  "textContent": "Cell group voltages for battery cell groups of a battery module are received from voltage sensors. Cell group currents for the battery cell groups are received from current sensors. Open circuit voltages are generated for each of the battery cell groups based on the cell group voltages and the cell group currents. A normalized open circuit voltage of a first battery cell group of the battery cell groups is generated based on the open circuit voltages of the battery cell groups. A normalized cell group voltage of the first battery cell group is generated based on the cell group voltages of the battery cell groups. An assessment of the normalized open circuit voltage and the normalized cell group voltage of the first battery cell group is performed to determine whether there is an internal soft short in the first battery cell group.",
