Abstract
Official abstract text for this publication.
A system for estimating battery state of charge (SoC) includes evaluating a battery model to produce an estimated battery voltage using a previously produced SoC. Current and voltage measurements are combined with the estimated battery voltage to produce a present battery SoC. The battery model may be updated by taking battery measurements when certain conditions occur.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for estimating a battery state of charge (SoC) of a battery comprising: a processor providing a representation of a battery model, the battery model comprising an open circuit voltage (OCV) component and an equivalent series resistance (R series ) component; the processor acquiring a current measurement of the battery; the processor acquiring a voltage measurement of the battery; the processor computing a present estimate of the battery SoC u…
