Abstract. Introduction. This study analyzes the theoretical and practical aspects of using renewable energy sources, particularly solar energy, for charging electric vehicles. The research is aimed at developing a sustainable charging infrastructure based on modern technologies and is implemented through the modeling of a hybrid energy system.
Methods and Materials. This study examined the use of solar energy for charging electric vehicles. A mathematical model of a hybrid energy system, consisting of solar panels, a battery management system, and the electrical grid, was developed and simulated using MATLAB and PVsyst software. Energy production based on solar irradiance and demand analysis was conducted. The model helps optimize real-time energy flow and reduces carbon dioxide emissions.
Results. The research results show that hybrid systems based on solar energy significantly reduce energy consumption during electric vehicle charging. According to simulations, most of the generated energy is used directly for charging, while the surplus is stored in batteries or fed into the grid. This approach improves overall energy efficiency and helps reduce carbon emissions. The system’s economic and environmental advantages have been confirmed.
Conclusion. The new technological solutions being developed for electric vehicle charging play an important role in improving energy efficiency and protecting the environment. This study developed a hybrid system integrating standalone solar energy sources with grid power. The proposed system reduces dependence on the grid and ensures stable and environmentally friendly charging operations.

Результаты. Результаты исследования показали, что гибридные системы на основе солнечной энергии значительно снижают энергопотребление при зарядке электромобилей. Согласно результатам моделирования, основная часть вырабатываемой энергии используется непосредственно для зарядки, а избыточная энергия накапливается в аккумуляторах или передаётся в сеть. Такой подход повышает общую энергетическую эффективность и способствует снижению выбросов углерода. Экономические и экологические преимущества системы подтверждены.
