en.Wedoany.com Reported - On April 28, the Yanglin Road Integrated Charging, Swapping, and Discharging Demonstration Station, operated by State Grid Hefei Power Supply Company, was officially inaugurated in Shushan District, Hefei City. Positioned as China's first vehicle-to-grid (V2G) interaction demonstration station encompassing operation, verification, and incubation, it deeply integrates cutting-edge technologies such as quantum communication and quantum measurement, comprehensively upgrading charging and swapping service capabilities and energy interaction levels. According to Anhui Business Daily and Science and Technology Daily, the station simultaneously features the world's first batch of BYD megawatt flash charging stations, which can add 200 kilometers of driving range to mainstream models in just five minutes.
The scale and core service data for the station have been preliminarily set. As disclosed by Hefei Online and the Kechuang Rong Channel, the demonstration station houses two battery swap stations from NIO and CATL. The average swap time is only 3 minutes, with a daily service capacity exceeding 1,000 swaps, placing its scale among the top in Anhui Province. Notably, the NIO swap station features a grid-to-vehicle reverse discharge function, enabling flexible participation in grid peak shaving. The station is equipped with 72 charging guns, 53 of which feature V2G reverse discharge capability, enabling bidirectional energy interaction between vehicles and the grid. Furthermore, according to Anhui Business Daily, the concurrently built BYD megawatt flash charging station has per-pile power exceeding 1,000 kilowatts, adding 200 kilometers of driving range to vehicles in 5 minutes.
In terms of green energy utilization, the demonstration station features a 197 kilowatt rooftop and carport photovoltaic power station and a 1-kilowatt wind turbine. According to precise data provided by Hefei Online, the annual power generation is approximately 220,300 kilowatt-hours, saving about 67 tonnes of standard coal and reducing carbon dioxide emissions by approximately 220 tonnes annually. The green electricity supplies the station with priority use, with any surplus stored in a 500-kilowatt/1-megawatt-hour new energy storage station. During peak grid load periods, this stored energy is discharged for peak shaving, thus enhancing the efficiency of local renewable energy integration and consumption.
The deep-seated application of quantum technology across multiple scenarios constitutes the station's most central technological breakthrough. Leveraging a quantum-secured communication scenario, the project connects the station to the Hefei Virtual Power Plant platform. Using "5G + Quantum Encryption" technology, it relies on the inherent physical properties of quantum unmeasurability and non-clonability to establish an absolutely secure transmission channel for dispatch and control commands. This achieves millisecond-level responses for all interacting vehicles, efficiently completes reverse discharging to the grid, and provides real-time monitoring data on equipment operation, vehicle status, and energy interaction. As reported by a Science and Technology Daily reporter, faced with the challenge of insufficient metering precision for ultra-high-power charging, the station has piloted the installation of quantum precision measurement devices on multiple charging piles. This has successfully overcome the metering accuracy bottleneck and provides a technical guarantee for market-based settlement of V2G interactions.
In terms of operational mechanisms, the Hefei Vehicle-to-Grid Interaction Operation Center and Technology Verification Center were established on the station site. The Operation Center offers real-time online monitoring for up to 16 V2G demonstration projects and 170 V2G bidirectional charging and discharging piles across the city; the Technology Verification Center is deployed with six sets of professional monitoring equipment, capable of specialized monitoring tasks including V2G charging pile grid-connection performance and power quality evaluation. Targeted at new energy vehicle enterprises and charging facility companies on a nationwide basis, the demonstration station also freely opens its experimental field scenarios, providing a dedicated platform for product adaptation, technology research and development, and protocol iteration. These collective functions establish the station as an industrial development and incubation center.
In terms of support services, the station is equipped with battery reverse discharge detection gear. Employing non-intrusive testing techniques without requiring battery disassembly, a single routine charging procedure suffices to complete hidden hazard screening and state-of-health assessment for vehicle batteries. Subsequent initiatives will provide free routine battery health examinations for vehicle owners contributing their vehicles via V2G infrastructure within the demonstration program, Anhui Business Daily reported, quoting a representative of the administration and management of the State Grid Hefei Power Supply Company.
Against this industrial backdrop, since Hefei entered the initial phrase of Vehicle-to-Grid (V2G) development pilot cities approved by the nation in April of 2025, more emphasis was drawn toward core connectivity prototyping phased alignments infrastructure schemas via platforms built thereof to specific specialized purposes serving their objectives herewithin technology roadmap milestones achievements' implementations thus pursued as of those underlying values embodied hithertofully reflective herein...
