DETERMINATION OF ELECTRICITY CONSUMPTION DURING OPERATION OF ELECTRIC VEHICLES IN COUNTRY MODE
The article is devoted to the problems of operation of cars with an electric power plant in the conditions of specific climatic and road conditions of Russia. The analysis of the electric vehicle market is carried out. It has been established that Russia is significantly lagging behind the global trends of switching to alternative energy sources for road transport. However, there is a pronounced tendency to increase the rolling stock of electric vehicles. In winter operation, owners of electric vehicles face incorrect calculation of the power reserve, and with significant long-distance runs, this can lead to premature use of the power reserve and the impossibility of further operation of the vehicle. The article presents the results of studies of the electric power consumption of a 2014 Tesla Model S car with an electric motor with a capacity of 285 kW and a high-voltage battery capacity of 85 kWh when driving in country mode. It has been established that the declared indicators of the electric vehicle's power reserve during operation in the Perm Region significantly decrease, even when driving in economy mode and at a positive ambient temperature. When operating commercial vehicles, there is a problem of writing off electric energy to charge the high-voltage battery of the rolling stock fleet. The existing norms do not allow to correctly and reliably determining the power consumption during operation in changing climatic and road conditions, and amendments to the basic fuel consumption rate are given for cars with internal combustion engines. Thus, it is necessary to establish a quantitative dependence of the change in electricity consumption on external factors during the operation of an electric vehicle.
