Vehicle-to-grid (V2G) technology is a cutting-edge concept that allows electric vehicles (EVs) to not only receive power from the grid but also give back electricity when needed. This bi-directional flow of energy can revolutionize the way we use and manage our electricity grids, making them more efficient and sustainable. In the United States, there are several technical products designed to support V2G technology and enable EV owners to become active participants in the energy marketplace.
