Vehicle-To-Vehicle Energy Transfer In Electric Vehicles Using On-Board Converters

Abstract

The main aim of this project is electric vehicle to vehicle energy transfer using on-board converters. For EV
users, existing V2V methods with an off-board power-sharing interface add extra space and expense.
Furthermore, redundant conversion stages cause V2V power transfer using on-board type-2 chargers to be
inefficient, as stated in the literature. Through the use of type-2 ac charger input ports and switches, this article
suggests a novel approach to V2V power transfer that involves directly connecting the two EV batteries in order
to share energy. A small number of switches are utilized as interfaces to link the two EV batteries instead of the
active rectifiers of on-board type-2 chargers for rectification during V2V charging. This helps to reduce
redundant power conversion and related losses, which significantly raises the overall V2V efficiency. A
simulation analysis utilizing MATLAB/Simulink is used to validate the possible V2V charging situations of the
proposed V2V strategy.
