Abstract
A method and apparatus for detecting a bad cell in a storage battery having a plurality of cells as provided. Input circuitry electrically couples to first and second terminals of the storage battery. Voltage measuring circuitry coupled to the input circuitry provides a voltage output related to a voltage potential between the first and second terminals of the storage battery. Conductance measuring circuitry coupled to the input circuitry provides a conductance output related to conductance of the storage battery. Voltage and conductance comparison circuitry compares the measured voltage and conductance to references and provide outputs. Output circuitry provides a bad cell output based upon the results of the comparisons.
