HGUHVC — Lithium Battery Cabinet System for Data Centre and HVDC Plants

Two pre-engineered 51.2 V LiFePO4 cabinets — 51.2 kWh and 102.4 kWh per cabinet — for 192 V to 512 V DC bus

When the load is a Tier-III data hall or an AI-compute cluster, the battery plant can no longer be a string of 12 V monoblocs in a remote battery room. The HGUHVC family is the lithium-cabinet branch of the HGU platform: two pre-engineered LiFePO4 battery cabinets — 51.2 kWh and 102.4 kWh per cabinet — that drop into a 600 × 1100 × 2000 mm footprint, parallel up to 16 cabinets for multi-megawatt-hour strings, and connect directly to the data-centre DC bus. Working voltage 400–576 Vdc per cabinet, system DC-bus coverage 192–512 V, power range 10–800 kW, full 3-level BMS, Modbus TCP/RTU and CAN 2.0B. It is the cabinetised answer to the modern DC plant.

What is the HGUHVC?

HGUHVC is the cabinetised LiFePO4 backup family for the modern data-centre DC plant. Each cabinet is a self-contained 16-module string: 1P16S (51.2 V 100 Ah) for the HVC512100XC1 cabinet, or 2P16S (51.2 V 200 Ah) for the HVC512200C01 cabinet. Cabinets parallel up to 16 for multi-megawatt-hour storage strings. Every cabinet ships with its own 3-level BMS — cell-level in every module, rack-level aggregating module state, and system-level managing parallel strings and grid interaction. Communications are Modbus TCP/RTU and CAN 2.0B for direct integration with the data-centre DCIM, EMS or SCADA stack.

Frequently asked questions

1. Why is the cabinet working voltage 400–576 Vdc but the system DC bus only 192–512 V?

The 400–576 Vdc window is the operating envelope of a single HGUHVC cabinet (a 1P16S or 2P16S string). The 192–512 V system DC-bus coverage is the total span supported when cabinets are paralleled and configured for different system voltages — covering the common 192 V, 240 V, 336 V, 384 V, 432 V, 480 V and 512 V battery plants in data-centre UPS systems.

3. Is lithium-ion safer than valve-regulated lead-acid in a data centre?

In modern data-centre duty, yes — LiFePO4 is thermally stable below 200 °C and does not suffer thermal runaway under normal operation. The HGUHVC cabinet ships with cell-level BMS, system-level BMS, a fire-suppression system using FK-5-1-12 perfluorinated ketone, and module-level fusing. Combined with the elimination of acid spill containment and the smaller footprint, the total safety profile is favourable to VRLA in most installations.

4. How long does an HGUHVC cabinet last in UPS duty?

Design life is 15–20 years in float-standby UPS duty, with over 6000 cycles at 80 % depth of discharge. Real-world life depends on depth of discharge, ambient temperature, and cycle frequency. The BMS tracks state-of-health per module and predicts remaining useful life.

5. Can HGUHVC replace a VRLA battery string in an existing UPS?

Yes, in most cases. The cabinet footprint (600 × 1100 × 2000 mm) is similar to a 19-inch battery rack. The working voltage window covers the common VRLA UPS strings. The BMS protocols (Modbus TCP/RTU, CAN 2.0B) integrate with the major UPS BMS gateways. Site-specific integration is required for BMS handshaking with legacy UPS controllers.

6. What fire suppression does the cabinet include?

Every HGUHVC cabinet ships with FK-5-1-12 (perfluorinated ketone, also known as Novec 1230) fire suppression — an all-fluorinated, clean-agent gas that extinguishes a lithium fire without damaging the cells or the data-hall equipment. The suppression system is module-level and triggered by the cabinet BMS.

7. Can cabinets be paralleled up to 16 for multi-megawatt-hour storage?

Yes — up to 16 HGUHVC cabinets can be paralleled in a single string for multi-megawatt-hour storage. The system-level BMS manages string balancing, state-of-charge equalisation, and grid interaction. Common configurations are 4-cabinet, 8-cabinet and 16-cabinet strings.

8. How is HGUHVC shipped?

HGUHVC cabinets are classified UN3480 (lithium-ion batteries) or UN3536 (lithium-ion batteries packed with equipment) depending on configuration, and require specialised transport. We provide the MSDS, the UN test summary, and the air/sea/road transport classification you need for your destination market.

9. Is the HGUHVC compatible with integrated power systems like HVDC plants?

Yes — HGUHVC is rated for integration with HVDC, UPS, DC plant and integrated power systems (such as the 巴拿马电源 architecture common in hyperscale data centres). The BMS exposes Modbus TCP/RTU and CAN 2.0B for direct SCADA/EMS integration.

10. What is the warranty?

Standard warranty is five years from date of shipment, conditional on storage, commissioning and operating-temperature records being kept. Extended warranty to 10 years is available on request. The BMS maintains the operational data needed for any warranty claim.
