Design analysis of matrix converter for wireless Vehicle-to-Vehicle charging system and ecological footprint assessment of electric vehicle charging station

Abstract Electric vehicles (EVs) are increasingly being adopted as a sustainable transportation due to their lower dependency on fossil fuels and low emissions. However, charging time and range anxiety issues in battery technology are affecting the development and growth of EVs. The proposed study examined the system performance of wireless power transmission between two vehicles using a single-phase phase charging matrix converter system. Thus, besides its capability to convert the voltage level, the proposed matrix converter is designed to be an active power filter that helps enhance the power factor and the quality of the wave shape of the input current. A transmitter and receiver shape of coil is also recommended for a wireless Vehicle-to-Vehicle (V2V) charging system with consideration of misalignment and geometrical matching between the transmitters coils are mounted on the front side while the receiver coils are fixed on the rear side. The currently proposed core elements were seen to be effective in transferring power by super-thick silicon steel laminated core (current drawn up to 1.64 A) and a super-thick ferrite core (current drawn up to 1.89 A), both have very less hysteresis loss, which improves system performance. The ecological footprint (EF) associated with electric vehicle (EV) battery charging is estimated to be approximately 3.1 × 10 −4 gha/kWh. New research shows V2V wireless electrical vehicle charging can play a critical role in lowering greenhouse gas emissions combined with other air pollutants compared to traditional battery charging systems. The proposed methodology contains comprehensive modelling of the switching behaviour of the matrix converter as well as control strategies and equations of power flow. The experimental validation is conducted with alternative core materials, and the analysis of the efficiency of the proposed wireless V2V charging system is made with the results that justify the possibility and functionality of the proposed system.
