Viabilidade econômica de um sistema de recarga de veículos elétricos em um posto de combustíveis na cidade de Santa Maria

Abstract

In the current world scenario, the adhesion to electric vehicles has been growing more and more, including in Brazil. In order to further foster this growth, it's essential that countries make investments in infrastructure, such as installing charging stations. Given this scenario, the objective of this research is to analyze the economic feasibility of an electric vehicle charging system at a fuel station in the city of Santa Maria. To develop the study, information was collected from 9 level III fast charging stations. 54 scenarios were modeled, comprising the selected recharge models, the electricity tariff flags and the operating hours of the equipment. The Economic Engineering methods used were the Net Present Value (NPV), Internal Rate of Return (IRR), Discounted Payback, combined with the Annual Equivalent Cost (CAUE) and the R$/kWh consumed value of each model. The results obtained were a maximum negative NPV of R$ -2.896.317,54, making its investment unfeasible. The most viable model was the WEG wemob Parking, with a NPV of R$ R$ 79.688,14, presenting an IRR of 23,58% and a Payback of 4,47 years.
