V2G Technology : Unleashing the potential of vehicle to grid integration in EV charging stations
Bidirectional EV charging technology is an impactful technology to facilitate the transition to EVs and to manage demand on the local electricity networks.These are new technologies currently,but they have the potential to help in the transition to a clean energy.V2G technology holds promise for India's EV future.This article will focus on potential of vehicle to grid integration in EV charging station
What is V2G technology and how does it work?
Vehicle-to-grid (V2G) technology allows an electric vehicle (EV) to send power into the electricity grid using a bidirectional (two-way) charger controlled via a remote management system. Some vehicles with V2G can also be used to supply backup power.
V2G technology allows an electric vehicle to synchronise with the electricity grid and inject power back into the grid using a specialised bidirectional charger. These advanced devices contain sophisticated power converters which can either charge the EVs battery or send power back to the grid when instructed, such as in times of high power demand to help stabilise the grid. To make it work following two prerequisites are required:
An electric vehicle with V2G capability.
A compatible bidirectional charger.
V2G program such as a VPP.
One can not simply connect a bidirectional charger to an EV and start feeding power into the grid without having approval from the grid operator. For it to work, the grid operator must be able to manage the bidirectional charger remotely and control the amount of energy injected into the grid. This remote management is typically done via a Virtual Power Plant program (VPP)

Grid balancing and stability- With V2G technology EV batteries can act as mobile energy storage units.During peak demand periods, EVs plugged into V2G chargers can discharge excess energy back to the grid, reducing strain and the need for additional power plants. This can be useful for integrating renewable energy sources like solar,wind etc.
Cost effectiveness-V2G can help optimize energy use and reduce overall costs. By strategically charging EVs during off-peak hours and discharging during peak hours.EV owners could also benefit from incentives for participating in V2G programs.
Smart charging infrastructure-V2G relies on bi-directional chargers and communication protocols between EVs, chargers, and the grid. This smarter infrastructure can optimize charging based on real-time grid conditions and user preferences.
Challenges to address
Vehicle to grid technology is still evolving and for its adoption huge investment is needed for bidirectional chargers and grid upgrade.
To address battery degradation concern,V2G programs need to be designed to minimize impact on EV battery life.
Standardizing communication protocols and ensuring cybersecurity for V2G systems are crucial.
India’s first V2G system- A step towards sustainable EV future
India's first V2G system is under development by Sheru, an energy software company.Their system utilizes battery swapping for a scalable and distributed approach to grid balancing.
This development signifies a growing interest in V2G to address potential grid strain caused by large-scale EV adoption.
There are potential benefits like grid management and economic advantages like electricity cost and incentives.
Summing Up
V2G technology has the potential to revolutionize the Indian power grid and help India to achieve its clean energy goals.
V2G technology is still in its early stages of development.As V2G technology becomes more widely deployed, it is expected to have a significant impact on the power grid and the way that we generate and consume electricity.
