Recently, the 300MW/1.2G Wh grid-side independent energy storage power station in Zhangjiakou Chabei Management Area, a key construction project in Hebei Province, has been successfully connected to the grid with full capacity. This landmark achievement is not only a key step in the process of building a new power system and promoting green and low-carbon energy transformation in Zhangjiakou, but also injects new vitality into regional energy development.
As the core equipment supplier of the project, Qualtech can provide key equipment such as battery management system (BMS), high-voltage box and junction cabinet for the power station by virtue of its deep technical precipitation and rich practical experience in the field of energy storage, which effectively guarantees the smooth grid connection and stable operation of the project.
The battery management system (BMS) independently developed by Qualtech adopts advanced intelligent algorithm and multiple redundancy design. The algorithm can monitor the voltage, current, temperature and other key parameters of the battery in real time and accurately, and through large data analysis and prediction model, it can detect potential battery faults in advance, and realize all-round and fine management of battery status; Multiple redundancy design ensures the reliability and stability of BMS under complex working conditions. Even if some hardware fails, the system can still operate normally to ensure the safe and stable operation of the energy storage system.
In addition, Qualtech's high-voltage box is designed with materials and structures with high insulation and high protection level, which effectively improves the reliability and safety of electrical connection and can adapt to various harsh environmental conditions; The combiner cabinet integrates advanced intelligent monitoring and management technology, which not only realizes the centralized management and current collection of battery packs, but also monitors and analyzes the operation status of each battery pack in real time, further improving the overall performance and stability of the energy storage system.
The 300MW/1.2G Wh grid-side independent energy storage power station in Zhangjiakou Chabei Management Area is the first batch of grid-side independent energy storage demonstration projects in Hebei Province, and is also one of the largest grid-connected grid-side independent energy storage power stations in China. Located in the section area of North Hebei Power Grid of the State Grid, the power station is equipped with 240 sets of lithium iron phosphate battery cabins and 60 sets of converter and booster integrated machines. After full capacity grid connection, it can effectively alleviate the problem of limited new energy consumption in Bashang area and even northern Hebei area, which is of great significance to promote the regional peak power conservation in Zhangjiakou, maintain the safe and stable operation of the power grid, and promote the green and low-carbon development of the economy and society.
During the implementation of the project, the BMS provided by Qualtech, as the core component of the energy storage system, can monitor the battery status in real time to ensure the safe and efficient charging and discharging of the battery; the high-voltage box provides a reliable guarantee for the electrical connection of the energy storage system; the confluence cabinet realizes the centralized management and current confluence of the battery pack, and improves the overall performance and stability of the system. The high-quality supply and precise adaptation of these equipment have laid a solid foundation for the successful grid-connected and stable operation of energy storage power stations.
Qualtech focuses on the R & D, design, production and sales of new energy vehicle BMS and energy storage 4S + C core products (BMS battery management system + EMS energy management system + PCS energy storage converter + TMS temperature control system + Cloud big data intelligent cloud platform); At the same time, it provides overall solutions and implementation services such as energy storage system integration, integrated optical storage and charging system, intelligent energy management system, and micro-grid system for various scenarios. The company has been deeply engaged in the industry for 14 years. In the field of BMS segmentation, it is the leading enterprise in the two segments of new energy vehicle BMS and energy storage BMS in China.
This helped Zhangjiakou Chabei Management Area Energy Storage Power Station successfully connect to the grid, once again demonstrating Qualtech's strong strength in energy storage technology research and development and equipment manufacturing. In the future, Qualtech will continue to uphold and practice the development concept of "mastering independent core technology, independent manufacturing capability, and becoming a high-quality full-stack solution provider for digital smart energy systems", guided by market demand and driven by technological innovation, to provide customers with efficient, safe and reliable new smart energy system solutions; It will contribute more to the green and low-carbon transformation of energy and contribute to the sustainable development of global energy.
