Battery Diagnostic Device And Method

Abstract: A battery diagnostic device according to an embodiment of the present invention may comprise: a data acquisition unit configured to acquire a resistance value and a voltage value of a battery; a profile generation unit configured to generate a profile indicating a correspondence relationship between the resistance value and the voltage value of the battery, which are acquired by the data acquisition unit; and a control unit configured to set a reference range in the profile received from the profile generation unit, and diagnose whether the battery is abnormal, on the basis of a result of comparing the resistance value of the battery with the reference range.
