Modern electric automobiles tend to have greater battery capacities. Battery packs with an average capacity of 16-22 kWh were used at the initial stage of manufacturing serial electric vehicles. A number of new models of electric vehicles are equipped with batteries, the capacity of which exceeds 30 kWh, which can result in a significant increase in the basic weight of the electric vehicle. Any increase in the weight can lead to an increase in energy consumption per km travelled. The present research developed a methodology for determining the range and dynamic parameters of electric vehicles depending on changes in the basic weight of the vehicles. The present research also calculated the effect of changes in the weight for various serial electric automobiles.
