Science and Tech
A technology that enables two-way power flow between Electric Vehicles (EVs) and the power grid.
Allows EVs to store and return electricity, improving grid efficiency and energy management.
Origin
First proposed in the late 1990s by Dr. Willett Kempton and researchers at the University of Delaware.
How V2G Works
Grid to Vehicle (G2V):
EVs charge from the grid during low demand or high renewable supply periods.
Vehicle to Grid (V2G):
EVs discharge electricity back to the grid during peak demand, using bi-directional chargers.
Smart Charging System:
Utilizes Time-of-Use (ToU) pricing to:
Charge when electricity is cheap/abundant
Discharge when electricity is expensive/scarce
Significance of V2G
✅ Grid Stability
Acts as distributed energy storage, helping balance demand-supply fluctuations, especially with renewables.
✅ Supports Renewable Energy
Stores excess solar/wind power and supplies it when needed (e.g., night/cloudy conditions).
✅ Energy Resilience
EVs can power homes or buildings during natural disasters or outages.
✅ Economic Incentives
EV owners can earn money by selling surplus power—implemented in Europe & the U.S.
✅ Helps Decarbonization
Aids India’s net-zero carbon emissions goal (by 2070) by reducing fossil fuel dependency for electricity.
