A battery diagnosing apparatus, a battery pack, an electric vehicle and a battery diagnosing method are provided. The battery diagnosing apparatus according to the present disclosure is provided for a battery array including first to mth batteries (m is a natural number of 3 or more) connected in series. The battery diagnosing apparatus includes a measuring unit configured to detect voltage of each of the first to mth batteries, and a control unit configured to generate first to mth voltage profiles representing a voltage change history of each of the first to mth batteries during charging or discharging of the battery array. The control unit diagnoses the battery array by comparing each of first to (m-1)th comparison voltage profiles with a criterion voltage profile. The criterion voltage profile is one of the first to mth voltage profiles, and the first to (m-1)th comparison voltage profiles are remaining (m-1) voltage profiles other than the criterion voltage profile.
