Effects of Partial Nail Penetration on Li-ion Pouch Cell Operation
While many technological advancements have recently been made to ensure Li-ion batteries operate safely during normal cycling, many hazards exist when it comes to operation in abusive environments. Physical damage to batteries can lead to decreased performance and increased operating temperatures. This often causes thermal runaway, which in severe cases can lead to combustion and possibly explosion. In order to design cells in a way that mitigates these dangerous outcomes, it is important to understand what happens when a battery experiences physical abuse and continues to operate. This work focuses on the operational effects and indications for cells that operate in abusive environments where physical damage can be a concern.
This webinar will focus on the following key topics:
• Dynamic impact testing on Li-ion pouch cells
• Operational indications of cell damage
• Quantifying accelerated capacity fade due to physical damage
• Effect of increased operating temperature on coulombic efficiency
• Incremental capacity analysis for investigation into aging mechanismsPresenter
Casey Jones – Ph.D. Candidate at Purdue UniversityCasey Jones is a PhD student in the School of Aeronautics and Astronautics at Purdue University, where he works in the Interfacial Multiphysics Laboratory for Dr. Vikas Tomar. His research focuses on destructive testing of Li-ion batteries and the characterization of the effects on cell operation and is funded by the Office of Naval Research. Prior to studying at Purdue he served in the US Navy as a nuclear electronics technician aboard a fast-attack submarine based in Pearl Harbor, and received his BS in Mechanical Engineering from the University of Hawai’i at Manoa.

How to Safely Select DC Fuses for EES Systems
Proper selection of direct current (DC) overcurrent fuses is not as simple as it may seem, and several factors need to be looked at for proper selection. Design engineers need to look at many different things such as what we’re protecting, system voltage changes, circuit fault currents, minimum breaking currents, mechanical requirements, temperature deratings, system operation regarding cycling, etc. All of these and other factors need to be taken into consideration to safely select the proper DC fuse for each unique application. This presentation will take you through the basics of DC and AC fuses, DC circuit protection methods, and review EES fuse selection along with a case study. With the rapid growth of Electrical Energy Storage systems being implemented and deployed, we see an opportunity to educate everyone on this topic.
This webinar will focus on the following key topics:
• Fuseology
• Fuse Selection Practices
• DC Circuit Protection
• EES Fuse Selection Methodology
• Case StudyPresenter

Lithium-Ion Battery Patents – Understanding Infringement and Invalidity Through Recent Notable Litigation
This presentation will discuss recent notable decisions in U.S. litigation of lithium-ion patents, and what those cases can teach us about infringement and invalidity issues in lithium-ion patents. The presentation will focus on the role played by weight/volume claim terms, the duty of disclosure and invention disclosure statements during prosecution, the importance of quantitative examples in lithium-ion patent specifications, and properly presenting prophetic and working examples.
This webinar will focus on the following key topics:
• Recent notable decisions in U.S. district court and U.S. Patent & Trademark Office (IPRs) litigation of lithium-ion patents
• The infringement and invalidity of lithium-ion patent claims:
– The critical role of weight/volume (quantitative) claim terms
– How invention disclosure statements (IDS) can affect validity
– The importance of examples in a lithium-ion patent specification
– Properly presenting prophetic examples (predicted experimental results) as opposed to working examples (actual experimental results) in a lithium-ion patentPresenter

Best Practices for EV Cell Testing
In this webinar, we will begin with an overview of the typical structure of automotive EV programs, along with how the APQP phase gate process aligns to the key milestones of Automotive Component Verification (DVP & PVP) validation plans. Key considerations for testing progress tracking, reporting and the range of different tools and strategies will be discussed. This includes the importance of rigorous test procedure definition and equipment set-up verification to ensure highest quality data and reporting. A review the relevant standards will be presented along with examples of OEM specific testing areas. We conclude with a summary of the best practices our team has developed thru our EV testing programs conducted at Energy Assurance LLC’s Hopkinton test facility.
This webinar will focus on the following key topics:
• Typical EV program structure overview and APQP process
• Effective reporting and communication strategies
• Procedure definition and development
• Ensuring proper test set-up preparation and execution
• EV relevant testing standards and customer specific testingPresenter
