Classification: CPC G  H  Y | IPC G

Claim 5:
6. The battery characterization system of claim 2, wherein, when enabled, the one or more processing modules is further configured to execute the operational instructions to:
generate the reference signal to include a frequency sweep of the AC component of the monitoring signal such that the AC component of the monitoring signal includes different respective frequencies at or during different respective times including a first frequency at or during a first time and a second frequency different than the first frequency at or during a second time as varying across a predetermined frequency range; and
at or during the different respective times, process the digital signal representative of the electrical characteristic of the battery that is based on the response of the battery to the AC component of the monitoring signal that varies across the different respective frequencies of the predetermined frequency range to determine respective values of the electrical characteristic of the battery across the different respective frequencies and to generate spectrum analysis (SA) information of the battery that is based on a signal response of the battery to the frequency sweep of the AC component of the monitoring signal.
