In the context of the deep integration of artificial intelligence, cloud computing and big data technology, the global AIDC construction has entered an outbreak period. Behind the surge in computing power is the exponential increase in power density, the nearly stringent power continuity requirements, and the pursuit of extreme energy efficiency.
on April 1, Nandu power supply released a new generation of backup power system -- AIOnpower X-Rate, specially built for AIDC scenarios. With a comprehensive breakthrough from core materials to system architecture, the system redefines the energy base of AIDC in the computing era with the three core advantages of "ultra-high power, extreme safety and long-term cycle.
01 millisecond response at 10C ultra-high magnification
facing the load fluctuation of AIDC cabinet above 100kW, power performance is the core yardstick to measure the value of standby power system. The Nandu AIOn X-Rate achieved a major breakthrough in this dimension.
the system uses lithium iron phosphate batteries specially developed for high-power scenarios to support 10C ultra-high rate discharge with 0 delay response. 10C has the same discharge capability as 1C, showing excellent rate performance.
thanks to the innovation of the material system, the single cabinet power of the system exceeds 600kW, and the power density of the battery core exceeds 1900 W/kg, which can release huge energy in a very short time. In addition, the pulse cycle life of the system is particularly amazing, with more than 200000 times of 500ms pulse discharge, which perfectly adapts to the frequency modulation requirements of AIDC UHF.
at the material level, AIOn X-Rate introduces high entropy electrolyte technology to reduce the size of ion clusters by reconstructing solvation structure, making it easier for ions to get out of bondage and move rapidly, thus greatly improving ion transmission efficiency.
At the same time, through the introduction of capacitive characteristics through the innovation of the material system, the system has constructed a chemical and physical hybrid energy storage mechanism of "lithium-free plus electric double layer capacitor as a supplement.
this composite system of battery-type energy storage and capacitive energy storage effectively improves the platform voltage of short-term high-rate discharge and ensures that the voltage of the system does not collapse when dealing with pulse impact load.
compared with the traditional lead-acid battery scheme, AIOn X-Rate saves up to 70% of its floor space and 50% of its deployment time while achieving the same or even stronger power backup capability, thus freeing up more computing space for data centers with an inch of land and money.
02 safety is the foundation line from the material source
in AIDC scenario, extremely high power density and uninterrupted operation requirements make safety the sword of Damocles hanging over the top of the industry. Nandu AIOn X-Rate system has realized the leap from passive protection to active prevention in safety design.
the AIDC special 55Ah high-rate battery carried by the system uses solid-liquid mixed electrolyte, and through the cooperative mechanism of" solid-state physical barrier + liquid interface optimization ", the risks of thermal runaway and leakage combustion are greatly reduced, and the electrochemical performance and physical safety are highly unified.
in addition, AIOn X-Rate effectively reduces the internal resistance of the battery through the SNS three-dimensional collaborative design technology of the battery, reduces the heat generation during high-rate discharge from the source, and ensures the electrical safety in the whole life cycle in combination with the full-dimensional insulation protection design of the system.
03 cycle is long-term durability and intelligent maintenance
as an infrastructure for 7x 24 uninterrupted operation, the cycle life and maintenance convenience of the standby power system are directly related to AIDC's operating cost and reliability. The Nandu AIOn X-Rate system was designed with full life cycle value in mind.
AIDC special battery uses graphite material with small particle size and stable interface as negative electrode, which effectively suppresses the volume expansion problem of the battery in long-term cycle, reduces the expansion rate by 30%, and at the same time reduces the first irreversible lithium consumption and the lithium consumption by 40%, laying a solid foundation for the long life of the battery.
aiming at the consistency management of battery modules, AIOn X-Rate innovatively adopts the system-level power supply active equalization strategy to dynamically equalize the capacity of all cells in the system to the same horizontal line, effectively prolonging the service life of the system compared with the traditional in-module equalization.
The system also externally installs the core monitoring unit (BMU). This humanized design greatly simplifies the operation and maintenance process. In addition, the insulation maintenance panel set up in the system physically isolates the high voltage from the maintenance personnel, and supports point-to-point disassembly and maintenance, which simplifies the operation and maintenance process and maximizes the operation safety of the operation and maintenance personnel.
04 END
the release of the Nandu power supply AIOn X-Rate is a redefinition of the AIDC backup power infrastructure. In the era of computing power is productivity, Nandu Power has upgraded the safety bottom line, power ceiling and cycle life to a new dimension with this product, providing a more solid and efficient energy-using cornerstone for the development of artificial intelligence and digital economy.
In the future, with the continuous acceleration of AIDC construction, the next generation of standby power system represented by AIOn X-Rate will become an indispensable "invisible engine" to drive the digital world ".
