To diagnose whether a battery module is a genuine product even when the weight of a genuine product and a non-genuine product are the same.SOLUTION: A battery pack 40 includes a displacement measuring device 43 that detects the displacement of a cell 81 when an assembled battery 41 is charged, and a battery ECU 44 that diagnoses whether the assembled battery 41 is genuine, and the battery ECU 44 diagnoses that the assembled battery 41 is a genuine product when the displacement amount δ of the cell 81 detected by the displacement measuring device 43 is within a set range including the displacement amount of the genuine product during charging.SELECTED DRAWING: Figure 1

    【課題】正規品と非正規品とで重量が同等な場合であっても、電池モジュールについて、正規品であるか否かを診断する。【解決手段】電池パック40は、組電池41の充電時にセル81の変位を検出する変位測定装置43と、組電池41が正規品かどうかを診断する電池ECU44とを備える。電池ECU44は、変位測定装置43で検出したセル81の変位量δが、充電時における正規品の変位量を含む設定範囲の範囲内にある場合、組電池41が正規品であると診断する。【選択図】図1
