Vehicle-to-Grid (V2G) Technology

Vehicle-to-Grid (V2G) Technology Latest News

Recently, the Kerala State Electricity Board (KSEB), in partnership with IIT Bombay, has launched a pilot V2G project to test its feasibility in the state.

What is Vehicle-to-Grid (V2G) Technology?

• Vehicle-to-Grid (V2G) is a set of technologies that enable Electric Vehicles (EVs) to send stored electricity back to the power grid when they are not in use.
• When an EV is idle and connected via a bi-directional charger, it can act as a decentralised battery energy storage system, contributing electricity to the grid.
• V2G supports both charging (Grid to Vehicle – G2V) and discharging (Vehicle to Grid – V2G) of EV batteries, creating a two-way energy flow.
• EV batteries act as a load on the grid during charging, which can be managed using tools like Time of Use (ToU) tariffs and smart charging to reduce stress during peak hours.
• During discharging, EV batteries serve as distributed energy sources, providing electricity during peak demand periods or when renewable energy (RE) is low.
• V2G is part of a broader framework including Vehicle to Home (V2H) and Vehicle to Vehicle (V2V) applications, but V2G is the most widely explored use case globally.

Vehicle-to-Grid (V2G) Technology FAQs

Q1. What is V2G Technology?
Ans. Vehicle-to-Grid (V2G) Technology allows electric vehicles (EVs) to return stored electricity back to the grid when they are not in use, helping balance energy supply and demand.

Q2. How does V2G Technology benefit the power grid?
Ans. V2G helps stabilize the power grid by storing surplus energy in EVs during low demand and supplying it back during peak demand periods, thereby reducing the load on power stations.

Q3. Why is V2G important for renewable energy integration?
Ans. V2G enables efficient energy storage, helping overcome the intermittent nature of renewable energy sources like solar and wind by using EV batteries as distributed energy reservoirs.
