The proliferation of electric vehicles (EVs) presents a unique opportunity to leverage batteries for grid support. Smart charging technologies allow EVs to charge during periods of low demand and lower electricity prices. Vehicle-to-grid (V2G) technology takes this concept a step further, enabling EVs to discharge energy back into the grid when needed. V2G can provide valuable grid services, such as frequency regulation and demand response, and can even help to reduce electricity costs for EV owners. However, the widespread adoption of V2G requires significant investments in infrastructure and the development of appropriate regulatory frameworks. Addressing concerns about battery degradation and ensuring fair compensation for EV owners are also critical for the success of V2G.
