‌Energy Storage Container

Four Core Functions for Data Centers

1. Uninterruptible Emergency Backup Power (Core Requirement)

Switches to backup mode within milliseconds during grid flickers or outages, acting as a UPS backup to bridge the gap until diesel generators start. High-capacity units can independently support IT loads for hours, meeting zero-interruption requirements for disaster recovery, financial services, and computing operations.

2. Peak Shaving and Valley Filling; Significant Electricity Cost Reduction

Charges during off-peak hours and discharges during peak hours to reduce peak grid demand and lower basic electricity charges. When paired with on-site solar PV generation and self-consumption, large IDCs can achieve annual electricity cost savings in the millions.

3. Renewable Energy Integration & Grid Support

Stores surplus solar or wind energy to create campus microgrids. Features grid-forming and black-start capabilities, allowing for autonomous power network establishment during total grid failure—ideal for remote computing campuses. Can also participate in grid ancillary services (such as frequency and voltage regulation) to generate additional revenue.

4. Smoothing Load Fluctuations; Improving Power Quality

AI servers experience extreme instantaneous power fluctuations; the energy storage container rapidly absorbs and releases power to stabilize bus voltage and suppress harmonics, protecting precision computing equipment and reducing the need for grid capacity expansion investments.

Core Advantages (Compared to Traditional UPS Battery Rooms)

Rapid Deployment: Factory prefabrication and pre-commissioning reduce on-site construction work by 70% and shorten delivery cycles by 30%. While traditional civil-engineered storage rooms take months to complete, these containers can be hoisted, connected, and put into operation within days, making them ideal for rapidly expanding intelligent computing projects. Ultra-compact Footprint: An integrated layout saves 40% of the space required by separate PCS and battery room configurations. Units can be placed in outdoor open areas, on rooftops, or in facility corners without occupying valuable core rack space (crucial given the high land costs for data centers).

Safety Isolation: The battery system is housed in an independent enclosure physically separated from the IT room; this prevents thermal runaway risks from propagating to servers and significantly alleviates fire safety requirements for the data center.

Flexible Modular Expansion: Containerized units can be added in batches aligned with rack scaling; the system supports hot-swappable parallel connections, allowing for phased deployment of computing power without the need for upfront investment in the total energy storage capacity.

Low Full-Lifecycle Cost: Liquid cooling extends battery lifespan, while integrated O&M simplifies management; a DC architecture reduces line losses by 60%, lowering the total cost of ownership (TCO) by approximately 20%.

Strong Environmental Adaptability: Outdoor IP55-rated, corrosion-resistant, and dust-proof design allows for direct deployment in diverse environments, including cold northern climates, hot and humid southern regions, and coastal areas prone to salt spray.

Typical Application Scenarios

New Large-scale Intelligent Computing/AIDC: Paired with 5–50 MWh energy storage containers and 800V DC power supply; integrates peak shaving, emergency backup, and PV-plus-storage capabilities.

Legacy IDC Retrofitting: Outdoor container addition enables rapid power capacity expansion without modifying existing civil infrastructure.

Edge Data Centers / Campus Computing Nodes: Small-scale 1–2 MWh containers providing microgrid power for off-grid or weak-grid scenarios.

Core Facilities for Finance, Government, and Telecom Operators: A combination of flywheel and lithium-battery containers provides millisecond-level uninterruptible power alongside long-duration disaster recovery backup.

Zero-Carbon Data Centers: Integrated PV and energy storage containers enable 100% self-consumption of green electricity.
