Charging / discharging controller, battery pack, vehicle and charging / discharging control method

摘要

Problem to be solved: to provide a charge discharge control apparatus and a charge / discharge control method for appropriately determining the capacity drop of the battery due to the deviation from the reference state of the positive electrode potential and the negative electrode potential, and appropriately recovering the capacity of the lowered battery.In the charging / discharging control apparatus and charge / discharge control method of the embodiment, information related to the positive potential and the negative electrode potential is obtained for each of the one or more batteries, and it is determined whether or not the deviation from the reference state of the positive potential and the negative electrode potential exceeds the prescribed range.In the charging / discharging control apparatus and the charge / discharge control method, the charging depth of the recovery target battery is maintained at a recovery time in the recovery range based on at least the recovery target battery which is a battery in which the positive potential and the negative electrode potential are deviated from the reference state beyond the prescribed range.Diagram
