“…Одне з можливих та найбільш цікавих і ефективних рішень -це встановлення на автокемпер малопотужної сонячної електростанції на базі фотоелектричних модулів. Таке рішення дає можливість зупинятися у будь-якому місці, яке вам сподобалось, звісно, якщо це не обмежено законодавчими нормами та природними умовами, і, водночас, користуватися всіма наявними технологіями, що отримають живлення від електроенергії [2][3][4].…”

Problem. An RV combines two essential features desired by modern travelers: the ability to relax in unconventional locations while still being able to work remotely if your job requires remote access. However, if you're accustomed to the conveniences that rely on electrical power, you'll find yourself searching for places to connect to the centralized power grid. Alternatively, you'll need to seek solutions to this issue. One of the most intriguing and effective solutions is the installation of a low-power solar power station on the RV, based on photovoltaic modules. This solution enables you to park and enjoy any location you prefer while benefiting from all the available technologies powered by electricity. Goal. This study aims to investigate the installation of an autonomous solar power station on an RV and determine its electrical power generation capacity. Methodology. Analytical research methods were employed to explore the development and application of solar energy conversion methods and devices to generate electricity. Experimental research methods and mathematical techniques for processing experimental data were also utilized. Results. The RV type suitable for installing an autonomous solar power station has been identified, specifically the Roller Team Sirio 599. An investigation of its equipment in terms of electricity consumption has been conducted. Furthermore, a self-sustaining solar station has been proposed for the selected RV, and the electricity generation schedule of this station has been studied. The electricity consumption by RV appliances has been thoroughly examined. Originality. This study explored the volt-ampere characteristics of photovoltaic modules and their power generation dependency on the load. The investigated photovoltaic modules demonstrate maximum operational efficiency in the active load range from 3 ohms to 3.5 ohms. Practical Value. The research findings indicate that starting from March, the solar power station on the RV is fully capable of meeting its electricity consumption needs. In the winter months, particularly in November, in Ukraine's climate conditions, this solar power station may only cover a portion of electricity consumption needs. Considering that electrical devices are often used for heating the RV, this solar power station should not be relied upon as the primary source of electrical power.

Problem. Despite the widespread use of asynchronous electric motors (ED) in electric transportation, they often fail to meet high reliability requirements. This is primarily due to their operation in a wide range of rotational frequencies, variable load modes, frequent stops and starts, and challenging road conditions. These factors result in significant vibrations of traction asynchronous EDs, leading to reduced reliability and service life. Goal: The goal of this study is to develop methods to enhance the reliability and longevity of traction asynchronous EDs by improving the design and manufacturing technology of the stator housing and rotor of the electric motor. Methodology: Analytical research methods were employed to investigate approaches for improving the quality of traction electric motors for electric transport. Experimental research methods were used to determine the technical condition of EDs based on their vibrodiagnostic parameters. Statistical methods were utilized to process experimental data. Results: Vibration levels, which are indicative of the technical condition of EDs, were selected as the primary criterion for assessing their quality. The proposed design and manufacturing technology for asynchronous electric motors enable the following: increased manufacturing and assembly precision of EDs, simplified assembly process, reduced number of sorted parts during inspection and bearing replacement, and the development of an asynchronous traction ED with a power capacity of 90 kW and a rotational frequency of 3000 rpm, meeting class D requirements with permissible vibration levels. Originality: This study presents developed methods for increasing the reliability and longevity of traction asynchronous EDs through experimental approaches. The one-sided arrangement of base surfaces in the stator housing and the attachment of rotor bearing units enabled the production of a vertical ED assembly consisting of two independently controlled units: a housing with a shield and a rotor with bearing units. Practical Value: The achieved reduction in vibration levels allows for a predicted 2-3 times increase in the lifespan of the developed ED, depending on operating conditions. Furthermore, the created ED meets all environmental standards' requirements for vibration levels.

Problem. Improving automobile transport means increasing fuel economy and environmental indicators. Fuel, in a broad sense, means energy used to activate the car's power plant. Potential energy is dispersed in the earth’s interior, on its surface, in the atmospheric air, and even in space. Moreover, some of them exist in different substances. On the one hand, the efficiency of an energy product use is assessed by its energy intensity; on the other hand, it is evaluated by the costs of its production (transportation) and the quality of its transformation into a consumer type of energy. Special attention is paid to renewable and unlimited kinds of energy sources. Goal. The purpose of the study is a qualitative analysis of the road transport development direction from the standpoint of the alternative energy sources use, taking into account the factors that comprehensively determine the economic and environmental indicators at the stages of production and processing of fossil raw materials, production of power plants and conversion, transformation, and transportation of energy in the field of transport technologies. Methodology. The first direction consists of the adaptation (conversion) of the design of thermal internal combustion engines for alternative liquid or gaseous fuel types. The advantage of this approach is minimal costs for engine conversion and fuel production. The second approach involves using hybrid power plants, consisting of a main and auxiliary engine, an energy source or accumulator, an energy converter, and a braking recuperation system. The third direction is the use of non-traditional energy sources. Results. The directions of the development of power plants for motor vehicles related to the increase in the energy density of hydrocarbon fuels, the use of hybrid power plants, and the use of alternative energy sources have been determined. A qualitative assessment of the considered approaches is given. Originality. A comprehensive approach to evaluating the effectiveness of using alternative types of energy in road transport is considered in terms of energy, economic, and environmental indicators. Practical value. The obtained results can be regarded as recommendations when drawing up plans for the evolution of industries of fossil extraction and transformation of other energy resources, the development of motor vehicles, and transport infrastructure technologies, taking into account the natural and industrial potential of the country
