Chinese EV Makers Race Ahead With Ultra-Fast Charging Technology

Chinese electric vehicle makers are rapidly advancing EV charging technology, with Geely Auto unveiling a system that can recharge a battery from 10% to 70% in just 4.5 minutes. This development places Chinese automakers, including BYD and CATL, significantly ahead of many competitors globally in achieving charging speeds comparable to refueling gasoline vehicles.

Geely's new technology, announced Wednesday, can also charge an EV from 10% to 97% in 8 minutes and 40 seconds. This leap follows similar announcements from BYD in March, which launched a new generation of its "blade" EV battery capable of charging from 10% to 70% in five minutes, and CATL in April, which rolled out technology that can charge an EV from 10% to 80% in under four minutes.

Analysts note that this intense competition in charging technology is driven by fierce domestic market competition and the desire to eliminate range anxiety, a major barrier to EV adoption. China currently boasts over 100 domestic passenger car brands, intensifying the race for technological innovation.

However, experts caution that widespread adoption of these ultrafast charging technologies faces hurdles. Chris Liu, a senior analyst at Omdia, points out that the battery itself must be able to accept high charging currents repeatedly without overheating or degrading significantly. Furthermore, the charging infrastructure must be able to support these high power levels.

While Geely, BYD, and CATL's technologies rely on charging power exceeding 1 megawatt, the majority of China's public charging stations currently operate below this threshold. Stephen Chan, an analyst at S&P Global Ratings, highlighted that network expansions and grid updates are necessary for large-scale implementation. BYD is aiming to deploy 90,000 superfast charging stations by 2028, indicating significant investment in infrastructure.

In contrast, the United States lags behind China in ultrafast EV charging. Typical fast-charging sessions in the U.S. range from 20 to 40 minutes for a 10% to 80% charge, although some newer models can achieve charging times closer to 18 to 20 minutes under ideal conditions. Neal Ganguli, a partner at AlixPartners, suggests that the U.S. may be pursuing a more moderate approach to EV charging upgrades rather than matching China's rapid pace in "megawatt race" technology.
