description Disclosed examples include systems and methods for determining an internal short condition in a battery. The method includes computing an estimated current value based on a measured battery voltage, a measured battery current, a measured battery temperature, and a model of the battery that includes steady state characteristics of the battery and transient characteristics of the battery. The method further includes computing an internal short current value according to the measured battery current and the estimated current value, and determining if a battery short condition exists according to the internal short current value.
