Internal short circuit prediction generation

A system for predicting a circuit condition of a power system of a vehicle, comprising:

• a processor;
• and
• memory or storage comprising an algorithm or computer instructions, which when executed by the processor, performs an operation comprising:
• receiving feature measurements of a plurality of cells of the power system;
• determining a snapshot moving average of a 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 a 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;
• 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;
• and
• controlling an operation of the vehicle to mitigate an impact of the short circuit in the cell corresponding to the first-ranked health indicator by preventing overheating of the cell corresponding to the first-ranked health indicator and transmitting an alert to a repair facility identifying the cell corresponding to the first-ranked health indicator as needing one of repair and replacement.

A non-transitory computer-readable storage medium having a computer-readable program code embodied therewith for predicting a circuit condition of a power system of a vehicle, the computer-readable program code executable by one or more computer processors to perform an operation comprising:

• receiving feature measurements of a plurality of cells of the power system;
• determining a snapshot moving average of a 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 a 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;
• 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;
• controlling an operation of the vehicle to mitigate an impact of the short circuit in the cell corresponding to the first-ranked health indicator by preventing overheating of the cell corresponding to the first-ranked health indicator and transmitting an alert to a repair facility identifying the cell corresponding to the first-ranked health indicator as needing one of repair and replacement;
• and
• reiterating the operation continuously as the vehicle is operated and continuously adjusting the operation of the vehicle to mitigate the impact of the short circuit in the cell corresponding to the first-ranked health indicator.
