WIRELESS BATTERY MANAGEMENT SYSTEM WITH A CONTINUOUS BATTERY CELL MONITORING FUNCTION AND AN OPERATING METHOD THEREFOR

A wireless battery management system includes at least one cell monitoring unit (CMU) configured to monitor a status of at least one battery module including a plurality of battery cells, and a battery management unit (BMU) configured to manage the at least one CMU through wireless communication with the at least one CMU. The at least one CMU continuously monitors the status of the plurality of battery cells included in the battery module, and upon or based on detecting or determining an abnormal state in at least one battery cell, notifies the BMU of the abnormal state of the battery cell. Upon or based on receiving notification of the abnormal state of the battery cell from the CMU, the BMU transitions from a sleep mode to an active mode, and responds to the abnormal state of the battery cell.
