Field: Measurement (Instruments)
Classification: CPC G  H  Y | IPC G

Claim 16:
17. A battery characterization system comprising:
a drive-sense circuit (DSC) operably coupled to a terminal of a battery, wherein, when enabled, the DSC configured to:
receive a reference signal;
generate a monitoring signal that includes an AC (alternating current) component based on the reference signal, wherein the monitoring signal includes a DC component of at least one of 0 volts or 0 amps;
provide, during non-charging operation of the battery, the monitoring signal to the terminal of the battery via a single line and simultaneously to sense the monitoring signal via the single line, wherein sensing of the monitoring signal includes detection of an electrical characteristic of the battery that is based on a response of the battery to the monitoring signal; and
generate a digital signal representative of the electrical characteristic of the battery that is based on the response of the battery to the monitoring signal;

memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC and the memory, wherein, when enabled, the one or more processing modules configured to execute the operational instructions to:
generate the reference signal;
provide the reference signal to the DSC; and
process the digital signal to determine the electrical characteristic of the battery that is based on the response of the battery to the monitoring signal.
