China’s Large Vehicle-to-Grid Experiment: 1,277 Electric Cars Return Energy to the Grid

Discount coupons in exchange for participation in a mass experiment. That’s what they’ll get 1,277 Electric Car Owners in Chinawhere a project was started to evaluate the feasibility and weight of the vehicle-to-grid.

Sometimes abbreviated to V2Gprovides for electric cars to be connected to bidirectional charging pointscapable of drawing energy from car batteries, and redirect it to the network if necessary. Cars charge at times when peak demand is low, and generally deliver power when demand increases significantly.

The project is operated by State Grid Operator Jiangsu Electric Power, and involves 482 charging stations. A forecast of the manager estimates that by 2030, electric cars in Jiangsu will exceed 10 million. A spokesperson said: “If just 10 percent of these vehicles participated in reverse discharge, they could provide over 1 million kW of peak cutting capacity, equivalent to connecting a 1 million kW portable power bank to the grid.“.

The same state-owned company is conducting another test using electric busesalthough in significantly lower numbers, only two vehicles. The advantage of buses is that they have a very large battery, and are able to handle higher power than cars. Furthermore, the bus stop is programmed with extreme precision compared to private vehicles.
