Abstract

A cell degradation level calculation device for electrochemical cell stack according to an embodiment includes: a first calculation unit that calculates a first target voltage value based on first characteristics data; a second calculation unit that calculates a second target voltage value based on second characteristics data; and a third calculation unit that calculates a cell degradation level showing a degradation level of a cell based on the first target voltage value and the second target voltage value. The first target voltage value is the voltage value at which a voltage-value decrease rate reaches a first threshold value in a second time slot of the first characteristics data. The second target voltage value is the voltage value at which the voltage-value decrease rate reaches a second threshold value in a fourth time slot of the second characteristics data.
