GRID-CONNECTED OFF BOARD EV CHARGER WITH V2V

Abstract

The growing adoption of electric vehicles (EVs) has increased demand for efficient charging infrastructure. This project focuses on developing a Grid-Connected Off-Board Electric Vehicle Charger with Vehicle-to-Vehicle (V2V) Capability to enhance energy management and charging flexibility. The off-board charger architecture ensures high power delivery and reduces the onboard charger size in EVs, optimizing vehicle weight and cost.
The system integrates a bidirectional power converter, enabling power flow between the grid and EVs, as well as directly between two EVs. This V2V functionality allows energy transfer from a fully charged vehicle to another with low battery, providing a backup power source in emergencies or off-grid scenarios. The grid connection supports load balancing and demand-side management, contributing to grid stability.
A robust control strategy is implemented to manage power flow, ensuring synchronization with the grid and maintaining voltage stability. Safety mechanisms, such as overcurrent and overvoltage protection, are embedded to safeguard the vehicles and grid infrastructure. The proposed system enhances charging efficiency, reduces grid dependency, and paves the way for a more resilient and sustainable EV ecosystem.
