1. A battery monitoring and characterization system, the system comprising:
a plurality of electrodes integrated into a battery casing of a 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.
