Abstract
Electric vehicles (EVs) hold promises to revolutionize transport decarbonization, but face challenges such as grid constraints, high costs, and long charging times. In this context, battery swapping emerges as a solution, offering scheduled charging, quick replacements, and utilizing station batteries for energy services. This study assesses the viability of supplying energy services to major consumers through battery swapping stations. It highlights the advantages of integrating charging and swapping stations to address challenges in widespread EV adoption, focusing on external charging stations. After a first assessment, which gathered some key data like hourly energy demand, electricity costs and grid fees, a detailed analysis is conducted to identify daily or seasonal trends in demand for a specific case study. In addition, an optimization procedure for the case study has been realized to minimize the annual energy cost. The results demonstrate a noteworthy reduction in peak demand, amounting to less than half of the original combined peak demand. In addition, thanks to the exploitation of the spread in the electricity costs during the day and the peak capacity reduction, annual economic savings reach more than € 80’000 in total. This underscores the efficacy of a battery swapping system not only in optimizing peak demand but also in capitalizing on cost differentials in electricity pricing, thereby contributing to considerable economic benefits.
