Electric vehicles capable of traveling nearly 1,000 miles on a single charge could eventually become a reality if Chinese automaker Changan achieves its latest battery ambitions. The company is expanding its partnership with battery giant CATL while continuing development of next-generation solid-state technology.
Changan has outlined plans for batteries capable of delivering over 1,500 kilometers (932 miles) of driving range, which is much farther than the range offered by most electric vehicles currently on sale.
The technology promises improvements in energy density, charging performance, and battery durability. However, the impressive figures are just manufacturer targets, not independently verified results from production vehicles.
The announcement also includes a major expansion of battery manufacturing capacity in China. Together, Changan and CATL are preparing to strengthen their supply chain while developing technologies that could shape future electric vehicles.
Solid-State Batteries Could Deliver 932 Miles Of Range
According to Libattery, Changan is continuing development of its Golden Bell solid-state battery technology, first announced in 2023. The automaker is targeting an energy density of up to 400 Wh/kg, potentially enabling electric vehicles to travel over 1,500 kilometers on a full charge.
Changan also claims its battery technology could deliver improved safety through AI-assisted monitoring. The company has previously suggested a 70 percent safety improvement compared with conventional liquid-electrolyte batteries, although the precise testing conditions are unclear.
Durability is another major focus, with Changan targeting a lifespan exceeding 5,000 charging cycles. Its Golden Bell battery technology also includes a claimed 30-to-80-percent charging time of just nine minutes using 6C fast charging.
Changan And CATL Expand Battery Production
The two companies plan to establish a combined battery production capacity of 75 GWh through their joint venture. Their collaboration also extends to sodium-ion batteries, battery swapping, and solid-state technology.
A new 25 GWh manufacturing facility is planned for the Sichuan-Chongqing region, with production expected to begin during the second half of 2027. The project involves an investment of approximately 5.5 billion yuan ($770 million) and is expected to create around 2,500 jobs.
The facility will supply batteries to Changan’s electric vehicle brands, including Avatr, Deepal, and Nevo. Full production capacity is expected to be reached within three years of operations beginning.
Production Could Begin In 2027
Changan previously outlined plans to begin testing its all-solid-state batteries in vehicles during 2026. The automaker is targeting a gradual transition toward commercial production starting in 2027.
Achieving those goals will depend on overcoming the manufacturing and durability challenges associated with solid-state batteries. For now, the nearly 1,000-mile range represents an ambitious projection rather than a capability available to customers.
If Changan succeeds, the technology could significantly reduce the frequency of charging stops and help make long-distance electric driving far more convenient.
