Abstract

Disclosed is a secondary battery diagnosing technology capable of effectively diagnosing a state of a secondary battery using a charge and discharge signal of the secondary battery. The secondary battery diagnosing apparatus includes a memory unit configured to store a positive electrode reference profile and a negative electrode reference profile for charge or discharge of a reference battery; a voltage measuring unit configured to measure a voltage of a target battery during a charge or discharge process; and a processor configured to generate a charge and discharge measurement profile based on the voltage measured by the voltage measuring unit, compare a simulation profile obtained from the positive electrode reference profile and the negative electrode reference profile stored in the memory unit with the generated charge and discharge measurement profile, and determine a positive electrode adjustment profile and a negative electrode adjustment profile so that an error between the simulation profile and the charge and discharge measurement profile is within a predetermined level.
