1. A system for monitoring a plurality of electrochemical cells comprising:
- switch means;
multiplexer means for monitoring signals indicative of the cell voltage levels of a plurality of cells,selection means for coupling selected ones of the monitored signals to the switch means at respective times, andmeans for momentarily operating the switch means during a portion of each of the respective times to apply the selected signal to a measuring circuit,whereby the switch means is used to apply a plurality of cells to the measurement circuit as different signals are selected by the multiplexer.
