To provide a battery management device, a power storage device, a battery management method and a computer program with which it is possible to easily determine the presence of a fault that causes current measurement to become not executable normally.SOLUTION: A battery management device for managing a power storage element and having a shunt resistor connected thereto, comprises: a current measurement unit for measuring current flowing in the shunt resistor using a pair of signal lines connected to both ends of the shunt resistor; a connection line for connecting the signal lines to a reference voltage source via an open-close switch; and a determination unit for determining the presence of a fault that causes connection between the pair of signal lines via the shunt resistor to become faulty, on the basis of a change of the current measured by the current measurement unit when the open-close switch opens or is closed.SELECTED DRAWING: Figure 4

    【課題】電流計測が正常にできなくなる原因となる故障の有無を容易に判定できる電池管理装置、蓄電装置、電池管理方法、及びコンピュータプログラムを提供する。【解決手段】電池管理装置は、シャント抵抗器が接続された蓄電素子を管理する電池管理装置において、前記シャント抵抗器の両端に接続される一対の信号線を用いて、前記シャント抵抗器に流れる電流を計測する電流計測部と、開閉スイッチを介して前記信号線を基準電位源に接続する接続線と、前記開閉スイッチが開閉したときに前記電流計測部が計測する電流の変化に基づいて、前記シャント抵抗器を介した前記一対の信号線の間の接続が不良になる故障の有無を判定する判定部とを備える。【選択図】図4
