退役电池梯次利用安全性分析
摘要:为解决环境污染和资源紧缺问题，国家大力支持发展新能源汽车产业，随着电动汽车数量的增加，车用退役电池如何回收利用成为产业发展的关键问题。从国内外政策分析、梯次利用环节的安全问题剖析等方面考虑退役电池梯次利用的安全性。梯次利用环节包括退役电池收集拆解、筛选、重组、应用等，着重从筛选重组环节入手，结合退役电池健康状态和剩余容量的状态评估，进行一致性分选的安全分析；同时根据现有的重组技术改善电池一致性差的问题，并对重组系统的安全性进行评估。依据上述分析，给出退役电池进行梯次利用各环节所存在的安全隐患，提出相应的管理政策，保障电池梯次利用的安全，为未来发展退役电池的梯次利用系统提供了参考。
Abstract：In order to solve the problems of environmental pollution and resource shortage, our government strongly supports the development of the new energy vehicle industry. With the increase of the number of electric vehicles, how to recycle the retired batteries for automobile has become a key issue for the development of the industry. The safety of cascaded utilization of retired batteries was considered from the aspects of domestic and foreign policy analysis and safety analysis of the cascaded utilization process. Cascaded utilization includes decommissioned batteries collection and disassembly, screening, recombination, application, etc., focusing on screening and recombination, combined with the health status of decommissioned batteries and the state evaluation of the remaining capacity, consistency sorting safety analysis. At the same time, the problem of poor battery consistency was improved according to the existing recombination technology, and the safety of the recombination system was evaluated. On the basis of the above analysis, the hidden safety risks in each link of the phased utilization of retired batteries are presented, and the corresponding management policies are proposed to guarantee the safety of the cascaded utilization of batteries, which provides a reference for the future development of the cascaded utilization system of retired batteries.
