摘要

The deterioration function calculation device is provided with: a storage unit which stores, for each past use of a secondary battery, the running time of the secondary battery during the use in association with the deterioration rate of the secondary battery during the running time; an equivalent coefficient calculation unit which calculates, for each past use of the secondary battery, an equivalent coefficient for normalizing the running time, on the basis of values related to the use; an equivalent running time calculation unit which calculates, for each running time stored by the storage unit in association with each use and each deterioration rate, an equivalent running time, that is to say, a normalized running time, on the basis of the running time and the equivalent coefficient related to the use related to the running time; and a deterioration function calculation unit which calculates, on the basis of the equivalent running time and the deterioration rate stored by the storage unit in association with the running time used in the calculation of the equivalent running time, a deterioration function representing a relationship between the equivalent running time and the deterioration rate.
