Simulação de microrrede cc de veículos elétricos em plataforma HIL de baixo-custo

Abstract

Concerns with the use of non-renewable energy sources have driven research towards electric vehicles (EVs), which are more efficient and considered a green energy solution. The simulation in hardware-in-the-loop (HIL) has been increasingly used in the development of new control strategies for EVs, allowing the implementation of automated tests by simulating vehicle dynamics through discretized differential equations. This work aims to develop an electrical model of a DC microgrid of an EV and embed this model in a DSP, which should act as a low-cost HIL platform. The HIL platform should be able to simulate the switching effects of semiconductors in the microgrid and show the switching effects in the circuits. Comparisons between simulation results in the Plexim/PLECS software will be used as a reference for the tests of the HIL platform in open and closed loop. The results showed that the HIL platform can be used for the development of real control strategies, without the need for larger investments in the construction of the real vehicle microgrid.
