一种退役动力电池诊断的方法和装置
摘要：
本发明提供一种退役动力电池诊断的方法和装置，所述方法包括下述步骤：(1)根据电池模组内电池单体间的一致性确定所述电池模组是否拆解；(2)检测未拆解的所述电池模组和拆解的所述电池模组内的电池单体以确定其梯次利用价值；(3)根据所述梯次利用价值将所述电池模组和所述电池单体分类。该诊断过程简单、条理清晰，诊断效率大大提高，降低了诊断过程的成本，提高了退役动力电池梯次利用的技术经济性，为退役动力电池的梯次利用提供了良好的技术指导。
摘要（英）：

The invention provides a retired power battery diagnosis method and device. The method comprises the following steps: (1) determining whether a battery module group is disassembled or not according tothe consistency of battery cells in the battery module group; (2) detecting an undisassembled battery module group and the battery cells in a disassembled battery module group to determine the echelon utilization value of the battery module group; (3) classifying the battery module group and the battery cells according to the echelon utilization values. The diagnosis process is simple and orderly, the diagnosis efficiency is greatly improved, the cost of the diagnosis process is reduced, the technical economy of echelon utilization of a retired power battery is improved, and good technical guidance is provided for echelon utilization of the retired power battery.
