Abstract: An anomaly detection method for an energy storage system includes receiving multiple sensing data retrieved from an electronic component of the energy storage system; inputting the multiple sensing data to a temperature prediction model; respectively receiving the multiple sensing data of same type and computing multiple time-series features related to the type based on the multiple sensing data of the type by each of a plurality of model encoders; outputting the multiple time-series features of each type to a reweighting model; computing a predicted temperature feature based on the multiple time-series features by the reweighting model and outputting the predicted temperature feature to a model decoder; reconstructing a predicted temperature feature by the model decoder to generate a predicted temperature of the electronic component; and determining whether the electronic component operates abnormally by estimating an error between the predicted temperature and a current temperature.
