Vehicle-to-Grid (V2G) Technology:
The Kerala State Electricity Board (KSEB), in partnership with IIT Bombay, has launched a pilot V2G project to test its feasibility in the state.
- 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.
- During charging, EV batteries act as a load on the grid, 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
