Game-changing new battery tech promises near-instant charging—but the leap forward may come with big hurdles.

Eunice Lee, the Asian autos analyst at Bernstein, an investment research company, cited Chinese rivals XPeng and Zeekr, whose respective 5C and 5.5C charging systems can add about 280 miles and 342 miles of range in 10 minutes. She was “generally impressed” by BYD’s claims, after it had lagged behind rivals.

Chinese automaker BYD continues to leave Tesla in the dust. The company introduced a new battery system on Monday that it claims can charge an electric vehicle in just five minutes, about the same time it takes to refuel a traditional car.
