requires coordinated advances across the supply chain. Sunwoda addresses heat build-up through a combination of two sizes of lithium iron phosphate particles at the nanoscale and microscale, a low-resistance separator, and a full-tab cell design that reduces internal electrical resistance to levels previously seen mainly in laboratory conditions.

As batteries capable of absorbing megawatt-level inputs enter volume production, the constraint is shifting from the vehicle to the charging network. That transition is expected to drive the next major cycle of infrastructure investment across the region.
