Claim 0:
1. A battery characterization system comprising:
a drive-sense circuit (DSC) connected via a single line to a terminal of a battery, wherein, when enabled, the DSC configured to:
generate a monitoring signal that includes an AC (alternating current) component based on a reference signal;
provide, during non-charging operation of the battery, the monitoring signal to the terminal of the battery via the 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 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.
