摘要
目前,我国新能源汽车发展进入加速阶段,退役动力电池数量持续攀升,梯次利用已成为实现电池资源高效回收与绿色低碳发展的关键路径。受限于退役电池性能不均、分级标准模糊等因素,梯次利用在安全性、经济性与适配性方面面临诸多挑战。据此,以性能分级为核心,构建覆盖基础电性能与动态运行特性的多维指标体系,进而建立基于加权评分的综合评价模型,实现退役电池的科学分级与场景匹配。研究旨在推动梯次利用的标准化、体系化发展,为行业实践提供理论支撑与方法参考。
Currently,China's new energy vehicle development has entered an accelerated phase,with the number of retired power batteries continuously rising.Cascade utilization has become a key pathway for achieving efficient battery resource recovery and green low-carbon development.Limited by factors such as uneven performance of retired batteries and ambiguous grading standards,cascade utilization faces numerous challenges in safety,economics,and compatibility.Therefore,focusing on performance grading,this paper constructs a multi-dimensional indicator system covering basic electrical performance and dynamic operational characteristics,and subsequently establishes a comprehensive evaluation model based on weighted scoring to achieve scientific grading and scenario matching of retired batteries.The research aims to promote standardized and systematic development of cascade utilization,providing theoretical support and methodological reference for industry practice.
