Abstract
Various systems and methods for determining potential battery failure are disclosed. For example, some embodiments of the present invention provide battery systems that include a battery, an embedded processor and a computer readable medium. The computer readable medium includes instructions executable by the embedded processor to measure at least one characteristic of the battery; to calculate a rate of change of internal impedance of the battery based at least in part on the at least one characteristic of the battery; and to determine a potential failure condition based on the rate of change of internal impedance of the battery.
