Quick Takeaways
- Nio vehicle-to-grid battery swap stations demonstrated large-scale grid support capability during a China V2G trial.
- The trial highlighted how battery swap stations can act as distributed energy storage assets.
On January 22, Nio Inc took part in a large-scale vehicle-to-grid trial in eastern China, examining how its battery swap infrastructure can supply electricity back to the power grid during peak demand periods.
The trial was conducted across Jiangsu, involving a total of 70 energy facilities. These included 56 charging stations and 14 battery swap stations equipped with vehicle-to-grid functionality, marking a significant expansion in scale compared to earlier tests.
Nio Vehicle-to-Grid Battery Swap Stations Deliver Peak Power Output
Six fourth-generation Nio vehicle-to-grid battery swap stations participated in the trial in Nanjing, according to a WeChat update published by GCL Energy Technology.
Retrofitted jointly by GCL and Nio with V2G capabilities, these stations achieved a combined peak power output of 1,539.85 kilowatts during evening peak hours. This accounted for 15% of the total discharge share recorded during the test window, underlining the grid contribution potential of battery swap infrastructure.
Trial Scale Expands Sharply Over Previous Tests
The latest vehicle-to-grid trial represented an 80% increase in scale compared with a similar test conducted in 2025. By integrating both charging stations and V2G-enabled battery swap stations, the project demonstrated how mixed EV infrastructure can collectively support grid stability during high-load periods.
Battery swap stations, beyond their primary role of enabling rapid energy replenishment for electric vehicles, also operate as localized energy storage systems. This allows them to participate in grid frequency regulation and short-duration power balancing.
Nio’s Growing Vehicle-to-Grid Deployment Strategy
Nio began exploring power discharge from its battery swap stations to the grid in China as early as 2022. The company has steadily expanded these efforts, positioning vehicle-to-grid technology as a core component of its energy ecosystem strategy.
In late 2024, Nio and GCL collaborated to launch Suzhou’s first carbon-neutral battery swap station, reinforcing the role of swap infrastructure in sustainable energy systems. Internationally, Nio’s battery swap stations in Sweden received approval last November to participate in local grid frequency regulation programs.
Expansion of V2G Charging Infrastructure in Major Cities
In January 2024, Nio introduced 10 vehicle-to-grid destination charging stations in Shanghai, marking the first deployment of such facilities in the company’s headquarters city. This move complemented its battery swap-based V2G efforts and signaled broader ambitions in EV-grid integration.
The Jiangsu trial highlights how Nio vehicle-to-grid battery swap stations can serve as flexible energy assets, supporting grid resilience while extending the functional value of electric vehicle infrastructure beyond mobility alone.
