  "textContent": "A system for assessing health of a cell group within a module of a battery pack includes a controller having a processor and tangible, non-transitory memory on which instructions are recorded. One or more sensors are configured to obtain a series of respective average cell group voltages at different stages. The controller is adapted to obtain a measured voltage (V) of the cell group at a calibration event occurring after the third stage. The controller is adapted to calculate a predicted voltage (V) of the cell group based in part on a sum of a disparity factor (ΔV) and a third stage cell group voltage (V). The cell group is controlled based at least partially on a difference between the measured voltage (V) and the predicted voltage (V).",
