On August 22, 2025, TÜV Rheinland Greater China (hereinafter referred to as “TÜV Rheinland”), a leading international testing, inspection, and certification organization, awarded Shenzhen Rui Jing Chuang Industrial Co., Ltd. (hereinafter referred to as “Rui Jing Chuang”) certificates for its energy storage connector series products: the 2PfG 2740 TÜV Bauart Mark certification and the UL 4128 TUVus North America certification. Mr. Luo Xuguo, General Manager of Rui Jing Chuang, and Mr. Hou Kun, General Manager of Solar and Commercial Product Services Accessories of TÜV Rheinland Greater China, along with other representatives from both parties, attended the certification ceremony.
Rui Jing Chuang focuses on providing professional and diverse connector products for new energy storage applications. The company has developed a full series of high-voltage, high-current energy storage connectors, including single-core energy storage connectors and maintenance switches (MSD), covering the series included in this certification test. These connectors are widely used in household and commercial energy storage systems for PACK series-parallel connections, as well as electrical connections with PCS inverters.
During product development, Rui Jing Chuang places great emphasis on safety and works closely with TÜV Rheinland to conduct rigorous testing and evaluation to ensure that product performance and safety comply with international standards. The awarding of the 2PfG 2740 TÜV Bauart Mark certification and UL 4128 TUVus North America certification by TÜV Rheinland provides authoritative assurance for Rui Jing Chuang’s products entering European and North American markets.
The European standard 2PfG 2740 for energy storage connectors sets detailed requirements for specific application scenarios such as electrochemical energy storage. Based on product definitions and declared usage environments, it adds targeted environmental resistance tests such as temperature cycling, thermal shock, and UV resistance to ensure product stability and reliability under different conditions. In addition, TÜV Rheinland, as a “Nationally Recognized Testing Laboratory” (NRTL) recognized by the U.S. Occupational Safety and Health Administration (OSHA), can simultaneously conduct U.S. product access testing and issue UL 4128 TUVus North America certification for energy storage connectors. Dual certification in both European and North American standards helps reduce enterprise costs and shorten market access cycles.
As a leading international third-party testing and certification organization, TÜV Rheinland continues to deepen its efforts in the energy storage industry and promotes healthy industry development. Rui Jing Chuang’s certification demonstrates that its products meet international market access standards and lays the foundation for future expansion into the global energy storage market.
