Abstract
In a management device that manages a power storage module in which a plurality of cell blocks in which a plurality of cells are connected in parallel are connected in series, a voltage detector detects a voltage of each of the plurality of cell blocks connected in series. The controller calculates a change value of a voltage of each of the plurality of cell blocks for a certain period of time, integrates absolute values of calculated voltage change values for each of the cell blocks, and determines presence or absence of a cell block including a separated cell that is electrically separated based on an integration value of voltage changes for each of the plurality of cell blocks.
