Beschreibung
Zusammenfassung:	A battery management system according to one aspect includes: an acquisition unit configured to acquire reference data indicating a state of a rechargeable battery in a reference period and target data indicating a state of the rechargeable battery in a target period that is after the reference period; a characteristic calculation unit configured to calculate a characteristic value corresponding to a state of charge of the rechargeable battery in the reference period as a reference characteristic value based on the reference data, and calculate a characteristic value corresponding to a state of charge of the rechargeable battery in the target period as a target characteristic value based on the target data; and a ratio calculation unit configured to calculate a ratio indicating a relationship between the reference characteristic value and the target characteristic value, as a reference value for predicting a lifespan of the rechargeable battery.
