To enable personalized recommendations for EV drivers, we not only consider the battery's absolute state of charge at a given time but also provide insights into potential battery savings from adjustments in driving decisions, such as route selection, charging frequency, and driving style, we introduce the term charge saving score, which represents the drop in SOC relative to a reference profile. This reference profile with constant maximum velocity on flat terrain is chosen. The equation for calculating the charge saving score is given below, where ∆ soc denotes the actual drop in SOC, and ∆ soc ref denotes the drop in SOC for the reference profile. To ensure a positive value, 1 is added to the result.
