Device incorporating a battery, method for obtaining voltage, current and temperature measurements of a battery, method for estimating the health status of a battery using such measurements

Abstract

A method is described for obtaining voltage, current, and temperature measurements of a battery embedded in an electronic device. The device includes battery-powered components, including at least one processor assembly, and sensors associated with the battery. The process is implemented by the processor assembly. It involves driving one or more of the device's components to generate a current excitation signal from the battery over a time interval corresponding to the battery's charge and / or discharge cycle. Voltage, current, and temperature measurements of the battery are obtained via sensors in response to this excitation signal. These measurements are used to update a parametric model of the battery, which can be used, for example, to assess the battery's health. [Fig. 5]
