According to our (Global Info Research) latest study, the global AI Data Center BBU Power Supply market size was valued at US$ 378 million in 2025 and is forecast to a readjusted size of US$ 906 million by 2032 with a CAGR of 9.0% during review period.
The AI Data Center BBU Power Supply is a distributed short-term energy storage and backup power supply device deployed near AI server racks, power racks, or DC buses. It mainly consists of lithium-ion battery modules, battery management systems, bidirectional DC conversion modules, control communication units, protection circuits, and thermal management structures. When there is an instantaneous interruption, voltage drop, or insufficient power supply in the mains, UPS, or power rack, BBU can quickly release electrical energy to provide power support for GPU, AI accelerator, and high-power server loads for seconds to minutes, allowing the equipment to maintain continuous operation, complete data storage, or wait for higher-level backup power to take over. Compared with centralized UPS, rack level BBUs are closer to computing loads, have shorter power supply paths, faster response speeds, and can be directly connected to rack DC busbars.
In 2025, global AI Data Center BBU Power Supply production reached approximately 993 K Units, with an average global market price of around US$ 370 per unit.
The AI Data Center BBU Power Supply is gradually upgrading from a backup device that only deals with power outages to a rack level dynamic energy storage node that combines fast backup, instantaneous power compensation, and voltage stability functions. Generative AI training and inference clusters use a large number of GPUs and accelerators, with high load power and fast changing speed, which may cause significant power fluctuations in a short period of time. Although traditional centralized UPS can bear long-term backup power for facilities, its ability to handle millisecond level power gaps is limited in situations where the load is far away and the power supply link is long; Rack level BBUs can quickly discharge close to the load, supplement power during peak periods, and reduce DC bus fluctuations. Panasonic has revealed that ultra large scale cloud service providers are promoting the configuration of BBUs per rack to cover power shortages during peak load periods and stabilize voltage. LITEON has also included high-efficiency BBUs in its core power product portfolio for AI data centers. The future market growth will mainly be driven by the continuous increase in AI rack power, the popularization of Open Rack architecture, the reduction of centralized UPS losses in data centers, and the demand for improving power supply availability. Products will develop towards higher voltage, higher power density, modularity, liquid cooling adaptation, intelligent status monitoring, and longer cycle life. The focus of competition will be on battery cell safety, charging and discharging efficiency, switching speed, thermal runaway protection, BMS algorithm, rack integration capability, and large-scale delivery capability. At the same time, the industry still faces challenges such as incomplete standardization of technical standards, long customer verification cycles, and strict safety requirements for high-power battery systems.
