Abstract
The battery monitoring techniques described herein use a self-characterizing wireless monitor coupled to a battery to monitor different properties of the battery. The wireless monitor may measure, among other things, an alternating current frequency response (ACFR) of the battery. To accomplish this, the wireless monitor may generate and inject a stimulus signal into the battery, and the monitor may then synchronously measure the corresponding impedance response of the battery.
