In the final paper, it is explained from the discovery of electric cars to the present day and their technological development. The types of these vehicles, their maintenance and the differences and advantages over conventional vehicles with an internal combustion engine are listed. Electric cars are advancing very fast technologically but are still not competitive with diesel and gasoline engines, due to the fact that battery life in electric cars cannot replace internal combustion engines. Underdeveloped batteries and poor infrastructure entail that it is a wiser choice to choose a car with an internal combustion engine. All cars, including electric ones, require maintenance. With electric cars, maintenance is significantly cheaper compared to conventional ones, which brings greater economy and greater environmental awareness. Due to the introduction of new eco-standards that are taking more and more breath, especially in the countries of the European Union, electric generators are becoming more and more popular and will eventually completely replace diesel and gasoline generators.
