Mathematical model of an electric vehicle with a non-flat battery of photovoltaic converters

Abstract

Abstract One of the major environmental problems is emissions of CO2 and other harmful substances from motor vehicles (MV). According to the tests, the most environmentally friendly MV (measurement of emissions on MVs) are electric vehicles (EV). But a low emission level can only be ensured by the use of environmentally friendly sources of electricity used to charge EV: hydroelectric power plants, wind power plants, tidal, geothermal, wave, solar power plants, etc. However, the transmission of electric energy is connected with losses. One of the ways to use them is the application of batteries of photovoltaic converters (PVC) within the EV structure as the most suitable in terms of weight and size characteristics. The use of PVC in MV is not a new idea, but due to the increase in the efficiency of PVC, their relevance becomes more obvious. Purpose of work: development of mathematical models, scientific substantiation and rationale of the calculation method of EV energy efficiency increase by enlarging the cruising range when using PVC batteries. Research methods: methods of ground MV movement theory, system design, theory of electric circuits, mathematical modeling, etc. Results: development and scientific substantiation of the calculation method for a non-flat PVC battery within the EV structure and its effect on run or mileage change. Summary: 1) the mathematical model of EV rectilinear motion on flat non-deformable horizontal ground, suitable for the study of the processes of energy exchange between the EV and PVC batteries and the effect of these processes on the mileage, has been developed; 2) the application of the calculation method for non-flat PVC batteries to be used within the EV structure has been scientifically substantiated.
