| Popis: | Problem. At the present stage of science and technique development the problem of creation energy efficient vehicles is solving by electric vehicle designing: electromobiles and hybrid vehicles. Despite perspectives of a batteries electric vehicles it could be complied with a “Zero Emissions” criterions only in case if the electricity is generated from renewable sources. In addition electric vehicle may not always provide the desired range on charge. Lithium-ion batteries are now used to power the electric drive, and important problem of that is a significant weight which vehicle have to carry, it is also necessary to balance their elements, which significantly increases the charging time from the external mains. Goal. The goal of the work is to develop the theoretical basis for the creation of a system for the conversion of the "mild hybrid" vehicles in operation. Methodology. Many countries cannot afford to make the rapid transition to renewable electricity and replace the fleet with electric vehicles. Instead, a faster effect can be obtained if you re-equip vehicles that are already in use in hybrids. To successfully fulfill this goal, it is necessary to justify the parameters of the hybridization system of vehicles in order to obtain significant energy efficiency with a favorable payback period. Results. The analysis of hybrid classification and drive architecture allowed to offer new functions for "micro hybrid" and "mild hybrid" technologies. Analysis of power losses on the movement of the vehicle allowed to predict the number and power of electric motors sufficient to perform new functions. Originality. The structural scheme of the hybridization system of the motor vehicle which provides its conversion into a hybrid is developed. The study is aimed primarily at improving the technology "mild hybrid" in which electric motors of relatively low power, which are not inherent in this technology, proposed a partial implementation of the functions inherent in the technology of "full hybrid". Practical value. The combination of the features of "micro hybrid" and "full hybrid" technologies in "mild hybrid" technology should provide sufficient energy efficiency, ease of installation of system equipment and low cost. |
