Assignee: ZITARA TECHNOLOGIES, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. A system for detecting a battery anomaly in a battery comprising:
at least one of:
a current sensor configured to measure a current dataset associated with the battery;
a voltage sensor configured to measure a voltage dataset associated with the battery; or
a temperature sensor configured to measure a temperature dataset associated with the battery;

a model operable to predict a local property dataset of the battery using the at least one of the current dataset, the voltage dataset, or the temperature dataset;
a classifier configured to classify whether the battery is operating in an anomalous condition based on the estimated local properties of the battery, wherein the classifier is operable in:
a steady state mode wherein the classifier is operable to classify the anomalous condition as a thermal anomaly or an electrical short using a local property dataset derived from steady state readings of the at least one of current, voltage, or temperature; and
a jump change mode wherein the classifier is operable to classify the anomalous condition as a battery cell disconnection or a loss of thermal connection using a local property dataset jump changes in the at least one of current, voltage, or temperature, wherein the jump changes are at least about 0.1 A/s to classify the battery cell disconnection.
