Definition & In-depth Analysis: V2G (Vehicle-to-Grid) represents the cutting edge of bidirectional power transfer. It allows an electric vehicle to act as a mobile energy storage unit, capable of not only drawing power from the grid but also discharging stored energy back into the grid during peak demand periods. This technology turns EVs from simple energy consumers into active participants in the energy market.
Implementing V2G requires a synergy between the vehicle’s [BMS], a bidirectional DC charger, and the grid operator’s management system. By using V2G, EV owners can help stabilize the grid, reduce the need for fossil-fuel “peaker” plants, and even generate revenue by selling electricity back to the utility. It is a strategic technology for achieving carbon neutrality in smart cities.
Application Example: During a summer heatwave, the local power grid faces a shortage. The utility sends a signal via [MQTT] to a network of YD-EV V2G terminals. Connected vehicles that are not scheduled for immediate use automatically discharge a small portion of their battery (e.g., 5kW) into the grid. The owners are compensated with energy credits, significantly reducing their total cost of vehicle ownership.
