Abstract
According to one embodiment, a storage-battery evaluation device includes: a data generator and a deterioration evaluator. The data generator generates a plurality of data items including charge amounts and voltage values of an energy storage device based on current values and the voltage values measured from the energy storage device, the energy storage device being subjected to charge/discharge control in accordance with charge/discharge command values. The deterioration evaluator evaluates a deterioration state of the energy storage device based on a distribution of the voltage values included in the data items the charge amounts of which belong to a first charge-amount range when it is detected that a distribution of first charge/discharge command values satisfies a predetermined condition, the first charge/discharge command values being the charge/discharge command values at which the data items the charge amounts of which belong to the first charge-amount range is obtained.
