Implementação de sistemas de carregamento de veículos elétricos em uma edificação comercial

Abstract

The growing expansion of electric mobility has increased the need to adapt the electrical infrastructure of Brazilian buildings to support electric vehicle charging systems, creating new challenges related to electrical system sizing, safety, compliance with technical standards, and the integration of charging infrastructure into existing electrical networks. In this context, this study aimed to analyze the technical and structural challenges involved in implementing electric vehicle charging systems in commercial buildings through a case study conducted at Shopping Eldorado Campo Grande, where ten charging stations were installed. The research adopted a qualitative and quantitative approach based on a literature review, field data collection, assessment of the existing electrical installation, electrical system sizing, and compliance analysis with applicable technical standards. The results demonstrated that the existing electrical infrastructure had sufficient capacity to supply the additional demand imposed by the charging stations without requiring the replacement of the existing transformer. Furthermore, the study highlighted the importance of proper sizing of protection systems, electrical distribution infrastructure, and careful planning during the execution phase. Challenges related to equipment logistics, operational constraints during installation, coordination among multidisciplinary teams, and infrastructure implementation costs were also identified. It is concluded that the implementation of charging systems in existing buildings is technically feasible when supported by detailed assessments of the electrical installation and comprehensive technical planning during both the design and construction phases. Future research should address new fire safety requirements for electric vehicle supply equipment, the integration of photovoltaic generation systems with charging infrastructure, and operational and economic performance analyses considering the continuous growth of electric mobility.
