Revisão das tecnologias no powertrain de veículos elétricos e híbridos

Abstract

Electric vehicles (EVs) appear as humanity’s next great step towards sustainable development as renewable energy sources gain more space in the world’s energy supply. With this fact in mind, alongside Brazil’s need to invest in many fields to expand its power in the automotive industry, which is in a moment of great opportunities ahead, this paper aims to review the earlier technologies, the state of the art and the trends around an EV’s powertrain components, aiming to build a foundation that can guide future Brazilian researchers in their studies. Beyond the powertrain, this paper discusses about other relevant factors to the world’s EV market, such as China’s expansion and their contributions to the vehicles. With the information gathered to write this paper, it was concluded that the electric motors reached a comercially satisfactory level of development, and the future models will aim towards better power density, especially with the recent rise of the permanent magnet motors. Also, it was showed that Brazil has great potential to develop EVs in the future, and that many factors should be equally invested into so that the energetic transition can happen smoothly.
