To provide a capacity estimation system, a capacity estimation method and a program that can improve estimation precision of battery capacity of a secondary battery.SOLUTION: A capacity estimation system (1) comprises: an acquisition part (110) which acquires, for each of a plurality of vehicles (10), transition information representing a transition of the battery capacity of a secondary battery of the vehicle and use history information representing a use history of the secondary battery; a database generation part (120) which generates a database including transition information and use history information of each vehicle; a selection part (140) which selects at least transition information between transition information and use history information similar to transition information and use history information of an object vehicle among the plurality of vehicles; and an estimation part which estimates the battery capacity of the secondary battery of the object vehicle based upon the transition information selected by the selection part.SELECTED DRAWING: Figure 1
