On-Board Converters for Electric Vehicle-to-Vehicle Energy Transfer

A modern method of energy sharing among electric cars (EVs) is electric vehicle-to-vehicle (V2V) charging. For EV users, current V2V methods with an off-board power-sharing interface incur extra space and expense. Moreover, redundant conversion steps make the on-board type-2 chargers used for Vechile2Vechile energy transfer described in the literature inefficient. Automatically connected the two electric vehicle batteries to share energy via switches and type-2 ac charger input ports, this paper suggests a novel approach to V2V power transmission. In order to prevent redundant power conversion and related losses, the active rectifiers of on-board type-2 chargers are not utilized for rectification during V2V charging; rather, a small number of switches serve as interfaces to link the two EV batteries together, so improving the total efficiency of V2V. Through MATLAB/Simulink simulation research, the potential V2V charging scenarios of the suggested V2V technique are verified. Additionally, a scaled experimental prototype is created in order to actually evaluate the suggested V2V approach.
