Vehicle-to-Grid (V2G) is an advanced EV technology that enables electric vehicles to send stored energy from their batteries back to the electricity grid. Instead of only consuming power, EVs can act as mobile energy storage units that support the grid when needed.

With V2G, energy flow becomes bidirectional. When the grid is under stress or demand is high, EVs can discharge a portion of their stored energy back to the grid. During low-demand periods, they can recharge as usual. This helps balance supply and demand more efficiently.

V2G plays an important role in improving grid stability, especially as renewable energy sources like solar and wind become more common. Since these sources are variable, EVs can help store excess energy and supply it back when production drops.

For EV owners, V2G can create opportunities to earn incentives or reduce electricity costs by selling energy back to the grid during peak pricing periods. For utilities, it provides a distributed energy resource that reduces the need for additional infrastructure.

However, V2G requires compatible vehicles, bidirectional chargers, and supportive regulations to function effectively. While still emerging, it is considered a key technology for building a more flexible and resilient energy system.

Overall, V2G transforms EVs from simple energy consumers into active participants in the energy ecosystem, supporting smarter and more sustainable power management.
