An intelligent monitoring system enables real-time battery status monitoring and predictive maintenance, ensuring stable and continuous operation.
To address the need for flexible technology adaptation in Europe’s energy transition, the product supports both 2-line and 3-line UPS configurations, with a comprehensive voltage range and communication protocol compatibility with mainstream UPS brands. Desay Battery’s solution also includes a multi-layer protective scheme that spans the battery cells, packs, cabinets, and systems, integrating material innovation, mechanical protection, and intelligent monitoring to create proactive defenses against safety hazards. With the company’s self-developed active safety battery cells, the solution has officially entered the era of “eight protective measures.” The cells utilize innovative PE + ceramic separator technology, fully passing national standard puncture thermal runaway tests; the PACK level is equipped with a perfluorohexane fire protection system and dual active defense mechanisms, while the cabinet level features fuse protection and directional explosion venting, along with efficient gas and water firefighting systems.
Economically, this solution has also made significant strides. Its innovative whole-cabinet transport scheme can reduce installation costs by up to 90%, while the high energy density lithium battery design decreases footprint by 70%, significantly enhancing space utilization. In the long run, the 15-year lifespan substantially lowers the total lifecycle cost, creating ongoing value for customers.
However, the primary challenge for Chinese companies in expanding into the European market lies in the requirements of the EU’s new battery regulations. Desay Battery has successfully navigated this challenge. During the exhibition, the company signed a strategic cooperation agreement with the internationally recognized certification organization TüV Rheinland to conduct comprehensive certification for its latest UPS lithium cabinet 2.0. The product will undergo multiple stringent tests, including CB 62619, CE LVD, CE EMC, and must comply with the newly implemented EU battery law and ROHS environmental directives.
