Accurate High-Voltage Sensing for 800V EVs and Data Centers

Why BBU Cells Matter More Than Ever in the AI Era As AI workloads continue to grow, we often hear discussions about GPUs, power supplies, cooling systems, and rack architecture. But one critical component is still underestimated: the battery cell inside the Battery Backup Unit (BBU). A reliable BBU is not just about storing energy—it is about delivering power instantly and consistently when the system needs it most. For BBU applications, selecting the right cell involves much more than capacity. Key considerations include: ✅ Low DCIR for fast power delivery ✅ High pulse power capability ✅ Excellent cell consistency ✅ Long calendar life ✅ High safety under demanding operating conditions ✅ Stable performance over a wide temperature range As AI data centers move toward higher rack power and more demanding workloads, battery cells will increasingly become a key enabler of system reliability—not just another component. Over the coming weeks, I'll be sharing my thoughts on: BBU technology trends Cell selection for AI infrastructure LFP vs. NCM in BBU applications Why cell design matters at the system level Insights from the cylindrical battery industry Looking forward to exchanging ideas with professionals working on AI infrastructure, data centers, and energy storage. #AI #DataCenter #Battery #BBU #LithiumIon #EnergyStorage #PowerSystems #BatteryTechnology #CylindricalCells #AIInfrastructure

Proof over promise. We don’t ask customers to rely solely on a specification sheet. We invite them onto our manufacturing floor to see the equipment and verify its performance themselves. This week, a major hyperscale customer completed a factory witness test of our HD-RPP at our Ohio manufacturing facility. Load performance, breaker interoperability and dimensional accuracy were verified in person before shipment. As the first 1,200A remote power panel on the market, the HD-RPP represents a significant advancement in white space power distribution. It delivers 1,200A capacity in a compact 40-inch by 16-inch footprint, with a patent-pending universal adapter designed to accept ABB, Square D, Siemens, Eaton and LS breakers within the same chassis. One platform. Multiple breaker manufacturers. Greater flexibility for customers deploying critical AI infrastructure at scale. Every HD-RPP is engineered and manufactured in the United States, providing greater control over quality, supply chains and the components that matter most. Built here. Tested here. Ready for the demands of AI infrastructure. #missioncritical #AIInfrastructure #DataCenters #Hyperscale #Accelevation

As AI workloads continue to drive higher power densities, the conversation often centers on GPUs, liquid cooling, and electrical capacity. Less attention is given to the mission-critical infrastructure supporting those systems. Critical electrical connections experience constant thermal cycling, vibration, and joint relaxation. If bolt preload is lost over time, electrical resistance can increase, generating heat and compromising long-term reliability. Maintaining clamp load is one reason Belleville spring washers are commonly specified in applications such as switchgear, busbar connections, transformers, battery energy storage systems, and cooling equipment. While these components are rarely visible once equipment is assembled, they play an important role in maintaining reliable bolted joints throughout the life of the system. Visit https://bit.ly/4fHEJqP to explore where Belleville washers are used, common application considerations, and how they contribute to reliable power infrastructure. As demand for AI infrastructure continues to accelerate, understanding the fundamentals of mechanical joint reliability will become increasingly important across the data center ecosystem.

QuietEdge is entering its next phase. We develop control IP and reference DC power architectures for power systems where conditions change faster than conventional centralized supervision can respond. Our first market is AI data-center rack power. As compute becomes denser and more dynamic, power infrastructure faces more than a capacity or efficiency problem. It faces a response problem. QuietEdge moves critical behavior closer to the converter: Local observation. Distributed coordination. Bounded response. Fault-contained modularity. Higher-level EMS, UPS, BESS and grid systems remain essential. QuietEdge addresses the faster local layer closest to the electrical event. Over the past year and a half, the work has progressed from architecture and reference models into embedded execution, patent filings and an active SiC power-hardware validation program. Our core modular DC architecture is now patent pending. AI rack power and emerging 800 VDC architectures are the beachhead. Solid-state transformers provide a natural adjacent path for broader control-IP integration. Our business model is intentionally capital efficient: Hardware validates the behavior. Licensing scales it. We welcome conversations with power-electronics OEMs, data-center infrastructure companies, SST developers, semiconductor partners, manufacturers, and strategic investors. Autonomous Power Begins at the Converter. #PowerElectronics #AIInfrastructure #DataCenters #800VDC #DCPower

🔷 800V is no longer just an EV story. AI data centers are now undergoing the same transformation. As AI adoption accelerates, data centers are facing many of the same challenges that have driven innovation in the EV industry: ✅ Rising power demand ✅ Increasing thermal management complexity ✅ Growing copper usage ✅ Pressure to improve energy efficiency To address these challenges, the industry is moving toward 800VDC power architectures and accelerating the adoption of next-generation power semiconductors such as SiC and GaN. However, higher voltage also brings new reliability challenges: ⚠️Insulation breakdown ⚠️Partial discharge ⚠️ Leakage current ⚠️ EMC issues The next competitive advantage will not be determined by how high the voltage can go. It will be determined by how confidently we can prove that high-voltage systems will operate safely and reliably throughout their lifetime. In the high-voltage era, insulation reliability evaluation and long-term testing are becoming strategic differentiators, not just validation activities.
