<p>A battery module composition determining system comprises a manufacturing line that manufactures a module battery composed of a plurality of cells, a charging apparatus for charging the module battery, and an exchange instructing unit for determining the composition of the module battery. The battery module composition determining system is provided with: a manufacturing information collecting unit that collects, from the manufacturing line, manufacturing inspection data that has, associated with each other, a plurality of manufacturing conditions that were set for the cells, and performance deterioration information indicating the deterioration states of the cells manufactured according to each of the manufacturing conditions; an operating information collecting unit that collects, from the charging apparatus, operating data including operating track-record information that indicates charging track records of the cells upon charging the module battery; and a performance evaluating unit that selects, from the manufacturing inspection data, and on the basis of the performance deterioration information and the operating track-record information of the cells, performance deterioration information that indicates a deteriorated state nearest to the operating track-record information, and that specifies, when the amount of deteriorated state that indicates the degree of the deteriorated state of a cell manufactured according to manufacturing conditions corresponding to the selected performance deterioration information is outside a prescribed threshold value, the cell having the operating track-record information as the cell to be exchanged.</p> |
