Claim 12:
13. An information processing method, comprising:
selecting a pair of charge curve data and discharge curve data from a set of one or more first reference data and a set of one or more second reference data, based on a distribution between charge amounts and voltage values in a plurality of operation data each including a charge amount and a voltage value acquired from a target rechargeable battery that is being recharged and discharged,
the one or more first reference data each including charge curve data of a rechargeable battery and including information on a state of the rechargeable battery, the charge curve data representing relationship between a charge amount and a voltage value of the rechargeable battery,
the one or more second reference data each including discharge curve data of a rechargeable battery and including information on a state of the rechargeable battery, the discharge curve data representing a relationship between a charge amount and a voltage value of the rechargeable battery;

acquiring information on states of rechargeable batteries corresponding to the charge curve data and the discharge curve data in the selected pair from the first reference data and the second reference data including the charge curve data and the discharge curve data in the selected pair; and
estimating a state of the target rechargeable battery based on the acquired information.
