BATTERY MONITOR
First Claim
Patent Images
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.

Abstract
A self-monitoring system for batteries which continuously scans individual cells in succession and signals faulty cells at intervals determined by the sequencing rate and the number of cells being monitored.
