Carregador de baterias off-board para carros elétricos a partir de redes monofásicas

Abstract

This work aims to build a charger for electric vehicles from single-phase energy grid, developing a study on electric vehicles and hybrid vehicles. The aim was to describe the stages of conversion of chargers as well as the evolution of the charging system. In the literature review, the topologies of existing batteries with the possibility of being used in electric cars were analyzed, as well as the topologies of converters that can be part of the charger. Finally, with the studies done, one of the battery topologies was used to serve as a charger charge. The PFC and CC CC converters were also used, which proved to be the most suitable for the charger project. The validation of the topologies and the evaluation of the charger output was done through simulation and experimental implementation. After simulation, a practical implementation of a battery charger was carried out and, finally, the charger was submitted to the necessary tests for its proof of operation.
