ABSTRACT:
Various systems and methods for determining micro-shorts are disclosed. For example, some embodiments of the present invention provide battery systems including a determination of potential micro-shorts based on rate of change of state of charge. Such battery systems include: a battery, a processor, and a computer readable medium. The computer readable medium includes instructions executable by the processor to: determine a rate of change of the state of charge of the battery; compare the rate of change of the state of charge of the battery against a threshold; and indicate a potential failure where the result of the comparison is beyond the threshold.
