Zhuhai Jiuyuan is a leading domestic supplier specializing in power conversion and intelligent testing equipment for the new energy sector. The company has long focused on the R&D and industrialization of lithium battery performance testing, energy storage converters, and grid simulation systems. With its independently developed core technology—an "internal shared DC bus Jiuyuan has effectively addressed the industry's longstanding challenge of high energy consumption during testing. It provides high-precision, high-efficiency testing and energy management solutions for battery manufacturing, power laboratories, and energy storage systems.
As a technology leader in new energy power conversion and battery testing, Zhuhai Jiuyuan has developed a comprehensive product portfolio that includes battery testing systems, grid simulators, energy storage converters, and microgrid solutions. Known for high efficiency, precise control, and long lifespan, the company's products play a vital role in key segments of the new energy industry.
In battery performance testing, the company’s independently developed SDCBUS series testing systems leverage the innovative “internal shared DC bus” technology, achieving AC-DC conversion efficiencies of ≥98%—an industry-leading level. Utilizing multi-level topology control, these systems offer voltage/current measurement accuracy of ±0.01%. The core power unit features a wireless connection design that not only addresses the industry challenge of high energy consumption in traditional testing setups but also extends the device lifespan to over 25 years. Particularly in EV battery testing, the system supports a wide voltage range from 10 V to 2400 V, enabling full-parameter testing such as capacity and cycle life.
In the energy storage and microgrid domain, the company's PCS and converter products incorporate adaptive impedance reshaping technology, achieving peak conversion efficiency above 98.5%. Through smart dispatch algorithms and modular design, the systems meet the high power density requirements of C&I storage while ensuring stable islanding operation for microgrids. These solutions have been successfully applied in several integrated wind-solar-storage projects. The 5MW-class high-power converters have obtained TÜV Rheinland certification and are preferred by major energy giants such as the State Power Investment Corporation (SPIC).
