Patent ID: 11971454
Assignee: ZITARA TECHNOLOGIES, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 8:
9. A method for determining whether a battery is operating in an anomalous condition comprising:
measuring a timeseries of sensor data comprising at least one of current, voltage, or temperature;
estimating a timeseries of a local property of the battery using the timeseries of sensor data comprising:
detecting a series of current jumps in the timeseries of sensor data, wherein each current jump of the series of current jumps exceeds a threshold current jump amplitude, wherein the threshold current jump amplitude is about 0.1 A/s; and
calculating a resistance of the battery at each of the current jumps of the series of current jumps; and

classifying whether the battery is operating in the anomalous condition using a statistical test of the timeseries of the local property of the battery;, wherein the anomalous condition comprises a cell disconnection within the battery.
