Abstract:

One of the parameters of electric vehicles that can affect their dynamic and range characteristics is their weight. Converting a vehicle with an internal combustion engine into an electric one, it is possible to vary its batteries and their placement. It is also possible to choose batteries of various capacities for serial electric vehicles, for example, Tesla Model S. Not only the costs of electric vehicles but also such performance characteristics as dynamics and travel range per charge depend on the number of batteries and the total weight of the electric vehicles. The research developed and approbated an algorithm for calculating comparative parameters for electric automobiles. The algorithm was approbated on 30 electric automobiles of various makes. Energy consumption per km distance travelled shows the exploitation cost of an electric automobile. According to this indicator, the most economical electric automobiles were as follows: Renault Twizy (67.8 Wh km-1), Tazzari Zero (87.9 Wh km-1) un Renault Zoe ZE22 (93.6 Wh km-1).
