Changan Automobile is progressing steadily with its Jinzhongzhao all-solid-state battery project, targeting on-robot and on-vehicle validation by the third quarter of this year. The automaker outlined these plans in response to investor inquiries, noting that prototype installations in industrial robots and production vehicles will commence ahead of Q3.
In March 2025, Changan announced it would begin fitting all-solid-state cells into prototype vehicles by the end of that year, with on-vehicle validation scheduled for 2026 and gradual mass production planned by 2027. The Jinzhongzhao solid-state battery features an energy density of approximately 400 watt-hours per kilogram and is projected to deliver more than 1,500 kilometers of driving range on a single charge, addressing a key barrier to broader electric vehicle adoption.
Changan has also integrated AI-powered remote diagnostics into its battery management system, improving the safety performance of its solid-state cells by around 70 percent compared to conventional liquid-electrolyte designs. The project’s roadmap includes launching eight cell variants—including liquid, semi-solid and solid-state chemistries—by 2030, supported by a combined production capacity target of at least 150 gigawatt-hours.
At the Guangzhou Auto Show in November 2023, Changan introduced the Jinzhongzhao brand and outlined its strategy for these eight distinct cell types. Several other domestic automakers and cell manufacturers are pursuing similar timelines. One major automaker recently completed its first in-house solid-state battery pack and is preparing vehicle integration trials, while leading suppliers anticipate small-scale solid-state production by 2027 and are already testing semi-solid solutions in prototype cars.
Changan’s effort to validate solid-state technology in both robots and vehicles underscores the industry’s broader shift toward advanced battery systems promising higher energy density, enhanced safety and extended driving ranges.
