The present invention provides a battery management device, a power storage device, a battery management method, and a computer program. The battery management device manages a power storage element that has a shunt resistor connected thereto, and comprises a current measurement unit that uses a pair of signal lines that are connected to either end of the shunt resistor to measure the current flowing in the shunt resistor; a connection line that connects the signal lines to a reference potential source via an opening/closing switch; and a determination unit that, on the basis of the change in the current measured by the current measurement unit when the opening/closing switch has opened/closed, determines whether there is trouble that could lead to failure of the connection between the pair of signal lines as mediated by the shunt resistor.

    本发明提供一种电池管理装置、蓄电装置、电池管理方法以及计算机程序。电池管理装置对连接有分流电阻器的蓄电元件进行管理。电池管理装置具备:电流测量部,使用与所述分流电阻器的两端连接的一对信号线,测量流过所述分流电阻器的电流;连接线,经由开闭开关而将所述信号线与基准电位源连接;和判定部,基于在所述开闭开关开闭时所述电流测量部测量的电流的变化,判定有无经由所述分流电阻器的所述一对信号线之间的连接成为不良的故障。
