Recently, UL Solutions officially awarded CATL's Energy Storage Technology R&D and Verification Center with the world's first first-party UL 9540A accredited witness testing laboratory (WTDP) qualification. This milestone achievement not only demonstrates CATL's technical strength and excellent product quality control capabilities in the field of energy storage technology, but also marks a solid step forward for CATL in the global competition of the new energy market. As an important standard for evaluating the safety performance of energy storage systems, obtaining the accredited witness testing laboratory qualification for UL 9540A is undoubtedly a dual victory for CATL in technology and market.
WTDP (Witnessed Test Data Program) is an innovative service offered by UL Solutions, designed to assist customers in completing tests and collecting data through their own or third-party testing facilities, under the on-site witness of UL Solutions' engineering and technical experts. This service model breaks many bottlenecks in the traditional testing process, utilizing in-house laboratory equipment to conduct relevant product tests, significantly saving time on sample shipping, waiting for tests, problem rectification, and other related activities. It shortens the UL 9540A certification cycle for energy storage products exported to Europe, America, and other regions, and accelerates the speed of product launch. The recognition of CATL (Contemporary Amperex Technology Co., Ltd.) as a witness laboratory for UL 9540A is based on a successful practice within the framework of WTDP.
In the process of obtaining the UL 9540A accredited witness laboratory qualification, the CATL Energy Storage Technology R&D and Verification Center has demonstrated exceptional technical prowess and efficient testing capabilities. Equipped with advanced testing equipment and a professional testing team, the center is capable of conducting comprehensive safety performance testing on energy storage systems in strict accordance with the requirements of the UL 9540A standard. Meanwhile, under the on-site witness of UL Solutions engineering and technical experts, CATL can ensure the accuracy and reliability of test data, providing strong guarantees for the safety performance of its products.
It is worth mentioning that Jiangsu Firemana Safety Technology Co., Ltd., as a partner of CATL (Contemporary Amperex Technology), has provided CATL with a complete lithium battery thermal release rate testing system. This testing system is of great significance for evaluating the safety performance of lithium batteries under thermal runaway conditions and is an indispensable part of the UL 9540A standard. Leveraging its profound accumulation and technological advantages in the field of lithium battery safety testing, Jiangsu Fairman has provided CATL with high-quality testing equipment and professional technical support, helping CATL successfully obtain the world's first first-party UL 9540A accredited witness laboratory qualification. It is believed that in the near future, CATL will achieve even more brilliant achievements in the new energy field and contribute more to the prosperity and development of the global new energy industry.
