A system for evaluating a battery assembly includes a sensing device configured to acquire parameters related to a group of cells of the battery assembly, and a diagnostic module. The diagnostic module is configured to perform estimating a state of charge (SOC) value for the group of cells based on measurements performed during a selected time window, calculating a statistical value related to the estimated SOC value for the group of cells, assigning the estimated SOC value to a selected bin of a plurality of SOC bins based on the statistical value, each SOC bin of the plurality of SOC bins including a subset of a range of SOC values, calculating a deviation of each SOC value in the selected bin relative to a plurality of SOC values in the selected bin, and determining whether the group of cells is healthy based on the deviation.
