Efficiency of photoelectric converters intellectual system application on ground electric transport

Abstract

The development of environmentally friendly road transport is now directly related to the introduction of electric actuators, high-voltage storage systems and the accumulation of electricity in transport. Thus, a significant variety of hybrid traction drive circuits appears, which can be charged from an external power source. However, all of them use hydrocarbon fuel for charging and storage of electricity, which emits CO2 while burning. Clean electric vehicles are the most efficient in terms of environmental indicators, since they use only electricity produced in power plants located far from the operation aureole of the electric vehicle, which allows to improve the environmental situation in megapolises significantly. As you know, energy complexes in different countries have different environmental efficiency and CO2 emissions during power generation are also present. Transition to the use of renewable energy sources, such as solar power plants, can give its effect, since at present, their productivity in the world reaches 400 GW, but the transmission of energy over distances reduces the efficiency. Thus, based on the development trends of solar power plants, it is important to consider the use of photovoltaic cells, the so-called “solar cells” directly on the electric vehicle itself in order to improve environmental friendliness.

Implementation of Dual-Circuit System for Additional Power Supply Based on Photovoltaic Converters for Electric Vehicles

“…The results of mathematical modeling showed that in different latitudes of the Russian Federation the photovoltaic converters system may provide up to 260 kWh per year of electricity in the northern part of the country (at the latitude of St. Petersburg), up to 280 kWh per year in the central part of the country (at the latitude of Moscow), and up to 380 kWh in the southern part of the country (at the latitude of Sochi and Astrakhan). Taking into account CO2 emissions from electricity generation in the Russian Federation, it can be said that the use of this system in an electric vehicle will help to avoid unnecessary CO2 emissions in the amount of 153,000 to 240,000 grams per year [8] compared with an electric vehicle of a similar class with a standard method of charging [9].

“…The WLTC cycle is generally less dynamic than ARTEMIS (mileage increased to 3.8%), but in the city cycle, it is not as favorable for the use of solar cells (up to 9.8%). In the second stage of work, according to the developed methodology, PHV elements with the most similar characteristics for battery manufacture were tested and selected [9]. The control units for operation of the temperature control system and the additional power supply system based on In the second stage of work, according to the developed methodology, PHV elements with the most similar characteristics for battery manufacture were tested and selected [9].…”
