Ultra-Fast EV Charging
Chinese automakers race to introduce ultra-fast EV charging to rival traditional gasoline stops.
Anonymous
Chinese automakers including Geely, BYD and Li Auto are competing to make EV charging approach the speed of a gasoline stop, aiming to ease range anxiety and revive demand as growth slows in the world’s largest car market. Geely says its new system can charge from 10% to 70% in 4.5 minutes, while BYD and battery maker Sunwoda cite charging from 10% to 97% in about nine minutes; these claims outpace typical charging times from Western rivals. The megawatt-level power brings risks including overheating, battery wear and strain on electrical grids, prompting manufacturers to develop cooling systems and software safeguards. Scaling the technology will also require substantial infrastructure investment and ways to manage peak electricity demand, such as on-site storage and solar. BYD plans a large network of flash chargers, while NIO’s battery-swapping stations offer a different approach to rapid replenishment.
Key Points
1
Geely said its system can deliver peak output of up to 2.25 megawatts from a single charging gun and charge from 10% to 97% in 8 minutes and 40 seconds at room temperature.
2
Li Auto’s flagship EVs use CATL’s 5C Kirin battery, which the articles say can add up to 500 kilometres of range in 12 minutes.
3
The articles compare the Chinese charging claims with Western benchmarks: a Tesla Supercharger typically takes 15 to 25 minutes for a 10%–80% charge, while Mercedes-Benz says its fastest charging can complete that range in as little as 22 minutes.
