Systems and methods for identifying thermal run-away events in a battery pack can include using sensing circuits made up of series- or parallel-linked thermistors to measure subsets of the individual battery cells in a battery pack. Using multiple sensing circuits, a monitoring system can positively identify when a threshold temperature of any single battery cell has been reached even though individual temperatures are not monitored, and can generate a signal indicative of a thermal run-away event based on the detected temperature.
