Abstract: A data processing device that processes measurement data for power storage elements, said device comprising: a storage unit that stores a determination model trained so as to output a score corresponding to whether, upon the input of measurement data measured for each of the power storage elements or for each power storage element group formed by grouping a plurality of the power storage elements, measurement data from a non-conforming power storage element is included in said measurement data; and an identification unit that inputs acquired measurement data into the determination model, and identifies measurement data from a non-conforming power storage element on the basis of the outputted score.

Abstract: This decision method: determines whether measurement data pertaining to a plurality of power storage elements included in a system is periodically stored in a storage device; when the measurement data is determined as stored, determines, on the basis of the acquired measurement data, whether each of the plurality of power storage elements reaches the end of life within a period corresponding to a standard use period at a prescribed temperature; and decides that a power storage element determined as reaching the end of life is required to be replaced.
