ABSTRACT:
A method and apparatus for continuously monitoring the remaining ampere hours of charge of a rechargeable battery. The invention utilizes a voltage monitoring system actuated by a current monitoring system to measure battery terminal voltage only when current discharge attains a predetermined level. The value of terminal voltage measured is stored and applied to an indicating device to yield a constant readout of battery state of charge.
