The present disclosure provides an estimation method including: performing a regression analysis between a value of a feature point appearing on a differential curve indicating a charge/discharge curve of a reference battery with respect to a voltage value of an integrated current amount, and at least one of a capacity value or an internal resistance value of the reference battery, for each different degree of degradation; and estimating at least one of a capacity value or an internal resistance value of the target battery to be estimated based on a result of the regression analysis and based on a value related to a feature point appearing on a differential curve of the target battery to be estimated. 本公开提供了一种估计方法，该估计方法包括：针对每个不同的劣化程度，在指示参照蓄电池相对于积分电流量的电压值的充放电曲线的微分曲线上出现的特征点的值与该参照蓄电池的容量值或内阻值中的至少一个之间执行回归分析；并且基于回归分析的结果，并且基于与在待估计的目标蓄电池的微分曲线上出现的特征点相关的值，估计待估计的目标蓄电池的容量值或内阻值中的至少一个。
