1. A processor-implemented method comprising:
based on battery data measured by a battery and a battery model of the battery, determining a detection parameter value used for detecting a short circuit of the battery and a variation factor value correlated with the detection parameter;
using the variation factor to extract a reference value corresponding to the detection parameter value from a reference data set; and
determining whether a short circuit of the battery has occurred based on a result of comparing the detection parameter value with the reference value.
