UL Solutions Introduces Battery Enclosure Thermal Runaway Evaluation, the First Test Method at UL to Help Screen Electric Vehicle Battery Enclosure Material

NORTHBROOK, Ill., July 11, 2022 /PRNewswire=KYODO JBN/ --

--Using a newly developed test method, automotive manufacturers and their

suppliers can safely compare performance of various materials to enhance

electric vehicle battery safety.

UL Solutions, a world leader in applied safety science, today announced the

Battery Enclosure Thermal Runaway (BETR) evaluation, the first material

screening test method at UL Solutions to evaluate electric vehicle (EV) battery

enclosure material. The offering based on UL 2596, Test Method for Thermal and

Mechanical Performance of Battery Enclosure Materials, was published on Jan.

27, 2022, by the UL Standards and Engagement organization.

Battery performance has continually presented challenges in EV efficiency, as

the heavier weight of EVs -- caused by heavy battery systems -- means more

frequent charging and shorter drive 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 particulates.

"As the electrification of mobility continues to grow, thermal runaway has

become a critical safety issue in the automotive industry and has heightened

attention concerning how optimal enclosure material is used for thermal runaway

protection," said Eric Bulington, director of product management in the

Engineered Materials group of UL Solutions. "With this offering, we are helping

manufacturers navigate one of the e-Mobility industry's most complex challenges

while meeting the market demand for innovative and trustworthy automotive

products."

The UL Solutions testing methodology evaluates material performance by

simulating a thermal runaway scenario. The evaluations entail testing material

plaques versus the entire battery assembly, reducing testing costs and

development time for resin manufacturers and material suppliers. Evaluations

also focus on screening multiple formulas during research and development to

provide material producers the opportunity to offer original equipment

manufacturers (OEMs) the solutions that meet their needs while also considering

performance among materials.

"UL Solutions has a long history of thought leadership with respect 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 addresses

industry concerns by providing automotive OEMs and suppliers, and automotive

component and system manufacturers, testing and advisory solutions to meet

multiple standards and regulations."
