Abstract
Apparatus for providing a continuous indication of battery state-of-charge under load in a system in which the battery is subject to varying load conditions. The apparatus stores a value representative of battery open circuit terminal voltage and reduces the stored value while the battery is loaded at a rate proportional to the difference between the stored value and a scaled value of actual battery terminal voltage. If the scaled value exceeds the stored value, the stored value is increased to a value corresponding to the scaled value.
