1. A battery monitor system for multi-cell batteries comprising:

  • continuous scanner means for sequentially and repeatedly establishing contact across individual cells of the battery;

    detector means coupled to said scanner means for evaluating the electrical condition of the cell being connected to said scanner means;

    means for comparing the electrical condition of the cell with a preselected range of voltages, said comparing means emitting an electrical signal when said electrical condition is outside said predetermined range; and

    alarm means controlled by said electrical signal for producing an alarm signal upon receiving said electrical signal from said comparing means;

    said scanner means includes a pulse generator generating uniformly timed pulses;

    a counter means for counting said uniformly timed pulses, said counter means having outputs equal in number to the number of cells to be monitored; and

    a group of relays actuated by one of said output counter means, said relays being operable to provide individual electrical connections to one of said battery cells.
