Abstract: A management device 21 comprising a main control part 23 that, during charging of a plurality of power storage elements 41 connected in series, outputs a first pull-down signal to a converter 11 so as to lower a charging voltage when the cell voltage of any of the power storage elements 41 is equal to or greater than a first threshold value.
