Abstract

THE PURPOSE. The lack of charging infrastructure is one of the main reasons for the refusal to use electric vehicles in Russia. The solution could be the development of mobile electric vehicle charge units (MCSEU). To implement a truly competitive product, it is necessary to take into account all possible types of electric vehicle charging, and not only standard ones, CHAdeMO, CCS, etc., but also wireless charging based on an induction charger (IC). Therefore, the purpose of this work is to model the two main types of IC implementation, compare the results obtained, and develop a physical modeling model for the selected scheme.MATERIALS. IC is based on the principle of magnetic induction, so the simulation was carried out for two options for implementing contactless charging, the frequency and value of the inductances of the coupled coils were calculated, and based on the results obtained, conclusions were drawn about the optimal distance at which the required efficiency value is maintained. For physical modeling of the process of non-contact charging of electric vehicles, a calibrator model has been developed, and ferrite plates have been calculated.RESULTS. Based on the simulation, a scheme for the implementation of the IC with adjustable capacitor capacitance was chosen, the topologies of antennas and the geometry of ferrite plates and a design documentation of a 6-axis calibrator for testing were developed. R&D was carried out at the Federal State Budgetary Educational Institution of Higher Education "KSPEU".CONCLUSION. The use of IC provides great opportunities for the development of mobile charging stations, as it increases the number of possible connections. However, efficiency and charging distance are critical for this equipment, therefore, already at the modeling stage, it is necessary to select the parameters of the coils as accurately as possible, and the circuit used. For the developed MCSEU, within the framework of Resolution 218, optimal solutions were identified in the field of modeling and testing of IC.
