Battery management system and method for controlling the same

Abstract

The present disclosure relates to a battery management system and a method for controlling the same. The battery management system according to an embodiment of the present disclosure may include an alarm module configured to provide an alarm in a designated manner; an electrochemical impedance spectroscopy (EIS) measurement module configured to measure an EIS of a secondary battery; and a processor configured to receive an EIS measurement result from the EIS measurement module, calculate real intercepts of impedance values for the secondary battery based on the received EIS measurement result, determine whether the secondary battery is abnormal based on the calculated real intercepts, and control the alarm module to provide an alarm notifying that the secondary battery is abnormal if there is an abnormality in the secondary battery as a result of the determination. The present disclosure may improve the accuracy and/or efficiency in abnormality detection of the secondary battery.
