Quick Takeaways
- Dongfeng solid-state EV battery testing confirms 1,000 km range in winter trials.
- China’s Dongfeng Motor is validating next-generation EV battery technology under extreme cold for commercial deployment.
On January 15, 2026, Dongfeng Motor, one of China’s leading automakers, announced that its solid-state EV battery testing program had entered real-world vehicle trials, targeting more than 1,000 km of driving range. The trials are being carried out by its electric mobility subsidiary Yipai Technology under harsh winter conditions.
The prototype vehicle is equipped with Dongfeng’s 350 Wh/kg solid-state EV battery, a configuration designed to push energy density beyond conventional lithium-ion packs. According to the company, this battery architecture can support over 620 miles of range based on China’s CLTC test cycle.
Dongfeng solid-state EV battery engineered for extreme temperatures
The ongoing winter trials are being conducted in Mohe, China’s northernmost city and a well-known proving ground for cold-weather vehicle validation. Dongfeng is evaluating how the solid-state EV battery performs in three critical areas under sub-zero conditions:
The company has already completed more than 70 separate tests at temperatures ranging between −40°C and −30°C, ensuring that performance remains stable even in environments that severely impact conventional batteries.
Safety and energy density benchmarks exceed national standards
Dongfeng previously disclosed that its solid-state EV battery successfully passed a 170°C thermal chamber test without ignition or rupture. This result exceeds China’s regulatory requirement of 130°C, highlighting the safety advantages of solid-state chemistry.
At extremely low temperatures, the battery retained up to 72 percent of its original capacity at −30°C, a key milestone for electric vehicles expected to operate reliably in cold regions.
Key technical advantages highlighted by Dongfeng
The automaker says the new solid-state EV battery platform delivers:
These attributes are essential for enabling electric vehicles that can match or exceed the usability of combustion-engine models.
Pilot production already underway
Dongfeng has also confirmed that it has completed a 0.2 GWh pilot production line for solid-state EV batteries, with initial units already coming off the line. This early manufacturing capacity allows the company to validate quality, consistency, and scalability before large-scale rollout.
Last August, Dongfeng stated that the technology would be ready for vehicle integration in 2026, with mass production targeted to begin by September of that year. If these timelines are met, the automaker could be among the first global manufacturers to commercialize solid-state EV batteries at scale.
With winter testing now underway and pilot production active, Dongfeng is positioning its solid-state EV battery program as a major step toward longer-range, safer, and more resilient electric vehicles for the next generation of mobility.
