A battery state diagnosis apparatus includes a processor configured to extract battery impedance by obtaining voltage and current signals outputted from a battery management system of an electric vehicle, removing noise by performing first signal processing on the voltage and current signals outputted from the battery management system, and extracting a frequency characteristic by performing second signal processing on the voltage and current signals from which the noise has been removed, and a storage configured to store data and algorithms driven by the processor.
