Empowering Green Mobility: Exencell's Advanced Energy Storage Technology Supports NIO Charging and Battery Swap Stations in Dujiangyan, Sichuan
With the widespread adoption of new energy vehicles, range anxiety is being alleviated by the increasingly sophisticated charging infrastructure. Behind this efficient charging capability, energy storage systems are playing an indispensable 'super heart' role.
Recently, the NIO charging and battery swap station project in Dujiangyan City, Sichuan Province—known as the 'Source of Tianfu' —has officially commenced operations. In this initiative, Exencell Energy Storage partnered with Hanzhou to deploy a high-performance 200kW/430kWh energy storage system, providing robust support for sustainable mobility.

Many ordinary users might wonder: Since battery swap stations are designed to charge batteries, why is there an additional large-scale 'power bank' installed?
In actual operation, charging and battery swapping stations face massive instantaneous electricity demand during morning and evening peak hours, which not only strains the local power grid but also drives up operational electricity costsExencell's energy storage system perfectly addresses this pain point:
Peak shaving and valley filling to reduce costs: Energy storage systems can 'absorb' electricity during off-peak hours at night and release it to charging stations during daytime peak hours when electricity prices are high. This not only alleviates grid pressure but also significantly reduces the daily operational electricity costs for charging stations.
An ideal alternative to grid expansion: In older urban areas or regions with limited grid capacity, direct capacity expansion incurs prohibitively high costs. The integration of energy storage systems effectively adds a local power buffer pool to the station, enabling simultaneous charging and battery swapping for multiple vehicles without requiring costly grid upgrades.
Hardcore product: Exencell 280Ah Excellence battery
The project's successful implementation is underpinned by cutting-edge core technologies. The energy storage system at NIO's Dujiangyan battery swap station exclusively utilizes 280Ah lithium iron phosphate (LFP) cells, independently developed by Exencell Energy Storage.
As the core component of energy storage systems, our 280Ah cells offer the following industry-leading advantages:
Ultimate Safety: Featuring high-stability materials and advanced thermal management design, the system maintains optimal cell temperature even in complex outdoor temperature variations, effectively eliminating thermal runaway risks at the source.
Exceptionally long lifespan: With an exceptionally high cycle count, it ensures stable returns throughout the project's lifecycle while reducing maintenance and replacement costs in later stages.
High energy density: Within compact station spaces (as seen in the on-site photos of the space-saving outdoor cabinets), it achieves 430kWh of storage capacity, perfectly meeting the space-constrained requirements of urban charging and battery swap stations.
Strong partners, building a zero-carbon future
The successful delivery of the Dujiangyan project stands as another landmark achievement in the deep collaboration between Exencell Energy Storage and Hanzhou. We deliver not only high-quality products but also comprehensive, reliable services spanning solution design, equipment commissioning, and grid integration. The infrastructure support provided to industry-leading new energy vehicle manufacturer NIO further demonstrates the market's high recognition of Exencell's energy storage technology capabilities.
The integration of "photovoltaic-storage-charging-swapping" is a pivotal component in building the future of next-generation power systems. Exencell Energy Storage will continue to uphold the philosophy of technological innovation, delivering safer, more efficient, and smarter energy storage solutions to global customers.
