Recently, Dongfeng Motor announced that its prototype vehicle equipped with an all-solid-state battery has officially commenced extreme cold-weather winter testing. The test is being conducted in northeastern China, where temperatures drop as low as minus 30 degrees Celsius, aiming to comprehensively evaluate the battery’s performance under extreme cold conditions—including charge/discharge efficiency, range stability, and safety. As a promising next-generation battery technology, solid-state batteries are widely regarded as a key solution to overcoming the limitations of current lithium-ion batteries, thanks to their higher energy density, enhanced safety, and broader operational temperature range. By being among the first automakers to install solid-state batteries in a test vehicle and conduct real-world validation, Dongfeng has made tangible progress in its strategic push for core new energy technologies. If the test results meet expectations, Dongfeng could become one of the world’s first automakers to mass-produce vehicles with solid-state batteries, further strengthening its competitiveness in both the Chinese and global new energy vehicle markets.Notably, this winter test also evaluates multiple aspects beyond battery performance, such as the vehicle’s thermal management system, regenerative braking efficiency, and overall driving experience in sub-zero conditions, providing critical data for future engineering refinement and mass production.
近日，东风汽车宣布其搭载全固态电池的样车已正式开启极寒环境下的冬季测试。此次冬测地点选在中国东北地区，气温低至零下30摄氏度，旨在全面验证固态电池在极端低温条件下的性能表现，包括充放电效率、续航稳定性及安全性等关键指标。作为下一代动力电池技术的重要方向，固态电池因具备高能量密度、高安全性和更宽的工作温度范围，被业界视为突破当前锂离子电池瓶颈的关键路径。东风此次率先将固态电池装车并投入实地测试，标志着其在新能源核心技术领域的战略布局取得实质性进展。若测试结果符合预期，东风有望成为全球首批实现固态电池量产上车的车企之一，进一步巩固其在中国乃至全球新能源汽车市场的竞争力。值得注意的是，本次冬测不仅关注电池本身的性能，还将评估整车在低温环境下的热管理系统、能量回收效率以及驾驶体验等多个维度，为后续工程优化和量产落地提供数据支撑。
