Explore advanced power solutions for modern data centers in this 19-minute conference talk from the Open Compute Project. Learn about two critical technologies - the Capacitor Bank Unit (CBU) and Battery Backup Unit (BBU) - designed to address the growing power demands and load fluctuations of expanding data centers and high-performance GPUs. Discover recent advancements in Li-ion cells and Li-ion capacitors, and understand how future improvements in these technologies will support next-generation GPU requirements. Examine the safety-critical labyrinth structure design for rack-installed BBUs that complies with UL9540A fire prevention standards. Understand how the CBU delivers high power density in a compact form factor while sharing common battery-cell can designs with BBUs for supply chain efficiency. Review the technology roadmap including liquid cooling solutions for thermal management and low-resistance capacitor innovations to enhance CBU output performance, all aimed at creating safe, compact, and high-performance energy systems for future data center infrastructure.
