Vehicle-to-grid technology

Definition

Vehicle-to-grid technology refers to a system that enables electric vehicles (EVs) to communicate with the power grid, allowing them to send electricity back to the grid when needed. This bidirectional flow of energy not only helps balance supply and demand but also allows EV owners to earn money or credits for providing energy back during peak usage times.
