1. A battery characterization system, the system comprising:
a battery;
a configurable impedance circuit operably coupled to the battery;
a drive-sense circuit (DSC) operably coupled to the configurable impedance circuit, wherein, when enabled, the DSC configured to:
generate a charge signal that includes an AC (alternating current) component;
provide the charge signal to the configurable impedance circuit via a single line and simultaneously to sense an effect on the charge signal via the single line that is based on an electrical characteristic of at least one of the configurable impedance circuit and the battery; and
generate a digital signal representative of the electrical characteristic of the at least one of the configurable impedance circuit and the battery;
memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC, the configurable impedance circuit, and the memory, wherein, when enabled, the one or more processing modules is configured to execute the operational instructions to select an impedance value within the configurable impedance circuit to facilitate charging of the battery by the charge signal that is provided from the DSC via the configurable impedance circuit to the battery based on the digital signal.
