Abstract
Systems and methods for cell anomaly detection are provided. The disclosed systems and methods of cell anomaly detection may use a single circuit to detect both cell-open and imbalance conditions. Disclosed embodiments may incorporate a continuous or a sampled time system (i.e. cell anomaly detection is performed when an enable signal is active). An example embodiment includes receiving voltages of a plurality of cells of a battery pack; converting the received voltages to currents; determining a maximum current of the currents; determining whether at least one of the currents is anomalous; and reporting the at least one anomalous current as indicative of a bad cell.
