  • How PSA tapes offer numerous advantages in EV battery pack design, including flame retardancy, ease of assembly, corrosion prevention, and end-of-life-recyclability

  • An overview of how to choose the right PSA tape for a specific application

• Propagation testing requires the intentional triggering of a single cell (or multiple cells) in a battery module or pack, to evaluate the ability of a specific battery design to reduce potential cell-to-cell propagation.

• This webinar discussed some of the common certification test methods currently utilized and the various requirements and criteria.

When repurposing EV batteries for stationary applications, new application-specific requirements must be validated on the repurposed packs.

One such test is propagation (otherwise called cell-propagation, thermal runaway, or single-cell-design tolerance).

As these test methods generally require modifications to an existing cell or battery pack to implement the test, repurposed batteries add a new challenge, as they are already manufactured, so modifications for testing must be implemented at the test site.

This webinar discusses these additional challenges and potential solutions for effectively performing these tests as well as potential preparation efforts that can be implemented on new EV batteries in expectation of future certification test needs.
