退役动力电池梯次利用关键技术概述
摘要：摘要退役动力电池的后续处理对新能源汽车产业和环境的可持续发展提出严峻挑战。动力电池梯次利用是有效发挥动力电池剩余价值、实现新能源汽车行业绿色发展的有效途径。退役电池的健康状态直接决定了电池能否被再次利用,研究退役动力电池健康状态检测技术具有重大现实意义。除此之外,由于退役电池是已经老化的电池,电池的循环性能、倍率性能及安全性能等相比新电池会有所下降,开展退役电池梯次利用中的性能评估,可以更好地对其后续的使用进行管控。本文梳理了退役动力电池在一致性筛选、性能测试、重组、梯次场景选择及后续使用时的一致性及安全管理中的关键技术,重点分析了不同测试方法的原理及优缺点。清晰论述了梯次利用关键技术发展现状及不足,有助于完善退役电池梯次利用体系。
Abstract:：The follow-up treatment of decommissioned power batteries is posing serious challenge to the sustainable development of electric vehicle industry and the environment. Echelon utilization of power batteries is an effective way to play the remaining value of power batteries and realize the green development of the new energy vehicle industry. The state of health of decommissioned batteries directly determines whether the batteries can be reused, and it is of great practical significance to study the state of health detection technology of decommissioned power batteries. In addition, since decommissioned batteries have undergone aging, their cycling performance, rate performance and safety performance will be lower than that of new. The characteristics evaluation in the echelon utilization of decommissioned batteries is beneficial for the subsequent use management. In this paper, the key technologies of battery screening, characteristics testing, reorganization, selection of echelon scenes and consistency and safety management during the echelon utilization were sorted out, and the principles, advantages and disadvantages of different test methods were mainly analyzed. The development status and deficiencies of key technologies for echelon utilization were clearly discussed, which may help consummate the echelon utilization system of retired batteries.
