Battery performance has continually presented challenges to EV efficiency, as the heavier weight of EVs – caused by heavy battery systems – means more frequent charging and shorter driving times. However, battery enclosure systems play a critical role in mitigating the impact of thermal runaway, a risk associated with lithium-ion batteries. Thermal runaway occurs when the lithium-ion cell enters an uncontrollable self-heating state that can produce fire, smoke, and extremely high temperatures while ejecting harmful particles.
“As the electrification of mobility continues to grow, thermal runaway has become a critical safety issue in the automotive industry and has drawn attention to how the optimal housing material is used for protection against thermal runaway,” said Eric Bulington, director of product management in UL Solutions’ Engineered Materials group. “With this offering, we are helping manufacturers address one of the most complex challenges in the e-mobility industry while meeting market demand for innovative and reliable automotive products.”
UL Solutions’ test methodology evaluates material performance by simulating a thermal runaway scenario. Assessments involve testing slabs of material against the entire battery, reducing testing costs and development time for resin manufacturers and material suppliers. Evaluations also focus on the selection of multiple formulations during research and development to provide material producers with the ability to offer original equipment manufacturers (OEMs) the solutions that meet their needs while taking into account the performance of the materials.
“UL Solutions has a long history of thought leadership when it comes to batteries of all shapes and sizes, so it’s fitting that we continue that legacy with EV batteries,” Bulington said. “With this offering, UL Solutions is addressing industry concerns by providing automotive OEMs and suppliers, as well as automotive component and system manufacturers, testing and consulting solutions to meet multiple standards and regulations. ”
