Abstract

See full text

In a preferred embodiment, a metering system for measuring and indicating the state of charge of an electrical storage battery, including: apparatus for storing a numerical value indicative of the state of charge of the battery and for providing an output voltage signal representative thereof; apparatus for detecting the terminal voltage of the battery, coupled to the apparatus for storing, and being operable to generate a function of the battery terminal voltage which is a substantially proportional fraction of the terminal voltage and to provide an input to the apparatus for storing if the function is below a threshold variable reference voltage signal; apparatus for receiving the output voltage signal and for generating the variable reference voltage signal therefrom, the variable reference voltage signal being lowered as a function of the output voltage signal as the output voltage signal indicates progressively lower states of charge; and apparatus for measuring the level of current drawn from the battery and adjusting the apparatus for receiving and generating, in proportion to the current level, such that the variable reference voltage signal will be greater or lesser depending on the current level.
