Deterioration estimation device, model generation device, deterioration estimation method, model generation method, and program

A deterioration estimation device (20) is provided with a storage processing unit (210) and a calculation unit (240). A storage processing unit (210) acquires a plurality of models from a model generation device (10) and stores the plurality of models in a model storage unit (220). The plurality of models are generated by performing machine learning on training data which uses, as input values, training measurement data indicating the result of measuring the state of the storage battery when the number of charges and discharges is [alpha] i to [alpha] j (where j > = i). The SOH indicating the deterioration state of the storage battery when the number of charges and discharges is [beta] (where [beta] > [alpha] j) is set as a target value. The calculation unit (240) uses the plurality of models stored in the model storage unit (220) to calculate the estimation result of the SOH transition of the battery (30) managed by the deterioration estimation device (20). 劣化推定装置(20)包括存储处理部(210)和计算部(240)。存储处理部(210)从模型生成装置(1
