Abstract
A battery diagnosing technology capable of effectively diagnosing a state of a secondary battery using a charge and discharge signal extracted from the secondary battery, including memory to store a positive electrode reference profile and a negative electrode reference profile for charge or discharge of a reference battery, a voltage sensor to measure a voltage of a target battery during a charge or discharge process, and a processor to generate a plurality of charge and discharge measurement profiles based on voltages measured at a plurality of different time points, compare each of the generated charge and discharge measurement profiles with a simulation profile obtained from the positive and negative electrode reference profiles, and determine positive and negative electrode adjustment profiles for each of the generated charge and discharge measurement profiles so that an error between each charge and discharge measurement profile and the simulation profile is within a predetermined level.
