YMIN Lithium-ion Supercapacitors Provide Millisecond-Level Protection for Server BBUs to Meet the Surge in AI Computing Power

The rapid development of artificial intelligence technology is driving exponential growth in global demand for AI computing power. Industry data shows that the global AI server market will exceed $80 billion in 2024 and is expected to increase by another 45% in 2025. The continued demand for computing power in scenarios such as large-scale model training and autonomous driving algorithm iteration has led to new challenges for data center power supply systems due to the high-frequency computing and ultra-high power consumption of AI computing infrastructure.

Against this backdrop, Shanghai YMIN Electronics Co., Ltd. will showcase its next-generation lithium-ion supercapacitor BBU solution at the upcoming 2025 ODCC Open Data Center Summit in Beijing, bringing innovative breakthroughs to data center energy management.

A recent adjustment by AI leader NVIDIA has attracted industry attention: the backup power supply (BBU) in its GB300 server has been upgraded from an optional feature to a standard feature. Behind this change lies the AI ​​server's extreme pursuit of power supply stability. The cost of adding supercapacitors and batteries to a single cabinet exceeds 10,000 yuan, but this investment is essential compared to the losses from power outages.

In actual operation, AI server power fluctuations are extremely extreme: a single GPU can instantly consume 1.4kW during peak computing, and the inrush current for the entire server can reach 10kW. Traditional UPS systems have a delayed response (typically hundreds of milliseconds) and a short cycle life (generally less than 100,000 cycles), making them unable to meet the stringent millisecond-level power supply requirements of AI computing loads. Once a voltage drop occurs, restarting large-scale model training can result in losses of hundreds of thousands of yuan, far exceeding the investment in power supply equipment.

To address this industry pain point, YMIN Electronics, after years of research and development, has launched a next-generation BBU solution based on lithium-ion supercapacitor (LIC) technology, achieving breakthroughs in multiple dimensions:

In terms of space utilization, the YMIN LIC solution is 50%-70% smaller and 50%-60% lighter than traditional UPSs. Taking a standard 42U server cabinet as an example, a traditional UPS requires 3-4U of space, while the YMIN solution only requires 1U. A single cabinet can accommodate an additional 2-3 AI servers, significantly improving data center space utilization and supporting high-density AI cluster deployments.

In terms of environmental adaptability and service life, this solution operates in temperatures ranging from -30°C to +80°C, making it suitable for data center environments with poor local heat dissipation or extreme climates. Its cycle life exceeds 1 million cycles, resulting in a service life exceeding 6 years, 5-8 times longer than traditional lead-acid batteries. Its charging speed is five times faster, with a zero to full charge time of just 15 minutes. These features reduce equipment replacement frequency and maintenance costs, optimizing the total cost of ownership (TCO) over the entire lifecycle.

In terms of power supply stability, the YMIN LIC solution provides the dual guarantees of "millisecond-level response and minimal fluctuations." Dynamic response time is controlled within 10 milliseconds, and voltage fluctuations are limited to ±1%. This prevents AI training tasks from being interrupted by voltage drops, effectively ensuring a lifeline for large-scale model training that requires weeks of continuous computation.

In practical applications, the YMIN LIC solution has already proven itself in numerous high-end projects. A single NVIDIA GB300 server cabinet requires 252 supercapacitor units, placing extremely high demands on product performance. YMIN's LIC modules, such as the SLF4.0V3300FRDA and SLM3.8V28600FRDA, utilize optimized electrode materials and packaging processes to achieve a capacity density of 8.5mAh per cubic centimeter and a response latency of less than 5 milliseconds. Their performance rivals that of leading international brands, making them a leading choice for domestically produced alternatives to high-end power supply equipment in domestic data centers. Currently, this solution has been piloted in intelligent computing centers such as Alibaba Cloud and Tencent Cloud, reducing power outage rates by 99.7% compared to traditional solutions and saving individual data centers over 10 million yuan in losses annually.

The upcoming 2025 ODCC Open Data Center Summit is expected to attract over 500 companies and 20,000 professional visitors. YMIN Electronics will feature an immersive experience zone at booth C10, dynamically simulating AI server power surge scenarios and visually demonstrating the millisecond-level response of its LIC solution. Onsite technical experts will explain the product's operating principles, adaptation solutions, and breakthroughs in localization. Visitors who book in advance will also receive consultation on customized power supply solutions.
