Overview - Vehicle-to-Grid (V2G)

Vehicle-to-Grid (V2G) technology operates by continuously analysing various factors
such as real-time vehicle data, electricity market conditions, and user preferences to
determine optimal charging and discharging times for electric vehicles.

Introduction

With the increasing presence of electric vehicles in the electricity system, there is a
concern about potential strain on the grid if many vehicles charge simultaneously.
However, through the implementation of smart charging and Vehicle-to-Grid (V2G)
technologies, electric vehicles have the potential to offer solutions rather than exacerbate
the issue.

This integration of the transportation sector with the electricity system is crucial for the
future, where the demand for storage and flexibility is expected to rise significantly.

V2G technology

Vehicle-to-Grid (V2G) technology operates by continuously analysing various factors such as real-time vehicle data, electricity market conditions, and user preferences to determine optimal charging and discharging times for electric vehicles (EVs). When an EV is connected for charging, the V2G system monitors grid status and adjusts the charging levels based on real-time grid conditions. During periods of surplus electricity, the EV can charge fully, while in high-demand situations where additional power is needed, the EV can discharge stored energy as required. These adjustments can occur automatically without any manual intervention from the EV drivers.

Participation in V2G programs requires customer consent, with participants receiving compensation for the energy their EV contributes back to the grid. Energy retailers or V2G service providers may calculate the exchanged energy and determine compensation based on agreed-upon rates. Compensation may come in the form of credits, reduced energy bills, or direct payments, depending on the program's structure.
