Commercial EV Fleet and Battery Storage Dataset: Simulation Data for Vehicle-to-Business Applications

Dataset Documentation This repository contains simulation data from research investigating the synergies and substitutions between bidirectional battery electric vehicle fleets and stationary battery storage systems in commercial applications. The simulation data evaluates three use cases with varying fleet sizes, stationary battery storage capacities, and charging strategies to analyze economic and technical performance indicators. Repository Structure The dataset is organized by three main use cases representing different commercial applications: Health Social Services Manufacturing Office Each use case contains the following subdirectories: Charging_Strategy Contains detailed simulation results for different charging strategies and configurations.
