Original Abstract Submitted
a battery diagnosing apparatus includes a resistance measuring unit to measure an internal resistance of each of battery modules including one or more battery cells, and a control unit to receive resistance information about the internal resistance of each of the battery modules from the resistance measuring unit. the control unit sets a first resistance section that includes the internal resistance of each of the battery modules. the control unit sets a second resistance section that includes the internal resistance of some of the battery modules that belongs to the first resistance section but having the internal resistance less than a predetermined amount than those included in the first resistance section, and diagnoses a state of a battery module of which the internal resistance belongs to both the first resistance section and the second resistance section as a normal state among the battery modules.
