ABSTRACT:
The terminal current of a main secondary battery is continuously monitored throughout charging and discharging by a system having a monitor cell, such as a metal gas battery, and having circuitry for conforming monitor cell terminal current in sense, and proportionally in magnitude, to the main battery terminal current. Apparatus responsive to the monitor cell state of charge may provide sensible output indication of main battery state of charge or control charging/discharging of the main battery.
