Direct energy exchange between batteries causes significant current ripple, transient instability, and thermal stress on lithium-ion packs; yet, vehicle-tovehicle (V2V) power transfer is becoming a mobile charging method for grid-independent assistance.In response to these shortcomings, the authors provide a Supercapacitor-Assisted V2V Bidirectional Charging Architecture, in which a bank of supercapacitors works in tandem with the battery to provide a fastdynamic power buffer.A real-time current-sharing controller distributes transient power demand to the supercapacitor, decreasing strain on the battery during acceleration and rapid changes in load, while a bidirectional DC-DC converter facilitates regulated energy exchange.The findings from MATLAB/Simulink show that, in comparison to traditional V2V charging, the suggested method improves transient reaction speed from 4s to 7s, lowers thermal increase by about 74%, and reduces ripple current by 70-82%.Hybrid energy storage models are ideal for next-gen vehicle-to-grid (V2G) charging networks and mobile recharging systems that run on highways because they enhance charge distribution, extend battery life, and provide reliable energy transmission between moving EVs.
