Abstract

Objectives: To produce effective technical solutions on the structure, composition and characteristics of propulsion systems of Electric Vehicles (EV) to be converted on the basis of conventional vehicles. Methods/Statistical analysis: The success of this work can be determined only in the framework of the full technological cycle for the conversion of conventional vehicles in electric vehicles. The conversion process shall be carried out according to a specialized procedure and be accompanied by a necessary implementation of specific criteria and guidelines to follow that will allow for the development of a truly effective in relation to consumer and performance properties of the electric vehicle. Findings: This article presents the results of the development of scientifically based concept for the design of the converted electric vehicles, including the methodology for calculating the key characteristics of the components of electrical traction systems, optimization criteria of operating characteristics of electric vehicles as well as the conversion principles of conversion. The aspects of the energy efficiency of propulsion systems are reviewed, while using multi-parameter characteristics, a qualitative analysis is made, including comparison of the optimal operating conditions of Internal Combustion Engines (ICE) of conventional vehicles and electric traction drive. The basic phases of conversion of vehicles to electric vehicles are laid down, which are defined in the framework of the basic phases and the necessary process operations. The results can serve as guidance material in the development of electric vehicles and assessment of electric vehicle performance at the design phase as well as contribute to a rational choice of propulsion system options at conversion. Improvements/ Applications: The indices, dependences, principles and provisions presented here build the basis of the concept of full technological cycle for the conversion and can be used to assess the characteristics of the convertible electric vehicle at the design stage, as well as contribute to a rational choice of powertrain parameters when converting.
