Data centre power architecture shifts as BBU batteries emerge as new battleground
Battery use is expanding beyond electric vehicles and energy storage systems to server racks as AI data centres push rack power density higher. Facility-level uninterruptible power supplies are seen as less able to handle rapid power swings, lifting demand for rack-level battery backup units, or BBUs, defined in open rack standards such as OCP Open Rack V3. Samsung SDI forecasts the global BBU market at $800 million this year, up more than 70 percent, while suppliers prepare new products and production.
