A Scalable Charging-Station Model for Electric Vehicle Traffic Simulations in SUMO

This preprint presents a modular charging-station model for microscopic traffic simulations in SUMO. The proposed architecture separates charging operations from the main road through dedicated access lanes, internal circulation and reservable parking areas. An automated integration procedure and a series of capacity stress tests evaluate station performance under varying demand levels, identifying queue formation, entrance saturation and internal circulation bottlenecks.
