Comparative analysis of electric vehicle charging infrastructure in Spanish multi-unit residential buildings

The growing adoption of electric vehicles (EVs) necessitates the development of efficient and cost-effective charging infrastructure, particularly in multi-unit residential buildings. This study presents a techno-economic analysis of different EV charging installation schemes in Spain, focusing on the impact of load management systems (LMSs). The analysis evaluates the feasibility of collective and individual metering schemes, comparing their technical and economic implications. Results indicate that LMS significantly reduces peak power demand, lowers infrastructure costs, and optimizes electricity bills by distributing energy consumption more effectively. Additionally, regulatory considerations, installation challenges, and consumer adoption factors are examined to propose best practices for scalable and sustainable EV charging integration. The findings provide valuable insights for policymakers, urban planners, and building administrators seeking to facilitate EV adoption while minimizing economic and technical barriers.
