Abstract: In management device (10) for managing power storage device (20) in which a plurality of power storage blocks (B1 to B3) in which a plurality of series circuits of fuses and power storage cells is connected in parallel is connected in series, equalization controller 15 performs, when a voltage difference among the power storage blocks exceeds a set voltage difference, a control for equalizing power storage blocks (B1 to B3). Fuse blowout determination unit 18 determines, based on a frequency of equalization performed by equalization controller 15, whether one of the fuses is blown.
