Claims21
-14. (canceled)
A battery diagnosis apparatus comprising one or more processors configured to:
- obtain time-series data regarding a voltage of each of a plurality of battery cells;
- calculate a moving average and a standard deviation for a reference unit from the time-series data of each battery cell, and
- diagnose whether each battery cell is abnormal based on the moving average and the standard deviation.
A battery diagnosis method comprising:
- obtaining time-series data regarding a voltage of each of a plurality of battery cells;
- calculating a moving average and a standard deviation for a reference unit from the time-series data of each battery cell;
- and
- diagnosing whether each battery cell is abnormal based on the moving average and the standard deviation.
