Introduction to Vehicle-to-Grid (V2G) Technology

  • Kerala, in partnership with IIT Bombay, has initiated a pilot project testing the potential of Vehicle-to-Grid (V2G) technology.
  • V2G technology allows the unused power stored in Electric Vehicle (EV) batteries to be returned back to the power grid. 
  •  Not only does this enable better integration of renewable energy sources, but it also bolsters the stability of the power grid. 

 

Operational Modes of V2G Technology

  • V2G technology operates in two key modes. 
  • Grid-to-Vehicle (G2V) is the mode where EVs are charged using power from the grid.
  • In the Vehicle-to-Grid (V2G) mode, the stored power in EVs is discharged back to the grid.

 

Importance and Role of V2G Technology

  • V2G technology allows EV users to provide services during the irregular output of renewable energy sources, acting as a decentralized storage resource. 
  • This is particularly beneficial during times of emergency when power is needed. 
  • Global and Indian Scenario of V2G Adoption 
  • Countries like the U.S., U.K, and the Netherlands are leading in adopting V2G technologies. They have adopted a compensatory model where EV owners are paid for supplying power during periods of peak demand. 
  • In comparison, India is still in the nascent stage of V2G adoption. The primary focus currently is on expanding and improving the EV charging infrastructure. 

 

However, India is making an effort to fully leverage the benefits of V2G technology. The Central Electricity Authority (CEA) has set up a committee to explore reverse charging possibilities, under its chairman's leadership.
