Embedded monitoring electrodes for battery health monitoring

A battery monitoring and characterization system, the system comprising:

• a plurality of electrodes integrated into a battery casing of a battery, wherein the plurality of electrodes is integrated into at least one of a side, a top, or a bottom of the battery casing of the battery;
• and
• a drive-sense circuit (DSC) operably coupled to a first electrode of the plurality of electrodes via a single line, wherein, when enabled, the DSC operably configured to:
• drive a signal to the first electrode via the single line and simultaneously sense the signal via the single line, wherein a change of a distance between the first electrode of the plurality of electrodes and a second electrode of the plurality of electrodes changes a capacitance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes;
• and
• generate a digital signal representative of a change of the capacitance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes, wherein:
• an increase of the distance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes corresponds to a decrease of the capacitance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes;
• and
• a decrease of the distance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes corresponds to an increase of the capacitance between the first electrode of the plurality of electrodes and the second electrode of the plurality of electrodes.
