Desay Battery Showcases Cutting-Edge Energy Storage Solutions at Battery Expo 2025
From June 25 to 27, 2025, Desay Battery, a frontrunner in global energy storage solutions, made a notable impact at Battery Expo 2025 held in Vietnam. The company displayed its self-developed energy storage cells, both residential and commercial storage systems, and innovative containerized CI solutions, all of which resonated with the growing energy demands of Vietnam.
A Growing Demand for Energy Storage in Vietnam
Vietnam has been facing significant challenges due to its aging power infrastructure and increasing industrial electricity restrictions. This has led to an unprecedented demand for energy storage solutions. Market projections indicate that the energy storage sector is expected to experience a remarkable 35% year-over-year growth, potentially surpassing USD 500 million in 2025. Adding to this, the rapid escalation of the electric vehicle (EV) market has intensified the demand for lithium batteries, aligning perfectly with Desay Battery's offerings.
Innovative Solutions on Display
Desay Battery's containerized energy storage systems come in various configurations tailored for different needs, whether small, medium, or large scale. These systems boast high-capacity cells, intelligent energy management systems (EMS), and capabilities supporting PV-diesel integration as well as peak-valley arbitrage. Among the star features was their 5MWh liquid-cooled container system, which meets UL9540A safety standards and is designed for easy deployment across grid, industrial, and microgrid environments.
Additionally, their high-rate uninterruptible power supply (UPS) battery systems, designed specifically for data centers, provide a significant advantage by saving up to 70% in space and cutting lifecycle costs. These innovations are crucial for enhancing infrastructure resilience in the face of escalating energy demands.
Comprehensive Design and Manufacturing
Desay Battery's success is backed by a robust design and manufacturing framework. The company employs an innovation-driven quality management system, structured around a comprehensive SIPOC (Suppliers, Inputs, Process, Outputs, Customers) model. This model integrates a meticulous eight-layer safety design that includes thermal and fire management based on its intelligent EMS.
Every battery cell is subjected to puncture testing, ensuring durability and safety. Furthermore, both PACK and system levels incorporate proactive defense mechanisms, intelligent suppression features, and dual fire control protocols. The company operates an extensive vertically integrated production chain, enabling a seamless journey from cell production to system integration.
Future Expansion Plans
With a planned production capacity of 20GWh and the inclusion of over 14 automated modules and PACK lines, Desay Battery's intelligent factory spans 100,000 square meters. This setup ensures an annual capacity exceeding 25GWh for system integration. It prides itself on its CCS (Containerized Solutions) design, adaptive EMS technology, and multi-layered fire safety standards that empower large-scale, customizable energy storage solutions suitable for both commercial and utility applications.
Having garnered over two decades of experience, Desay Battery boasts a stellar portfolio of high-performance lithium battery solutions that cater to a diverse range of global clients, including top-tier OEMs and integrators. The company's dedication to quality and performance has recently been recognized with appearances on Bloomberg's Q2 2025 Energy Storage Tier 1 list, further solidifying its leadership and influence in the industry.
As Vietnam continues to elevate its energy storage sector, Desay Battery is poised to play a pivotal role in shaping the country's energy landscape. By establishing local partnerships and delivering innovative solutions, the company is not only addressing the present energy challenges but also paving the way for a sustainable energy future.
