Mathematical Modelling of Cogeneration Photoelectric Module Parameters for Hybrid Solar Charging Power Stations of Electric Vehicles

The paper studies the possibility of creating local power grids for charging rechargeable batteries of electric vehicles from solar power plants based on cogeneration photovoltaic modules installed on the roofs of administrative buildings of filling stations in order to save energy obtained in a conventional way. It is suggested to use a solar power plant with cylindrical cogeneration photovoltaic modules cooled with liquid. This will enable creating hybrid solar power plants for simultaneous production of electricity and heat. A mathematical model of the surface area of a cylindrical photovoltaic converter as a function of battery parameters has been obtained. To calculate the efficiency of a hybrid photovoltaic converter, the dependency of the temperature coefficient of a cylindrical photovoltaic converter on its temperature has been derived. The results of the research are recommended for use while designing and calculating hybrid solar power plants for charging electric vehicles batteries.
