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.

Here’s a Glimpse of What’s Going on at UL in Regards to Battery Safety

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.”

    Apparently exploding cell phones and lap-tops catching on fire weren’t severe enough to update the standards. But now that we have planes & cars using them, we need to look into this more.

    Similar to Ground earth clamps in Australia, in the last decades they are a joke,
    Guess after a few people a electrocuted Standards Australia may update the standards ?

    I believe the term is “coffin engineering” ?
    When the body count is high enough – sure we can amend the standards!

      If you can apply this type of “engineering” to illegal firearms, will that reduce crime?
