For early prediction models, the velocity and current profile data were divided into small sections, followed by the same feature extraction and model development (velocity and current) process described above. We began training the early prediction models with 300-350 seconds of data and predicted the charge saving score at the end of 800 seconds of the trip. Subsequently, the training data was increased by 50 seconds, and the prediction step was repeated. This process continued until the training data reached the 800-second limit. Supplementary Figure and 8show collective MAPE results for early prediction models for all the time intervals.
