Abstract The tremendous growth in the transportation sector as a result of changes in our ways of transport and a rise in the level of prosperity was reflected directly by the intensification of energy needs. Thus, electric vehicles (EV) have been produced to minimise the energy consumption of conventional vehicles. Although the EV motor is more efficient than the internal combustion engine, the well to wheel (WTW) efficiency should be investigated in terms of determining the overall energy efficiency. In simple words, this study will try to answer the basic question – is the electric car really energy efficient compared with ICE-powered vehicles? This study investigates the WTW efficiency of conventional internal combustion engine vehicles ICEVs (gasoline, diesel), compressed natural gas vehicles (CNGV) and EVs. The results show that power plant efficiency has a significant consequence on WTW efficiency. The total WTW efficiency of gasoline ICEV ranges between 11–27 %, diesel ICEV ranges from 25 % to 37 % and CNGV ranges from 12 % to 22 %. The EV fed by a natural gas power plant shows the highest WTW efficiency which ranges from 13 % to 31 %. While the EV supplied by coal-fired and diesel power plants have approximately the same WTW efficiency ranging between 13 % to 27 % and 12 % to 25 %, respectively. If renewable energy is used, the losses will drop significantly and the overall efficiency for electric cars will be around 40–70% depending on the source and the location of the renewable energy systems.

History Of

The work is devoted to the urgent issue of the invention and development of foreign and domestic electric vehicles, which is one of the possible directions in solving the issue of environmental conservation. Almost 80% of the global automotive market is heading for a ban on gasoline and the switch to electric cars and hybrids. However, this movement was, until recently, leisurely, if not slow. The popularity of electric vehicles in the world is due to the fact that they have several advantages compared to cars with an internal combustion engine. The principle of operation of an electric vehicle is based on the fact that the movement is provided by the operation of an engine that uses electric energy for its work. The electric motor plays the same role as the internal combustion engine, in addition, in the electric car, it is possible to install several engines that are able to distribute energy more efficiently and more rationally. Batteries play the function of a fuel tank, which supplies the engine with the energy necessary to ensure the movement of the car. For Ukraine, innovation is very important for the development of our country. Constant demand makes it clear that the future of electric cars. Ukrainians are paying more and more attention to such passenger cars, or hybrid ones. Every year the number of registered electric vehicles becomes more and more. The article highlights the main stages of the development of electric vehicles and presents the main problems of these vehicles, which indicate that they tend to be constantly improved.

Annotation – The analysis of scientific publications over the past ten years in the direction of creating gas ICEs in Ukraine, operating on natural gas, biogas or similar low-calorie fuels. The objectives of the work summarize the results of studies on the use of model gas in a gas internal combustion engine operating on a power plant drive. Developed recommendations on biogas additives to natural gas depending on the power plant load, and to develop a fuel control algorithm. The article provides recommendations on setting up the power system and automatic regulation of a gas engine running on a mixture of natural gas (methane) and biogas. To solve the tasks, a gas-electric installation with a rated power of 30 kW was tested. Initially, the installation was equipped with an 8-cylinder gasoline engine with spark ignition and an electric generator. The base ICE was converted to purely gas with a compression ratio of 8.5. In the physical modeling of biogas to natural gas additives in the model gas, the volume fraction of carbon dioxide increased to 30 % with a decrease in the load. By calculation, determined a similar ratio of compressed natural gas and biogas additives. For the calculation, it assumed that natural gas contains 90 ... 95 % methane, and biogas 60 % methane and 40 % carbon dioxide. The possibility of using biogas with 60 % methane as an additive to natural gas in piston ICEs with spark ignition has been confirmed. It was found that with a decrease in load, the biogas fraction increase and replace up to 85 % of natural gas. When working on biogas additives, the values of the concentrations of hydrocarbons and residual oxygen in the exhaust gases were determined to control the setting of the gas equipment of the internal combustion engine. Under operating conditions, three test modes selected for the power plant: idle, 50 % load, rated mode. The research results can serve as the basis for creating a control algorithm for the supply of biogas additives to natural gas, depending on load changes.
