A battery managing device includes a first calculator, a second calculator, a determiner, and a controller. The first calculator calculates a provisional value indicating a charge state of a battery provided in a vehicle including an electric motor as a drive source. The second calculator calculates the charge state of the battery based on a condition obtained by comparing the provisional value and a boundary point which is on a boundary between a plurality of regions divided in accordance with an available charged amount of the battery. The boundary point is determined based on the available charged amount of the battery in a predetermined degradation state. The determiner determines in which region among the regions the charge state of the battery locates. The controller controls to charge and discharge the battery in accordance with the region determined by the determiner.
