  "textContent": "A method for detecting an abnormal battery cell includes periodically generating a voltage value and a current value for each of battery cells, updating, in real time by using an adaptive filter, a G parameter value and an H parameter value of each of battery cells, based on the voltage value and the current value, calculating a representative G parameter value and a representative H parameter value, and determining whether each of the battery cells is an abnormally deteriorated cell based on the G parameter value and the H parameter value of each of the battery cells, the representative G parameter value, and the representative H parameter value. The G parameter indicates sensitivity of voltage with respect to a change in current of the battery cell, and the H parameter indicates an effective potential determined by a local equilibrium potential distribution and a resistance distribution in the battery cell.",
