Vehicle-to-Grid Technology in China
China's surging electric vehicles ownership, now exceeding 25.5m, is opening the door to a new technology that can help enhance the flexibility of electricity supply.
Electric vehicles (EVs) connected via "vehicle-to-grid" (V2G) technology can function as "batteries on wheels" that charge and discharge according to the needs of the wider electricity system.
The idea of turning EVs into "power banks" has already sparked both business and political interest in China.
How V2G Works
V2G involves two-way electric charging that allows EVs to act as flexible power sources, which can potentially help with the electricity supply from the grid.
- EVs with bidirectional batteries can sell their stored electricity back to the grid when plugged into V2G-capable charging stations.
- Owners can complete registration on WeChat to utilize this feature.
Author's summary: China's electric vehicles can enhance electricity supply flexibility with V2G technology.
