As electric vehicles (EVs) become more widespread, ensuring lithium-ion battery safety during collisions is increasingly important. Mechanical impacts can cause internal damage, leading to short circuits, thermal runaway, or explosions. Protective enclosures help reduce deformation, but effective design demands accurate failure predictions. This webinar presents a comprehensive approach for modeling mechanical abusive loads on EV batteries, incorporating experiments, material characterization and the Sahraei Failure Criterion—a universal failure model based on microstructural simulations of the electrode-separator assembly. Model validations will be presented across various cell types and loading scenarios in commercial software such as Ansys LS-Dyna and Altair Radioss. Combined with multi-scale simulations, this framework supports the development of safer, more resilient battery systems for EVs.
This webinar will focus on the following key topics:
• Experimental Methods for Material Characterization
• Multiscale Modeling from Components to Cells and Battery Packs
• Short Circuit Prediction with Sahraei Failure
• Applicability to Pouch, Cylindrical and Prismatic Cells

Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7
Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.
The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.
The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires & explosions occur
• How to design safer batteries though understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter

Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway eventsPresenter
