The present disclosure relates to the field of batteries. The battery pack management system includes a controller (11), an isolation unit (12), a plurality of battery pack management units (13), and a plurality of battery packs (14). The plurality of battery pack management units (13) are connected in series by a first daisy chain (16), and the plurality of battery pack management units (13) are also connected in series by a second daisy chain (17). The first daisy chain (16) transmits sampled data that is collected by the battery pack management units (13) from corresponding battery packs (14) and transmits control instructions of the controller (11). The second daisy chain (17) transmits a failure prompt signal which is generated by a battery pack management unit (13) that detects a failure. A first battery pack management unit (13) of the plurality of battery pack management units (13) connected in series and a last battery pack management unit (13) of the plurality of battery pack management units (13) connected in series are connected to the controller (11) through the isolation unit (12).</p></div>
