Claim 18:
19. The method according to claim 17,
wherein determining a deterioration-biased electrode comprises:
determining that a negative electrode of the secondary battery is the deterioration-biased electrode in response to a ratio of a section of the deterioration diagnosing SOC section for which the deterioration diagnosing resistance ratio is greater than the reference deterioration diagnosing resistance ratio being equal to or greater than a threshold value, and
determining that the positive electrode is the deterioration-biased electrode in response to a ratio of a section of the deterioration diagnosing SOC section for which where the deterioration diagnosing resistance ratio is smaller than the reference deterioration diagnosing resistance ratio being equal to or greater than the threshold value.
