Disclosed is a method for diagnosing a battery system (BAT) having a hierarchical structure including a lower-level battery device (LB) and a higher-level battery device (HB). The method includes: determining, by a processor (100), first and second charge/discharge test environments providing complementary characteristics for performance degradation of the higher-level battery device (HB) exhibits by performing a charge/discharge test with respect to the higher-level battery device (HB); performing, by the processor (100), a charge/discharge test with respect to the lower-level battery device (LB) under the first and second charge/discharge test environments to determine whether a test result matches the complementary characteristics under the first and second charge/discharge test environments; and deriving, by the processor (100), optimal operating conditions of the battery system (BAT) in which the complementary characteristics under the first and second charge/discharge test environments are removed, upon determining that the test result of the charge/discharge test with respect to the lower-level battery device (LB) matches the complementary characteristics under the first and second charge/discharge test environments.
