DIMAAG-AI and Toshiba have teamed up to introduce a new battery platform designed to address the rapidly changing power demands of AI data centers, while also providing backup power and grid support. The platform combines Toshiba's SCiB lithium titanium oxide (LTO) batteries with DIMAAG's ZettaWatt Power platform, which integrates energy storage, power conversion, and real-time control systems. The system is designed to support continuous 10C charge and discharge rates and is expected to have a service life of over 10 years.
Additionally, the system can smooth out the cyclical power fluctuations caused by computing workloads to less than 1% as seen by the grid. Since 2010, Toshiba has shipped over 100 million SCiB battery cells, and this battery technology has accumulated over a decade of field experience, which is exactly the direction the two companies plan to apply to high-duty-cycle data centers.
As the power demands of large computing facilities fluctuate, the need for such systems is increasing. Unlike traditional loads, computing workloads cause power consumption to fluctuate rapidly, which poses challenges for data centers and power grids. DIMAAG's ZettaWatt platform uses a modular 800 VDC architecture to manage these changes. As data center campuses expand, multiple units can be deployed in parallel. In addition to performing the traditional function of backup power, the platform is designed with multiple functions including load smoothing, low-voltage ride-through, demand response, and grid stabilization.

The battery system uses DIMAAG's active flow immersion cooling Zenius modules. Toshiba will provide SCiB battery cells, while DIMAAG will be responsible for designing, manufacturing, and integrating the battery system into the ZettaWatt platform. DIMAAG Chief Technology Officer Ian Wright said, "Energy storage for AI data centers must go beyond just responding to power outages. It must be able to absorb rapid load fluctuations, support grid ride-through, provide backup power, and not cause system constraints during multiple responses."
He added, "Combining Toshiba's established SCiB battery technology with DIMAAG's active flow immersion cooling Zenius modules into the ZettaWatt Power platform provides differentiated performance for the high-power, high-duty-cycle requirements of AI data centers."
The system's 10C capability is at the core of its design purpose. A 10C rate means the battery can theoretically charge or discharge its rated capacity in about one-tenth of an hour, or about six minutes, provided it meets the specified operating conditions. The two companies stated that SCiB battery cells can support simultaneous 10C charging and discharging when paired with a properly designed cooling system. This capability is designed to help the system respond to changes in power demand in a short period of time, without relying solely on the grid. According to DIMAAG, the platform also meets ERCOT's low-voltage ride-through requirements, allowing it to continue supporting facilities during certain grid disturbances, rather than just disconnecting.
Greg Mack, Senior Vice President and General Manager of the Power Electronics Division at Toshiba International Corporation, said, "This collaboration demonstrates how Toshiba's SCiB technology, with its continuous 10C charge and discharge capability, excellent cycle life, and proven safety record, can support the next generation of AI infrastructure." The two companies stated that this collaboration will expand SCiB-based energy storage into high-power applications that require frequent cycling, rapid response, and long-term operational life.
These capabilities are still in the ongoing stages of design, testing, and validation.
