To solve a problem in which it is difficult for a conventional abnormality detection device for a power storage device to adapt to a current increase in the capacity of an in-vehicle battery.SOLUTION: An abnormality detection device 10 according to the present invention includes an electronic control unit 21, current measurement means 22, voltage measurement means 23, storage means 24, bus bar resistance calculation means 25, abnormality determination means 26, input/output limiting means 27, vehicle state determination means 28, and notification means 29. The abnormality detection device 10 safely controls an in-vehicle battery 12, and promptly notifies an occupant of a vehicle 11 of abnormality in the in-vehicle battery 12 when the abnormality is detected. The occupant therefore can early perform repair or the like on the in-vehicle battery 12, and the vehicle 11 can be safely driven.SELECTED DRAWING: Figure 2

    【課題】従来の蓄電装置の異常検出装置では、近年の車載用バッテリの大容量化に対応し難いという課題があった。【解決手段】本発明の異常検出装置10は、電子制御ユニット21と、電流測定手段22と、電圧測定手段23と、記憶手段24と、バスバー抵抗算出手段25と、異常判定手段26と、入出力制限手段27と、車両状態判定手段28と、報知手段29と、を有している。そして、異常検出装置10は、車載用バッテリ12を安全に制御すると共に、車載用バッテリ12の異常を検出した際には、車両11の乗員にその異常を速やかに報知することで、乗員は、早期に車載用バッテリ12の修理対応等を行うことができ、車両11の安全走行が実現される。【選択図】図2
