Chinese battery maker CATL said it entered into a Memorandum of Understanding with UL Solutions, an applied safety science multinational on battery safety and certification.
The strategic cooperation is designed to help create safer deployment and use of battery energy storage systems (BESSs) and electric vehicle (EV) batteries.
CATL’s battery laboratory will kick off the process to achieve UL Solutions’ UL 9540A, the Standard for Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems.
Once that is reached, CATL will be entitled to conduct witness test data programme (WTDP) tests at its test facilities under the supervision of UL Solutions. This will shorten time to market for battery products’ certification and testing.
CATL said it is the first company in China to launch the UL Solutions WTDP initiative for UL 9540A. It said it has diversified testing and verification capabilities, and has already been qualified by UL Solutions through the WTDP designation, to test to UL1973. This is 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 Standard for Batteries for Use in Electric Vehicles.
The battery firm said its EnerOne flagship outdoor liquid cooling battery system and EnerC, its containerised liquid-cooling battery system, have received the latest UL 9540A test report. That makes CATL the first Chinese company to receive such a test report in cell, module, unit and installation by UL Solutions.
The pair will also explore lithium-ion battery safety and help develop BESS and EV battery standards.
