2024.12.10: Trina Energy Storage's self-developed "new generation of low-temperature resistant household energy storage battery system" has become the first battery R&D and manufacturer of overseas brands to receive this certification. It fully demonstrates the high reliability and safety of Trina's energy storage products and proves the strength of Trina's R&D certification team in deeply analyzing the local JIS standards in Japan.
As the industry's most stringent battery safety test, JIS C 4441 Thermal Propagation Test certification tests the resistance of system materials and structures to high-temperature conditions, as well as flame propagation control. By performing a forced thermal runaway test on the cells in the battery system it ensures that even if the battery cells burn, there is no open flame on the outside of the battery system box, and the box is not broken.
In the test, the single cell forced to thermally run out of control did not catch fire, and no fire was confirmed to be in other cells inside the battery system. After the occurrence of the overall thermal runaway and after a long period of observation, it was observed that the maximum temperature inside the energy storage system had rapidly dropped to a level of 10°C higher than the room temperature after 8 hours of thermal runaway and remained close to the room temperature level. The test results fully demonstrate the excellent fire and heat resistance of Trina Energy Storage as an energy storage system while significantly reducing the risk of flame propagation to other batteries or buildings, providing a solid foundation for safety assurance.
