Abstract

Techniques are provided for generating an internal short circuit prediction of a battery cell. In one embodiment, the techniques involve receiving feature measurements of a plurality of cells, determining a snapshot moving average of the feature measurement of each of the plurality of cells based on a corresponding measurement window, determining a health indicator of each of the plurality of cells based on the respective snapshot moving averages, ranking a plurality of health indicators of the respective plurality of cells, wherein the plurality of health indicators is ranked by magnitude, determining a short circuit threshold value based on a second-ranked health indicator, and upon determining that a first-ranked health indicator exceeds the short circuit threshold value, generating a prediction of a short circuit in a cell corresponding to the first-ranked health indicator.
