Abstract
A battery testing apparatus including a memory unit configured to store profile data of a battery; an interface unit configured to receive a signal designating a specific future date after the beginning of life of the battery at which a lowest SOC according to degradation of the battery is to be predicted; and a processor connected to the memory and interface units to communicate therewith. The profile data includes first, second and third look-up tables in which open circuit voltages for each SOC from the battery in the beginning of life, closed and open circuit voltages for each SOC from an equivalent circuit of the battery in the beginning of life, and resistance increase rates predetermined for each use period, are respectively recorded. The processor predicts the lowest SOC at the specific date according to the degradation of the battery with reference to the first, second and third look-up tables.
