AbstractAccording to the Brazilian Electric Vehicle Association (ABVE), between January and October 2021, 27,097 electric vehicles (EVs) were sold in Brazil. This is a sales record for this type of vehicle, an increase of 74% compared to 2020. However, the country still lacks infrastructure for charging, either due to lack of regularization or the high prices of EVs practiced in the country. Taking advantage of this scenario, the proposal of the article is to present architectures of microgrids based on hybrid sources for recharging EVs. Such arrangements rely on the integration between the electrical grid, energy storage system and renewable energy sources (RES), to recharge EVs and other loads, both in direct current (DC) and alternating current (AC), offering, in addition to environmental benefits from using RES, operational advantages such as improvements in energy quality, reliability and availability.
