摘要

PROBLEM TO BE SOLVED: To estimate future SOH of a storage battery with high accuracy. A deterioration estimation device 20 includes a storage processing unit 210 and a calculation unit 240. The storage processing unit 210 acquires a plurality of models from the model generation device 10 and stores them in the model storage unit 220. In these plurality of models, the number of charge / discharge is β (where β> αj) with the training measurement data showing the result of measuring the state of the storage battery when the number of charge / discharge is from αi to αj (where j ≧ i) as an input value. ), It is generated by machine learning the training data with SOH as the target value indicating the deterioration state of the storage battery. The calculation unit 240 calculates the estimation result of the transition of the SOH of the storage battery 30 managed by the deterioration estimation device 20 by using a plurality of models in which the model storage unit 220 is stored.
