  • Publication number: 20220155371
    Abstract: An apparatus and method for diagnosing a failure of a switch unit included in a multi battery pack. The magnitude of a pack current flowing from each of battery packs connected in parallel to a load is measured, a battery pack whose pack current has a magnitude smaller than the average value by a threshold value or more is identified, and it is determined that an open failure occurs at the switch unit included in the identified battery pack, and the information of the battery pack including the switch unit at which the open failure occurs is output. The internal resistance of each battery pack may be statistically analyzed in order to more accurately diagnose the failure at the switch unit. Thus, an open failure of switch units included in battery packs connected in parallel may be easily and reliably diagnosed in a statistical viewpoint.

  • Publication number: 20220140620
    Abstract: Disclosed is an apparatus and method for balancing battery packs connected in parallel. If the pack voltage deviation of the first to nth battery packs is greater than the first threshold value, a battery cell having a higher voltage than the pack balancing target voltage set according to a preset criterion among the voltages of all cells is discharged to perform pack balancing for each battery pack and if the pack voltage deviation is equal to or smaller than the first threshold value, a battery cell having a higher voltage than the cell balancing target voltage set according to a preset criterion among the voltages of the cells included in a battery pack having a cell voltage deviation greater than the second threshold value is discharged to perform cell balancing for each battery pack.
