BYD is testing solid-state EV batteries in its Seal sedan with nearly 1,200 miles of range

It has been over a decade since BYD first began researching and developing the promising new EV battery technology.

Last year, the company reached a milestone by testing its first solid-state battery cells with capacities of 20 Ah and 60 Ah. We knew BYD was planning to launch its first vehicles powered by the new batteries in 2027 after Sun Huajun, the CTO of BYD’s battery business, confirmed the timeline earlier this year.
