Abstract: A battery characterization system includes a drive-sense circuit (DSC), memory that stores operational instructions, and processing module(s) operably coupled to the DSC and the memory. Based on a reference signal, the DSC generates a charge signal, which includes an AC (alternating current) component, and provides the charge signal to a terminal of a battery via a single line and simultaneously to senses the charge signal via the single line to detect an electrical characteristic of the battery based on a response of the battery. The DSC generates a digital signal representative of the electrical characteristic of the battery. The processing module(s), based on the operational instructions, generate the reference signal to include a frequency sweep of the AC component of the charge signal (e.g., different frequencies at different times or multiple frequencies simultaneously) and processes the digital signal to characterize the battery across the different respective frequencies and generate spectrum analysis (SA) information of the battery.
