The invention discloses a method for deciding an active remanufacturing time domain based on cyclic aging degradation of a power battery. The method comprises the following steps of: quantitatively representing a performance degradation state of the power battery based on monomer inconsistency; decision-making of an active remanufacturing time domain of the power battery based on fusion of the analytical model and twin data; by analyzing influence factors related to active remanufacturing time domain decision making of the power battery, an influence rule of monomer inconsistency of the power battery under a multi-scale structure on the overall performance degradation state of the power battery is disclosed; on the basis of extracting performance parameter data of a single power battery, the overall performance degradation state of the power battery is mapped by applying the Sklar theory, and the upper limit and the lower limit of an active remanufacturing time domain of the power battery are further decided
