Abstract: A method and apparatus with battery short circuit detection are included. In one general aspect, a processor-implemented method includes, 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.

Abstract: Methods and systems for performing advanced analytics based on which features are active by correlating information based on temporal identifiers in feature databases. The method includes receiving a request to change a feature, determining metadata information for the feature, which may include a temporal indicator, a performance metric and a configuration of activation states, and generating a feature change record based on this metadata. The method includes receiving a request to determine a second performance metric, processing the request by determining a second feature change record, determining a configuration and generating a recommendation for display.
