Abstract
This method for ascertaining the state of a fixed storage battery has: (a1) a step for storing operating history data for a storage battery; (a2) a step in which the storage battery is completely discharged and the charging energy required to fully charge the storage battery is measured by a charge amount measurement device, thereby updating, at regular intervals, data on the charging energy required for the storage battery to be fully charged; and (a3) a step for estimating the electric storage capacity of the storage battery from the operating history data and the updated data on the charging energy required for the storage battery to be fully charged.
