Secondly, we note that at the 300-650s time interval, there is a slight decrease in MAPE values, likely due to the availability of additional trip information, leading to more accurate predictions. Specifically, the MAPE values for velocity and current model 2 decrease by 1.8% and 1.2%, respectively, between the 300-350s and 300-650s early prediction intervals. Given the relatively short trip duration (800 seconds) and a small SOC drop, these results remain valid and significant. This means that the 300-350s time window can still be used for early estimations, as it provides meaningful insights into the trip without requiring a longer observation window. This suggests that either current or velocity data from the initial few hundred seconds is sufficient for accurately estimating the charge usage score, as it effectively captures the driving conditions representative of the entire trip.
