ABSTRACT:
Defective battery cells are detected by individually monitoring the voltage utput therefrom, which characteristically becomes abnormal when the defective condition occurs. Each cell is independently referenced to a common ground by its voltage monitoring device which drives a level sensing comparator that generates a control signal when the output voltage from that cell becomes abnormal. This control signal drives at least one switch to indicate when the defective condition occurs.
