1. A power storage system for enhanced performance compensation of a storage battery, the power storage system comprising:
a battery management system configured to control charging and discharging of the storage battery, and
an apparatus comprising:
at least one memory configured to store one or more instructions; and
at least one processor configured to execute the one or more instructions to:
acquire a criteria value that is a first performance value of the storage battery at a criteria time;
acquire a target value that is the first performance value of the storage battery at a determination time;
acquire usage method data indicating a usage method of the storage battery from the criteria time to the determination time;
compute a predicted range of the first performance value at the determination time based on the criteria value, the usage method data, and a time elapsed from the criteria time to the determination time; and
determine whether the storage battery is experiencing abnormal deterioration based on whether the target value is outside the predicted range,
wherein performance of the storage battery is selectively compensated for deterioration based on the determination of the apparatus.
