Design and Implementation of an Advanced Vehicle-to-Vehicle (V2V) Power Transfer Operation Using Communications

Abstract

Electric vehicles with excess energy in their battery can transfer to other vehicles during their daily trips. This paper proposes a design and implementation of an advanced vehicle-vehicle (V2V) operation, which is used to transfer energy between two electric-vehicle (EV) on-board chargers. EV owners can trade their vehicles' stored energy using this V2V operation without affecting the operation of the grid. The proposed V2V operation, which is less focused in the literature, needs to be considered in the design of each individual EV charger. An internet-of-things (IoT) platform based on the message queue telemetry transport (MQTT) protocol is also designed and implemented to govern interactions between EV owners and among EV chargers.
