BATTERY MANAGEMENT APPARATUS AND METHOD

A battery management apparatus according to an embodiment of the present disclosure 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. According to an aspect of the present disclosure, there is an advantage in that the state of the battery cell may be diagnosed in real time even while the battery cell is in operation. In addition, there is an advantage in that it is possible to independently diagnose whether the positive electrode reaction area of the battery cell is reduced and whether available lithium is lost.
