An apparatus for identifying a position of an abnormality occurred in a secondary battery system includes an information acquisition unit for acquiring information about a module (module information) from among a plurality of modules included in a module series that accommodates a block for which the difference between a block voltage value and a block voltage value after a primary delay has changed so as to exceed a voltage threshold within a preset time before and after the point in time at which the block voltage value and series current value stopped being correlated, a notification reception unit for receiving a notification about the occurrence of an abnormality in a secondary battery, and a module specification unit for specifying at least the module corresponding to the latest module information as the module in which an abnormality occurred when the notification reception unit receives a notification.
