Abstract:
A charging/discharging control device, comprising:a secondary battery formed of a battery assembly with a plurality of cells combined with one another; a memory effect determinator for determining whether a discharging memory effect has occurred, based on at least one of the following determinations: whether a time of charging/discharging of the secondary battery has reached a predetermined time; whether a charging/discharging amount in the secondary battery has reached a predetermined amount; and whether a voltage per cell of the plurality of cells has reached a voltage V1 at a lower-limit state of charge in a range of capacity actually used; and a discharging controller for discharging the secondary battery until the voltage per cell reaches a voltage V3 that is higher than 1.0 V and is lower than the voltage V1 at the lower-limit state of charge when the memory effect determinator determines that the discharging memory effect has occurred.
