Abstract. The development of the electric bus fleet, observed in the world and, in particular, in the Russian Federation, leads to the emergence of new scientific and practical problems that need to be addressed. So, at present, when electric buses are put into operation, in practice, problems arise with the choice of a rational urban regular route and the organization of charging infrastructure on it. To solve this problem, you need to know the power consumption of an electric bus, which depends on the operating conditions. This article analyzes scientific research in the field of modeling electricity consumption by an electric bus. Such an analysis and study of the experience of operating an electric bus in Tyumen made it possible to single out the factors on which electricity consumption depends. In the course of the study, a hypothesis was formulated: the factors characterizing the operating conditions on the route can be taken into account by one indicator «speed of communication». At the same time, until now, no direct influence of the ambient temperature on the power consumption of an electric bus has been revealed. Therefore, the aim of the study is to study the effect of traffic speed and ambient temperature on the electricity consumption of an electric bus on a regular urban route. To achieve this goal, a passive experiment was carried out, during which data was obtained on the functioning of electric buses, the technical parameters of the charging stations and the ambient temperature. To test the hypothesis, the initial amount of experimental information was processed using statistical data processing methods. It was found that a decrease in the speed of communication causes an increase in the consumption of electricity by an electric bus. During the analysis of the influence of the ambient air temperature on the considered output parameter, it was revealed that when it deviates from the value equal to + 4 °C, an increase in the consumption of electricity by the electric bus is observed. As a result, the established regularities of the influence of the speed of communication and the ambient air temperature on the electricity consumption of an electric bus and their mathematical models will become the basis for further research for the development of a methodology for rationing electricity consumption by an electric bus on a regular city route.
Key words: electric bus, energy consumption by electric bus, shipping speed, ambient temperature, parameters of route.
