1. A method for monitoring a battery using a processor-based system, comprising the steps of:

  • receiving a temperature value measured from the battery in the system;

    receiving a temperature differential value from the battery in the system;

    receiving a state-of-charge (SoC) value measured from the battery in the system;

    processing at least one of the (a) temperature value and (b) temperature differential value, together with the SoC value to determine if the battery is approaching a failure condition prior to an actual failure condition, the failure condition comprising a battery short resulting from one of an overcharge condition and an overdischarge condition; and

    transmitting a warning signal if the processing step determined that a failure condition is approaching.
