TLDR: In this paper, the authors presented an optimized V2V charging system with improved parameters, achieving an overall efficiency of 60% in hardware at a coupling coefficient of 0.02 for the proposed system.

Abstract: Electrification of vehicles becoming a widely discussed term among the enthusiastic researchers in the present century. They have contributed a plethora of techniques to this cause. As more research conducted in the field of electric vehicle charging, sustainable transportation gained more importance. Renewable energy powered electric vehicles are introduced by the same cause. Parking slots are then transformed into a large source of solar energy by the integration of solar panels. For the ease and flexibility of charging, wireless charging techniques are introduced. Vehicle-to-vehicle (V2V) wireless charging technique is introduced to meet the contingency conditions like battery drain during a long ride. Present V2V technology has disadvantages like poor transfer efficiency, coupling separation, and misalignment tolerance. This chapter presents an optimized V2V charging system with improved parameters. An overall efficiency of 60% is achieved in hardware at a coupling coefficient of 0.02 for the proposed system. For conventional WPT model, the overall efficiency 60% is for coupling coefficient of 0.09 only. Results are verified with PSIM simulations and hardware.
