description A battery diagnosis apparatus includes a battery monitor to detect a voltage of each of a plurality of battery cells included in a battery module; and a control circuit to determine a latest value of a first voltage deviation indicating a difference between a voltage behavior of each battery cell and an average voltage behavior of the plurality of battery cells over a relaxation period from a start time of a resting event.
