20100173183 | Systems and Methods of Battery Cell Anomaly Detection - 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. | 07-08-2010 |
20100225300 | Systems and Methods of Overvoltage and Undervoltage Detection - Systems and methods for overvoltage and undervoltage detection are provided. The disclosed systems and methods of overvoltage and undervoltage detection may be implemented with a fully differential circuit that includes a coarse comparator and a band gap based fine comparator. The coarse comparator may determine if the battery is closer to an OV condition or an UV condition. Based on the output of the coarse comparator, the trip point of the fine comparator is adjusted. The outputs of both comparators are pull-up circuits whose output is decoded to determine if an OV or a UV condition has occurred. The disclosed systems and methods of overvoltage and undervoltage detection accomplish valid circuit outputs even when the voltage across the battery reduces to zero volts. This may be achieved by using an active low signal for the UV condition and an active high signal for the OV condition. Thus, when the battery voltage goes to zero, the circuit evaluates to the correct output. | 09-09-2010 |

20110012605 | CURRENT BASED OVERVOLTAGE AND UNDERVOLTAGE DETECTOR - With batteries or cells, particularly lithium ion cells, it is important to determine when one or more cells have entered a fault condition (i.e., overvoltage or undervoltage).

Here, a circuit is provided that reduces the number of bandgap circuits and reduces the number of high voltage components, reducing the area consumed and reducing the overall cost of production compared to conventional circuits. | 01-20-2011 |
