The global shift towards sustainable transportation has led to a surge in the adoption of electric and fuel cell
vehicles. This paper introduces a novel energy management approach for the charging stations that serve both
battery electric buses and fuel cell buses. Addressing the challenge of guaranteeing enough energy for all buses in the system, a novel priority charging approach is adopted. This approach involves a sophisticated control system that predicts which buses will receive the required energy to complete their designated routes. Minimizing the cost of the charging energy while ensuring adequate charging for buses across their entire routes without energy interruption is pursued. Six scenarios have been studied and compared, comprising a standalone and grid connected photovoltaic-based charging station, considering all buses are either battery electric buses, fuel cell
buses or a hybrid combination of both. The obtained results show that the grid-connected with battery electric
buses gives the lowest energy cost of $0.0162/kWh. Furthermore, the study highlights the potential of grid connected charging station accommodating both electric and fuel cell buses striking a balance between cost effectiveness and fleet diversity.
