Truewin Technology, a leading Taiwanese energy storage system (ESS) integrator and battery technology provider, has further expanded its strategic presence in Japan’s energy and data infrastructure sectors. Following its three-party alliance with Daiei Sangyo Group and Formosa New Energy Japan in October, Truewin has now formalized a deeper collaboration with Daiei Sangyo Kaisha,Ltd., CXIT Inc., and KONST Corp. The multi-party agreement was signed during a ceremony held at the Gunma Prefectural Government Office, marking a significant milestone in Japan–Taiwan cooperation on next-generation energy and AI infrastructure.
Truewin Technology has an established track record in high-performance lithium iron phosphate (LFP) ESS and battery integration. Holding over 80%market share in Taiwan’s UPS lithium battery segment, Truewin has deployed more than 600 MWh of systems within the world’s largest semiconductor fabs—operating continuously for over seven years under mission-critical conditions. This experience positions Truewin as a trusted technical partner in high-availability, high-reliability energy environments.
With AI data centers driving unprecedented power consumption and thermal loads, power quality and supply resilience have become essential to maintain computational stability. Under this partnership, Truewin will deploy semiconductor-grade power protection and ESS technology to support AI supercomputing facilities in Japan—enabling a power architecture that is highly efficient, ultra-safe, and engineered for long-duration reliability.
Through its “materials-to-system” vertical integration model, Truewin will supply Taiwan-made high-safety LFP battery cells, its in-house designed battery management system (BMS)—already proven in wafer fabs—and STOBA Inside liquid-cooling thermal technology, co-developed with Taiwan’s Industrial Technology Research Institute (ITRI), delivering enhanced heat dissipation and energy efficiency essential for high-density AI power systems.
Beyond data center applications, the collaboration will evolve into broader renewable energy and resilience domains under the Daiei Sangyo Group,including grid flexibility, behind-the-meter storage, and disaster readiness.Future initiatives include virtual power plants (VPPs), distributed energy resource management (DERMS), and flexible grid interconnections to meet Japan’s accelerating renewable integration challenges and the escalating electricity demand driven by AI infrastructure growth.
Speaking at the ceremony, Dr. Y.F. Lee, Chairman of Truewin Technology,remarked: “Energy storage is no longer just an auxiliary power solution – it is the backbone of modern computing and renewable integration. Truewin is honored to bring semiconductor-grade safety and reliability into Japan’s AI and energy ecosystem. This milestone not only represents the convergence of Japanese and Taiwanese industrial strengths, but also lays the foundation for a new era in sustainable energy and high-performance computing.”
Truewin Technology remains committed to its core values of Safety,Reliability, and Innovation as it continues to collaborate with partners in Japan and globally to build a safe, intelligent, and sustainable energy future.
