東風將於2026年推出620英里固態電動車

东风汽车准备在今年9月推出一款采用固态电池技术的新能源汽车。这款车型在CLTC工况下续航里程有望突破1000公里(约合621英里),即便按照更为严格的EPA标准测算,续航能力也能保持在400英里以上。

该车型搭载了能量密度高达350Wh/kg的复合固态电池,具有惊人的环境适应性:在-30℃至130℃(-22°F至266°F)极端温度范围内仍能保持稳定性能,且在低温环境下容量保持率超过72%。电池采用创新的三元正极+硅碳负极结构,并配备自主研发的氧化物-聚合物复合固态电解质。

充电技术方面,东风”马赫E”电动平台搭载1700V碳化硅功率模块,支持高达2MW的超级快充。据称可实现”充电5分钟续航450公里”(约280英里/5分钟),相当于每秒充入约2.4公里续航能力。

目前全球多家车企都在固态电池领域取得进展:
1. Stellantis集团计划明年推出搭载固态电池的Dodge Charger Daytona电动车型测试车队
2. 美国Factorial Energy正在开发400Wh/kg固态电池
3. 丰田、宝马等传统巨头也在加快固态电池研发

行业专家指出,虽然实验室数据亮眼,但固态电池量产仍需克服成本、良品率等现实挑战。中国企业在动力电池领域已形成完整产业链优势,这种技术创新或将重塑全球电动车产业格局。

值得注意的是,由于中美技术标准差异和贸易壁垒,这类先进技术车型短期内可能主要在亚洲和欧洲市场投放。但随着技术迭代加速,固态电池有望在未来3-5年内带来电动车性能的颠覆性突破。
