Flex, Musashi Energy to Develop Energy Storage for AI Data Centers

Flex and Musashi Energy Solutions, a group company of Musashi Seimitsu Industry Co., Ltd., announced an extensive collaboration to supply Flex-designed and manufactured capacitor-based Energy Storage Systems (CESS) featuring Musashi’s Hybrid SuperCapacitor (HSC) technology.

These systems are designed to integrate with server rack power systems to address significant challenges with utility power in artificial intelligence (AI) data centers. First to market with Musashi’s HSC technology, Flex has collaborated with Musashi to develop strategic technology and product development roadmaps for current and future products that enable hyperscale operators to mitigate utility power fluctuations in data centers deploying AI workloads.

Key features of the CESS include:
• The ability to support and balance power supply systems during large power transients.
• Efficient energy management and the reduction of large power transients or spikes. produced by AI workloads by alternately supplying and absorbing energy in its internal Hybrid Supercapacitors, which are supplied by Musashi.
• A significantly longer lifespan than current battery energy storage systems, with ability to provide multi-million charge/discharge cycles – essential for high performance capacity and dependability needed in the data center.
• A wide operating temperature and inherent safety through Musashi’s Hybrid SuperCapacitors, with cells able to operate in temperature ranges from minus 30 to over 70 degrees Celsius, plus UL 810A certification and completion of UL 9540A testing for thermal runaway at the cell level.

“We are proud to lead the charge in powering the next generation of AI innovation alongside Flex to address the power challenges needed to unleash capacity for explosive data center growth,” said Frank DeLattre, president of Musashi Energy Solutions in North America. “Our partnership with Flex for its new CESS product will bring reliable, efficient and scalable power solutions to the market.”

“Our collaboration with Musashi is central to developing our innovative CESS solutions to sustainably support the complex power demands of AI data centers worldwide,” said Mattias Jansson, VP of power solutions at Flex.
