China's largest vehicle-grid integration network demonstration zone has become operational in the city of Wuxi, East China's Jiangsu province. It can draw electricity to the smart grid from 50 new energy vehicles simultaneously.

According to the State Grid Jiangsu Electric Power Co Ltd, NEV owners can receive subsidies by sending unused power in their vehicles to the grid through charging piles at the demonstration center.

In the second building phase, the center is expected to add charging piles sufficient to meet the needs of charging 144 vehicles and the discharging of 50 vehicles, as well as a battery changing service for 400 vehicles at a time.

Duan Meimei, with the State Grid Jiangsu electric power marketing service center, said that the aim of the smart network is to adjust power loads for electric vehicle charging, and encourage electric vehicle owners to sell electricity in car batteries to the grid during times of high demand and to charge their batteries during off-peak hours.
