Abstract
Techniques are provided for reference electrode-based battery imbalance diagnosis. In one embodiment, the techniques involve determining a state of health of a cell group, determining a state of health of a cell of the cell group, determining a cell imbalance of the cell group based on a comparison of the state of health of the cell group and the state of health of the cell, and generating an alert signal or a control signal based on the cell imbalance.
