The Zeekr 7X, with the 800-volt Golden Battery, is capable of adding 1,270 miles of range per hour.

While the U.S. continues to teeter between pro-EV and anti-EV policies with each presidential cycle, electrification isn’t even a debate over in China.

Asia’s second-largest country is moving away from polluting gas cars like few other nations, pushing the boundaries of what EVs can do with each passing day. One of the companies driving this revolution is Geely Group’s Zeekr brand, which makes many high-tech EVs like the 001 crossover, 007 sedan and 009 MPV. Zeekr also happens to be a battery and charging behemoth.

Many of its EVs ride on the Sustainable Experience Architecture (SEA)—also shared by other Geely Group brands like Volvo and Polestar—and it claims to have developed the world’s fastest-charging EV battery. Zeekr claims its Golden battery supports a 5.5 C-rate, meaning it can charge or discharge at 5.5 times its total capacity per hour. At a rate of 1C, for example, a battery would charge in one hour. A rate of 2C would halve that time to 30 minutes. A Tesla Model S briefly charged at a peak of 2.5C in one of our tests, for reference.

The Golden Battery is a big leap. Zeekr says it can charge from 10-80% in just 10.5 minutes.
