  • Publication number: 20220276314
    Abstract: A battery management apparatus is configured to diagnose a state of a battery cell based on a capacity-voltage differential profile. Specifically, the battery management apparatus diagnoses a state of the battery cell according to a change pattern of a peak associated with a positive electrode reaction area and a peak associated with an available lithium loss in the capacity-voltage differential profile. The state of the battery cell may be diagnosed in real time even while the battery cell is in operation. In addition, it is possible to independently diagnose whether the positive electrode reaction area of the battery cell is reduced and whether available lithium is lost.

  • Patent number: 11338699
    Abstract: An apparatus and method for determining electrode information of a battery including a positive electrode and a negative electrode, and a battery pack including the apparatus. The apparatus includes a sensing unit configured to measure a voltage and a current of the battery, and a processor. The processor generates a V-dQ/dV curve based on the voltage and the current of the battery. The V-dQ/dV curve indicates a relationship between V (the voltage of the battery) and dQ/dV (a ratio of an amount of change dQ of the remaining capacity to an amount of change dV of the voltage of the battery). The processor detects a plurality of feature points from the V-dQ/dV curve. The processor determines information associated with each of the first electrode and the second electrode as the electrode information based on the plurality of feature points.
