From April 10 to 12, the 13th Energy Storage International Summit and Exhibition (ESIE2025), the annual event of the global energy storage industry, was held in Beijing Capital International Convention and Exhibition Center. As an innovation pioneer in the field of energy storage, Qualtech made a stunning debut with a number of cutting-edge technologies and products, and became one of the focuses of attention at the exhibition.
Qualtech, founded in 2011, headquartered in Hangzhou, Zhejiang Province, is a company focused on the development, design, production and sales of new energy vehicle BMS and energy storage 4S+C core products. At the same time, it provides energy storage system integration, optical storage and charge integration system, intelligent energy management system, micro-grid system in various scenarios and other overall solutions and implementation services of the national high-tech enterprises, and won the title of the third batch of specialized and special new "little giant" enterprises by the Ministry of Industry and Information Technology. The company has been deeply engaged in the industry for 14 years, and has made remarkable achievements in the field of energy storage by relying on profound technology accumulation and innovation capabilities. Its products are widely used in many fields such as new energy vehicles and energy storage systems, making important contributions to promoting the development of green energy.
At this ESIE2025 exhibition, Qualtech brought many innovative exhibits, fully demonstrating its strong strength in energy storage technology. Among them, 4S+C full stack self-developed technology is undoubtedly one of the highlights of ***. The technology covers BMS battery management system, EMS energy management system, PCS energy storage converter, TMS immersion temperature control system and Cloud big data intelligent cloud platform, realizing the independent research and development of the whole chain of energy storage system from core components to overall solutions. This full-stack self-developed mode not only ensures a high degree of coordination and optimization between the systems, but also can be flexibly customized according to customer needs, providing efficient and reliable solutions for energy storage applications in different scenarios.
In addition, TMS immersion temperature control system is also a highlight of Qualtech booth. The system uses advanced submerged cooling technology to completely immerse the battery cell in the insulation coolant, effectively overcoming the traditional energy storage refrigeration technology faced with low heat exchange efficiency and poor temperature consistency. With this innovative temperature control method, the TMS system can significantly improve the overall safety and service life of the energy storage system, while significantly reducing operating costs, providing a solid guarantee for the economy and reliability of energy storage projects.
By directly immersing the battery module in the special coolant, Qualtechi's submerged liquid cooling technology achieves efficient heat transfer and uniform temperature distribution, accurately solving the temperature rise problem faced by the battery in the process of high power charge and discharge, and further enhancing the safety and stability of the energy storage system. The application of this technology will bring a new experience for the energy storage system in terms of high performance and high reliability, and effectively promote the development of energy storage technology to a higher level.
Active balanced BMS, as another core technology of Qualtech, also attracted a lot of attention at the exhibition. The system can monitor the status of each cell in the battery pack in real time, and ensure the voltage and power balance between the cell through the active equalization technology, so as to improve the overall performance and service life of the battery pack. This technology has a wide range of application prospects in new energy vehicles and energy storage systems, and is of great significance for improving the safety and reliability of battery systems.
Energy storage high pressure box, PCS, EMS system and other products were also exhibited at the exhibition, showing the complete energy storage system solution of Qualtech. These products cooperate with each other in technology to form an efficient, intelligent and safe energy storage system, which can meet the needs of various application scenarios such as industrial and commercial storage and container energy storage. Among them, the 4S+C series industrial and commercial storage and container energy storage solutions, with its excellent performance and flexibility, provide users with customized energy storage and management solutions to help enterprises achieve energy conservation and emission reduction and optimize energy utilization goals.
Qualtech's wonderful performance at the ESIE2025 Energy Storage International Exhibition fully demonstrated its technical strength and innovation ability in the field of energy storage. Through the display of a series of advanced technologies and products, as well as the release of submerged liquid cooling technology, Qualtech not only brought new technical ideas and development directions for the energy storage industry, but also further consolidated its leading position in the industry. In the future, Qualtech will continue to be market-oriented, driven by technological innovation, and continue to introduce more efficient, intelligent and safe energy storage solutions to contribute more to promoting global energy transformation and sustainable development.
