Abstract:
A deterioration estimation device (1) includes: a discharge control unit (11) configured to discharge a lead-acid battery (3) or a lead-acid battery module (4) that includes a plurality of lead-acid batteries until the lead-acid battery (3) or the lead-acid battery module (4) reaches a predetermined SOC; and a first estimation unit (11) configured to estimate a rate of deterioration of the lead-acid battery (3) or the lead-acid battery module (4) based on internal resistance or conductance derived when the lead-acid battery (3) or the lead-acid battery module (4) is discharged.
