Abstract: disclosed is an apparatus and method for managing an open circuit voltage (ocv)-state of charge (soc) profile of a battery. the apparatus according to the present disclosure includes a storage means to store a plurality of ocv-soc profiles having an overlapping zone in which the ocv-soc profiles overlap in a predetermined soc range; and a control means coupled to the storage means. the control means is configured to calculate a partial capacity of the battery in the soc range of the overlapping zone during charging or discharging of the battery, determine a reduction ratio of the current partial capacity to the partial capacity of the battery at beginning of life (bol), select the ocv-soc profile corresponding to the reduction ratio among the plurality of ocv-soc profiles, change the current ocv-soc profile to the selected ocv-soc profile, and control the charge or discharge of the battery using the changed ocv-soc profile.
