Recently, GBT's analysis and testing center was officially accredited by China National Accreditation Service for Conformity Assessment (CNAS). This accreditation signifies that GBT has reached national and international standards in terms of technological R&D and testing capabilities, further consolidating its leading position in the field of ultra-fast charging traction batteries.

China National Accreditation Service for Conformity Assessment (CNAS) is a national accreditation body approved and authorized by the Certification and Accreditation Administration of the People's Republic of China (CAAC) in accordance with the Regulations of the People's Republic of China on Certification and Accreditation. CNAS is responsible for accrediting certification bodies, laboratories, inspection bodies and other related organizations, and confirming their ability to carry out the corresponding conformity assessment activities through evaluation and supervision, and confirming the authority of their conformity assessment activities. CNAS accreditation is not only legally effective in China, but also enjoys wide mutual recognition and recognition in the international arena.

The analysis and testing center of Guangzhou Greater Bay Technology Co., Ltd. integrates three laboratories, including physical and chemical analysis of raw materials, battery performance testing and battery safety testing, equipped with international leading experimental equipment and testing environment, with a testing area of more than 10,000 square meters, more than 50 testing personnel and more than 2,000 sets of high-end equipment, with a total investment of more than 50 million yuan. The scope of CNAS accreditation capacity declared by the center this time covers 56 national standards, including testing of electrical performance, cycle life, safety requirements and raw materials of lithium-ion batteries for electric vehicles, providing comprehensive verification support for power batteries for new energy vehicles and ensuring the safety and reliability of power batteries. This CNAS accreditation is a strong proof of GBT's technical strength and professional ability, which not only means that GBT's test center has reached the highest national standards in terms of equipment, management, personnel and technology, but also marks the authority and international mutual recognition of its test results.

As one of the important development directions of the new energy vehicle industry, the research and development and industrialization of very fast charging batteries require strict technical support and testing guarantee, and this CNAS accreditation will provide strong technical support and guarantee for the promotion and application of very fast charging batteries in the international market. In the future, GBT will continue to uphold the development concept of innovation, pragmatism and efficiency, and continuously improve the technical research and development and testing capabilities, in order to provide new energy automobile industry with better quality traction battery products and services. At the same time, GBT will also actively work with domestic and foreign partners to jointly promote the rapid development and transformation and upgrading of the new energy automobile industry.
