Vehicle-to-vehicle wireless charging with decoupled primary side control

This paper explores wireless vehicle-to-vehicle (V2V) charging as a solution to electric vehicle charging challenges. The focus is on designing a wireless power transfer system for V2V charging, emphasizing resonant networks for high-efficiency power transfer. The LCC–LCC resonant network is employed due to its advantages over other topologies. The paper also introduces a robust primary side control system based on capacitor voltage control to regulate output power, addressing the impact of coupling variation resulting from the dynamic movement of charging vehicles. The proposed system, validated through a 6.6-kW simulation model, achieves an average closed-loop DC-to-DC efficiency of 94.1%, demonstrating stable output power under coupling variations. Finally, a list of future works identified from this paper, which deserve further studies.
