To provide a charge/discharge control device and a charge/discharge control method for appropriately determining a decrease in battery capacity caused by deviation of a positive electrode potential and a negative electrode potential from a reference state, and appropriately recovering the decreased battery capacity.SOLUTION: In a charge/discharge control device and a charge/discharge control method, information related to a positive electrode potential and a negative electrode potential is acquired for each of one or more batteries, and it is determined whether deviations of the positive electrode potential and the negative electrode potential from reference states thereof go beyond specified ranges. In the charge/discharge control device and the charge/discharge control method, at least based on existence of a recovery target battery which is a battery in which the deviations of the positive electrode potential and the negative electrode potential from the reference states thereof go beyond the specified ranges, the depth of charging of the recovery target battery is held for a specified time within a recovery holding range.SELECTED DRAWING: Figure 6
