Análise de viabilidade para substituição de carregadores convencionais por um carregador rápido em estação coletiva de recarga veicular

Abstract

Electric mobility has been consolidated as a viable and sustainable alternative for the decarbonization of the transportation sector. However, the expansion of this technology depends directly on the availability of an accessible and efficient charging infrastructure that meets the emerging demands of the market. In Brazil, although the number of electric vehicles has grown consistently, the charging infrastructure still faces limitations, especially regarding the availability of fast DC chargers, which are essential to enhance user experience and increase the attractiveness of electromobility in urban centers. In this context, this study aims to evaluate the technical and economic feasibility of replacing three conventional 22 kW AC chargers with a 30 kW DC fast charger at the collective charging station located at Center Shopping Uberlândia, operated by Lavita Energia. The methodology is based on a case study supported by real usage data, financial modeling of both infrastructure scenarios (AC and DC), and application of traditional economic indicators such as Payback, Net Present Value (NPV), and Internal Rate of Return (IRR). Additionally, Monte Carlo simulations were conducted to incorporate statistical variability and operational uncertainties into the analysis. The results indicate that the proposed replacement is feasible under specific operational conditions, particularly when considering the improved utilization of the station, reduced charging time, and increased user turnover potential. The analysis also highlights the importance of public policies, financial incentives, and adequate urban planning to make this type of solution economically attractive in the national context. This study contributes to the debate on charging infrastructure efficiency in Brazil and provides strategic insights for expanding electric mobility in urban commercial environments.
