Propagation Test Requirements For Repurposed EV Batteries

• 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
