UL Solutions, a global leader in applied safety science, and Contemporary Amperex Technology Co., Limited (CATL), a global leader in new energy innovative technologies, revealed an MOU for strategic cooperation to help build safer deployment and usage of battery energy storage systems (BESS) and electric vehicle batteries on January 17.
As the main component of the agreement, CATL’s battery laboratory will begin obtaining UL Solutions witness test data program (WTDP) status to test following UL 9540A, the Standard Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems.
Once granted WTDP designation by UL Solutions, CATL will be able to carry out WTDP tests at its test sites under the guidance of UL Solutions personnel, increasing the effectiveness and decreasing the timeframe to market for battery product certification and testing.
CATL and UL Solution progress
As the initial company in China to reveal the UL Solutions WTDP initiative for UL 9540A, CATL boasts a variety of testing and confirmation capabilities and has already been approved by UL Solutions through the WTDP designation to test to UL1973, the Standard for Batteries for Use in Stationary and Motive Auxiliary Power Applications, UL 9540, the Standard for Energy Storage Systems and Equipment, and UL 2580, the Criteria for Batteries for Use in Electric Vehicles.
CATL’s flagship outdoor liquid cooling battery system, EnerOne, and its containerized fluid cooling battery system, EnerC, have received the most recent version of the UL 9540A test report, making CATL the initial company in China to receive such a report at the cell, module, unit, and installation levels from UL Solutions.
Both sides will also use their expertise to conduct in-depth collaboration in further researching lithium-ion battery safety and providing insight into improving BESS and EV battery standards. The two companies will also collaborate to investigate carbon footprint reduction and other environmental practices.
Battery storage technologies are essential to speeding up the transition from fossil fuels with renewable energy and will play an increasingly pivotal role to help combat climate change and carbon emissions,
We are excited about our collaboration with CATL and how we are joining together to advance battery energy story systems and EV batteries applications as well as their safety and performance potential
UL Solutions’ executive vice president and president of Testing, Inspection, and Certification, Weifang Zhou, stated on their partnership
By cooperating with UL Solutions, we look forward to improving the scientificity and integrality of energy storage system safety testing, thus further enhancing our comprehensive testing and validation capabilities for energy storage systems,
We will further leverage our state-of-the-art battery technologies to facilitate the safe deployment and use of energy storage systems, thus speeding the global energy transition and creating a healthier, promising future for all
