Underwriters Laboratory to Toughen Lithium-Ion Battery Testing Standards
Underwriters Laboratories is re-writing the lithium-ion battery testing standards playbook, so to say.
This, says the UL, is the result of several high-profile battery-related incidents, most notably the grounding of Boeing’s 787 Dreamliner after battery incidents led to a fire in one of the aircraft.
UL will add additional safety tests, including an indentation induced short circuit test (as depicted in the image to your right).
Underwriters Laboratories says there have been more than 350 fires involving lithium-ion batteries since March 2012.
Underwriters Laboratories, in an article published on its website last week, stated:
“The number of lithium-ion batteries in use, the complexity of the lithium-ion battery cells and the numerous usage conditions make the design of safe cells and the development of tests for battery safety standards extremely challenging.”
“At UL, we are constantly developing new ways to help the world benefit from Sustainable Energy. Our global teams are working to advance the safety and security of the new processes, technologies and products that are transforming the energy industry. We are spearheading research and updating Standards to help ensure the safe commercialization of lithium-ion batteries.”
