Changan Advances Solid-State Battery Testing in Robots and Vehicles by Third Quarter

Changan Automobile is steadily advancing its Jinzhongzhao solid-state battery project, planning to integrate and test the technology in robots and vehicles before the third quarter of this year. The Chinese automaker shared this update in response to investor inquiries on a communication platform, though it provided no additional specifics. Earlier, in March 2025, Changan outlined its roadmap: starting prototype vehicle installations by the end of 2025, conducting on-vehicle validation in 2026, and moving toward mass production of all-solid-state batteries by 2027. The technology offers an energy density of 400 Wh/kg, enabling more than 1,500 kilometers of driving range per charge and addressing common concerns about electric vehicle endurance. Through AI-driven remote diagnostics, Changan has improved the battery's safety by 70%, aiming to resolve issues associated with traditional liquid electrolytes. The Jinzhongzhao brand was introduced at the November 2023 Guangzhou auto show, where Changan announced plans to develop eight types of battery cells—including liquid, semi-solid, and full-solid variants—by 2030, backed by at least 150 GWh of production capacity. Similar initiatives are progressing elsewhere: Geely Auto aims to complete its first in-house all-solid-state battery pack this year and begin vehicle testing. In contrast, battery giants like CATL and BYD are taking a more cautious approach, targeting small-scale production of all-solid-state batteries around 2027.
