Abstract
According to the present invention, provided is a management device (10) including: a collection unit (11) that collects failure information indicating that a failure has occurred in each of a plurality of power storage systems; a computing unit (12) that computes a failure rate in a group in which the power storage systems each having a predetermined matter in common are collected; and an estimation unit (13) that estimates a characteristic of the failure indicated by the failure information, on the basis of the failure rate and a reference value.
