To provide a battery diagnosis system capable of accurately diagnosing whether a secondary battery is a genuine product.SOLUTION: The battery diagnosis system includes: a voltage sensor 421 that measures the voltage of a battery 41; and processors 431 and 701. The processors 431 and 701 diagnose whether the battery 41 is a genuine product based on a voltage curve showing the time change of the voltage measured by the voltage sensor 421 during the diagnostic period that includes both charging and discharging periods and rest periods.SELECTED DRAWING: Figure 9

    【課題】二次電池が正規品であるかどうかを高精度に診断する。【解決手段】電池診断システムは、バッテリ41の電圧を測定する電圧センサ421と、プロセッサ431,701とを備える。プロセッサ431,701は、充放電期間と休止期間との両方を含む診断対象期間中に電圧センサ421により測定された電圧の時間変化を示す電圧カーブに基づいて、バッテリ41が正規品であるかどうかを診断する。【選択図】図9
