Design requirements for aEVCS

Abstract

This study investigates the dynamic behavior of electric vehicle (EV) inlets under various real-world load scenarios to contribute to the design requirements of automated EV charging systems (aEVCS). Inlet movements were tracked using a camera system in combination with AprilTag markers during typical usage scenarios such as passenger boarding and alighting, as well as cargo loading and unloading. The results show that while translational displacements generally remain within the limits defined by ISO 5474-5, rotational movements, especially in smaller vehicles, often exceed these thresholds. The findings underscore the impact of vehicle type and inlet location on displacement behavior, suggesting that current standards require refinement to better reflect real-world variability.
