<P>PROBLEM TO BE SOLVED: To provide a cell combined system of a battery pack capable of effectively utilizing grading results of battery cells and securing the performance of the battery pack at a maximum. <P>SOLUTION: Aging boxes (loads M) stored in storage shelves 3 of an automatic warehouse automatically perform aging processing of battery cells therein. A host controller 9 records battery characteristic data obtained by the aging processing, performs grading of the battery cells based on the battery characteristic data, and stores where the battery cells of the same grade are stored to generate a database. A battery assembling device 21 extracts a plurality of battery cells of the same grade from one or more aging boxes transported from the automatic warehouse, and assembles battery packs 22a-22d of a predetermined grade using these respective battery cells. <P>COPYRIGHT: (C)2013,JPO&INPIT |
