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.
Claims6
A management device for managing a power storage device, in which a plurality of power storage blocks, where a plurality of series circuits each configured of a fuse and a power storage cell are connected in parallel, are connected in series, the management device comprising:
- an equalization controller for performing, when at least one voltage difference among the power storage blocks exceeds a set voltage difference, a control for equalizing the power storage blocks;
- and
- a blowout determination unit for determining, based on a frequency of equalization performed by the equalization controller, whether at least one of the fuses is blown.
