Against the backdrop of the global energy structure transformation and the deepening of carbon neutrality goals, China's commercial and industrial energy storage market has entered a golden period of rapid development. According to the statistics and forecast data from the Energy Storage Research Institute of GGII, the shipment volume of commercial and industrial energy storage systems in China reached 7GWh in 2023, with a year-on-year growth of 240%. In 2024, the shipment volume is expected to reach 10GWh, representing a year-on-year growth of 42% compared to 7GWh in 2023. By 2025, the shipment volume of commercial and industrial energy storage systems in China is expected to grow by more than 50%. This significant growth is mainly attributed to the active promotion of national policies and the continuous growth of market demand, especially in regions with large peak-valley electricity price differences, where the peak-valley arbitrage model of commercial and industrial energy storage has demonstrated good economic benefits.
Against this backdrop, Qualtech has become a significant player and driver in China's commercial and industrial energy storage sector, thanks to its over 10 years of deep accumulation in battery management systems in the new energy field. The company focuses on the research and development, design, production, and sales of power BMS and the core control system of 4S+C for energy storage. It also provides overall solutions and implementation services for energy storage system integration, photovoltaic storage and charging integrated systems, smart energy management systems, and microgrid systems for various scenarios. Additionally, it can tailor solutions for different application scenarios based on customer needs. The company has participated in numerous demonstration projects and domestic and international energy storage projects, such as the 1.2GWh energy storage project in Inner Mongolia, the 600MWh energy storage project in Yunnan, the 500MWh energy storage project in Xinjiang, commercial and industrial energy storage projects in Europe, and Japan. Currently, it has applied energy storage systems exceeding 30GWh.
Backed by a solid business foundation and outstanding technological advantages, Qualtech's commercial and industrial energy storage business has witnessed a rapid development wave. 2023 is hailed by the industry as the first year of commercial and industrial energy storage in China, and it is also a year when Qualtech's market performance stands out particularly. The company's independently developed 215/233KWH liquid-cooled integrated outdoor mobile energy storage cabinet and its overall system solution, with their outstanding performance and flexibility, can be seamlessly integrated with various energy sources such as diesel generators, photovoltaic, wind power, and grid power, and are widely applied in various scenarios including temporary power supply in the wild, island applications, emergency power supply, power backup, and commercial and industrial uses.
Immediately following this, Qualtech Energy joined forces with the Energy Storage Research Institute of PetroChina to jointly create the first-of-its-kind distributed sodium battery energy storage cabinet in China. The company provided an overall system solution, and this product can meet the special fire protection requirements of scenarios such as oil fields, refineries, and gas stations. This collaboration not only highlights Qualtech Energy's leading position in technological innovation but also demonstrates its ability to provide customized solutions for special application scenarios.
The distributed industrial and commercial energy storage outdoor cabinet solution of Qualtech adopts the All In One design concept. The battery management system (BMS) adopts the industry-leading 2+1 level architecture, achieving the integration of intelligent data collection, analysis and diagnosis. At the same time, through the modular liquid cooling design, the fire protection system is integrated into the Pack, effectively enhancing the safety and efficiency of the Pack. This design not only meets the flexibility of outdoor deployment, but also effectively addresses customers' safety needs and concerns.
The company's independently developed smart cloud platform, with its zero-code compatibility, visualization of detection and operation data, and real-time AI intelligent scheduling functions, provides customers with a brand-new energy management experience. This platform can tailor the most suitable energy solutions for customers based on actual operation conditions, achieving the maximization of benefits.
It is worth mentioning that the company's domain control (EMU) technology can effectively monitor and protect battery stacks or clusters, accept energy dispatch from the platform, and achieve rapid fault isolation. During peak load periods, it can relieve pressure on the power grid, reduce operating costs, and enhance economic benefits, providing a more intelligent, user-friendly, and safe energy management solution for energy storage power stations, especially small-scale distributed energy storage. Through this technology, the safety and reliability of the energy storage system are ensured, and it also provides a strong guarantee for the stable operation of the power grid.
This solution integrates core subsystems such as EMS, BMS, PCS, and TMS. It can operate independently or in conjunction with photovoltaic systems to meet the needs of various industrial and commercial energy storage scenarios on the user side. Whether it is distributed power stations, industrial and commercial parks, smart buildings, residential communities, or distribution transformer area energy storage, Qualtech's products can provide strong support to ensure efficient, safe and reliable energy supply.
