en.Wedoany.com Reported - Hezhong Huineng has launched the CBU-800V/600KW supercapacitor module for AI server HVDC applications, specifically designed for 600kW-level high-power AI cabinets under an 800V high-voltage DC power supply architecture. It aims to address challenges such as instantaneous power surges, high-frequency load fluctuations, and significant peak power variations in scenarios like AI large model training and computing power inference.
This module features ultra-high-rate rapid charge and discharge capabilities, stably supporting continuous full-power operation of a single cabinet and precisely matching the dynamic power demands of high-power computing equipment.
In terms of technical characteristics, the CBU-800V/600KW module can respond to GPU load fluctuations within milliseconds, quickly smoothing extreme power fluctuations in AI computing power, thereby reducing peak power supply pressure in data centers by 30%. The module supports independent Sidecar deployment, separating the capacitor unit from the main computing cabinet. On one hand, this frees up space in the main cabinet to increase GPU deployment density; on the other hand, it decouples power supply from heat sources, reducing cabinet cooling pressure and optimizing data center energy consumption. The product has no risk of thermal runaway or chemical degradation, is compatible with the 800V high-voltage architecture, features a simplified system structure with high stability, offers a cycle life of millions of cycles, and supports high-frequency charge and discharge to reduce long-term operation and maintenance costs. Additionally, the module can form a high-low configuration with rack-mounted BBUs, where the supercapacitor handles millisecond-level transient voltage stabilization and power buffering, while the BBU provides short-term backup support during power outages. This replaces traditional centralized UPS systems, eliminating multi-stage power conversion losses, improving power supply efficiency by 2-3%, and adapting to the 800V HVDC distributed power supply architecture.
During AI large model training and inference, GPU loads exhibit millisecond-level step pulse characteristics, with power fluctuation amplitudes reaching over 15 times the steady-state level. Traditional UPS systems typically have response times in the millisecond to second range, unable to keep up with such instantaneous changes. Based on physical electric double-layer adsorption, this supercapacitor module offers microsecond-level (less than 1ms) charge and discharge response capabilities. When a sudden surge in GPU computing power causes a current spike, the module can immediately release stored high-power electrical energy to compensate for grid supply delays; when the load drops sharply, it can quickly absorb excess energy, converting sharp power peaks into smooth curves.
This 800V/600kW CBU module supports cross-cabinet networking to form a global virtual energy storage pool. During peak power moments when AI training clusters start up in batches, it can uniformly dispatch the energy storage capacity of all modules, reducing the overall cluster peak grid load by 30% and helping data centers avoid high demand charges. For the upgrade needs of existing 400V data centers, the module does not require replacing the original main grid incoming lines. It can support 600kW high-power computing on old racks simply through retrofitting, while freeing up computing deployment space within the cabinets.
