Definition of V2G

Vehicle-to-Grid (V2G) technology refers to the connection and bi-directional flow of power between electric vehicles (EVs) and the electrical grid. It enables EVs to not only consume electricity from the grid but also feed electricity back into the grid, turning them into mobile energy resources.

How V2G works

V2G technology enables EV owners to not only charge their vehicles but also discharge energy stored in their batteries back into the grid when needed. By utilizing bidirectional charging technology, energy can flow both ways between the EV and the grid, allowing the grid to draw power from the EV’s battery during peak demand and supply power back to the EV during times of low demand.

Benefits of V2G

V2G technology provides numerous benefits to both EV owners and the overall energy system. For EV owners, it creates opportunities to not only reduce the costs associated with charging their vehicles but also generate revenue by utilizing their EVs as energy assets. Additionally, V2G technology enhances the overall stability and reliability of the electrical grid by balancing energy supply and demand, reducing the need for expensive grid infrastructure upgrades, and facilitating the integration of renewable energy sources.
