Gansu embracing V2G tech for EVs

In an effort to advance energy integration and improve grid flexibility, Northwest China's Gansu province is beefing up cutting-edge vehicle-to-grid (V2G) technology and enabling electric vehicles to function as "power banks" for the power grid.

Allowing energy stored in an EV battery to be replaced back into the power grid, V2G technology can facilitate the bidirectional flow of energy between vehicles and the grid, breaking the traditional limitation of EV charging patterns that solely draw power from the grid, and can now be used to support peak load adjustments while generating additional income for EV owners.

Using V2G-enabled fast-charging stations, EV owners can capitalize on time-of-use electricity pricing by charging during off-peak hours at lower rates and selling power back to the grid during peak hours at higher prices, earning profits from the price gap, said State Grid Gansu Electric Power Co, a local power operator that completed the building of its first V2G station in Gansu this month.
