In high-power charging for battery-electric heavy-duty vehicles, predictability of charging sessions at public charging stations can be valuable for both vehicles and charging infrastructure. For drivers and fleet management, predictability enables reliable route planning under constraints. For charging stations, advance knowledge of charging demands supports efficient operation under grid limitations, including control of local energy storage systems or grid services. Furthermore, coordination of charging locations and timings across vehicles may help distribute grid load, balance charging station limitations, and reduce waiting time.
Booking-based charging has the potential to increase predictability while coordinating charging sessions across vehicles. While pilot implementations for booking of charging slots for heavy-duty vehicles exist, no booking system for high-power charging of heavy-duty vehicles has been broadly deployed. Furthermore, the design space for booking-based charging remains open, ranging from reservation-only systems, pricing mechanisms accounting for flexibility, market-based solutions encouraging beneficial distribution, to systems coordinating routing and charging.
In this work we will simulate separate routing and optimized charging scheduling for long-haul road transport vehicles, and analyse the differences in charging station load and constraints as well as vehicle routes and arrival times. Based on this, we discuss how alternative frameworks for booking-based charging influence vehicles and infrastructure.
