Abstract:
The main reason for the global climate change problem and at the same time the main source of the prosperity achieved by humanity is the use of more energy. However, most of the energy produced on a global scale is of fossil origin, and the high price, limited resources and many negative effects such as causing excessive global warming have made it necessary to increase the use of renewable energy sources. One of the main reasons for the global warming problem has been to develop and use electric vehicles, especially in the automotive sector, in order to overcome the emission of carbon dioxide gas emitted by vehicles with internal combustion engines. The biggest obstacle in the spread of electric vehicles is that the range limit depending on battery performance has not yet reached the desired levels. However, vehicle ranges that have improved as a result of scientific studies on battery technologies in recent years have rapidly increased the number of electric vehicles in the market. Correct analysis of the battery pack, which is one of the critical subsystems of electric vehicles, affects important performance criteria that directly concern the user, from driving performance to range. In this study, a battery charging system for an electric vehicle was designed and simulated using a dual-flyback converter. Theoretical analysis, modeling, fuzzy logic-based control design and evaluation of system performance of the proposed battery pack and charging circuit were carried out in Matlab/Simulink environment.
